摘要
国土空间生态修复关键区的识别是锚固城市生态安全底线的关键,矿业废弃地作为众多资源型城市生态修复的核心内容,分区建设具有重要现实意义.本研究基于生态功能与空间的重要性对邯郸市的矿业废弃地进行评级分区,以此为城市生态修复工作的有序开展提供一定的理论支撑.研究框架方面,提出在城市尺度下基于功能层面的生态保护重要性与空间层面的生态安全格局叠加,以得到更准确的生态修复关键区识别结果.研究过程中,选择契合地域特征的水源涵养、土壤保持、生物多样性维护和水土流失敏感性4项指标进行生态保护重要性评价,选择MSPA-Conefor-SPCA-MCR-电路理论进行生态安全格局构建.结果表明:邯郸市剩余的204处矿业废弃地中,有73处属于生态修复关键区,总面积为1500.9 hm2,主要集中于鼓山、凤凰山及符山区域.这些区域虽存在严重的生态环境问题,但同样赋存着巨大的潜力价值.在简单覆绿的基础上积极寻求场地转型、延长矿山生态修复治理的价值链和产业链或许将成为这些区域的更重要目标.
Abstract
The identification of key areas for ecological restoration in national land space is crucial for anchoring the bottom line of urban ecological security.As the core of ecological restoration in many resource-based cities,the zoning construction of abandoned mining sites has practical significance.We classified the abandoned mining sites in Handan City based on ecological functions and spatial importance,aiming to provide theoretical support for the orderly development of urban ecological restoration work.In terms of research framework,we proposed to overlay the importance of ecological protection at the functional level and the ecological security pattern at the spatial level,in order to obtain more accurate identification results of key ecological restoration areas at the urban scale.During the study process,we selected four indicators that fitting the regional characteristics of water conservation,soil con-servation,biodiversity conservation,and soil erosion sensitivity for ecological protection importance evaluation,and selected the MSPA-Conefor-SPCA-MCR-circuit theory to construct the ecological security pattern.The results showed that 73 out of the remaining 204 abandoned mining sites belonged to the key ecological restoration areas,with a total area of 1500.9 hm2 in Handan City,which were mainly concentrated in the regions of Gushan,Feng-huangshan,and Fushan mountains.These regions had serious ecological and enviornmental problems,but with enormous potential value.Actively seeking site transformation on the basis of simple greening to extend the value chain and industrial chain of mining ecological restoration may become a more important goal in these regions.
