SWAT模型之初步探讨

由美国农业部农业研究中心(USDA-ARS)研发的分布式水文模型:水土评估工具(SWAT).具有强大的物理机制.近年来.它被认为是最适合模拟存不同土壤、土地利用和管理大流域中,长期土地管理对于水、土沙、营养物质及农业化学物质的影响.介绍SWAT模型的原理及基础数据库之建立,并搜集SWAT模型应用研究之文献(1999-2008年),以统计分析SWAT模型目前的研究现况,作为日后应用SWAT模型进行相关研究之参考.

Primarily Study for Soil and Water Assessment Tool (SWAT)

The Soil and Water Assessment Tool (SWAT) is a kind of distributed hydrologic model, it was developed by the USDA-ARS. In recent years, it is considered as one of the most suitable models for predicting long-term impacts of land management measures on water, sediment, and agricultural chemical yield (nutrient loss) in large complex watersheds with varying soils, land use, and management conditions. This paper introduced the principles and established the foundational database of SWAT, to collect the reference papers of the SWAT model (from 1999 to 2008) for statistical analysis, regarding to the application in the future.
