Urban greenways are proven strategies to counter ecological fragmentation and improve urban sustainability. However, significant challenges remain when seeking to integrate multiple functions into priority-oriented planning. In this paper, we focus on the city of Wuhan (China) to present an innovative approach for developing multi-functional greenway networks. Based on remote sensing and geographical information systems, this approach applies a least-cost path model, a kernel density analysis and a proxy index to identify and integrate multiple needs into priority greenway networks. Our priorities are bird and small mammal conservation, human recreation and water protection. In the cost settings of the least-cost path model, we include simulated construction costs to realistically identify corridors. This method insures that our results reflect the expenses necessary for the construction of greenways. Our study demonstrates that the kernel density method is an effective tool to illustrate priorities by revealing the potential utilisation intensity of corridors. Based on the proposed method, we identify eight potential greenway networks, each highlighting different sets of priorities. We divide these priority greenway networks into three categories of ecological security: ideal greenways, backbone greenways and the comprehensive greenway network. The latter represents the integration of animal conservation, human recreation and water protection objectives. Because priorities can be added, interchanged or weighted according to local specificities, our study offers a methodological framework applicable to developing and developed cities.
