广东省矿山环境恢复治理遥感监测及评价

Remote sensing monitoring and evaluation of mine environment restoration and management in Guangdong

为了准确监测并评价广东省矿山环境恢复治理工作,文章以多种高分辨率遥感数据为基础,辅助最新矿业权数据、基础地理地质数据等,采用遥感(RS)与地理信息系统(GIS)一体化的方式,提取了研究区内矿山恢复治理专题信息并对其矿山环境恢复治理成效进行评价。结果表明:①工程恢复的周期更短,恢复速率更快;②治理后地类以林地、草地和水域为主;③金属矿山的治理率远低于能源矿山和非金属矿山,其恢复治理难度更大;④在矿山占地基数小的市,治理率高,反之亦然。研究结果对其他区域的矿山环境恢复治理工作具有借鉴意义,同时也能为地质环境保护等矿政管理中心的工作提供参考数据。

In order to accurately monitor and evaluate the mine environment restoration and management work of Guangdong province,in this paper,high-resolution remote sensing data were applied,combined with the latest mining rights data,basic geographical and geological data to extract the special information on mine restoration and management in Guangdong province by the means of RS and geographic information system(GIS).In addition,the effectiveness of mine environmental restoration and management was evaluated.The results showed that:(1)The effectiveness of artificial restoration was faster than natural restoration.(2)Forest land,grassland and water werethe main land types of Guangdong mine environment restoration.(3)The restoration and management rate of metal mines wasmuch lower than that of energy mines and non-metallic mines.So,the metal mine wasmore difficult to restoration and management.(4)The restoration and management rate was high in cities with small mine area,and vice versa.The results of the study could be reference for the mine environment restoration and management in other regions.At the same time,it could also provide reference data to mine management department.
