基于地学信息图谱的桂西南地区土地利用时空变化特征分析
Analysis of Spatial and Temporal Variation Characteristics of Land Use in Southwestern Guangxi Based on Geoscience Information Map
摘要
Abstract
Taking the southwestern region of Guangxi as an example,analyzing the spatiotemporal changes in land use based on geographic information technology can provide a basis for the rational utilization and protection of land resources in the region.Based on land use data from 2000 to 2020,the Geographic Information System(GIS)technology is applied to analyze the spatiotemporal evolution characteristics of land use in southwestern Guangxi from 2000 to 2020 using land use dynamics,transfer maps,and fluctuation maps.The land use type in southwestern Guangxi is mainly forest land,accounting for more than 55%of the total area,followed by arable land.Since 2000,the forest area in southwestern Guangxi has gradually decreased,while the construction land and water area have gradually expanded.There are temporal differences in the dynamic degree of grassland and arable land use,but the frequency of arable land area changes is relatively small.In the land use change pattern map,the unit with the largest land area is the stable map unit,and the proportion area of the previous change map is the smallest.In the fluctuation chart analysis,from 2000 to 2010,the area of cultivated land expanded the most(39.4%),and the area of forest land decreased the most(51.4%);from 2010 to 2020,the expansion of forest land area was the largest(37%);from 2010 to 2020,although the rate of reduction in forest land area was slow,it still accounted for the largest proportion,accounting for 43.16%of the total change area.关键词
