China is implementing an extensive urban forestry plan in Xiongan New Area (XNA), a new city in Hebei province. The city has been designated to serve Beijing's noncapital functions and promote the integration of the broader Beijing-Tianjin-Hebei city-region. As part of a green initiative to minimize environmental impacts and its carbon footprint, a massive urban forestry system has been planned on an unprecedented scale, expected to cover over 600 km by 2030. Using science to inform policy, one major goal is to simultaneously minimize impacts of invasive species, while making urban forests more resilient to potential invasive species threats. In this review, we introduce these urban forestry plans such as basic concepts and principles for afforestation, tree species to be planted, delineation of existing pests already established, and expected forest invasive species of concern threatening the new area. Finally, we introduce a framework for invasive pest management strategies in XNA based on a "big data" approach and decision system to minimize impacts of invasive species. This new approach to urban forestry has the potential to become an exemplary global model for urban forestry planning, one that integrates research activities focused on forest health surveys and monitoring with sustainable forestry management. Finally, we provide an overview of the forest health policy required for the design of an unprecedentedly large new urban forest from initial planning to full implementation of an integrated forest management program.
中国正在河北省的一座新城——雄安新区实施一项大规模的城市林业计划。该城市被指定用于承接北京的非首都功能，并推动京津冀更大城市区域的一体化发展。作为一项旨在将环境影响及其碳足迹降至最低的绿色倡议的一部分，一个规模空前的大型城市林业系统已在规划之中，预计到2030年将覆盖超过600平方公里。利用科学为政策提供依据，一个主要目标是在尽量减少入侵物种影响的同时，增强城市森林对潜在入侵物种威胁的抵御能力。在本综述中，我们介绍了这些城市林业计划，如造林的基本概念和原则、拟种植的树种、已确定的现有害虫种类，以及可能威胁该新区的令人担忧的森林入侵物种。最后，我们介绍了一个基于“大数据”方法和决策系统的雄安新区有害生物管理战略框架，以尽量减少入侵物种的影响。这种城市林业新方法有可能成为全球城市林业规划的典范，将专注于森林健康调查和监测的研究活动与可持续林业管理相结合。最后，我们概述了从初步规划到全面实施综合森林管理计划，设计一个规模空前的新城市森林所需的森林健康政策。
