摘要
矿山开采过程中,会产生大量尾矿和废石,露天堆置于山腰、河流附近,不断与空气和水接触后将形成金属离子和酸根离子等污染物,会造成植被生态破坏。本文以我国典型矿山环境为例,选择1986年至2 0 0 0年间的4期TM数据,对矿山开采环境下15年的植被影响进行了分析,采用植被指数法获取15年不同时期植被的相对变化情况,并分析了其变化原因。
Large amounts of waste rock and tailings, which are resulted from the activity of mining, are discarded at the mountainsides or near the rivers. They will produce pollutant, such as metallic ions and acid radical ions which can cause the deterioration of the vegetation environment. This paper selects vegetation indices under the mining environment in the successive 15 years based on Remote Sensing data. Taking the Dexing copper mine which locates in Jiangxi Province as an example and using Landsat TM data in different times during 1986 to 2000 as information sources, a research has been done.
