摘要
为了研究废弃露天矿山生态修复治理现状及发展趋势,以郑州市矿区为例,结合无人机遥感调查、野外实地调查等技术,明确了研究区域生态修复治理现状,即当前矿山土地资源破坏总面积约为19 105 000 m^(2),仅有9%的土地资源完成了生态修复。经过治理的矿区土壤有机质含量为6.6 g/kg,植被资源覆盖度为25.07%,空气达标率为80%,区地上地下水资源均呈现出匮乏状态。当前矿山生态修复取得了一定效果,但需要进一步完善。根据区域生态修复治理现状,从土地资源、土壤适宜性、水资源分布、植被资源覆盖、水土流失、空气质量等方面出发分析矿山生态修复治理未来发展趋势,以期保障相关生态修复治理工作的顺利进行。
In order to study the abandoned open-pit mine ecological restoration management status and development trend, taking the mining area of Zhengzhou as an example, combined with UAV remote sensing survey, field investigation technology, clear research area ecological restoration management status, namely the current mining land resources damage a total area of about 19 105 000 m^(2),only 9% of the land resources completed the ecological restoration.The average soil organic matter content in the treated mining area is 6.6 g/kg, the coverage of vegetation resources is 25.07%,the air standard rate is 80%,and the aboveground groundwater resources in the area are scarce.At present, the mine ecological restoration has achieved some results, but it needs further improvement.According to the current situation of regional ecological restoration and management, the future development trend of mine ecological restoration and management is analyzed from the aspects of land resources, soil suitability, water resources distribution, vegetation resources coverage, soil erosion and air quality, in order to ensure the smooth progress of relevant ecological restoration and management work.
