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.
