黑河流域生態環境演變研究綜述
摘要： 隨著生態環境問題的日益突出,區域生態環境演變研究成為生態環境研究領域的熱點.黑河流域位于河西走廊農牧交錯帶上,是典型的生態敏感區.近年來流域生態環境嚴重退化,成為我國區域生態環境演變研究的重點地區之一.分別從黑河流域生態環境退化狀況、生態環境演變及驅動力等方面對已有的研究成果進行總結:在氣候變化與人類活動的共同作用下,黑河流域生態環境以不同的時間尺度在發展演變.近年來,人類不合理的活動導致一系列生態環境問題的出現.指出當前研究中存在的不足:主要集中于黑河流域生態環境現狀研究,缺乏歷史時期流域生態環境演變研究.期望為今后黑河流域及其他內陸河流域生態環境演變研究的深入提供參考. Abstract： 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. 作 者： 李靜 桑廣書 劉小艷 LI Jing SANG Guang-shu LIU Xiao-yan 作者單位： 李靜,桑廣書,LI Jing,SANG Guang-shu(浙江師范大學,旅游與資源管理學院,浙江,金華,321004)劉小艷,LIU Xiao-yan(陜西師范大學,旅游與環境學院,西安,710062)
