基于卫星遥感数据的江西德兴铜矿开采环境影响动态监测分析

Dynamically monitoring and analyzing the environment of Dexing copper-mine based on remotely sensed data

位于中国南方的江西省德兴矿山开采铜矿已有几十年历史。采矿行为会产生大量废石和尾矿,这些废石和尾矿富含铁化合物,不断与氧气、雨水接触,将形成金属离子和酸根离子等污染物,随着降雨过程迅速在地表大面积扩散,最终流入矿山附近的河流、湖泊等水体,因此会造成植被污染、水环境恶化。基于卫星遥感数据源,针对江西德兴铜矿典型的矿山开采环境,对矿山开采环境内植被及水体的影响进行了动态监测分析,可为矿山合理开发、环境监测与可持续发展提供决策分析方法。

The mine of Dexing in Jiangxi Province located in South China has been exploited for dozens of years. Large amount of the wasted stones and tailings are produced by the mining behavior. They are abolished and rich in the iron chemical compound. After touching with the oxygen, rainwater constantly, they will form such pollutants as metal ion, acid radical ion and so on. These materials will cause the vegetation to be polluted and make water environment worse. Based on remotely sensed data of the satellite, the paper has dynamically monitored and analyzed the influence on the vegetation and water body under the environment of exploiting the mines, which is located in Jiangxi Dexing Copper-Mine. The results show that they can offer the analysis and decision methods for the mine reasonable development, environmental monitoring and sustainable development.
