SWAT模型数据库的构建——以赵王河流域为例

Construction of Database for SWAT Model in Zhaowang River Basin

近年来,SWAT模型被广泛应用于水文、水利、面源污染等方面的研究,但是由于SWAT模型是美国农业部研究中心研制开发的,其基础数据也是以美国本土的数据为标准的,因此,为了提高模拟的准确性,需要建立研究区域的数据库。SWAT模型数据库非常庞大且对数据格式的要求也很严格,因此,其构建过程就成了很多研究人员的难题,针对这个问题,结合已有的数据库构建研究和赵王河流域SWAT模型的构建过程,提出了比较全面的SWAT模型数据库的构建方法。

In recent years, soil and water assessment tool （SWAT） model is widely used in many fields such as hydrology, hydraulics and non - point source pollution. As SWAT model is developed by research center of United States Department of Agri- culture, its basic data is based on American data. In order to improve the accuracy of simulation, it is necessary to build the data- base of studied areas. The database of SWAT model is huge with strict data format. Consequently, the construction of its database has been a puzzle for many researchers. In order to solve this problem, relatively comprehensive construction method of SWAT model database was put forward based on the exiting researches and experience of SWAT model construction in Zhaowang River basin.
