摘要 利用1988和2014年2期的Landsat TM/OIL遥感图像,应用监督分类的方法完成两期影像的土地利用类型的测量,并且基于GIS提取和统计土地利用变化信息,分析长春市经济开发区1988—2014年土地利用变化的时空特征。结果表明,旱地、水田、草地、林地、未利用土地、城镇、居民地等主要土地利用类型的面积均有不同程度的变化。结合社会经济统计资料分析该变化的原因,揭示了该地区土地利用变化的内在机制。 We used Landsat TM and OIL digital image to analyze the changing and features of land use from 1988 to 2104 in Changchun economic development zone,Jilin Province. Land use types were measured through the method of maximum likelihood classification. Land use change areas were determined and extracted by using post-classification comparison based on GIS. The result showed that the areas of the main land-use type such as farmland,paddy field,grassland,forest,unused land and built-up land had changed in different extent,which revealed that land use in study area had changed greatly during the study period. The expansion of urbanization was remarkable,and the article also revealed the internal mechanism of land use change based on the statistics data of social and economic.
