近30年中国矿业废弃地生态修复及再利用研究热点及趋势分析

随着社会经济的发展与工业化进程的推进,矿山开采带来巨大经济效益的同时,遗留众多难以利用的矿业废弃地,如何对其进行生态修复与再利用成为学者的研究热点。基于CiteSpace计量分析软件梳理近30年中国矿业废弃地生态修复及再利用研究文献共4 448篇,根据时间尺度分为缓慢发展阶段（1990-2000年）、快速增长阶段（2001-2010年）、平稳递增阶段（2011-2020年）三个阶段,依据不同时期的高频关键词初步把握近30年国内矿业废弃地生态修复与再利用领域研究热点,主要围绕土地复垦、生态修复、矿山公园、生态补偿等方面,实现从自然生态视角到生态经济目标、从单一土地复垦到系统生态修复、从传统修复方法到高新技术应用等方面的转变,回顾由单维度过渡到多维度的研究内容。在后续研究中需着重加强理论系统研究、多学科融合与交叉、综合效益评价、公众感知参与等方面,促进矿业废弃地生态修复与再利用理论与实践研究逐渐达到“人”“地”和谐统一的发展目标。

Analysis of Research Hotspots and Trends in Ecological Restoration and Reuse of China

With the development of society and economy and the advancement of industrialization, mining has brought huge economic benefits, while many unusable mining wastelands are left. How to restore and reuse them has become a research hotspot of scholars. A total of 4 448 papers on ecological restoration and reuse of China"s mining wastelands in the past 30 years were sorted out based on CiteSpace measurement analysis software. According to the time scale, it can be divided into three stages: slow development stage (1990-2000), rapid growth stage (2001-2010) and steady growth stage (2011-2020).Based on high-frequency keywords in different periods, the research hotspots in the field of ecological restoration and reuse of mining wastelands in China in the past 30 years were preliminarily grasped, mainly around land reclamation, ecological restoration, mine park, ecological compensation and so on.Realize the transition from natural ecological perspective to ecological economic goals, from single land reclamation to systematic ecological restoration, from traditional restoration methods to high-tech applications, and review the transition from single-dimensional to multi-dimensional research content. In the follow-up research, it is necessary to focus on strengthening theoretical system research, multi-disciplinary integration and intersection, comprehensive benefit evaluation, public perception participation, etc., to promote the theoretical and practical research on ecological restoration and reuse of mining wasteland to gradually achieve the harmonious unity of "people" and "land" development goals.
