Analysis of plant diversity of railway cutting slopes in Sichuan Province
Through a comparison of the plant species diversity of different railroad slopes after vegetation restoration(natural or artificial) and the undisturbed slopes,we discovered that the restoration outcome varied with restoration periods,soil matrixes and slope locations.Long restoration periods,or places with loose soil or better aboriginal vegetation tend to produce higher vegetation richness.This demonstrated that the physical and chemical property of the study area's soil as well as the succession pattern of the native community should be taken into consideration when to launch an artificial restoration.Priority should be taken to the indigenous species when choosing the pioneer species,but to introduce foreign species could be useful if the richness of the indigenous species is less in the areas.

Contrast between bioengineering and masonry structure in slope project
Slope bioengineering and masonry structure engineering are the commonly used types for slope protection.Slope bioengineering has significant protective effect on ecology environment,yet vegetation has complex effect on the stability of slope,it plays both positive and negative roles.Masonry structure can inhibit the erosion of the slope caused by rainstorm,but it has not reinforcing function of the shallow soil.The impact principle of it is to keep the water from slope so as to avoid disaster.The inhibition of erosion provided by vegetation cover is remarkable,and it has reinforced action on the shallow soil.But the limitations of biotechnical slope protection is obvious,and it has the possibility to induce the deep seated landslide.This paper analyzed both effectiveness and shortcoming of bioengineering through mechanical effect and hydrological effect,and it may provide a good reference to find the ideal slope protection measures which can utilize the excellences for both bioengineering and masonry structure.

Measurs to assure effect of mine eco-environment control
It is necessary to reconstruct abandoned mines,though there will be many difficulties when conducting.According to the abundant experiences in ecological environment control of abandoned mine,the(author)suggested a series of measures to ensure and to reach the best control effect.Firstly,a considering of comprehensive revegetation work and a suitable design should be made;secondly,proper slope clearing work should be done to stabilize slope,so as to afford a base for vegetation restoration;thirdly,the artificial soil should have proper structure,enough nutrient,good fertilizer and water conservation ability,good anti-erodibilities,and can be sprayed on the slope firmly;fourthly,choosing correct plant species and allocation of them;finally,in the management and maintenance of the artificial vegetation,watering,fertilizing,reseeding,soil mending,and disease or pest control were necessary.By those measures,a stable,harmonious,sustainable plant community in the ecological environment of abandoned mine could be constructed firmly.

Slope revegetation methods and its selection
At present,there are no uniform standards or rules about slope revegetation,and series of problems exist in practice.The author proposed some advices to the methods,design and supervision of slope revegetaiton,which were based on long term work experience.In this paper,principles,advantages and disadvantages of different slope revegetation method were addressed in detail,and supervision rules were proposed too.Recovering vegetation and conserving ecosystems should be the final aim of slope revegetation,and adapting the nature with suitable sites for greening should be the main principle.All those can offer conferences for the development of slope revegetation.

Choice and establishment ways of plant in implementing medium-spraying technique
In artificial construct process,particularly in the practices of highway,railroad,mining,water conservancy,mountainous architectures,different types of rock slope were formed.,The medium spray technique is currently in common use to recover the ecosystem of plant in rock slope,In order to achieve the goal of building objective community,we need to research the natural environment including weather,soil,vegetation,and analyse the characteristics of the slope,such as the landform of the slope,slope gradients,and the stability.In choosing the target plant,the priciples of ecosystem adaptability,pioneering,harmonizing,resistance to severe factors,as well as self maintaining,bio-diversity,sustainable stability etc.should be satisfied.The revegetation should adopt a combination of direct seeding and tree planting to help the steady rehabilitation on the rock slope.
