Abstract:

Constructing ecological network could protect environment, stabilize ecology and enhance ecological value of urban open space. Regional ecological network based on administerial units could represent natural characteristics and ecological function diversity of study area and could guide regional landscape ecological optimizing. In order to highlight the importance of ecological function network of each county or city on the whole Taiwan island and to guide establishing county or city development strategies, this study intends to construct ecological function network in the whole island through researches in counties or cities, and to separately integrate indices of ecological benefit, ecological patterns, and etc. At present, ecological function network centers in Taiwan locate in Hualien and Nantou counties, and ecological function wears off from east to west. Thereafter, according to function network framework, ecological needs estimation, and land value evaluation, this study suggests that Taipei city and other counties should improve their environments.

Key words: ecological benefit assessment, ecological function network, Taiwan island
