摘要: 应用指数和法探讨了北京市大兴县 1982年~ 2 0 0 0年土壤肥力的变化特征 ,并对其影响因素进行了评价和分析。研究结果表明 ,近 2 0a来 ,土壤肥力总体上呈上升趋势。尤其在 90年代 ,由于农业种植结构的调整以及秸秆还田 ,使土壤有机质含量持续上升 ,土壤的综合肥力显著提高。

Abstract: IFI was introduced and used to analyze the temporal changes in soil fertility in Daxing County,and the factors affecting these changes as well.Results show that soil fertility has been raised as a whole in the past twenty years,and especially was in the 1990’s.Thanks to the adjustment of cropping structure and return of straws,the soil IFI has been increasing steadily and so has the integrated soil fertility in this county.

Key words: Beijing Plain, change, integrated evaluation, soil fertility
