摘要:

基于1985~2015年的杭州市遥感卫星影像数据,使用ArcGIS和ENVI提取土地利用类型信息.使用土地利用类型面积比例、土地利用动态度、土地利用转移矩阵以及耕建系数,对杭州市的土地利用情况进行定量分析.结果表明:1)建设用地逐年递增,耕地逐年递减,水体和林地波动较小.2)建设用地总量和转变程度逐年递增,主要来源是耕地;耕地总量和转变程度逐年递减,主要来源为林地和建设用地;林地和水体的主要转变来源和去向都是耕地.3)八区土地城市化进程存在时序差异,耕建系数可以较好地反映土地城市化进程.4)上城区、下城区和拱墅区处于均衡阶段,江干区、滨江区和西湖区处于趋稳阶段,萧山区和余杭区处于转变阶段.

Abstract:

The information of land use type was extracted with the help of ArcGIS and ENVI software based on the remote sensing satellite image data of Hangzhou city in 1985-2015. Ratio of land use type, land use dynamic degree, land use transfer matrix and cultivated-construction land coefficient were used for quantitative determination of land use in Hangzhou city. 1) The construction land progressively increases year by year, while the cultivated land decreases, and the water body and forest land are less volatile.2) Construction land and its transition degree increase, main source is cultivated land. Cultivated land and its transition degree decrease, main source is forest land and construction land. The main source and direction of forest land and water body are construction land. 3) The process of land urbanization in eight districts has a time-series distinction, which can be well reflected by the cultivated-construction land coefficient. 4) Shangcheng, Xiacheng and Gongshu District are in the equilibrium stage. Jianggan, Binjiang and Xihu District are in the stabilization stage. Xiaoshan and Yuhang District are in the transition stage.
