西藏矿山环境恢复治理现状遥感研究

Remote Sensing Study on the Present Situation of Mining Environment Rehabilitation in Tibet

西藏地处青藏高原,是典型的生态环境脆弱区。为了分析西藏自治区的矿山环境恢复治理现状,利用2016年和2017年获取的卫星遥感数据,采用室内遥感信息提取与野外现场调查验证相结合的技术方法,开展调查研究。调查结果表明,回填平整是西藏最主要的矿山环境恢复治理措施;西藏自治区的矿山环境恢复治理工作取得了一定的效果。总体建议是,在西藏自治区采用自然恢复为主、回填平整为辅、多种恢复治理措施相结合的策略,因地制宜地开展矿山环境恢复治理工作。研究成果可为西藏及同类地区的矿山环境恢复治理规划等工作提供参考。

Tibet,located on the Qinghai-Tibet Plateau,is a typical fragile area of ecological environment.In order to analyze the present situation of mine environment rehabilitation in Tibet,the satellite remote sensing data acquired in 2016 and 2017 and the technical method combining remote sensing information extraction and field investigation were used to investigate and study.Survey results showed that backfill leveling was the most important mine environment rehabilitation method in Tibet.It was believed that the rehabilitation of mining environment in Tibet had achieved certain progress.The general suggestion is that the Tibet Autonomous Region should adopt a strategy of combining natural recovery as the mainstay,backfilling and leveling as the supplement,and multiple restoration and control measures,carrying out mining environment restoration and treatment according to local conditions.The research results can provide reference for the planning of mine environment rehabilitation in Tibet and similar areas.
