Abstrait:

The urban eco-network is the network structure in the urban eco-system that the flowing of substance, population and information have been formed in the spatial distribution. Using Analytic Network Process, MapInfo and GIS, taking Chang de city of Dong-ting Lake Region as an example, the paper analyses the integrity of urban eco-network. The results show that: (1) The characters of connection in the eco-system of forest, farmland and town are very poor between spots, the indexes of alpha, beta and gamma are very low, and the index of alpha appears negative; By comparison, the character of connection of the wetland is a little better, but its index is also low; With regards to the region, its character of connection is much better. (2) The characters of entrance in the eco-function districts is much better, transformational network is relative convenient, especially in the eco-agriculture district. (3) As to the characters of smooth in the eco-system of forest, wetland and farmland, 5 eco-function districts are the best, and 3 eco-function districts are the worst in the 17 eco-function districts.
