***9817761ClarkeThis Urban Research Initiative (URI) project will develop an integratedmodeling environment (IME) for the cross-disciplinary study of a widerange of questions pertaining to urban change. At the core of IME is amodel of evolving urban spatial structure already successfully appliedto the Baltimore/Washington and San Francisco metropolitan areas. Thisresearch drastically extends the capabilities of the previous model byallowing it to be combined with a variety of other models of naturaland social processes affecting the urban realm, by strengthening itstheoretical and technical base and analytical utility, and byintegrating it within a portable user-friendly environment for theinvestigation of a variety of urban research and policy questions.IME consists of two levels. At the IME-1 level the focus is on thechanging urban spatial structure, as in the earlier model, but now amuch more versatile and sophisticated range of urban growth models canbe built through the linkage with models of other natural and humanurban subsystems. The IME-2 level is for investigating more general,not directly geographic urban research and policy questions, whereurban spatial structure is one of several key factors. The researchplan consists of four interrelated tasks. Task One develops thetheoretical and technical framework for the IME. Task Two demonstratesand tests the validity of the approach at the IME-1 level throughmodeling and analyzing the growth patterns of selected metropolitanregions. Task Three demonstrates and tests the validity of theapproach at the IME-2 level with a study seeking to predict land useintensity and population distribution through coupling of severaldifferent models of physical and human processes, including a model ofurban spatial structure. Task Four focuses on the computationalimplementation and dissemination of the IME. Dissemination plansinclude the development of two (one undergraduate and one graduate)Web-based courses on urban change.***The project is multi-institutional, linking together the University ofCalifornia Santa Barbara and two other major federally funded projects: the Urban Retrospectives/Urban Dynamics initiative at the UnitedStates Geological Survey will provide the data for the metropolitanareas and assist with the more routine modeling work. The UrbanSecurity initiative at the Los Alamos National Laboratory willcontribute advanced expertise on the theoretical and technical aspectsof complex dynamic models, and on the coupling of physical sciencemodels with urban models. It will also provide access tosupercomputing resources where needed.

* 9817761克拉克这个城市研究倡议（URI）项目将开发一个集成建模环境（IME）的跨学科研究的一个广泛的问题有关的城市变化。 IME的核心是演变中的城市空间结构模型，该模型已经成功地应用于巴尔的摩/华盛顿和旧金山弗朗西斯科大都市区。 这项研究通过允许它与影响城市领域的自然和社会过程的各种其他模型相结合，通过加强其理论和技术基础和分析实用性，并通过将其整合到一个便携式用户友好的环境中，以调查各种城市研究和政策问题，极大地扩展了以前模型的能力。 在IME-1水平上，重点是改变城市空间结构，如在早期的模型，但现在更灵活和复杂的城市增长模型的范围可以通过与其他自然和人类城市子系统的模型建立联系。 IME-2级别是调查更一般的，而不是直接的地理城市研究和政策问题，其中城市空间结构是几个关键因素之一。 研究计划包括四个相互关联的任务。 任务一为输入法开发理论和技术框架。 任务二通过对选定的大都市地区的增长模式进行建模和分析，在IME-1水平上验证和检验了该方法的有效性。 任务三演示和测试IME-2水平的方法的有效性，通过耦合几种不同的物理和人类过程模型，包括城市空间结构模型，来预测土地利用强度和人口分布。 任务四集中于IME的计算实现和传播. 传播计划包括编制两个关于城市变化的网络课程（一个是本科生课程，一个是研究生课程）。该项目涉及多个机构，将加利福尼亚大学圣巴巴拉和另外两个由联邦政府资助的主要项目联系在一起：美国地质调查局的城市回顾/城市动态倡议将为大都市地区提供数据，并协助进行更常规的建模工作。 洛斯阿拉莫斯国家实验室的UrbanSecurity计划将为复杂动态模型的理论和技术方面以及物理科学模型与城市模型的耦合提供先进的专业知识。 它还将在需要的地方提供超级计算资源。
