矿区土地复垦的两大主要任务是地面整治及地面整治后的土地再利用,而地面整治又是实现土地再利用的基础和准备,本文在分析采矿引起的耕地破坏特征及其原因的基础上,提出了预防及整治塌陷地的四类工程措施,即(1)采矿措施;(2)降低潜水位措施;(3)农业耕作和灌溉措施;(4)抬田措施。本文还进一步对土地复垦的特点作了分析,给出了选择土地复垦方案的流程图,成功地将层次分析法用于土地复垦工程措施的选择并给出了实例。
The two major tasks of land reclamation in the mining area are land reclamation and land reclamation after land reclamation. Ground reclamation is also the foundation and preparation for land reclamation. Based on the analysis of the characteristics and causes of the cultivated land destruction caused by mining , Proposed four kinds of engineering measures to prevent and rehabilitate the subsidence areas, namely (1) mining measures; (2) measures to reduce the diving position; (3) agricultural cultivation and irrigation measures; This article further analyzes the characteristics of land reclamation, gives the flow chart of land reclamation plan selection, and successfully uses AHP for the selection of engineering measures for land reclamation and gives examples.
