摘要
为调查广西大厂锡多金属矿田和高龙金矿区近20a来生态环境人为破坏情况,采用了Quickbird-2和SPOT-1卫星遥感技术。研究表明,Quickbird-2的1、4、2或2、4、1波段与Pan波段融合影像具有很好的矿山生态环境识别效果,可以用于米级尺度的大比例尺矿山环境调查任务。SPOT-1Pan波段与Landsat-7ETM+7、5、4波段数据融合可以用于10m级的中比例尺矿山环境调查任务。本文还从遥感角度讨论了矿山生态环境破坏对地球生态系统造成的影响。
To investigate the eco-environmental destruction in the Dachang and Gaolong mines in Guangxi, the authors used Quickbird-2 & SPOT-1 remote sensing technology. It is known from the study that the fusion image formed by band 1,4,2 or 2,4,1 and band Pan of Quickbird-2 is effective in recognizing different ecological environments of the mines. Therefore, the technology can be applied to environmental investigation on the large scale and also at the 1-meter-level scale. The fusion image formed by band Pan of SPOT-1 and band 7,5,4 of Landsat-7 ETM^+ can be applied to environmental investigation on the medium-large scale and also at the 10-meter-level scale. On such a basis, this paper further discusses the effects of the eco-environmental destruction in mines on the whole ecological system of the earth.
