1990-2010年南阳市土地利用空间格局变化研究

Land Use Spatial Pattern Change of Nanyang During 1990-2010

选用河南省南阳市主城区1990、2000、2010年3个时期的遥感影像,结合数理统计的方法对该地区土地利用空间格局变化进行了分析。结果表明,南阳市土地利用类型以居民地、耕地和裸地为主,还有较大的开发潜力;南水北调中线工程的实施对该地区土地利用变化产生了重要的影响,使得大量耕地转向裸地和居民用地。

Taking Nanyang city as a case, based on the remote sensing images in 1990 〉2000 and 2010, this paper analysed the change of land use spatial pattern in Nanyang city by using the method of mathe-matical statistics. The results showed that residential land, cultivated land and bare land were the main land use types,and it has 纹 large exploration potentiality; The implementation of the Middle Route Project of the south to north water transfer had an important influence on the land use change in the region, so that made a large number of cultivated land to bare land and residential land.
