乌伦古河流域SWAT模型基础数据库构建

Construction of basic database for SWAT model in Wulungu River basin

以西北内陆干旱区新疆乌伦古河流域为例,构建了乌伦古河流域SWAT模型土壤属性和气象数据库。土壤数据库的构建过程为:通过查阅《新疆土种志》获得所需基础土壤数据;运用MATLAB编程转换土壤粒径;采用SPAW软件计算土壤的水分参数。气象数据库的构建过程为:在中国气象共享服务网上下载地面气象数据并整理该数据为所需格式;运用SwatWeather.exe软件计算降水、气温、露点、风速和辐射数据,从而获得SWAT模型天气发生器参数。成功构建SWAT模型基础数据库,为模型在此流域的应用奠定基础。

Taking Xinjiang Wulungu river basin of northwest inland arid areas for example, the paper built SWAT model about soil properties and meteorological database in wulungu river. The construction process of soil database is that by looking at the soil species in xinjiang to obtain the needed foundation soil data; by using the MATLAB programming to converse soil particle size and applying SPAW software to calculate parameters of soil moisture . The build process of weather database is that downloading the ground meteorological data in China Shared service online and to sorting the data as the required format; using swatweather, exe software to calculate precipitation, air temperature, dew point, wind speed and radiation data, while obtain the swat model weather generator parameters. The SWAT model based data- base built successfully laid the foundation for application of the model in this basin.
