| 摘 要： | 根据珠江三角洲土地利用的实际情况,在借鉴国内外较为成熟的技术方法的基础上,利用Landsat卫星的TM和ETM 数据对珠江三角洲经济核心区域的土地利用进行了监督分类后的变化检测,探讨了该区域1998～2003年间的土地利用变化状况。另外,本研究以1998～2003年的土地利用变化为基础数据,着重探讨了各类土地利用转化的强度和趋势,同时分析其转化机理。结果表明,珠江三角洲经济核心区内城市逐步向外扩张,并侵占了其周边的农田用地,与此同时,为了保证农田总量的平衡,农田对其外围的林地逐步进行侵蚀,是林地总量减少的根本原因。本文通过对土地利用转化的机理研究,可以为政府土地管理部门进行农业结构调整、控制和规划提供重要的参考依据。

| Abstract: | According to the actual status of land use of Pearl River Delta(PRD),this research analyzed the land use change(1998-2003)of economic core corridor of Pearl River Delta based on TM and ETM data under the support of GIS tools using prevalent and mature technologies and methods.On the other side,this paper discussed inter-transform intensity and trend of each land use type in this core corridor of PRD specially.At the same time,this paper also analyzed the mechanism of land use change based on the classification data of 1998 and 2003.The results showed that:in past five years,urban had kept an even increasing current in economic core corridor of PRD,and with the increasing of urban;a lot of cropland had been occupied.In order to keep the quantity balance of cropland,a lot of forest around cropland was occupied quickly,and this has become an important reason that forest decreased.According to the results of this paper,it was valuable for government to control,adjust and plan the cropland land use policy. |
