广东省典型矿区生态复绿遥感调查研究

Remote Sensing Survey of Ecological Greening in Typical Mines in Guangdong Province

摘要:

以多期遥感数据为数据源，采用人机交互解译方法提取了广东省大宝山多金属矿、云浮硫铁矿、石菉铜矿3个典型矿区生态复绿的位置、面积、变化趋势，结合野外实地调查，查明了矿区生态复绿现状，结果表明：大宝山多金属矿共有3个生态复绿区，生态复绿面积总计约10.08万m2；云浮硫铁矿生态复绿区主要位于东南部采场，面积总计约65.21万m2；石菉铜矿总计有生态复绿区25.4万m2，其中已复绿区15.4万m2，正在复绿区10.0万m2，还有大片区域急需复绿。最后总结了3个矿区生态复绿措施和效果，并提出值得借鉴的地方和存在的不足。该文采用的技术方法能够为其他矿区特别是大范围矿区生态复绿的快速提取提供有益的参考。

Abstract:

Setting multi temporal remote sensing data as the data sources, by using man-machine interactive interpretation method, the location, size, changing trend of ecological greening in Dabaoshan polymetallic deposit, Yunfu pyrite deposit and Shilu copper deposit in Guangdong Province have been extracted. Combining with field investigation, present condition of ecological greening in mines have been identified. It is showed that there are three ecological greening areas in Dabaoshan polymetallic deposit with the total area about 100,800 square meters. The ecological greening areas of Yunfu pyrite mine mainly located in southeastern stope with a total area of about 652,100 square meters. The ecological greening areas of Shilu copper mine is 254,000 square meters, which including 154,000 square meters already greening areas and 100,000 square meters being greening areas, as well as large areas in urgent need of greening. In this paper, ecological greening measures and effect in three areas have been summarized, and the existing problems have been put foward. The technical route and method used in this paper could provide useful references for rapid extraction of ecological greening in the mining area, especially in large mining area.
