气候变化和人类活动对孤山川流域次洪径流量和输沙量的影响

The Impacts of Climate Change and Human Activities on Flood Runoff and Sediment Transportation in Gushanchuan Basin

利用有序聚类法、MWP检定法分析出1979年为孤山川流域天然时期和人类活动影响时期水沙的转折点,采用1979年之前的资料建立模型,并将该时期的次洪水量和沙量作为基准,分析了气候变化和人类活动对1979年后次洪水量和沙量的影响。

The turning point of water and sand of natural period and human activities impact period in Gushanchuan Basin is the year 1979, which was analyzed with the method of orderly clustering and MWP test. The model was established with the data before 1979, and the runoff and sediment transportation during this period was regarded as benchmark value. The impacts of climate change and human activities on the quantity of water and sediment during floods after 1979 were analyzed.
