摘要
为揭示黄河源区生态环境恶化的地质原因,本文依据野外调查资料,通过综合分析,认为水环境变异是源区生态环境恶化的主要原因,人类工程经济活动为次要原因。提出的"控制水文网下蚀,提高侵蚀基准面,遏制冻结层上水水位下降,恢复湿地、植被"的生态地质环境治理及保护措施具一定的应用价值。
In recent years the reasons for degradation of the ecologic environment in the headwater area of the Yellow River remain a subject of debate. Changes in water environment and their ecologic\|geologic environmental effects in this area have been analyzed in detail. The results indicate that the changes in water environment are the primary controlling factors and anthropogenic engineering and economic activities are the secodary controlling factors. The protection and control measurements for the ecologic environment in the headwater area of the Yellow River is also proposed in this paper.
