Soil anti-scouribility of water conservation forests and its affecting factors in Simian Mountain，Chongqing City
Soil anti-scouribility for four different water conservation forests in Siman Mountain of Chongqing was studied by the flume experiment. Also its dynamics over time and its influencing factor including slopes and root system was discussed. Results indicate that: Soil anti-scouribility of Phyllostachys pupescens land was the best, followed by conifer+broadleaf forest land and conifer forest land, the worst was in broadleaf forest land. Soil anti-scouring indices in turn were 20.153, 14.717, 10.819, 4.615L·min/g. Soil anti-scouribility of A0 was much better than A, and it occurred an exponential relation over time. The 25° was a turning point of soil anti-scouribility. The roots of <3mm were the main component of surface soil in this area, therefore soil anti-scouribility of A0 was affected by the root biomass of <1mm roots, 1-3mm roots and 3-5mm roots and by the root dead biomass, and soil anti-scouribility of A was affected by the root biomass of 3-5mm roots and by the root length of 3-5mm roots.

Erosive rainfall and rainfall erosivity in purple hilly area
The spatial distribution of rainfall erosivity could reflect the role of the regional climate for soil erosion. Based on measured rainfall data for many years, frequency analysis method was employed to calculate the general rainfall standards of the erosive rainfall, and the erosive rainfall and its soil erosion characteristics were analyzed in the purple hilly area in Sichuan Basin. The rainfall erosivity was calculated using daily rainfall amounts and the spatial-temporal characteristics of rainfall erosivity were analyzed. The results showed that: 1) The general rainfall standard of erosive rainfall of the downslope cultivation land was 11.3mm. 2) Over 60% of rainfall events were erosive rainfall. Erosive rainfall mainly fell on May to September. The erosive rainfall amount and soil erosion amount in the July and August was the largest. To the spatial distribution, the erosive rainfall of the edge region was greater than that of the central region. 3) The annual average rainfall erosivity value was between 5000 and 6500MJ/ (mm·hm2·h). It decreased from the edge to the central regions gradually, and was greater in the northern and western area than the southern and eastern areas. The annual average rainfall erosivity of the Bazhong station, Daxian station and Langzhong station in northern area formed the high value area, and the Suining station in central area formed the low value area. The rainfall erosivity was mainly composed by ≥15mm rainfall events, accounting for 76.9%-82.1% of total rainfall events. It was mainly distributed in flood season (between May to October) and accounted for more than 89% of annual rainfall erosivity. The interannual variability of rainfall erosivity was larger up to moderate variation, but did not occur to obvious increase or decrease trend over time.

Concept and calculation methods of erosion control degree:A case study of the Wangmaogou Watershed
In this paper, the erosion control degree was defined as the ratio of the minimum possible soil erosion modulus and actual soil erosion modulus. The minimum possible soil erosion modulus was 2573t/(km2·a)) under soil and water conservation measures in Wangmaogou Watershed. Based on the land use map in 2004, the actual soil erosion modulus of Wangmaogou Watershed was 7413t/(km2·a). According to the definition of the erosion control degree, the erosion control degree of Wangmaogou Watershed was at a lower level of 0.35, due to existed sloping farmland and less forestry area. Therefore, we suggested that erosion control degree should be as the evaluation indicator for the status of soil and water conservation.

Response of ecosystem service values to land use change based on GIS and ecological compensation in Loess Plateau
The Loess Plateau is the most serious soil erosion areas in China, where the land use changes would lead to the various ecological and environmental problems, which has been one of the hot issues around the world. By taking the whole Loess Plateau region as the research object, the land use changes between 1985 and 2005 was studied and the reasons of the changes were analyzed based on GIS technology. The effect of land use changes on the ecosystem service was evaluated quantitatively and an appropriate eco-compensation standard was preliminarily developed. The results show that: 1) the main type of land use was grassland and farmland, accounting for over 75% of total land use. Among them,the area of farmland was reducing, and the area of woodland was increasing; 2) Settlement was the most active land use type. Settlement and waterland were expanding between 1985 and 2005; 3) Land use changes impacted the regional eco-environmental effects. The total value of ecosystem services rose 0.01%, in which woodland had the biggest increase about 0.09% and the largest decline occurred in farmland about 0.02%. The total ecosystem services of the Loess Plateau were increasing, except the values of waste treatment and food production relating with farmland and wilderness; 4) According to the values of ecosystem services of Loess Plateau, the eco-compensation standard was 427.32 million yuan.

