( 3 ) anns are often viewed as black box models whose parameters do n ' t have any physical meaning . and the structures of anns are similar in different hydrologic systems , by this mean , the basic information such as distributing of hydrometric stations ca n ' t be utilized . this paper presents a new flood forecast model based on complex ann , which can make the information of hydrologic systems as guidance when constructing the structure of ann ( 3 )通過建立復合型型人工神經網絡模型的方法,有效的利用給定水文系統的先驗知識為人工神經網絡模型的建模提供指導,使得建立出的模型更具合理性,該方法不同于傳統的人工神經網絡建立方法,為基于人工神經網絡的洪水預報建模提供了一種新的思路。

Based on the analyses of water quality monitoring data of over 120 hydrometric stations in the yangtze river system during the last 30 years , the effect of lithology and climate rainfall on major ion chemistry of the river water has been studied by means of statistical approaches such as principal component analysis and correlation analysis 在分析長江流域120余水文站點近30年水質監測數據的基礎上,運用主成分分析相關分析等數理統計方法研究巖性和氣候條件降水量對長江水系河水主要離子化學的影響。
