新疆地质环境主要问题

MAIN PROBLEM OF GEOECOLOGICAL ENVIRONMENT IN

新疆气候干旱,降水稀少,蒸发强烈,水资源相对短缺且时空分布不均.山区、沙漠、盐碱地、戈壁占地面积大,分布广泛,植被稀疏,绿洲分布有限,生态地质环境脆弱.盆地及周围地质环境破坏严重.山前平原,人类活动集中,工程建设引发的水资源失调、枯竭,水质恶化,植被消减,土地荒漠化、煤层自燃等问题日益突出.这些问题威胁制约着区域生态环境的良性循环.本文从原生地质环境和次生地质环境及地质灾害方面,论述区域地质环境状况,阐明地质环境中存在的主要问题及其灾害,提出综合防治措施.

Because of arid climate, poor and disproportionable precipitation, rare vegetation, geoecological environment in Xinjiang Vygur Autonomous Region is very vulnerable. High proportion of total area, about 166.3×104 km2, is covered with mountainous area, desert and saline alkali soil that their using efficiency is low. Geological environment has been destroyed in Basin area and their surroundings. With human activity, civil engineering and mine exploitation, a number of problems are caused in foreland slope plain, such as ground-subsidence, water pollution, a shortage of water, soil desertification and so on. Geoecological environment that conditioned the circulation of regional ecological environment is becoming worse and worse. Based on the mentioned above, this paper focused on geolgical environment condition, geological hazard and the method of ecological environment protection. Author expatiated the duality of geoecological environment and main problems in geoecological environment that will be referencable for some government working.
