黄河源区水文气象要素变化对生态环境的影响

The impact on ecosystem environment of Yellow River Source Rcgion from the variety of hydrology and meteorology

根据黄河源头地区的降水、蒸发、径流等水文气象要素多年变化资料,并结合20世纪70～90年代的卫星影像资料的分析,认为气候变化和人类活动等因素极大地改变了黄河源头地区生态环境的格局,是影响黄河源头生态环境的主要因素。

s:Based on the data of hydrologic and meteorological factors over the years such as precipitation, evaporation, runoff in the origin area of the Yellow River, and in combination with the analysis of the satellite image data from 1970s to 1990s of 20th century, it is concluded that the climate changes and human activities greatly changed the patterns of ecological environment in the origin area of the Yellow River and are the main factors affecting the ecosystem environment in this area
