满洲里市土地利用动态变化及其驱动力分析

Research on Dynamic Variation of the Land Use and Its Driving Force in Manzhouli City

满洲里市是我国最大的内陆边境口岸城市,随着边境贸易的发展,土地利用类型也随之发生变化。本文采用土地利用动态度、土地利用结构信息熵,以及灰色关联分析方法对该区域土地利用变化及其驱动机制进行了分析。结果表明:满洲里市的土地利用数量变化主要表现为居民点及工矿用地和交通运输用地对牧草地的占用;土地利用结构信息熵和均衡度呈现增长趋势,土地利用结构趋于均质性化发展;近10年来,满洲里市的土地利用变化主要受到旅游业和口岸经济的影响。

Manzhouli city is the largest inland border city of our country. With the development of border trade, great changes have taken place in the land use type in Manzhouli city. The article analyzed land use change and its driving mechanism by using the methods of dynamic degree and the in-formation entropy of land use structure method and grey correlation analysis. The results showed that the land use quantity change mainly for residential areas and mining land and transportation land to grassland utilization, the land use structure information entropy and equilibrium degree showed an increasing trend and the land use structure tend to homogeneity development. In recent 10 years, the land use change of Manzhouli city is mainly affected by the economy of tourism and port.
