- Abstract
Constructing an ecological network can help mitigate the habitat fragmentation caused by urban expansion, as well as facilitate the survival and migration of species, which is beneficial for biodiversity conservation. We selected Wanyuan, China, for our study, and three different comprehensive resistance surfaces were generated by applying the analytic hierarchy process (AHP), the entropy method (EM), and the spatial principal component analysis (SPCA). Based on these three comprehensive resistance surfaces, three ecological networks were constructed. Then, the ecological networks were quantitatively evaluated to provide a more reasonable theoretical method for the construction of ecological networks in Wanyuan. Meanwhile, the differences between different resistance weighting methods in ecological network construction were discussed. The results indicated that: (1) It was more reasonable to use the SPCA to construct an ecological network in Wanyuan. (2) The weight values generated by the three methods differed significantly. The highest proportion of the AHP was land cover type, consistent with previous research results. However, the weights generated by the SPCA and the EM differed from previous research results. (3) Although the weight proportions of the three methods differed, the distribution areas of high and low values of the three comprehensive resistance surfaces were roughly the same.
