Then, using the change of index data, the entropy weight of each index was obtained and the composite weight of each index was determined by subjective weight and entropy weight. Finally, the sustainable development level of urban agriculture in the Changsha-Zhuzhou-Xiangtan urban agglomeration from 2010 to 2017 was evaluated and analyzed based on the TOPSIS model.[Results] ① During 2010-2017, the degree of urban agriculture sustainable development in the Changsha-Zhuzhou-Xiangtan urban agglomeration increased from 0.306 5 to 0.523 9. ② The sustainable development level trend for each sub-function was different, but it was on the rise overall.[Conclusion] The sustainable development level of urban agriculture in the Changsha-Zhuzhou-Xiangtan urban agglomeration fluctuated and increased from "low level" to "medium level". The economic function of urban agriculture gradually weakened and became marginalized. Increasingly more urban agriculture showed its social function, ecological function, and demonstration education function. To promote the sustainable development level of urban agriculture in the Changsha-Zhuzhou-Xiangtan urban agglomeration, it is necessary to maintain a certain amount of data and scale of the urban agricultural landscape land during the construction planning of the urban agglomeration, ensure the integrity of urban agricultural ecosystem structure, and increase the proportion of economic functions and develop each sub-function in a more coordinated way. %R 10.13961/j.cnki.stbctb.2019.05.039 %U http://stbctb.alljournal.com.cn/stbctb/home %1 JIS Version 3.0.0
