欠发达地区耕地集约利用评价——以张家界市为例

Study on the Cultivated Land Intensive Use in Underdeveloped Areas:A Case Study of Zhangjiajie

为准确认识欠发达地区耕地集约利用状况,以张家界市为例,采用变异系数法与综合指数法相结合的方法计算耕地集约利用综合指数,根据计算结果对其时序变化进行评价分析,并运用Arc GIS平台进行空间分析,以期为其他欠发达地区耕地集约利用评价的研究提供参考。

To understand the situation of cultivated land intensive use in underdeveloped areas, this paper takes Zhangjiajie as an example, and uses the method of coefficient of variation and comprehensive index to calculate the comprehensive index of cultivated land intensive use. Then, evaluates and analyses the time serial change according to the result of calculation, and makes a spatial analysis by using ArcGIS to provides reference for the study of inten- sive utilization of cultivated land in other underdeveloped areas.
