水土流失地区农田可持续利用的评价模型研究

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

通过水土流失地区不同农业生产方式对土地质量及土壤生产力的影响研究，探讨不同作物及其不同的种植方式对农田可持续利用的评价预测模型及土地资源利用的价值核算方法。通过对山西省闻喜县的案例应用验证，表明了在农业可持续发展研究中应用的可行性。

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.
