摘要
随着采矿业的发展，我国矿区土地资源破坏相当严重，同时废弃土地资源的复垦利用率又非常低（约１０％），矿区废弃土地复垦研究工作非常迫切。开展全国矿区废弃土地的适宜性评价研究是其复垦研究的基础，可为其它相关研究提供实时指导。本文正是根据这种需要，通过实地调查研究，运用一定的原则与依据，将矿区废弃土地资源划分为５类２５个亚类，均对每一亚类，作出了相应的适宜性评价，同时还提出了具体的开发利用途径。为矿区废弃土地复垦在技术上的可行性作出了科学的评价，为废弃土地资源的复垦提出有效的开发利用途径，从而为提高土地生产力，缓解土地资源紧缺的矛盾，改善矿区生态环境质量提供有效的政策与技术参考。
It is urgent in the time of high speed development of China's mining industry to research the issue of waste land reclamation of China's mining areas because of the severe damage of China's land resources in mining areas and low reclamation ratio (about 10%) of its waste lands. To launch in the whole country the suitability assessment of the waste land reclamation of China's mining areas can serve as a real time guide for relevant researches because of its basic function in the research of the waste land reclamation of China's mining areas. According to this function, the thesis divides the waste land resources of China's mining areas into 25 sub categories of 5 categories on the basis of field investigation and utilization of certain principles. Every type of 25 sub categories is assessed on their suitability for the waste land reclamation, and corresponding ways for the exploitation and utilization of China's waste land resources are also put forward. These detailed methods can in an efficient way serve as a scientific assessment tool for the evaluation of China's waste land reclamation, so as to improve the efficiency of China's waste land reclamation and utilization, and to provide an efficacious reference for relevant policy making.
