以湖北省恩施州为例,构建“三生空间”功能分类体系,使用土地利用转移矩阵、重心转移模型、生态环境质量指数模型和生态贡献率模型研究“三生空间”功能演变及其对生态环境的响应。结果表明,2000—2020年,生活空间面积整体呈上升趋势,生态空间面积整体呈下降趋势,生产空间面积呈先下降后上升的趋势;生活空间转移距离最大,其次是生产空间,生态空间转移距离最小;生态环境质量整体呈下降趋势;农业生产用地转为重点生态用地和一般生态用地、一般生态用地转为重点生态用地是生态环境质量改善的主要因素,重点生态用地转为农业生产用地和一般生态用地是生态环境质量下降的主要因素。

Taking Enshi Prefecture of Hubei Province as an example,a functional classification system of"productive-living-ecologi-cal space"was constructed,and the functional evolution of"productive-living-ecological space"and its response to the ecological en-vironment was studied using the land use transfer matrix,center of gravity shift model,ecological environmental quality index model and ecological contribution ratio model.The results showed that,from 2000 to 2020,the overall trend of living space area was on the rise,the overall trend of ecological space area was decreasing,and the area of produc...
