摘要
以GIS空间分析技术和景观生态学理论为支撑,探究2015—2020年丹江口核心水源区(湖北段)三生空间(生态空间、生产空间、生活空间)用地功能转型与景观格局的时空演变特征。结果表明:(1)2015—2020年期间,生态和生产用地下降,生活用地增加,生态和生产空间的互转以及两者向生活空间的转移是主要趋势;(2)流域内不同县(区)三生空间变化幅度存在差异,但普遍存在耕地、林地和草地减少、城乡和交通用地增加的趋势;(3)流域人工地表景观格局指数优于自然地表。基于“三生空间”功能视角研究土地利用转型及其景观格局效应,可为丹江口核心水源区(湖北段)国土空间开发与保护格局的协调发展提供借鉴价值。
Based on GIS spatial analysis technology and landscape ecology theory,this paper explores the spatio-temporal evolution characteristics of the land use function transformation and landscape pattern of the production,living,and ecological space in Danjiangkou core water source area(Hubei section)from 2015 to 2020.The results show that:①During 2015-2020,the ecological and production land decreased,the living land increased,the ecological and production space and the transfer of the two to the living space were the main trends.@There are differences in the change range of production,living and ecological space in different counties(districts)in the watershed,but there is a general trend of decreasing cultivated land,forest land and grassland,and increasing urban and rural land and traffic land.③The landscape pattern index of artificial surface is better than that of natural surface.The study of land use transformation and its landscape pattern effect based on the functional perspective of production,living and ecological space can provide reference value for the coordinated development of land space development and protection pattern in Danjiangkou core water source area(Hubei section).
