  1. At first, this paper analyzes the factors of water - sand influencing water level of yellow river and the feasibility just using the factors of water - sand to study water level, and collects the corresponding data ; secondly, because there are strong nonlinear relation in the corresponding data, by meticulous theory analysis, this paper integrates basic nonlinear analysis method, theory of random analysis, method of least squares and so on. it puts forward a method which can get the high accuracy simulation of the data, perfects the multi - factor analysis of variable ( over three factors ) of the statistic ; thirdly, it applies the method to the approximation of corresponding water level process which belong to the capacity of sand of middle - high and middle - low, and get the high - accuracy simulation about the typical nonlinear relation ; at last, this paper definitudes the main influence mode that the capacity of sand. it mainly unite with other factors to work on the water level in the yellow river lower reaches ; mor eover, this paper analyzes the difficult point and the direction of improvement to realize the accuracy forecasting of the flood level of erodible - bed channel

    首先，系統分析了影響黃河水位的水沙因素，及僅用水沙因素有效研究水位的可行性，並按變量對應思想採集它們的相應數據；其次，由於相應水位過程數據中含極強的非線性關系，本論文經細致的理論分析，將基本的非線性分析方法、統計建模方法、隨機分析理論、最小均方誤差原則等等數學理論及方法有機揉合，提出了能有效實現這類數據高精度擬合的分層篩選法，並改進了統計學中多因子（三個以上）方差分析法；再次，將這一方法用於黃河中高及中低含沙類洪水相應水位過程的擬合，實現了這一典型非線性關系的高精度擬合，各年汛期上下游相應洪水位過程的擬合誤差都較小；最後，明確黃河下游含沙量對水位的主要影響方式，即含沙量主要是與其它因素聯合對水位作用；另外分析了要實現變動河床洪水位過程準確預報的困難所在及改進方向。
  2. It also explain that the correlation between ssta of kuroshio and the change of wind field in equaroral mid - pacific is results of air - sea interaction ; however, when time comes into summer, the instance status of ocean is different from the last winter to next early springtime, the sea surface temperature turn into the definitive factor, so the increase of heat flux in may to jun month which is realized by absorbing more heat from the sun radiation results in the decrease of sst in kuroshio in the season of jun - jul. finally, during the aug to dec season of next year, the sst of kuroshio is increasing again

    最後分析了黑潮海溫與夏季東亞大氣環流及我國降水的時滯關系，發現：當前冬黑潮區域海溫異常偏高時，後期夏季亞洲低壓的強度減弱，西北太平洋副熱帶高壓強度加強，而且位置西伸、偏北，梅雨鋒位置偏南，長江中下游地區降水偏多，北太平洋冬季海域的海溫分佈呈+ 、 - 、 +趨勢（順序為赤道中東太平洋、西北太平洋、我國近海） ；反之亦然。
  3. Finally, by using of the mathematical model, it is calculated and predicted the effect of the different tongguan riverbed elevations as well as the different conditions of incoming water and sediment on the variance of the flood elevation and the tend of aggradation and degradation of the lower weihe river bed. it is answered quantitively the lessening extent of sediment silt and the decreasing extent of the flood elevation of the lower weihe river after 14 years on two different incoming water and sediment conditions with three different tongguan elevations, respectively 328m, 327m and 326m. these results supply important references to the planning of flood control and comprehensive regulations of the weihe river basin

    最後用驗證后的數學模型對不同水沙系列、不同潼關高程（ 328m 、 327m 、 326m ）下渭河下游的沖淤趨勢和洪水位的變化進行了預測計算，從定量上回答了潼關高程從328m降至327m （相當于潼關高程降1m ）和潼關高程從328m降至326m （相當于潼關高程降2m ）時，渭河下游14年之後各河段的減淤程度以及不同流量級洪水位的降低幅度，這些成果對于渭河下游防洪治理規劃的制定具有重要的參考價值。
