石灰岩露天采石矿区土地农用复垦类型划分研究

Land Agricultural Reclamation Type Classification in the Limestone Open-Pit Mining Area

矿区土地复垦是社会经济发展到一定阶段解决矿区土地利用问题的必然选择,复垦类型划分对指导土地复垦的科学发展具有重要意义。本研究以满城县李兵露天采石场废弃地立地特性调查资料为基础,运用GIS空间叠加法对研究区进行了矿区土地农用复垦类型划分的研究,并对划分结果从复垦类型空间分布、总体数量结构和复垦效益三个方面进行分析,得出结论:构建的矿区土地农用复垦类型划分体系科学合理的将研究区土地划分为宜耕地区、宜园地区、宜林地区和宜牧草地区四个类型区域,并取得十分显著的综合效益。本文以矿业快速发展的满城县为研究区,得到的土地复垦类型划分符合实际生态保护和建设发展需求,为建立矿区土地复垦理论体系与技术规范提供一定的依据。

Mine land reclamation is the social inevitable choice to solve the land use problems to a certain stage of economic development. The partition of reclamation type is important to scientific development of land reclamation. Based on the characteristics survey of open-pit quarry wastelands in Mancheng County, using GIS spatial overlay method, the study was conducted to investigate the partition of agricultural reclamation type of mine land. Results showed that the study area could be partitioned to four types of areas according to the partition system, i.e. the arable land area, garden area, forestland area and grassland area, which would be achieved very significantly comprehensive benefits. This would provide a basis for establishing a mine land reclamation theoretical system and technical regulations.
