基于RS与GIS的山地城市建设用地扩展研究——以重庆市南岸区为例
Research on Mountainous Urban Construction Land Expansion Based on RS and GIS ——Taking Nanan District of Chongqing as an Example
摘要
Abstract
With continuously economic development and constant growth of global population,the shortage of construction land is more and more serious,and the research on mountainous urban construction land expansion plays an important role in further development of the cities.By using 8 periods Landsat-TM data during 1978-2010,through calculating landscape isolation,fractal dimension,dynamic degree,expansion index,barycenter and so on of construction land,quantitative research is conducted on construction land expansion process in Nanan District in 32 years,and the result indicates that construction land expansion in Nanan District keeps relatively high speed,that urban land-use structure is more compact,that construction land pattern is inclined to standardized development,that construction land stability is more and more strong and that its barycenter transfers toward southeast direction from west of Nanan District.This research result is of important reference significance to urban construction and planning of Nanan District.关键词
