南方五省在采稀土矿区遥感监测研究

为研究南方五省在采离子型稀土矿山开发及其对环境的影响,利用北京2号、高分2号、高分1号等多源遥感数据,对该区域2016—2017年在采稀土矿山开发状况和矿山环境进行遥感监测。通过监测发现南方五省在采稀土矿山的生产秩序已经好转；在采稀土矿区整体比较分散,但主要集中分布在江西省赣州市； 2年间稀土矿山整体上呈增加的趋势,增长率为10.5%；在采稀土矿山破坏的生态系统类型主要为林地,同时矿区还存在水土流失、山体滑坡等潜在的风险。

Study on remote sensing monitoring of five southern provinces in rare earth mining area

In order to study the five southern provinces in the production of ion type rare earth mine and its impact on the environment, the use of Beijing No. 2, No. 2, No. 1 high score and multi-source remote sensing data, the region 2016-2017 in the mining of rare earth mine development status and mine environment remote sensing monitoring. According to the monitoring results in five provinces of southern China improve in the mining of rare earth mine production order; scattered in mining of rare earth mining area, but mainly concentrated in the Jiangxi city of Ganzhou province; 2 years of rare earth mine overall showed an increasing trend, the growth rate was 10.5%; in the ecological system of rare earth mine mining damage the main types of woodland, at the same time there are still mine soil erosion, landslides and other potential risks.
