摘要

Habitat loss and fragmentation have become the severest threats to wildlife populations. The population of wild forest musk deer (Moschus berezovskii), which is on the endangered species list in China, has decreased by nearly 40% over the past five decades in the Qinling region due to human activities. In this study, we developed a scenario-based integrated framework to quantify human impacts on habitat connectivity in the City of Baoji, Shaanxi Province, the main distribution area of the wild forest musk deer in the Qinling Mountains. In this framework, CA–Markov model is used to predict land cover/use changes, circuit theory is used to identify wildlife habitats and corridors, and connectivity and patency indices are used to evaluate habitat corridors quality. This study focuses on modeling and assessing how future land use changes derived from different development strategies affect habitats and corridors of wild forest musk deer. The results reveal that (1) land use changes significantly affect the habitats and corridors of the wild forest musk deer, (2) the ecological conservation scenario provides robust habitat protection with the lowest fragmentation, and (3) the 2021–2035 planning scenario provides the highest quality protection for corridors. Based on the results, we propose strategies and future land use layouts for coordinating and managing land use changes to prioritize ecological conservation, alleviate the pressure on pinch points, and reduce barriers. It can provide scientific guidance for enhancing wildlife habitat connectivity and the establishing ecological preservation zones in Baoji.
