摘要
矿区土地适宜性评价是进行复垦研究的基础。从五峰山煤矿山区地形的实际出发,对煤矿区复垦土地进行适宜性评价。首先,划分评价单元和确定限制因子,然后运用指数和法、极限条件法计算综合指数,得出适宜性评价结果。2种方法综合使用避免了只用一种方法的极端性,最后结合最小限制因素法找出限制因素,以分析不同评价单元适宜的土地复垦方法及类型。在此基础上,结合煤矿区自然地理条件、区位条件等实际情况,提出了2种适合五峰山煤矿区的复垦模式:果草林生态利用模式和生态旅游模式。此外,五峰山煤矿区属于山地煤矿,以其作为研究对象,以便为山地煤矿区合理利用复垦土地提供依据,同时为此类地区复垦土地的适宜性评价和模式研究提供方法和思路。
The land suitability evaluation of mine is the basis of the research of reclamation, by reading a large number of documents, the reclaimed land suitability evaluation is on the basis of the mountainous＇ terrain. First, the author divided evaluation unit and determined the limited factor, then index extreme conditions using index and method and calculation method of comprehensive, it was concluded that the results of the suitable assessment. Two kinds of methods avoided the comprehensive use only in one way, and finally to find limitary factor by extreming with minimum limitation in order to analyze appropriate land reclamation method and type of different assessment unit. In addition, Five Mountains Mountain was mountain-coal-mine, the author focused on it as the research object to provide the rational utilization of land reclamation for mountain-coal-mine, and provide the basis for the similar area.
