Wetland conservation plan has been established to protect ecologically important wetlands based on vegetation integrity,
spatial distribution of endangered species, but recently more demands are concentrated on the landscape ecological
approaches such as topological relationship, neighboring area, spatial arrangements between wetlands at the broad scale.
Landscape ecological analysis and graph theory are conducted to identify spatial characteristics related to core nodes and
weak links of wetland networks in Nakdong basin. Regular planar model, which is selected for wetland networks, is applied
in the Nakdong basin. The analysis indicates that 5 regional groups and 4 core wetlands are extracted with 15㎞ threshold
distance. The IIC and PC values based on the binary and probability models suggest that the wetland group C composed of
main stream of Nakdong river and Geumho river is the most important area for wetland network. Wetland conservation
plan, restoration projected of damaged and weak links between wetlands should be proposed through evaluating the node,
links, and networks from wetlands at the local to the regional scale in Nakdong basin.
