情景规划作为就长期社区计划建立共识和为未来创造区域远景的有效进程，在美国继续获得势头。然而，将更复杂的信息纳入分析框架以帮助确定重要的生态系统服务的努力在实践中滞后了。这是有问题的，因为了解土地消费模式对生态完整性的权衡对于减轻土地使用变化和新开发造成的环境退化至关重要。在本文中，我们描述了如何将生态系统服务价值评估模型，i-Tree，集成到一个主流的情景规划软件工具，展望明天，以评估公共行道树的替代未来发展方案的好处。该工具，然后应用于开发方案，从城市的Hutto，得克萨斯州，得克萨斯州中部可持续发展的地方项目示范社区。这一综合工具是对设想方案规划做法的方法改进，提供了一种将生态系统服务分析纳入主流规划进程的方法，并作为一个实例，说明开放源码软件工具如何扩大可供社区和区域规划考虑的问题范围，即使在社区资源有限的情况下。该工具还为未来的改进提供了空间;可行的选择包括对各种未来土地使用类型的树冠分析，以及适用于更广泛的美国应用的广义行道树模型。(C)2014爱思唯尔有限公司版权所有。
Scenario planning continues to gain momentum in the United States as an effective process for building consensus on long-range community plans and creating regional visions for the future. However, efforts to integrate more sophisticated information into the analytical framework to help identify important ecosystem services have lagged in practice. This is problematic because understanding the tradeoffs of land consumption patterns on ecological integrity is central to mitigating the environmental degradation caused by land use change and new development. In this paper we describe how an ecosystem services valuation model, i-Tree, was integrated into a mainstream scenario planning software tool, Envision Tomorrow, to assess the benefits of public street trees for alternative future development scenarios. The tool is then applied to development scenarios from the City of Hutto, TX, a Central Texas Sustainable Places Project demonstration community. The integrated tool represents a methodological improvement for scenario planning practice, offers a way to incorporate ecosystem services analysis into mainstream planning processes, and serves as an example of how open source software tools can expand the range of issues available for community and regional planning consideration, even in cases where community resources are limited. The tool also offers room for future improvements; feasible options include canopy analysis of various future land use typologies, as well as a generalized street tree model for broader U.S. application.
