摘要
以2000年、2010年、2020年30 m分辨率土地利用数据为基础,采用变化量和年变化量方法,分析了贵州省2000-2020年土地利用变化特征.结果表明:(1)贵州省土地利用以林地、耕地和草地为主,灌木地、湿地、水体和人造地表面积比例较低;(2)2000-2020年贵州省草地和林地减少面积最大且减少速度最快,人造地表增加面积最大且增加速度最快;(3)2000-2020年贵州省土地利用转移主要表现为耕地、林地和草地之间的相互转移与耕地向人造地表的转移.
Abstract
Based on 30m-resolution land use data in 2000,2010 and 2020,this paper uses change and annual change methods to analyze the characteristics of land use changes in Guizhou Province from 2000 to 2020.The re-sults are as follows.(1)Land use in Guizhou Province was mainly dominated by forest land,cultivated land and grassland,with a lower area proportion of shrubland,the wetland,the water body and the artificial surface.(2)From 2000 to 2020,the area of grassland and forest land in Guizhou Province decreased the largest and fastest,and the area of the artificial land surface increased the most and the fastest.(3)From 2000 to 2020,land use transfer in Gui-zhou Province was mainly manifested in the mutual transfer among cultivated land,forest land and grassland,as well as the transfer of cultivated land to the artificial land surface.
