中亚与我国西北地区环境蠕变问题的分析

The analysis of environmental creeping problems in Central Asia and Northwest China

讨论了中亚和我国西北地区环境蠕变问题,分析了环境蠕变与人类活动,环境蠕变与气候变化的关系.结果表明,在近年全球增暖的背景下,由于人类过度开采和利用水资源,引起了环境进一步恶化;气候变暖加速了环境恶化的进程.干旱、半干旱地区,生态脆弱,当人类活动超过自然承载力时,小的气候波动也可能引起大的环境变化.

The environmental creeping problem in Central Asia and Northwest China was discussed; and the relation of environmental creeping with human activities and climate variation was analyzed. Under the background of whole world increased temperature, the over-utilization of water resource, led to further exacerbation of environment; the climate wanning quickened the course of environmental exacerbation. In the arid and semi-arid regions of weak ecology, small fluctuation of climate might cause large environmental variation when human activity exceeded the natural beating capacity.
