Abstract:[Background] As a pioneer species of soil and water conservation forests, Hippophae rhamnoides is widely planted in the water-wind erosion interlaced region of the Loess Plateau. Information on its adaptability and effects on soils is valuable for the management of forest land in this area. The growth and development of H. rhamnoides may change soil physical and chemical properties which will affect the plant growth as a feedback. That is, there may be a certain coupling relationship between soil and vegetation. Studying the coupling relationship between soil and H.rhammoides may provide a theoretical basis for the sustainable management of H. rhamnoides forest.[Methods] Based on the soil physiochemical properties and growth status of vegetation of H. rhamnoides community in typical converting farmland to forest area in Wuqi county, Shaanxi province, variance analysis method was used to determine the differences in soil physical and chemical properties among different soil depths, stand types and slope aspects. Principal component analysis was used to compare the differences in soil physical and chemical properties of different stand types of H. rhamnoides. The gray correlation model was used to analyze the correlation between soil factors and tree height, basal diameter of H. rhamnoides and herb layer biomass under H. rhamnoides forest.[Results] 1) The soil physical and chemical properties of H. rhamnoides community varied significantly in different soil depths. Stand type and aspects had significantly interactive effect on soil total nitrogen and capillary porosity. Soil total nitrogen and capillary porosity of the Pinus tabuliformis+H. rhamnoides on sunny slope were significantly higher than those on shady slope and other stand types. 2) Soil organic matter, total nitrogen and capillary porosity were the dominant factors reflecting the soil physical and chemical properties. The pure H. rhamnoides forest on shady slope and the Pinus tabuliformis+H. rhamnoides on sunny slope exhibited higher soil improvement. 3) The order of average gray correlation degree between the H. rhamnoides community and soil factors was capillary porosity > total nitrogen > organic matter > non-capillary porosity > available phosphorus > soil density > available potassium.[Conculsions] There is a strong mutual promotion between the growth of vegetation in H. rhamnoides community and the improvement of soil physical and chemical properties. Therefore, H. rhamnoides is suitable for being planted in the loess area of northern Shaanxi. In order to promote the improvement of soil by H. rhamnoides to achieve the purpose of vegetation succession, the pure H. rhamnoides forest on sunny slope is suggested as the transformation of Pinus tabuliformis+H. rhamnoides, while the pure H. rhamnoides forest is more suitable for shady slope.
