Comprehensive Evaluation of Sustainable Development of Urban Agriculture in Changsha-Zhuzhou-Xiangtan Urban Agglomeration
[Objective] Based on the evaluation of sustainable development of urban agriculture in China and abroad
and considering the multi-function of urban agriculture
an evaluation index system for the sustainable development of urban agriculture was constructed to evaluate the sustainable development of urban agriculture in Changsha-Zhuzhou-Xiangtan urban agglomeration and provide theoretical support for the construction of an urban agglomeration.[Methods] First
the subjective weight of each index was determined using the analytic hierarchy process. 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.
