河南省农田承灾力初步分析与评价

The Synthetic Appraisal and Regional Division of Farmland Hazard-bearing Capacity in Henan Province

对农田承灾力的研究,目前还刚起步,研究的方法与步骤至今尚处在探索阶段。本文是从建立农田承灾力的评价模型入手,研究各参评因子的评分标准,各因子的权重分配,最后进行等级划分。以河南省为例,从理论到实践,按照评价模型,分别对全省一百多个县(市)的农田承灾力进行系统分析与计算。最后分豫北、豫东、豫东南、豫西南、豫西、豫中等六个区进行综合分析与评价。

Taking Henan province as an example, this article starts with the establishment of evaluation model of farmland hazard-bearign capacity, then studies the marking criterion and weight distribution of each element, last makes the division of grade.
