摘要
以新疆硫磺沟矿区1986年和2015年遥感影像数据解译结果为基础,基于GIS空间分析技术,在对其景观变化分析的基础上,评价了煤矿资源开发过程中的生态风险。结果表明:1986-2015年硫磺沟矿区草地面积逐步下降,由98.56%下降到90.99%;工矿地面积逐渐增加,由0 hm^2增加到689 hm^2。1986-2015年矿产资源开发导致硫磺沟矿区景观生态风险升高,草地的生态风险指数最大,工矿用地、未利用地、农田、林地的生态风险均有增加。生态脆弱区矿产资源开发所带来的生态影响应引起足够的重视。
This paper,based on the interpretation results of the remote-sensing image data for Liuhuanggou mining area in Xinjiang in 1986 and 2015,analyzes the landscape changes with GIS spatial analysis technology and then evaluates the ecological risks during the development of coal resources. It turns out that： in 1986-2015,the grassland area in Liuhuanggou gradually decreases from 98.56% to 90.99%,while the industrial and mining area gradually increases from 0 hm^2 to 689 hm^2. The development mineral resources in 1986-2015 causes a rising landscape ecological risk,maximum grassland ecological risk index,and increased ecological risks of industrial and mining land,unexploited land,farmland and forest land in Liuhuanggou mining area. The ecological impact of mineral resources development in ecologically vulnerable areas should attract enough attention.
