| 摘 要： | 通天河是长江源区最大干流,其径流与基流的变化基本上反映了整个源区的水文与水文地质特征.根据长江源区通天河流域的径流变化及区域水文地质条件等特征,首次选用改进加里宁方法计算了通天河直门达水文站1957-2009年实测径流量的基流;分析了该流域基流量的多年变化,研究了拐点流量Q0、退水指数α值及比例系数B值与基流量的关系....

| Abstract: | In recent years,vegetation degradation,wetland shrinkage,lake diminution in the source region of the Yangtze River located in the middle area of the Tibetan plateau,have been the serious eco-environmental problems,which have drawn the attention of scientists and society.According to field study,it refers that these problems could be caused by the local groundwater conditional changes.Baseflow is the main way of regional groundwater drainage and supply to stream,which has ability to maintain the local eco-en... |
