青海湖裸鲤资源与流域内人类活动关系分析

The relationship between Gymnocypris Przewalskii resource in Qinghai Lake and the human activities in watershed

青海湖是青藏高原地区一个重要的生态区域,该流域内生态环境的演变与区域内的人类活动有着不可忽视的关系。其中,流域内所特有的青海湖裸鲤资源的由盛转衰,是人类活动对该区域生态环境影响的一个缩影。以青海湖流域内的农、牧、渔业生产数据为基础,分析了该流域内人类活动对裸鲤资源的影响。结果表明:人类活动对该区域生态环境影响的广泛性、盲目性和活动主体对生态环境问题认识上的滞后性是造成青海湖裸鲤资源由盛转衰的根本原因。

Qinghai Lake is an important ecological area in Tibetan Plateau,where the ecological environment and human activities within the region have a negligible relationship. The gloom and doom of the basin- specific Gymnocypris przewalskii resources showed the impact of the human activities on the regional ecological environment. Based on the data of the farming,animal husbandry and fishery in the Qinghai Lake basin,we analyzed the impact of the human activities within the area on this fish resource. The results showed that the root cause of the Gymnocypris resources changed from the gloom to doom was that the hysteresis quality of human＇s awareness on the environmental issue and the extensive and blind of the human activities which affected the ecological environment of the region.
