我国地域辽阔,但可利用土地资源少,同时由于生产建设和自然灾害等,造成许多优质土地资源损毁。调查清楚土地损毁情况,采取针对性的土地复垦措施,在目前经济发展中显得尤为迫切。以山东某矿区为例,确定了历史遗留损毁土地的划定依据,利用RS与GIS等技术手段对矿区进行地表沉陷预计,用遥感影像提取土地利用变化情况,得到了历史遗留损毁土地的位置、面积和损毁类型等信息,为后期土地复垦与规划提供参考。
Our country has a vast territory, but few land resources are available. At the same time, many high-quality land resources are destroyed due to production and construction and natural disasters. Investigating the situation of land destruction and adopting targeted land reclamation measures is particularly urgent in the current economic development. Taking a mining area in Shandong Province as an example, the delineation basis of the damaged land left over by history was determined, the surface subsidence prediction was made to the mining area by means of RS and GIS, the remote sensing image was used to extract the land use change, the location of damaged land left over by history was obtained, Area and type of damage and other information for the latter part of land reclamation and planning provide a reference.
