【摘要】：矿区土地治理与再利用是一项紧迫的任务,由于多年的矿产开采,导致矿区的大面积土地破坏和废弃,土壤及地下水污染,从而形成了矿区棕地并造成大量的土地价值损失,加剧了矿区的人地矛盾。因此,研究棕地这一类特殊土地的再利用对于矿区的可持续发展具有重要的现实意义。通过分析国内外矿区棕地研究相关理论与方法,结合我国矿区棕地的现状,探讨了矿区棕地综合治理的方案和措施。建议我国矿区棕地治理和再利用方案框架可划分为调查评价、生态修复和土地复垦与景观再造3个阶段:调查评价阶段主要包括棕地土壤环境质量评价与可持续利用评价;生态修复阶段可选择适宜的技术方法进行污染土壤和地下水修复;土地复垦与景观再造阶段是根据矿区棕地类型及分布特点,因地制宜,进行棕地复垦和综合治理利用。同时讨论了每个阶段的主要工作内容和措施,比较了不同修复技术方法的优劣,给出了我国矿区棕地复垦和综合利用的模式建议。
[Abstract]:It is an urgent task to control and reuse the land in the mining area. Because of the mining for many years, the large area of land in the mining area is destroyed and abandoned, and the soil and groundwater are polluted, thus forming the brown land in the mining area and causing a great deal of loss of land value. The contradiction between man and land in the mining area has been aggravated. Therefore, it is of great practical significance to study the reuse of brown land as a special land for the sustainable development of mining area. By analyzing the relevant theories and methods of mining brown land research at home and abroad, combined with the present situation of mining brown land in China, this paper probes into the plans and measures for comprehensive control of mining brown land. It is suggested that the scheme framework of brown land management and reuse in mining areas in China can be divided into three stages: investigation and evaluation, ecological restoration, land reclamation and landscape reconstruction: the investigation and evaluation stage mainly includes evaluation of soil environmental quality and sustainable utilization of brown land; In the stage of ecological restoration, suitable technical methods can be selected for the remediation of contaminated soil and groundwater, and the stage of land reclamation and landscape reconstruction is to carry out reclamation and comprehensive utilization of brown land according to the types and distribution characteristics of brown land in mining areas. At the same time, the main work contents and measures of each stage are discussed, and the advantages and disadvantages of different restoration techniques are compared, and suggestions on the mode of reclamation and comprehensive utilization of brown land in mining areas in China are given.
