摘要
利用地理信息系统技术,在空间数据库平台的支持下,对成都市20世纪90年代中期到2000年间的土地利用动态变化进行了研究。分析表明,在1995—2000年间,耕地与建设居民用地、耕地与林地、林地与草地以及水体与耕地等之间的转换强度较高。耕地减少10972 hm2,林地减少2220 hm2,草地增加8042 hm2,建设居民用地增加4830hm2,水体增加323hm2。减少耕地的主要去向是建设居民用地、草地和林地;减少林地的主要去向是草地。人口总数,第三产业从业人口,工业国内生产总值,第二、三产业的国内生产总值与建设居民用地同步增加;第一产业从业人员与耕地同步减少。
The land use dynamic change between 1995 and 2000 in Chengdu City was analyzed by using remote sensing and GIS here. The transfers took place mainly between cultivated land and construction residential land, cultivated land and forestland, forestland and grassland, waterbody and cultivated land in Chengdu City. The cultivated land decreased about 10972 hm^2. The forestland decreased about 2220 hm^2. The grassland increased about 8 042 hm^2. The construction residential land increased about 4 830 hm^2. The waterbody increased about 323 hm^2. The decreased cultivated land was changed into the construction residential land, grassland and forestland. The construction residential land as well as the total populations, the third possessions population, GDP for industry, GDP for the second possessions and the third possessions increased in meantime. The first possessions population as well as the cultivated land decreased in meantime.
