Rapid industrialization and urbanization in China have led to a rapid increase in the number of brownfields, however there is a lack of identification of the spatial extent of brownfields in cities and accurate assessment of brownfield redevelopment. Based on the relationship between brownfields and urban complex ecosystems, this paper defines brownfields in China and constructs a comprehensive evaluation index system including socio-economic and ecological subsystems. Using Wuhu City as empirical evidence, 19 brownfields were identified using remote sensing data and field surveys. Based on the detection of soil contaminants in brownfields, a fuzzy integrated evaluation method was used to suggest their redevelopment direction. It is found that the government's planned land use types and the brownfield redevelopment evaluation results match to a large extent, but social, economic and ecological environmental factors should be more fully considered. At the same time, the identification and redevelopment of brownfield sites in the city as a whole need to be carried out by the government's professional forces in order to obtain more effective and scientific conclusions.
中国的快速工业化和城市化导致了棕地数量的迅速增加，但是缺乏对城市中棕地的空间范围的识别和对棕地再开发的准确评估。基于棕地与城市复杂生态系统的关系，本文定义了中国的棕地，并构建了一个包括社会经济和生态子系统的综合评价指标体系。利用芜湖市作为实证研究，使用遥感数据和实地调查识别了 19 个棕地。基于棕地土壤污染物的检测，采用模糊综合评价方法，提出了其再开发方向。研究发现，政府规划的土地利用类型与棕地再开发评价结果在很大程度上是一致的，但应更充分地考虑社会、经济和生态环境因素。同时，为了获得更有效和科学的结论，需要由政府的专业力量对城市整体的棕地场地进行识别和再开发。
