Green corridor is an important part of urban ecological system

which maintains the stability oflandscape and promotes the exchanges and updates of material and energy.The green corridors of JiaozuoCity were selected as the study objects and their landscape characteristics were analyzed

classified and summarized based on data form field survey and satellite images using ENVI 4.5and ArcGIS 9.2software.Theresults showed that the numbers of green road

river and belt corridors in the city were 24

7and 2

respectively.The features of green corridors were composed of simple community structure and species with lowconstruction ratio.Parts of streams and roads were bare or built using concrete

with low density

construction ratio and connectivity.The density of urban green corridor was 2.86

the construction ratio of green corridor was 0.48

the node of network was 65and the connectivity degree was 0.17

respectively.The greencorridor of the city was in a unreasonable and unhealthy state.The future construction of green corridorshould increase the proportion of green belt

and the length and width of green corridor.Ecological contact ofgreen corridors system should be strengthened with green belts as connection

three horizontal and five longitudinal green river corridor as frame

and green road corridor as network.
