River corridor can enhance the ecological of the fragmental habitat and the species diversity. The river corridors should have three function of landscape ecological: (1) It plays the role of passing and habitat corridors of animals. (2) It filters the pollutant. (3) It provides good view and changes the regional microclimate. The factors that affect functions of river corridors include the five factors: the vegetation construction, the width of the river, river corridor connectivity, and the river continuum concept. This paper construct the evaluation method of river corridor by using these five factors. The method is depend on the concept of river connective system. By using different scale of maps to evaluation the entire state of the river. In the study case, to evaluate the Raft River Corridor by using the site photo, 1/5000 and 1/25000. Findings shows that beside the water quality of the Raft River, others conditions present bad ecological quality. Therefore, this study suggests that the improvement of the ecological environment should begin with the small scale.
