汉江流域在我国区域生态安全和经济社会发展格局中的战略地位日益凸显，开展三生空间用转型及其生态环境效应研究能为该区生态文明建设和国土空间规划提供参考。基于 1990-2020年土地利用/覆盖数据和"生产—生活—生态"(三生空间)视角，运用转移矩阵、生态贡献率等研究方法，分析了汉江流域三生空间用地转型及其生态环境效应的时空演变特征。结果表明:1990-2020年汉江流域以生态空间为主，生态空间面积先减后增且集中分布在丹江口以上流域，生产空间由增转减，生活空间始终处于增加态势;1990-2020年汉江流域三生空间类型转移关系保持稳定，以生态空间和生产空间的互转为主，转移规模呈先减后增趋势;汉江流域生态环境质量呈西高东低空间格局，高质量区面积持续增加，其他质量区不同程度下降;影响汉江流域生态环境改善、恶化的主导用地类型分别为生产空间转化为林地绿色和蓝色生态空间，草地及林地绿色、蓝色生态空间转化为生产空间。
Spatial transformation pattern of ecological-production-living spaces and its eco-environmental effects in Hanjiang River Basin
The Hanjiang River Basin plays an increasingly prominent strategic position in the pattern of regional ecological security and economic and social development in China.The study on the transformation of three life spaces and its ecological environmental effect can provide a reference for the construction of ecological civilization and territorial spatial planning in this area.Based on the land use/cover data from 1990 to 2020 and the perspective of"production-life-ecology",this paper analyzes the spatial and temporal evolution of land use transformation and its ecological environmental effects in the Hanjiang River Basin by using the transfer matrix and ecological contribution rate.The results showed that from 1990 to 2020,the Han River basin was dominated by ecological space,the ecological space area decreased first and then increased,and the ecological space was concentrated in the basin above Danjiangkou.The production space changes from increasing to decreasing,and the living space is always increasing.The transfer relationship of the 3 species space type in the Hanjiang River Basin remained stable,mainly the mutual transfer of ecological space and production space,and the transfer scale showed a trend of decreasing at first and then increasing.The ecological environment quality of the Hanjiang River Basin showed a spatial pattern of higher in the west and lower in the east.The area of the high-quality area continued to increase,while the area of other quality areas decreased to different degrees.The main land types affecting the improvement and deterioration of the ecological environment in the Hanjiang River Basin were the conversion of production space into forest green and blue ecological space,and the conversion of grassland and forest green and blue ecological space into production space.
