摘要
水文过程要素是流域水文物理机制的反映,能够为流域水资源的利用和保护提供重要依据。以黑河山区流域为研究区域,采用SWAT-GIS集成模型平台进行水文模拟,阐述SWAT模型水文过程要素的计算方法,基于GIS技术,并利用1990～2000年共11年的径流模拟结果数据,对研究区的水文过程要素进行分析,计算分析流域内降水、径流、入渗、蒸散发、融雪等要素的时空变化特征。
Hydrological process factors are the reflection of the physical mechanism of basin hydrology,which can provide important basis for the use and protection of water resources.Taking Heihe River Mountain Area Basin as the study area,the hydrological simulation was made based on SWAT-GIS integrated model platform.The calculation methods of hydrological process factors by using SWAT model were described.Based on the simulation results of runoff from 1990 to 2000,the hydrological process factors in the study area were analyzed by using GIS technology.The spatial and temporal characters of precipitation,runoff,infiltration,evapotranspiration and snowmelt in the basin were calculated and analyzed.
