runoff computation 中文意思是什麼
-
By introducing a parameter into the three sources evaporation module of xin ' anjiang model, the whole layers nonlinearity method and the middle layer nonlinearity method were applied to evaporation computation to study the effect of spatial soil evaporation variability on runoff simulation
模擬結果說明模型參數的空間不均勻性對水文過程模擬的影響是很大的。將新安江蒸發模型引入一個新的參數，採用整層非線性方案和中層採用非線性方案來分析土壤蒸發不均勻性對模擬水文過程的影響。 -
It is assumed that model parameters calibrated from measured precipitation - runoff data in a specific period, reflect the situation of land surface and the human activity in that period. firstly, daily data of precipitation, pan evaporation, and discharge in 1960 ' s are used to calibrate the parameters of the xin ' anjiang model. then the parameters calibrated are applied to the computation of daily discharge from 1950 ' s through 1990 ' s, in which daily measured data of precipitation and pan evaporation are taken as the input of the xin ' anjiang model
這種徑流過程代表下墊面和人類活動水準不變情況下氣候波動對徑流的影響，然後利用計算的長系列徑流過程與實測徑流過程對照，其差別反映下墊面的自然變化過程是十分緩慢的，可以忽略，因此這種差別主要代表了人類活動的影響，從前後期率定水文模型所得參數的差別及參數所代表的物理意義來分析下墊面及人類活動的變化，從而將氣候波動和人類活動對地表水資源影響程度定量分解出來。 -
Some developments and results in influence factors of infiltration, computation and analysis of infiltration, hillslope runoff yield and watershed runoff yield in china and other countries are introducted, and some brief reviews on them are given
