摘要
西北地区自然气候条件恶劣 ,地质条件差 ,降水少且集中 ,旱涝灾害频繁 ,植被稀疏 ,水资源短缺 ,存在着沙漠化、水土流失、滑坡、崩塌、泥石流及草场退化、耕地面积减少等严重生态环境地质问题。而煤矿山的无序开发 ,造成该区的地质环境和生态系统十分脆弱 ,严重制约了区内资源的开发和社会经济的可持续发展。本文通过对煤矿山地质环境与生态系统主要问题的现状的详尽分析 ,提出应用“3S”技术评价的思路 。
The natural climate in Northwest area in China is very odious, and its geological condition is very complex. The precipitation is less and concentrated. Drought and waterlogging in the area are very usual to see, and the eco system is very weak. Water resources in the area are limited. The eco environment problems such as aditic, loss of soil, mud rock flow, earth slide, land degeneration and decrease of cultivation area are quite common in the area. In the meantime disorder exploitation of coal mine in the area has made the geological environment and ecology system more fragile. Based on analyzing the problems in detail, This paper puts forward to an new thought of applying “3S” to assessment of the problems, and concludes that non linear ANN method is of an advantage to evaluating the problems.
