We aim to develop the management technology of river-basin environment with a quantitative underpinning, and tried to evaluate the environment of birds’ habitats around the nation using ecological niche models(GLM). In the results, ecological niche models for birds showed the important environmental factors and spatial scales differed according to bird species, and detected the relative importance of river environment versus surrounding environment as birds habitats. Thus, this approach in the study can evaluate the river and basin environment integrally, and suggest the quantitative goal on the environmental managements of river basin.
