摘要
利用1992—2017年7个时期的遥感数据,基于遥感生态指数(RSEI),对福建紫金矿区开采以来的生态质量进行评价.结果表明:1)RSEI可以较好反映矿区生态状态的时空变化,1992—2017年,紫金矿重点开发区内裸土面积逐渐扩大,RSEI呈现略微的下降趋势,但整个区域的RSEI反而有一定程度的上升,重点开发区外围的生态状况出现好转;2)从面积上看,占主导地位的区域RESI由“中等”向“优良”发展,说明紫金矿业集团在开发矿山的同时,注重生态保护;3)紫金山矿区不同时期裸土面积扩张的原因与矿区开发技术和金铜价格上涨有关,而矿区生态质量的总体上升与企业和地方政府在生态环境保护方面的大量经费投入密不可分.
Application on remote sensing data from seven periods from 1992 to 2017,based on the remote sensing ecological index(RSEI),the ecological quality of the Zijin mining area in Fujian was evaluated.The results show that:1)RSEI can reflect the spatial and temporal changes of the ecological state of the mining area,during 1992 to 2017,the bare soil area in the key development zone of Zijin Mine gradually expands.RSEI showed a slight downward trend,but the RSEI of the whole region increased to a certain extent,and the ecological conditions around the key development zones improved.2)From the area perspective,the dominant region was from“medium”to“excellent”.Development shows that Zijin Group pays attention to ecological protection while developing mines.3)The reasons for the expansion of bare soil area in different periods of Zijin mining area are related to the development technology of mining areas and the price increase of gold and copper,while the overall improvement of the ecological quality of mining areas and enterprises and the local government’s large investment in ecological environment protection is inseparable.
