Abstract

Quantifying the utilization of wildlife crossing structures (CSs) requires considering the local population background. This study assessed the effectiveness of 22 CSs based on the abundance of two ungulates (khulan and goitered gazelle) in northwestern China and analyzed variables influencing their usage such as openness, water source, and human activities in drylands. Results showed that there were 7 and 13 CSs with higher performance indices (PRi) for khulan and goitered gazelle, respectively. Khulan favors CSs near water sources and with large openness, while goitered gazelle prefers structures that include ponding and also feature large openness. Factors like distance to the CSs of the railway, predators, and human activities affect the utilization of CSs by goitered gazelle. This study emphasized the importance of designing and managing effective wildlife CSs by focusing on openness and water resources. It is recommended that CSs can be spatially consistent in multiple transportation lines run parallel.

影响中国花羚和鹅喉羚利用穿越结构的因素

量化野生动物通道结构（CS）的利用率需要考虑当地的种群背景。本研究根据中国西北地区两种有蹄类动物（呼兰和鹅喉羚）的数量，评估了22个CS的有效性，并分析了影响其使用的变量，如干旱地区的开阔程度、水源和人类活动。结果表明，库车和鹅喉羚分别有 7 个和 13 个性能指数（PRi）较高的 CS。库兰羚偏爱靠近水源且开阔的CS，而鹅喉羚则偏爱包括池塘在内且开阔的CS。与铁路CS的距离、捕食者和人类活动等因素都会影响鹅喉羚对CS的利用。这项研究强调了通过关注开阔度和水资源来设计和管理有效的野生动物保护区的重要性。建议在多条交通线路并行的情况下，CS 在空间上保持一致。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
