Abstract: 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 Metropolitan Area, and the dynamic changes of the quantity of living land and production land were large; from the perspective of the “production-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 transformed into industrial and mining production land and urban living land; the ecological environment quality of the Changsha-Zhuzhou-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 ecological 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.

Key words: land use transformation of “production-living-ecological spaces”, ecological environment effects, ecological contribution rate, Changsha-Zhuzhou-Xiangtan Metropolitan Area
