The mountainous Minshan region has been the key region for giant panda conservation activities in China. In this paper, we applied the method of graph-theoreticto analyze and assess giant panda habitats stressors and their interactions. The results suggested that there existed 66 combinations between 12 stressors, among which 47.0% of the combinations directly interacted with each other, and 89.2% of interactions of stressors had aggravating effects. There was a strong linkage component K＝{ (TD); (RB); (MI); (HPL); (AP); (AD); (SR); (TH); (FC)}. It meant that these stressors, including tourism activities and site construction, hydropower engineering, transportation, road construction, agricultural development, stock raising and fuel wood collection would create additional impacts on giant panda habitat through the interactions with other stressors. We were able to conclude that these were the predominate stressors for giant panda habitat in Minshan region. The study also demonstrated that graph-theoretic analysis was a useful tool to simplify the reticular interactions within the various giant panda habitat stressors and as a means to identify the main stressors.
