Transversal Connectivity Index (TCI) for measuring the effectiveness of urban Blue-green infrastructure

This model introduces the Transversal Connectivity Index (TCI) as an ecological indicator for classifying the natural landscape patches by their effective transversal connectivity to the water surfaces. The method applies specifically to urban areas at which the quality of blue-green infrastructure (BGI) is of fundamental importance in reducing the climate change consequences. Effective transversal connectivity among the BGI at the metropolitan scale supplies various ecosystem services in support of nature-based solutions for emerging urban challenges. The TCI value is computed (determined) by integrating a variety of existing and novel landscape indicators into an equation. The connectivity indicators belong to two categories: the intra-patch consists of the isoperimetric quotient , and patch ecological indicator , and the inter-patch ones listed as the band level , the shared border ratio , and the transport fragmentation buffer .

本模型提出横向连通性指数（Transversal Connectivity Index, TCI）作为生态指标，用于依据自然景观斑块与水体的有效横向连通性对其进行分类。该方法专门适用于城市区域：在此类区域中，蓝绿基础设施（blue-green infrastructure, BGI）的质量在减缓气候变化影响方面具有核心重要性。大都市尺度下，蓝绿基础设施间的有效横向连通性可提供多样生态系统服务，为应对新兴城市挑战的基于自然的解决方案提供支撑。TCI值通过将多种现有及新型景观指标整合至公式中计算（确定）得到。连通性指标分为两类：斑块内指标包括等周商与斑块生态指标，斑块间指标则涵盖波段水平、共享边界比率以及交通破碎化缓冲区。（QGIS处理建模器（Processing Modeler- QGIS）将可应要求提供）
