摘要
在生态文明的视角下,以忠县为例,对三峡库区耕地集约利用水平进行分析.利用PSR框架,通过构建评价指标体系,利用熵值法确定其权重,构建加权平均评价模型,测算出忠县耕地集约利用水平,其中忠州镇、乌杨镇和复兴镇等11个乡镇耕地集约度较高,石子乡、金声乡和兴峰乡等17个乡镇耕地集约水平较低.其研究结果表明:忠县耕地集约利用总体水平较低,有效土壤层厚度、坡度等自然条件对耕地集约利用水平影响较大,耕地集约利用水平空间分布差异明显,耕地投入较少,集约利用水平发展空间较大.最后提出了提高耕地集约利用水平的建议:加强土地整治,提高耕地质量,促进生态文明建设;优化耕地集约利用空间结构,构建新型农业经营体系;加大农业投入,走现代农业道路和建立耕地保护监管体系等.
This essay ,from the perspective of ecological civilization and with Zhongxian as an example ,is related to the analysis of the intensity of utilization of cultivated land in Three Gorges Reservoir region . The research has been launched to establish the evaluation index system ,to calculate its weight in the en‐tropy method ,to establish model of the estimate weighted mean （average） ,and to calculate the intensity of utilization of cultivated land in Zhongxian .11 tow ns or tow nships of Zhongxian in total ,such as Zhong‐zhou ,Niaoyang and Fuxin ,etc .,are ranked the top ,w hile 17 tow ns or tow nships in total ,such as Shizi , Jinsheng and Xinfeng ,etc .,lag behind .T he result show s that the overall intensity of utilization of culti‐vated land in Zhongxian remains low ;Effective soil thickness ,slope and other natural conditions a greater impact on the level of intensive land use ;the spatial distribution differs greatly .Finally ,the advice for im‐proving intensity of utilization of cultivated land is put forward to intensify land reclamation ,to improve quality of cultivated land ,to promote eco‐civilization construction ,to optimize spatial structure of inten‐sive utilization of cultivated land ,to construct new agricultural management system ,to increase agricultur‐al investment ,to track modern agricultural path and to establish protection and supervision system of cul‐tivated land and so forth .
