干旱内陆河流域土地利用变化的人文驱动因素探究——以甘肃省酒泉市为例

The Human Driving Forces to the Land-use Change in Arid Inland River Basin—the Case Study of Jiuquan City

根据甘肃省酒泉市1997-2006年土地利用变更数据,分析了土地利用类型的数量变化特征,在Matlab软件背景下运用主成分分析法,并从定性与定量的角度探讨了土地利用变化的人文因素与驱动机制。结果表明:人口、农业化水平、社会经济及政策是影响土地利用变化的主要人文驱动因素,其中人口因素持续性地影响着土地利用变化,而政策对土地利用变化的影响起着主导性的作用。

Based on detailed survey data of land use from 1997 to 2006 in Jiuquan city, Gansu province, the characteristics of land use changing were analyzed during the period, and the human driving factors of land- use change was discussed. In the background of MATLAB, the study focuses on human dimension. Quali- tative and quantitative analysis indicate that the dominant driving forces include population, growth, the de- velopment of urbanization, agricultural modernization, economic development and policy. Population is continuing factor, policy plays a leading role in land-use change in Jiuquan city.
