基于耕地系统内部的要素-过程-功能分析,建立"需求-功能-维度"的耕地健康评价理论框架,构建评价指标体系,运用综合指数法、"1+X"累加模型、最小因子法测算耕地健康状况,并以大兴区为例进行验证。结果表明:1)明晰了耕地健康的内涵并从生产能力、耕地弹性、生产环境和产品品质4个维度构建了耕地健康评价指标体系;2)大兴区耕地图斑的生产能力、耕地弹性和生产环境指数分别为1 135.81～2 807.23、63.95～94.67、0.40～1.00,产品品质指数为100;3)区域内耕地健康等级包括健康、亚健康和病态3种,无不健康耕地,各级别耕地面积分别为4 726.51、19 333.12、16 754.94hm2,耕地健康评价结果地域分异明显。本...

Based on the factor-process-function analysis within the cultivated land system,the framework of the cultivated land health of demand-function-dimension was established and a cultivated land health evaluation index system was built.The comprehensive index method,“1+X”accumulation model and the minimum factor method were applied to evaluate the health status of cultivated land by taking Daxing District as an example for verification.The results indicated that:Firstly,the connotation of cultivated land health was put forward and the cultivated ...
