摘　　要：为探索复合型可量化的城市生态网络的构建,文章以福州市域为研究范围,通过源地重要性指数dPC值、最小阻力模型、重力模型引力值G_(ab)、网络分析等量化方法,成功识别出福州市域的蓝网和绿网,并基于蓝网保护,识别出25条一级生态廊道和22处生态战略点。在绿网方面,市域范围存在多处绿网密集交错区、生态冲突区等对绿网连接度产生重要影响的区域;在蓝网方面,宽度较窄的大漳溪由于支流密集、汇水区域面积广、位于福州市中心城区上游等因素,对城市重要生态网络的结构产生重要影响;在生态战略点方面,发现有2处连接中心城区与区域生态绿地之间的重要节点需要重点保护。研究成果对福州市国土空间规划及市域绿地系统规划中生态骨架的构建提供参考。This paper takes Fuzhou to explore how to construct the compound and quantifiable urban ecological networks. The quantitative methods of importance index of dPC value, the minimum cumulative resistance model, the gravity model and the network analysis are used to successfully identify the blue and green corridors in Fuzhou City and then 25 first-level ecological corridors and 22 ecological strategic nodes are successfully identified based on blue corridors protection. In terms of green corridors, there are many areas like densely crossed green corridors and ecological conflict zones in the city, which have essential impacts on the connectivity of green corridors in the city. For blue corridors, the Dazhang River, with a narrower width, has an important impact on the structure of the city’s crucial ecological network due to its multiple tributaries, wide catchment area and location in the upper area of Fuzhou downtown. It is found that the 2 important ecological strategical nodes that connect the urban core area with the green spaces in the unbuilt areas need to be protected. The research results would provide a reference for the construction of the ecological framework proposed in Fuzhou’s Territorial Space Planning and Green Space System Planning.
