基于GIS-Logistic回归模型的土地利用变化及驱动机制研究

Land use change and driving mechanism based on GIS-Logistic regression model

土地利用/覆被变化(Land Use/Land Cover Change,LUCC)能够客观地反映地区生态环境变化,从而为优化土地利用,推进城市可持续发展提供参考。本文以武汉市为研究区,采用气象环境数据、社会经济数据等多源多时相监测数据,运用GIS-Logistic耦合模型分析LUCC的驱动机制。结果表明,在高度城镇化的地区,政策的实施可能是其他土地利用类型转化为城镇及工矿用地的主要驱动因素。

Land Use/Land Cover Change(LUCC)can objectively reflect changes in the regional ecological environment and provide a reference for land use optimization and sustainable urban development.This paper took Wuhan as the research area,adopted multi-source and multi-temporal monitoring data such as meteorological environmental data,socio-economic data,and used GIS-Logistic coupling model to analyze the driving mechanism of LUCC.The results showed that in highly urbanized areas,the implementation of policies may be the main driving factor for the conversion of other types of land use into urban and industrial and mining land.
