摘要
探究高分卫星在城市土地利用类型分析中的应用,为区域土地资源合理规划和可持续利用提供科学依据,以保定为研究区域,基于2021、2023、2025年国产GF系列卫星遥感影像,对研究区土地利用变化特征进行分析。结果表明:保定土地利用类型分布集中,裸地面积最大;与2021年相比,2025年保定建设用地、耕地面积减少,裸地面积增加,林地、水体面积总体呈增加趋势但有所波动,反映出土地利用结构及变化受政策导向、地貌、气象要素、人类活动等多种因素的影响。
To explore the application of GF satellite in analyzing urban land use types and to provide a scientific basis for the planning and sustainable utilization of land resources,the characteristics of land use changes in Baoding were analyzed based on the remote sensing images of GF satellite from 2021,2023,and 2025.The results indicate that the distribution of land use types in Baoding is relatively concentrated,with the largest area of bare land.Compared with 2021,the area of construction land and cultivated land decreased in 2025,while the area of bare land increased.The area of forest land and water generally increased with a small range of fluctuation.This reflects that the structure and changes of land use are affected by multiple factors such as policy orientation,landforms,meteorological elements,and human activities.
