富宁县2000~2018年土地利用变化及影响因素分析

Analysis of Land Use Change and Influencing Factors in Funing County from 2000 to 2018

根据云南省富宁县2000年、2005年、2010年、2015年及2018年的遥感土地利用分类图,计算了富宁县单一土地利用动态度、土地利用变化幅度以及土地利用转移矩阵,以此分析富宁县的土地利用变化状况。结果表明2000~2018年富宁县土地利用类型以林地、草地和耕地为主;林地和草地面积不断缩小,水域和城乡、工矿、居民用地持续增长;土地利用之间的转化主要发生在草地、林地、耕地和水域这四种土地利用类型,同时结合富宁县的实际状况剖析得出,人口、经济、政策以及城镇化是影响其土地利用变化的主要因素。

According to the remote sensing land use classification map of Funing County, Yunnan Province in 2000, 2005, 2010, 2015 and 2018. This paper calculates the dynamic degree of single land use, the range of land use change and the land use transition matrix in Funing County. On this basis, analyzed the land use change in Funing County. The results showed that the main land use types in Funing County from 2000 to 2018 are woodland, grassland and cultivated land. The area of forest land and grassland keeps shrinking, while the water area, urban and rural areas, industrial and mining land and residential land keep increasing. The conversion of land use mainly occurred in four land use types: grassland, forest land, cultivated land and water area. Combined with the analysis of the actual situation of Funing County, it can be concluded that population, economy, policy and urbanization are the factors affecting the change of land use.
