摘要
利用多源遥感卫星数据,对江宁3个不同时期的土地利用现状进行解译得到了土地利用类型图,借助地理信息系统空间数据叠置功能以马尔柯夫概率模型的类型转移矩阵对江宁土地利用/覆盖变化进行了分析。结果表明,在近20年的时间里,由于经济的快速发展使城市化水平提高,导致辽宁耕地损失达4214.02hm2这些耕地被转化为城市基础设施建设用地和经济效益较高的养殖业,但人地矛盾日渐突出。
With multi-source remote sending satellite data the land use coverage＇s has been obtained from the tree-periods present land use in Nanning. Based on this, the spatial data overplay analysis with the aid of GIS software and a type transition matrix of Markov Chain Model is worked out to analyze the land use/cover change in Nanning. The results indicate that in the recent twenty years, cultivated land has been loss 4214.02 Hectare with the advanced urbanization caused by the economy development. And these cultivated lands have been converted into the urban infrastructure built-up land and aquaculture land with high economic benefit, but the contradiction between human and land is still intensified gradually.
