县域土地资源利用的环境友好型评价——以河南省长葛市为例

Environment-friendly Evaluation of Land Use at County Scale——A Case Study of Changge City,Henan Province

本文在探讨土地资源利用环境友好型的概念与内涵的基础上,从生态环境、经济和社会三个方面,构建了土地资源利用环境友好型评价的基本框架,建立了县域尺度上土地利用环境友好型分级系统及分级标准,并提出了综合指数法与单指标多角度评价法相结合的土地资源利用环境友好型评价方法。以河南省长葛市(县级)为例,采用综合指数法与单指标多角度评价方法相结合的评价方法,评价了该市土地资源利用环境友好型状况。结果表明,就该市的土地利用在生态环境友好型、经济可行性和社会可接受性三个方面都相对较好,其中,2000年属于不友好阶段,2001～2002年属于临界友好阶段,2003～2009年属于基本友好阶段,且利用水平有逐年提高的趋势。
