中文摘要	煤炭开发对草地的影响主要体现在对草地的直接破坏和草地荒漠化.以霍林河露天煤矿区为例,基于决策树和BP神经网络,完成了草地荒漠化信息提取,并对研究区16年来的荒漠化情况进行了分析,结果表明:①从1987年至2003年间,研究区荒漠化总面积存在由强转弱、再由弱变强的演变过程,这与气候变化和人为活动有直接关系,但更多的是受气候变化影响的缘故;②轻度荒漠化、中度荒漠化面积同样经历了由强转弱、再由弱变强的演变过程,分析其原因,主要是受气候变化的影响,其次是受超载放牧、掏挖药材以及垦荒等因素影响;③受煤炭开发的影响,重度荒漠化草地多围绕矿业建设用地呈"(▲)"状分布,并且受季风影响向矿业建设用地东侧发展迅速;④重度荒漠化草地面积在16年间始终呈现出高增长的态势,并与矿业建设用地相关关系显著,可将矿业建设用地面积作为评价、预测该区煤炭开发对生态环境影响的重要依据.
英文摘要	Impacts of coal exploitation on grassland are grassland destruction and desertification. In this paper, the desertified grassland in Huolinhe open-cast coalmine was extracted from remote sensing imagey by using decision tree and back-propagation( BP) neural network, and the desertification during the past 16 years in the study area was analyzed. The results indicate that ① from 1987 to 2003 , there is a strong to weak, then weak lo strong evolution process for the total grassland desertification, which can be attributed to climate change and human activities, especially to the influence of climate change; ② there is a evolution similar recess from strong to weak, then from weak to strong for the area of medium desertification and slight desertification, which can be mainly ascribed to the climate changes, then to the over-grazing, uprooting of the medicinal materials, and over-reclamation; ③ due lo the coal exploitation, the severe desertification is always in shape of "▲" around the mining land, and developed lo the east quickly with the help of monsoon; ④ the area of severe grassland desertification is on the increase during the past 16 years, and there is much correlation between the mining land and severe grassland desertification area, so the mining land area can be served as an important indicator for coalfield eco-environment assessment and prediction.
