黑龙江省黑宝山-木耳气盆地环境地质问题及防治对策

Environmental geological problems and control countermeasures of Heibaoshan-Muerqi Basin,Heilongjiang Province

文章介绍了黑宝山-木耳气盆地的经济地理条件,地质环境背景,阐述了盆地的主要环境地质问题。第一环境地质问题即自然环境中存在的与地质有关的各种问题,它是由内动力地质作用和外动力地质作用引起的;区内主要有冻土。第二环境地质问题即由于人类各种工程、经济活动而引起的与地质环境有关的问题;如水土流失、矿井塌陷、地表水、地下水及土壤污染等。论述了各环境地质问题产生的地区,分析了各主要问题的特征,形成条件及危害。

This paper introduced the economic geographic condition and geologic environmental background of the Heibaoshan-Muerqi Basin, and expatiated the main environmental geologic problems of the basin. There are many environmental geologic problems in the basin, which can be classified as the first environmental geologic problem and the second one by the formation factors. The first environmental geologic problems are the all kinds of problems involved with geology exsiting in the natural environment, which are cause by the exogenic geologic process and the endogenic geologic process. Permafrost soil distributs in the area with the first environmental geologic problems. The second environmental geologic problem is caused by human engineering and economic activities, such as soil erosion, mineral well subsidence and earth＇s surface water, ground water and soil pollution etc. The paper discussed the region of each environmental geologic problem occurring, and analyzed on characteristics, formation and harm of each key problem. The environmental geologic problems inside the basin are more outstanding, especially the ones induced by human activities, having resulted in much harm at different degrees, therefore it must attach enough importance to them and take prevention and cure measure.
