摘　　要：生态修复是国家"城市双修"战略的主要内容,而生态网络的建构与修复是生态修复的核心内容。目前社区生态网络研究存在着成果少、应用难、目标单一、方法复杂等问题。在快速城市化进程中,需要简洁实用、物种数据依赖少、可行性强的社区生态网络规划方法。本文基于Forman的"最优景观格局"理论(P),整合Hellmund的生态网络模型(N),结合网络指数、景观格局指数等网络与廊道质量评估方法,提出社区生态网络规划的一种PN模式和5种衍生模式,5种衍生模式可以相互组合,以适应不同的社区形态要求。通过曲线社区生态网络规划的实践,证明应用PN模式规划对于提升社区生态网络质量具有明显价值,是一种可行的社区尺度生态网络规划方法。The ecological restoration is the main part of current Ecological Restoration and Urban Repair strategy, in which the construction and restoration of ecological network is the core of ecological restoration. The study of community ecological network has many problems, such as fewer achievements, difficulties to apply, single goals, and complex methods. In the process of rapid urbanization, there is a need for planning methods of community ecological network which are simple, practical, less-dependence on species data and strong feasibility. Based on Forman＇s theory of Optimal Landscape Pattern（P）, the study integrates Hellmund＇s Ecological Network Model（N）, combining the evaluation methods of network and corridor quality of the network indices, landscape pattern indices etc., this paper proposes one PN model and five derivative ones for the community ecological network planning. The five kinds of derivative models could combine with each other to adapt to different requirements of community forms. Through the practice of ecological network planning in Quxian community, it proves that the PN model planning has obvious value for improving the quality of community ecological network, which is a feasible planning method for the community-scale ecological network.
