摘要
【目的】梳理煤矿区土地复垦取得的理论技术成果,为开展煤矿区土地复垦工作提供参考。【方法】在CNKI中检索煤矿复垦相关文献,对检索到的1 406篇相关文献按时间段分类统计,通过总结、归纳和提炼得出煤矿区土地复垦研究现状与前沿。【结果】煤矿区土地复垦研究主要集中在煤矿区土地复垦方向、复垦技术、复垦模式等3方面。煤矿区土地复垦方向的确定集中于适宜性评价上,评价单元划分、评价体系构建、权重确定、评价方法选取等方面是其中的研究重点;土地复垦技术不断创新,形成了以地貌重塑、土壤重构、植被恢复为主的技术体系;土地复垦模式多样,并由单一模式向综合模式发展。【结论】煤矿区土地复垦虽取得重大成果但仍存在复垦的土地质量差,复垦利用率低,恢复和保护生态环境的作用不能有效发挥等问题,复垦方向确定的科学化、复垦技术生态化、复垦模式综合化将是今后煤矿区土地复垦的研究重点。
[Purposes]It provides a reference for land reclamation work in coal mining area by combing its land reclamation theory and technology.[Methods]By the way of summarizing,summing up and refining the research of present situation and the future through the retrieve of related 1,406 papers according to the time classification in CNKI relevant literature.[Findings]The research mainly concentrated on land reclamation direction which determines the direction of land reclamation in coal mine area focused on the evanluation of suitability,unit division and system to build,such as weight,evaluation method of selection is the key research;Land reclamation technology innovation,form,reclamation technology and reclamation modes.It formes the major technology system with landform reshaping,soil reconstruction,and vegetation restoration;Land reclamation patterns are diversity,and develops by a single mode to the comprehensive one.[Conclusions]Although there are significant achievements in land reclamation but there are still some problems,such as poor quality of reclaimed land,low reclamation utilization rate,its uneffective role to restore and protect the ecological environment,so the research importants will focus on the determination of scientific reclamation direction,ecological reclamation technology and integrated reclamation modes in land reclamation of coal mining area.
