摘要:分析土地利用功能演变及生态环境响应是区域"三生空间"划定和管控以及生态环境保护的重要依据。以桂西资源富集区为例，基于1995年、2000年、2005年、2010年和2015年5期遥感数据，构建"三生空间"土地利用主导功能分类体系，运用转移矩阵、重心转移和生态环境响应模型分析研究区20年土地利用功能演变特征及生态环境响应情况，结果表明：（1）研究区生态生产空间和生活生产空间面积呈上升趋势，生产生态空间和生态空间面积呈下降趋势。（2）生态生产空间重心转移距离最大，其次是生活生产空间重心，生产生态空间和生态空间重心转移距离较小。（3）研究区生态环境质量指数从1995年的0.6337持续降至2015年的0.6323，整体质量有所下降。（4）以林草地为主要地类的县域生态环境质量较高，重点矿产资源型县域和农产品生产基地生态环境质量较低，城镇化重点县域生态环境质量最低。



Abstract:Analysis of the transformation of land use function and ecological environment response is a fundamental basis for the delineation and control of regional "production-life-ecology space" and ecological environment protection. Based on the remote sensing data in 1995, 2000, 2005, 2010 and 2015, we constructed a land use classification system of "production-life-ecology space" in the resource-abundant area in western Guangxi. Using transfer matrix, center of gravity transferring and ecological environment response model, the paper has analyzed the transformation characteristics of land use function and response of eco-environment in the study area in the past two decades. The results showed that: (1) the areas of ecological production space and life space of the research area were rising, while the production of ecological space and ecological space were declining. (2) The transfer distance of the center of gravity of ecological production space was the largest, followed by the center of gravity of life production space, and the transfer distance between the center of gravity of production ecological space and the center of gravity of ecological space was relatively small. (3) The ecological and environmental quality index of the research area decreased from 0.6337 in 1995 to 0.6323 in 2015, and the overall quality declined. (4) The urban ecological environment exhibited higher quality, while the critical mineral resource county and the agricultural production base presented lower quality, and the quality of ecological environment in key urbanization counties was the lowest.
