城市森林植被-沉积模型（UFORE-D）是一个基于组件的建模方法。该模型的功能被分为负责用户界面，数据输入/输出和核心模型功能的组件。利用组件为基础的方法，三个UFORE-D的应用程序开发：一个基本的应用程序，以估计干沉降在每小时的时间步长，和两个敏感性分析的基础上，蒙特卡罗模拟与拉丁超立方体采样（LHS-MC）和莫里斯一次（MOAT）的敏感性测试。与基础应用，干沉降的CO，NO2，O-3，PM10，和SO2在城市的巴尔的摩估计为2005年。敏感性应用程序进行检查UFORE-D模型参数的敏感性。总的来说，干沉降速率对温度和叶面积指数（LAI）敏感。温度对各污染物的影响呈非线性关系，而叶面积指数对NO2沉降的影响接近线性关系。PAR和风速对所有污染物干沉降的影响有限，干沉降受PAR和风速的影响仅达到其阈值。基于组件的方法允许无缝集成新的模型元素，并为模型开发人员提供了一个轻松交换模型组件的平台。(C)2010爱思唯尔有限公司版权所有。
The Urban Forest Effects-Deposition model (UFORE-D) was developed with a component-based modeling approach. Functions of the model were separated into components that are responsible for user interface, data input/output, and core model functions. Taking advantage of the component-based approach, three UFORE-D applications were developed: a base application to estimate dry deposition at an hourly time step, and two sensitivity analyses based on Monte Carlo simulations with a Latin hypercube sampling (LHS-MC) and a Morris one-at-a-time (MOAT) sensitivity test. With the base application, dry deposition of CO, NO2, O-3, PM10, and SO2 in the city of Baltimore was estimated for 2005. The sensitivity applications were performed to examine UFORE-D model parameter sensitivity. In general, dry deposition velocity was sensitive to temperature and leaf area index (LAI). Temperature had a non-linear effect on all pollutants, while LAI was important to NO2 deposition with a nearly linear effect. PAR and wind speed had limited effects on dry deposition of all pollutants; dry deposition was affected by PAR and wind speed only up to their threshold values. The component-based approach allows for seamless integration of new model elements, and provides model developers with a platform to easily interchange model components. (C) 2010 Elsevier Ltd.
