摘　　要：基于GIS平台定量、定性分析研究区内长时间序列土地利用类型变化,了解土地利用空间分布,构建土地利用多特征功能性指数等,联合分析土地利用时空演变特征,进行土地利用演变驱动力分析。分析发现:研究区2000—2020耕地面积总体减少,向建设用地转移,建设用地呈快速增加状态;土地利用向多样化方向发展,土地利用程度增强,绝大部分区域呈快速发展状态。而经济结构改变及社会变革正是推动研究区内土地利用变化的主要驱动因素。研究成果可作为该区域土地利用可持续发展提供科学依据、数据支撑。Based on GIS platform,quantitative and qualitative analysis of long-term series land use type changes in the study area,understanding the spatial distribution of land use,constructing a land use multi-feature functional index,etc.,jointly analyzing the spatiotemporal evolution characteristics of land use,and conducting a driving force analysis of land use evolution.Analysis shows that from 2000 to 2020,the overall cultivated land area in the research area has decreased and shifted towards construction land,resulting in a rapid increase in construction land;Land use is developing towards diversification,and the degree of land use is increasing.The vast majority of regions are in a state of rapid development.The changes in economic structure and social transformation are the main driving factors for promoting land use change in the research area.The research results can provide scientific basis and data support for the sustainable development of land use in the region.