Grain size characteristics of gobi sediment in Ejina Basin
The surface and sublayer gobi sediment grain size composition, average grain size, sorting coefficient, skewness and kurtosis were analyzed by collecting sediment samples in field and testing grain size characteristics in laboratory. The results show that except for the top of alluvial-proluvial fan, the majority grain size of surface sediment was occupied by stone, but that of sublayer sediment was sand. In surface sediment, the mean grain diameter was relatively large composed by stone and gravel, but in the sublayer, the mean grain size had significantly thinner trend. Therefore, the average grain size changed smaller from low residual mountain to alluvial-proluvial fan edge. The grain sorting in different sediment layers was poor or poorer, but only was medium on low residual mountain and nearshore lake shallow. The grain skewness of surface sediment was positive or very positive, accounting for 76.93% of the total sampling，while the skewness of sublayer sediment was negative or very negative，accounted for 84.62% of the overall sampling. Kurtosis frequency curve of grain size in surface sediment was sharp or very sharp，accounting for 69.23%，followed by medium, accounting for 15.38%，while in sublayer sediment was flat, very flat or medium, accounting for 76.93%. In general, gobi sediments appeared the characteristics of coarse grain size, bad sorting, positive skewness and sharp curve features, which reflected the sedimentary environment, morphological characteristics, erosion and deposition pattern. The results could provide the reference for the gobi classification.

Change in runoff and sediment in the upper catchment of Beiluo River under the vegetation restoration
Grain for Green program since 1999 resulted in a great land use/cover changes in the Loess Plateau, China, which fundamentally influenced hydrological cycle and sediment transportation. It is important to understand the impacts of soil and water conservation measures on the streamflow and sediment load in the catchment. The double accumulative curve and Pettit Test method were employed to identify trend and change point in the runoff and sediment in the upper catchment of Beiluo River from 1980 to 2009. Combined with the data of climate change and measures of soil and water conservation, the runoff and sediment process at monthly and yearly scales were analyzed. The result showed that: 1) the change points in 2002 was detected for both runoff and sediment. Compared to period 1(1980—2002), the volume of runoff and the sediment discharge in period 2(2003—2009)decreased by 0.32×108m3, 0.29×108t respectively, and with less fluctuation. 2) At monthly scales, the patterns of monthly rainfall amount and monthly mean volume of runoff in both periods were similar. The relationship between monthly mean volume of runoff and sediment delivery was showed as clockwise 8, but the varying ratio was different.3) Compared to period 1, the annual average rainfall amount and the annual average rainfall erosivity increased by 10.06% and 10.28%. The rainfall has the potential capability of reducing the runoff and the sediment .Regardless of the effect of rainfall, the effect of reducing runoff and sediment by forest and grass measures were about 41% and 81%, respectively.

Discussion on the categories and methods of soil and water conservation monitoring in China
According to the nature of the work, the monitoring of soil and water conservation in China can be divided into four categories as followings: studying monitoring, experimental monitoring, productive monitoring and predictive monitoring. Currently four categories of monitoring are nested within each other and of mutual dependence. Therefore, we must cognize the actuality of the stage development accurately, and analyze the relation between each category dialectically, then keep on the right direction of development. In the future, we should strengthen the study of monitoring theory and experiment, at the same time, enhance the practice and improve the institutional systems and standardize management and reinforce the train of staff. Therefore the development of soil and water conservation monitoring in China can be promoted more scientific, comprehensive and sustainable.

Spatial variability of soil thickness in a small watershed of Karst plateau
Soil thickness is one of the most important factors restricting the ecological restoration in the region of Karst plateau. A case study was conducted in Wujinghe small watershed in Guizhou Province, China. The aim of this study was to characterize the spatial variability regulation and distribution pattern in soil thickness in Karst plateau. The soil thickness of three typical landuse types was measured in October, 2010 and analyzed by using traditional statistics and geostatistics methods. The results show that the degree of spatial variability in soil thickness in this study area was overall moderate, but strong in a few plots. All three landuse types had good semi-variance structure, and the spatial variability decreased with the decrease in slope position. The soil thickness was increased with the decrease in slope position. Relatively good spatial correlation and continuity of soil thickness exist between different sloping farmland. On the contrary, the degree of spatial variability in soil thickness was larger in both the barren hilly and Populus euramevicana plantation, and its spatial pattern came out as fragmentized distributions. Soil thickness can be well expressed by exponential model（R2≈0.8）in almost all plots, but fitted with spherical model and Gaussian model in a few plots. The research findings can provide deepen understanding of soil thickness, which will provide the foundation for Karst rocky desertification control project and rational utilization of land resources in Karst plateau region.

