The framework can be referred on the establishment of urban green network. First of all, by reviewing theories and literatures, factors affecting the ecology of urban roads were proposed. These factors were further screened and confirmed through FDH method, correlation and independency analyses. The weighing of each factors were subsequently established by FAHP method to form an ecology evaluation framework for urban road system. The framework was applied empirically on the West District of Taichung City. Strategies to improve the ecology of ecological network of urban road inner space were suggested in order that the urban roads can function as ecological corridors. Thirteen evaluation factors on the ecology of urban road system were proposed which fall into three-level categories of a hierarchy system. The target level is to enable the urban road systems to function as ecological corridors. The first level category includes green network structure (0.6745) and environmental characteristics of road sections (0.3225). The second level category includes four factors, viz. the connectivity of network (0.4660), landscape ecology strategy (0.2085), structure of plant community (0.1787) and disturbance factors (0.1467). The factors fall into the third level of hierarchy system are connected patch area (0.1348), green belt width of road system (0.1145), continuity of road systems (0.2167), etc. In order to improve the landscape ecology of the West District of Taichung City, the ecological network can be developed from the existed greenway system, in conjunction with near-by river corridors to form a more integral green network.
