摘要: 以伊敏矿区1975年、1990年和2010年遥感影像数据的解译结果为基础,基于GIS空间分析技术,在对其景观变化分析的基础上,评价了伊敏煤矿资源开发过程中的生态风险。研究结果表明:1975—2010年伊敏矿区草地面积一直在下降,由1975年的87.99%下降到2010年的75.03%;工矿地面积逐渐增加,由1975年的0 km2增加到2010年的19.63 km2。矿产资源开发导致伊敏矿区景观破碎化程度增大,景观连接性降低,景观中优势类型的面积比例随着矿产资源开发逐渐降低。1975—2010年矿产资源开发导致伊敏矿区的景观生态风险升高,草地的生态风险指数最大,林地、工矿地、耕地、住宅用地和未利用土地的生态风险均有增加。草原区矿产资源开发所带来的生态影响应引起足够的重视

Abstract: This paper,according to the remote sensing information of Yimin mining area in 1975,1990 and 2010,uses GIS tool to analyze its scenic changes and to evaluate the ecological risks during Yimin coal resource development.The grass land area had been falling from 1975 to 2010, 87.99% in 1975 to 75.03% in 2010,whilst the mining area had been rising from 0 in 1975 to 19.63 square kilometers in 2010.Mining activities leads to a fragmentation of mine scene,a fall in scenic connecting and in preponderant category in scene area proportion.It implies a rising scenic ecology risk in woods,mining area,farmland,residence land and undeveloped land,highest in grass land,which shall be paid enough attention.

Key words: ecological risk evaluation, scenic change, scenic fragmentation, opencast coal mine, Yimin mining area