Fractal characteristics of soil particles and soil water retention curve under typical vegetations in mountainous land of central southern Shandong
Soil particle size distribution and soil water retention curve as important physical attributes had important effects on soil erosion and productivity. Based on fractal theory, fractal characteristics of soil particle size distribution and soil water retention curve under five typical vegetations were studied in mountainous land of central southern Shandong. Results indicate that: 1) Monofractal dimension and multifractal parameters of soil particle and fractal dimension of soil water retention curve under different vegetation forms varied greatly, and all showed that: mixed plantation of Quercus acutissima Carr. and Robina pseudoacacia Linn. > mixed plantation of Pinus thunbergii Parl. and Pistacia chinensis Bunge >Pinus thunbergii Parl. > Juglans rigia Linn. > deserted grassland. 2) For the soil fractal dimension,woodland was significantly higher than deserted grassland, and mixed forest was higher than pure forest.3) Fractal dimension of soil had a significantly positive correlation with silt and clay volume content, but a significantly negative correlation with sand volume content. 4) The monofractal dimension of soil particles had significant positive correlation with that of soil water retention curve. A well linear correlation was found between the monofractal dimension of soil particles and fractal dimension of soil water retention curve, which showed that fractal parameters of soil particle size distribution and soil water retention curve could be taken as quantitative indices to reflect soil physical properties. Relationship between fractal dimensions of soil particles and soil water retention curve could be used to describe corresponding soil water retention curve. The results in this paper could be a guidance and theoretical basis for the projects of the coversion of cropland to forest and ecological forest afforestation and their benefit evaluation.

stress on photosynthetic physiology of garden plant seedlings
Taking Bauhinia blakeana, Elaeocarpus apiculatus, Mangifera indica, Alstonia scholaris, Bischofia javanica, Cinnamomum camphora, in Guangzhou City as test objects, a pot experiment was conducted to study the photosynthetic characteristics of these seedlings under effects of artificial simulation of the fumigation experiments with a gradient of 2.86mg/m3 of SO2 concentration (LSO2), 5.72mg/m3 of SO2 concentration (HSO2) and relatively clean area (CK). Results showed that：1) Compared with CK, the maximum net photosynthetic rate of six garden plants seedlings showed a downward trend with the increase of the concentration of SO2. Under two concentrations of SO2 stress, LSO2 and HSO2, the maximum net photosynthetic rate of Bauhinia blakeana, Elaeocarpus apiculatus, Mangifera indica, Alstonia scholaris, Bischofia javanica, Cinnamomum camphora decreased by 20.96% and 38.35%, 45.32% and 52.17%, 69.21% and 71.19%, 58.30% and 61.88%, 43.90% and 56.10%, 25.26% and 40.34%. 2) Light saturation point of Bauhinia blakeana, Mangifera indica, Alstonia scholaris, Bischofia javanica, Cinnamomum camphora ranged from 748-1016μmol/(m2·s), while their light compensation point ranged from 4.0 to 9.3μmol/(m2·s), and showed strong photophilic and shade-tolerant characteristics in a relatively clean area. Compared with CK, light saturation point of six kinds of garden plants occurred reduction to some extent. The largest decline of light saturation point was occurred in Mangifera indica, Alstonia scholaris, Bischofia javanica, while the smallest decline was in Cinnamomum camphora. 3) The effect of concentration of SO2 stress on light compensation point of six kinds of garden plants was not obvious. Under the stress of SO2 pollution, light adaptation range of six kinds of plants would be narrowing and poor. 4) Bauhinia blakeana and Cinnamomum camphora maintained the higher net photosynthetic rate and water use efficiency, and had higher adaptation ability to SO2 stress. The results would provide a reference for plants selection of severe acid contaminated areas such as thermal power plants, ceramic plants, steel mills and petrochemical plants.

Discussion on monitoring methods and prediction models of wind erosion in production and construction projects
Acquiring accurate wind erosion amount is very important in the studies of wind erosion in the production and construction projects. It is helpful for the compilation of soil and water conservation schemes and for the prevention of soil and water loss. The studies on monitoring methods and prediction models, however, are still not enough. In some existent studies, it needs to think more about the suitability of monitoring methods and the accuracy of factors in different models. In order to provide production and construction projects with useful supports, this paper hence summarized monitoring methods and prediction models, which are applied widely in wind erosion. According to the respective characteristics of these methods and models, the suitability of them in production and construction projects has been analyzed.
