Title: The Identification and Simulation of River Hydrological Dynamic Process of Basin System: Forestry Hydrological Effect Evaluation
Abstract: Based on the principle of balance of water input and output of closed basin system, the mechanism model of river hydrological dynamic process in ideal state is given. Within basin the net rainfall input process transferres to the output process of the system in the form of stream flow and water level and through space. The geosphere, ecosphere and human being effect are the factor that affect the river hydrological dynamic process behave. Select the basin system as study object according to human being effect change very little nearly recent 40 years and the forestry state as the greatest ecosphere in land are marked different. Collecting the hydrological and meteorological observation data for nearly 40 successive years recently of the study basin, and Separating the observation data in series samples which are in successive 5 years as one sample as system identification input and output data, then identify the hydrologic dynamic process models of different period. Comparing the differences of river hydrological dynamic process behave in different period and refer to forestry states, the evaluation results of forestry hydrological effect have been given.
