| 摘 要： | SPARROW(SPAtially Referenced Regressions On Watershed attributes)模型是由美国地质调查局开发的一个基于空间的计算流域营养物质污染负荷的非线性回归模型。它使用机理函数和空间分布模块来计算流域的污染负荷,从而弥补了许多经验回归模型的缺陷。基于模型的特性,其在流域污染负荷核算、水质响应模拟、采样点空间优化、流域最大日最大污染负荷计算与水环境管理等方面有较好的应用前景。对SPARROW模型的机理、结构、输入输出变量、应用现状及在我国的应用发展前景和可能的问题进行了全面阐述和讨论,并对SPARROW模型的改进模型—贝叶斯-SPARROW模型进行简要介绍。以期为该模型在中国水环境管理中的应用提供参考。

| Abstract: | SPARROW(Spatially Referenced Regressions on Watershed Attributes) model is a space-based non-linear regression model developed by the U.S.Geological Survey.SPARROW uses mechanistic functions with spatially distributed components that account for the dendritic features of watersheds,thereby addressing many of the shortcomings of regression-based empirical models.Based on characteristics of model,it has a high application value in quantify pollution load in the basin,simulate response of water quality and even optimization of sampling sites.In this paper,the principle,structure,input and output variable parameters,present situation of application as well as application prospects of the model and problem of using in our country were presented,and improved model-Bayesian-SPARROW model was introduced,in order to offer reference for lucubrating and applying the model in China. |
