Abstract

Abstract

The rapid expansion of energy infrastructure， particularly oil and gas pipelines， poses escalating risks to ecologically sensitive regions. This study integrates human activity factors into the InVEST habitat risk assessment （HRA） model to evaluate the cumulative habitat risks in the Chaiwopu area，a vulnerable arid ecosystem in Xinjiang， China. By compiling spatial datasets of three stressors （land for urban/village/industrial-mining use， highway land， and oil-gas pipelines） and nine habitat types， we quantified the exposure-consequence relationships and spatial heterogeneity of habitat risks. The results showed that 8.9% of the study area was subjected to medium-to-high habitat risks， which were mainly concentrated in areas of urban/village/industrial-mining land and along the northern shore of Chaiwopu Lake. Secondary habitats， such as low-coverage grasslands （mean risk： 0.29； maximum risk： 3.91） and artificial woodlands， exhibited higher vulnerability due to their low ecosystem complexity. Although oil-gas pipelines alone had a minimal impact， their coupling with the stressor of highway land amplified the maximum risk intensity by 1.32 times and the mean risk by 24.50 times. Further spatial analysis identified synergistic risks at the intersections of pipelines and highways， highlighting the necessity of coordinated land-use planning. The research findings provide a methodological framework for balancing energy development and habitat conservation， and offer references for sustainable management of ecologically sensitive regions.
