1980-2017年吉林省土地利用变化及驱动力分析

全球变化影响不断深入,土地利用变化成为重要问题之一。对吉林省1980-2017年的土地利用的变化幅度、动态变化度以及运用ArcGIS计算土地利用的转移矩阵,揭示了吉林省近40年土地利用整体、分区的变化特征及规律,1980年土地利用面积:林地>耕地>草地>未利用土地>城乡工矿居民地>水域;2017年土地利用面积:林地>耕地>未利用土地>草地>城乡工矿居民用地>水域,土地利用类型转化以耕地、未利用土地为主。采用相关分析法对社会经济因素进行分析,经济因子、技术因子是土地变化的主要因子。研究为吉林省土地资源调节、生态环境保护、总体发展提供依据。

Analysis of land use change and driving force in Jilin Province from 1980 to 2017

With the impact of global change deepening,land use change has become one of the most important issues.Based on the land use data of Jilin Province from 1980 to 2017,the change range,dynamic change degree and the transfer matrix of land use calculated by ArcGIS,the change characteristics and rules of land use in Jilin Province in the past 40 years are revealed.Land use area in 1980:woodland>cultivated land>grassland>unused land>urban and rural industrial and mining residential land>water area;land use area in 2017:woodland>cultivated land>unused land>grassland>urban and rural industrial and mining residential land>water area.The transformation of land use types is mainly cultivated land and unused land.Using correlation analysis method to analyze social and economic factors,economic factors and technology factors are the main factors of land change.The study provides a basis for land resources regulation,ecological environment protection and overall development in Jilin Province.
