摘要
在对开采沉陷耕地的土壤特性和作物产量连续3年测试的基础上,运用模糊数学方法,对开采沉陷耕地的生产力进行了定量评价,揭示了开采沉陷耕地生产力下降的规律,并指出了导致其下降的主要原因.
Based on the analyses of soil properties and crop yields of subsided farmland in three successive years, the quantitative evaluation of the productivity of subsided farmland is made by applying fuzzy mathematics method. The research reveals the laws of productivity decrease of subsided farmland, and the primary factors resulting in the decrease of farmland productivity are also pointed out.
