| 摘 要： | 研究目的是采用水文模型系统(HMS)模拟峨嵋河流域暴雨水文过程,并为长江上游地区气候和水文响应研究提供可靠的信息。HMS是一种分布式水文模型可用于研究各种气候因子和地表覆盖变化而引起的水文过程响应,该系统(HMS)利用气象、土壤类型、土地利用和地表覆盖、数字高程(DEM)和降雨径流等资料,研究气候、陆面、地表水和地下水的相互作用机理。在本次研究中,采用SCS Curve Number(CN)和Green-Ampt(GA)方法来计算径流过程,用GIS来数字化DEM、土壤、土地利用和陆地覆盖数据。通过用不同时间间隔的降雨和不同计算方法的水力参数模拟水文过程,来检验降雨的时间尺度效应和水力参数的空间变异性对水文过程的影响。结果表明,HMS对峨嵋河流域暴雨洪水的模拟及预测具有较好的适用性。

| Abstract: | The objective of this study is to simulate the hydrologic responses to a single-storm event with a distributed hydrologic model system(HMS) in the Emei Watershed and to provide information for the study on the interactions between regional climate and hydrologic system in the upper Yangtze River.HMS was designed to study hydrologic processes and systems responding to various climatic factors.HMS utilizes spatial information on climate,soil type,land use and land cover,digital elevation,and hydrologic parameters and simulated variables have physical meaning.In this study,the SCS Curve Number and Green-Ampt methods of rainfall-runoff partitioning were used in HMS.The data sets such as DEM,soil,land use and land cover and hydrologic parameters were processed on GIS.The simulations with different time intervals in precipitation and different methods for obtaining hydraulic conductivity were conducted to examine the effects of temporal scale in precipitation and spatial variation in hydraulic conductivity on the hydrologic responses.The application of HMS was demonstrated for the hydrologic simulation in the Emei stream watershed.It was shown that simulated streamflow compares well with the observed data. |
