Research on the location of highway wildlife passage: taking the Tomur as an example

The barrier effect on wildlife is one of the most important ecological impacts caused by highway construction in ecologically sensitive areas. More and more scholars are paying attention to the type and size of animal passages, while there is less research on the scientific site selection of animal passages. Therefore, this paper studies the scientific site selection of wildlife passages during highway construction. In the paper, taking the highway section of the Tomur glacier region in Xinjiang as the study area, the Capra ibex as the study object. Quantitatively evaluate the suitability of animal habitats based on the entropy method, simulate their activity paths through hydrological analysis, and discusses and analyses the results. The research results show that after overlapping with the highway line, the location of the eight animal passages determined are relatively consistent with those determined through field survey. The habitat suitability index fluctuates between 0.117-0.606, indicating low habitat suitability and obvious heterogeneity in spatial distribution. The research results can provide some theoretical basis for the site selection of wildlife passages in the highway transportation and environmental protection industry and respond to the sustainable development of biodiversity.
