新疆博州地区土地利用变化及驱动力分析

Analysis of Land Use/Cover Change and Driving Force on Bo Zhou of Xinjiang Province Zone

由于受自然因素与人文因素的影响,土地利用结构以及土地资源质量不断变化,从而引起区域生态环境和全球环境的变化。文章运用新疆博州2000-2009年土地利用数据,分析其土地利用的动态变化情况,发现耕地、居民点及工矿用地、交通用地、水利设施都有不同程度的增加,园地与牧草地的面积有所减少。接着运用博州社会经济发展状况有关数据和主成分分析法对博州地区面积变化的社会驱动力作定量分析,总结出农业结构的调整、经济发展、农业生产效益、政治经济政策这4个因素是引起博州土地利用变化的主要社会驱动力因子,且第一产业仍然处于主导地位。

The land use structure and the quality of land resource change constantly, because ot the natural factors and human factors, which results in the variation of the regional ecological environment and global environment. This article used the data of the land utilization in BoZhou of Xinjiang province from 2001 to 2009 to analyze its dynamic change. The conclusion is that farmland and land for household, industry, traffic and water conservancy facilities have increased in varying changes, while garden and grassland area have decreased. Afterwards, the social driving forces of the variation of land area in BoZhou were ana- lyzed quantitatively by analyzing the related data of social economy development, by the means of principal component analysis. We concluded that the adjustment of agricultural structure, economic development, production benefit, political and economic policies are main social driving forces causing variation of land u- tilization and the first industry is still in a dominant position.
