黑河流域生态环境演变研究综述

随着生态环境问题的日益突出,区域生态环境演变研究成为生态环境研究领域的热点.黑河流域位于河西走廊农牧交错带上,是典型的生态敏感区.近年来流域生态环境严重退化,成为我国区域生态环境演变研究的重点地区之一.分别从黑河流域生态环境退化状况、生态环境演变及驱动力等方面对已有的研究成果进行总结:在气候变化与人类活动的共同作用下,黑河流域生态环境以不同的时间尺度在发展演变.近年来,人类不合理的活动导致一系列生态环境问题的出现.指出当前研究中存在的不足:主要集中于黑河流域生态环境现状研究,缺乏历史时期流域生态环境演变研究.期望为今后黑河流域及其他内陆河流域生态环境演变研究的深入提供参考.

Review of the Evolution of Ecological Environment in the Heihe River Basin

With the coo-environmental problems have become increasingly prominent, the regional research on the evolution of ecological environment is increasingly becoming a hot spot. The Heihe River Basin located in the farming-pastoral belt in Hexi Corridor is a typical example of ecologically sensitive areas. In recent years, the ecological environment in Heihe River Basin degradated seriously. It attracts the attention of many researchers. The paper summarizes the existing research results in the evolution of ecological environment, the status of ecological environment and the driving force of the evolution of the ecological environment: with the climate change and the human activities, the ecological environment in Heihe River Basin developed and evoluted with different time scales. In recent years, human unreasonable activities lead to a number of coo-environment problems. The paper pointed out that the current research focuses on the status of ecological environment and lacks the ecological environment changes in the historical period,in order to provide a reference for the future research on the evolution of the ecological environment in Heihe River Basin and other inland river basins.
