摘要
本文主要论述模型多数的初定、率定、检验以及模型计算实例。初定参数的主要依据材料是水文气象资料、自然地理资料、地形图等。以率定周期和检验周期的实例流量过程为校核目标，根据径流量、径流过程和洪水过程制定人－机对话调试方式下的目标函数，以确定性系数Ｄ＿ｙ为自动优化的目标函数，通过水文模拟率定和检验模型参数。本文中列出涪江平武以上流域的水文模拟，说明森林流域水文模型的计算步骤与可靠性；至于如何评价与预测森林水文效应，将另文专论。
Preliminary determination,calibrantion,Check of model parameters and model computation exam-ples are mainly described. Preliminarily determined parameters are mainly based on bydrological and meteoro-logic data,natrual geograghical data and topographic map.The measured discharge hydrograph in calibration period and check period is the objective of check.Objective function unde rman-machine interactive debugging gained from runoff, runoff process, and flood process. Deterministic parameter D_y is defined as automatically optimized objective function, therefore,model parameters can be calibrated and cheaked by hydrological ana-logue. Hydrological analogue in the basin at upstream of Pingwu along the Fu River is shown to demonstrate the computation steps and reliability of hydrological models in forest basin, the assassment and forcast of for-est hydrology effect will be stated in another paper.
