基于GIS-BPNN的喀斯特小流域土地利用变化模拟——以都安澄江小流域为例
Simulation of Land Use Change in Karst Minor Watershed Based on GIS-BPNN
摘要
Abstract
According to the historical data of Du' an County from 1988 to 2007, by using GIS technology and CA model, the standard three-BPNN was adopted to acquire all the space variable parameters of the model to simulate the land use /cover change of Duan Chengjiang watershed. As indicated by the results, in the watershed, the area of blalt land, farmland, especially unused and was expanding during 1999 -2015, the area of grassland and woodland was decreasing, the area of waters changed insignificantly.关键词
