基于多时相遥感的硫磺沟地区矿产资源开发及环境变化研究

Study of mineral development and environment variation in the Liuhuanggou mineral district Based on Remote Sensing data.

本文以天山硫磺沟矿区为示范研究区,在资料收集和野外调查分析基础上,利用1975年以来30年监测的遥感数据,提取研究区煤、铁、粘土等矿床开发区的时空分布和生态环境时空变化信息,结合数理统计方法和GIS空间分析技术,对矿区矿产开发与土地利用变化进行综合研究,分析硫磺沟矿区矿产开发引起的环境问题,建立1975年以来矿区开发与环境变化定量评价模型,绘制主要矿产分布、生态环境变化等专题图件,直观展现了矿产开发所引起的生态环境问题;探讨30年来矿产开发对自然和人文环境系统影响的过程和机制,确定不同类别矿产开发引起的环境变化和资源破坏的动态趋势,在此基础上提出相应的管理建议。

By using remote sensing data, temporal and special change of mineral distribution as well as environment variation at the Liuhuanggou mineral district was extracted. Spatial analysis, field work and statistical methods were employed to study dynamics of mineral development and corresponding eco-environment effect. A quantitative analysis model （time span： 1975 -2004） of mineral development and subsequently eco-environmental effect was constructed, and environmental problems caused by mineral development were explored. Furthermore, those problems were also revealed straightforwardly by the thematic maps of mineral distribution and corresponding eco-environment variation in this study. Magnitude and tendency of land use change imposed by mineral development during the recent 30 years were discussed. Based on the study, policy suggestions were put forward.
