摘要

基于张掖绿洲1998-2007年土地利用和自然、社会、经济数据

采用数理统计分析方法

定量综合探讨耕地和建设用地变化驱动力。结果表明

社会经济因子对耕地、建设用地变化驱动方向和大小表现出差异性; 其次

主分量驱动因素的影响作用方向和大小也不同

即对于耕地面积的变动来说

经济发展水平和经济结构都是负向驱动

而对于建设用地面积变动都是正向驱动; 相同驱动因素的影响敏感性也表现出差异性。

Abstract

This study is based on the year-by-year investigation of nature

society

and economy in Zhangye City from 1998 to 2007. Driving forces of the changes of cultivated land and construction land were analyzed synthetically and quantitatively using mathematical statistics methods in order to discover the similarities and differences of driving forces. Results indicated that driving factors display a certain difference. At the same time

the direction and size of principal component factors are different. The level of economic development and economic structure factors make a negative driving to cultivated landuse change

but a positive driving to construction landuse change. The research result contributes to the quantitative and comparative under standing of driving forces on cultivated land and construction land and points out a way to the research on landuse change mechanisms.
