Research on Evaluation Model for Sustainable Use of Farmland in Soil Erosion Area

Based on the results of research on the effects of cropping patterns on soil productivity and soil environmental of cropping patterns on soil productivity and soil environmental quality in soil erosion areas, resource accounting and simulation modelling methods were used for discussing the evaluation models of different cropping patterns for sustainable farmland use. The results of case study in Wenxi County of Shanxi Province showed that the evaluation models are feasible and successful for continuous evalation of agriculture.
