摘要
选取库尔勒市城区为研究区,以2009、2012、2014年Rapid Eye影像为数据源,利用混合像元分解方法提取了库尔勒市的不透水面信息,分析了不透水面的时空变化特征。选取高程、坡度、坡向、距水系距离、距道路距离、距2009年城区距离、距规划区距离7个因子,利用Logistic回归进一步分析了2009—2014年库尔市不透水面扩张的主要影响因素。结果表明:2009年库尔勒市不透水面所占比例为27.04%,2012年为32.89%,2014年为35.69%;各因素的贡献率依次为坡度、坡向、距规划区距离、距道路距离、距2009年城区距离、距水系距离、高程;整体来看,在交通线密集的地方,城市不透水面分布较多,相对而言交通线稀疏的地方不透水面分布较少,并且具有沿道路轴线发展的趋势。
The paper analyzes the impervious surface information of Korla City in 2009,2012 and 2014 by using the method of mixed pixel decomposition,and analyzes the temporal and spatial characteristics of impervious surface. It is selected seven factors such as elevation,slope,aspect,distance from the water system,distance from the road,distance from 2009 city boundary,distance from the planning area to analysis the reasons of the expansion further under Logistic regression. Results shows that： the proportion of water-impermeable surface in Korla City in 2009 is 27. 04%,32. 89% in 2012 and 35. 69% in 2014; The contribution rate of each factor is slope,slope,distance from the planning area,distance from the city in 2009,distance from the water,elevation; On the whole,in the traffic-intensive areas,the city is not more water distribution,relatively speaking,the sparse areas of the traffic line is less water distribution and has a trend along the road axis.
