Abstract

Northwest Shanxi is located at the eastern border of the Loess Plateau. In order to guard against wind, to conserve water and soil, to fix sand, a large area of Caragana microphylla was planted in the hilly loess plateau in the north-west soil properties and ultimately soil quality, a case study was conducted in Wuzhai (North-west Shanxi Province). Soil samples were collected from adjacent Caragana microphylla land, farm land, poplar forests, fallow land and mixed plantations of Caragana microphylla and poplar. Initially, soil properties under the five land-uses were studied separately. Then an evaluation indicator system was developed according to the principle of evaluation indicator selection. Subsequently, the method of multivariate analysis was used to carry through a complete scientific evaluation. Results showed a highest under the mixed plantation and, compared with the mixed plantation,the SQI of farmland decreased greatly. The SQI of fallow land was the lowest, but considering the soil nutrient content, land fallowing improved soil fertility to some extent. It was further shown that growing Caragana microphylla and mixed polar and Caragana microphylla plantation was the most sustainable ways of developing the loess plateau.
