内蒙古包头市九原区土地利用变化及驱动因子研究

Study On Changing and Driving Forces of Land—Use in JiuYuan District of Baotou City

包头市郊区原为包头市九原区,属农牧交错、城乡交错地带,生态环境脆弱,农用 地与建设用地矛盾突变,本文以系统论、可持续发展论为指导,以地理信息系统技术为研究手 段,对本区土地利用时空变化进行研究,并分析其驱动因子。林地的大幅度减少,耕地在近六 年锐减,而居民点及工矿用地、交通用地的大量增加。近十年的时间尺度,自然因素影响可以 忽略不计,可看成稳定的量。人口的增长、工业化和城镇化的加快是本区土地利用变化的重要 驱动因子,政治经济政策的制约、市场经济的引导,也是不可忽略的因子。

Jiuyuan district in Baotoucity was the suburb of baotou city, belong to the zone of farming-pasture ,country and city, the environment of the zone is weak. The land-use changed quickly in agriculture and construction. Based on the theories of systematology and sustainable development,this research probed into the time and spatial changes of land-use , and then analyze the driving forces. The forest has decreased greatly, the plough has decreased in six years. But the land of construction has increased greatly. The naturalfactor can be ignored because of only ten years. The most important factors are the growth of population , the rapid development quickly in industrialization and citilization. Secondly, politicaland economic policy and market economy are also of some factors.
