人们普遍认为，布朗菲尔德再生为绿色空间是一种可持续的城市发展形式。然而，选择那些最有潜力融入城市绿色基础设施（GI）的棕地至关重要。本文讨论了如何定量评估城市层面的煤炭开采棕地的生态潜力，并着眼于这些棕地如何能够最好地适应，以提高GI系统。以徐州市为例，综合考虑布朗菲尔德更新为绿色空间的生态重要性和维持地理信息系统连通性的能力，建立了该区域的生态潜力评价方法。结果表明，超过一半的煤矿棕地具有相对较高的生态重要性值，只有4个斑块在维持生态系统连通性方面起重要作用。将生态重要性值与维持GI连通性的容量值叠加，得到最终的布朗菲尔德更新为绿色空间的生态潜力值。然后，根据棕地的生态潜力值将棕地分为五个组，各组的生态潜力值差异显着。约51.35%的棕地具有高或非常高的恢复GI潜力，分布在西部矿区的东南部和东部矿区的中部。该方法可为围海造地科学家和城市规划者提供定量分析的决策依据。
It is widely recognized that brownfield regeneration to green space is a sustainable form of urban development. However, it is essential to choose those brownfields that have the greatest potential to be integrated into urban green infrastructure (GI). This paper addresses how to quantitatively assess the ecological potential of coal mining brownfields at the city level, and looks at how these brownfields can be best adapted to enhance the GI system. Taking Xuzhou as an example, an ecological potential assessment method for brownfield regeneration to green space is established considering both its ecological importance and the capacity of maintaining GI connectivity. The results show that more than half of the coal mining brownfields have relatively higher ecological importance values, and only four patches play an important role in maintaining GI connectivity. The final ecological potential values of brownfield regeneration to green space are obtained by overlaying the values of ecological importance and the capacity values of maintaining GI connectivity. Then, all the brownfields are divided into five groups according to their ecological potential values, which are significantly different in each group. Around 51.35% of the brownfields have a high or very high potential for restoration to GI, which are distributed in the southeastern part of the western mining area and the central part of the eastern mining area. The presented method can assist reclamation scientists and urban planners in decision making based on quantitative analysis.
