中文摘要：在构建"三生空间"用地类型划分体系的基础上综合运用土地用地转移矩阵、生态环境质量指数及土地利用转型生态贡献率等方法，定量分析2000-2020年长株潭都市圈"三生空间"用地的转型特征及其生态环境效应。结果表明，2000-2020年，长株潭都市圈"三生空间"用地中生态用地为主要用地类型，生活用地和生产用地数量动态变化幅度大;从"三生空间"用地转型结构来看，以农业生产用地和林地生态用地的相互转化为主导，同时农业生产用地和林地生态用地大量转为工矿生产用地和城镇生活用地;长株潭都市圈生态环境质量总体呈逐渐减缓的下降趋势，其中2005-2010年恶化程度最突出，研究期内低质量区和较低质量区不断扩张;影响生态环境改变的主导因素是农业生产用地和林地生态用地的相互转换以及城镇生活用地和工矿生产用地的对外扩展侵占了大量的林地生态用地。

外文标题：Land use transformation and ecological environment effects of"production-living-ecological spaces"in Changsha-Zhuzhou-Xiangtan Metropolitan Area

外文摘要：Based on the construction of the land type division system of"production-living-ecological spaces",comprehensively using the methods of land transfer matrix,ecological environment quality index and ecological contribution rate of land use transformation,the characteristics and ecological environmental effects of"production-living-ecological spaces"land transformation in Changsha-Zhuzhou-Xiangtan Metropolitan Area were quantitatively analyzed from 2000 to 2020.The results showed that from 2000 to 2020,the ecological land was the main land type in the"production-living-ecological spaces"land in Changsha-Zhuzhou-Xiangtan Metropoli-tan Area,and the dynamic changes of the quantity of living land and production land were large;from the perspective of the"produc-tion-living-ecological spaces"land use transformation structure,the agricultural production land and forest land ecological land were mainly transformed into each other,and a large number of agricultural production land and forest land ecological land were trans-formed into industrial and mining production land and urban living land;the ecological environment quality of the Changsha-Zhu-zhou-Xiangtan Metropolitan Area showed a gradual decline trend,and the deterioration was the most prominent from 2005 to 2010.During the study period,low-quality areas and lower quality areas continued to expand;the main factors affecting the change of eco-logical environment were the conversion of agricultural production land and forest ecological land and the external expansion of urban living land and industrial and mining production land,which occupied a large amount of forest ecological land.
