摘要
以重庆市九龙坡区为例,运用GIS的空间提取与分析功能,对多时相遥感影像的城镇建设用地进行提取,并通过象限方位法与城镇扩张强度指数,对城镇建设用地扩张的方向及特征进行定量与定性分析,研究结果表明城镇建设用地的扩张具有明显的政策引导及方向性,新型城镇建设应坚持"增存并重",全面优化空间布局。
Taking Jiulongpo District of Chongqing as an example,using the spatial extraction and analysis function of GIS,the urban construction land of multi temporal remote sensing image is extracted, and the direction and characteristics of urban construction land expansion are quantitatively and qualitatively analyzed by quadrant orientation method and urban expansion intensity index. The research results show that the expansion of urban construction land has obvious policy guidance and direction,and the new urban construction should adhere to the principle of "increase and save equally",and comprehensively optimize the spatial layout.
