Abstract

Roads lead to habitat fragmentation, posing a major threat to biodiversity. This study aimed to refine environmental impact assessment (EIA) for road infrastructure in the Hainan tropical rainforest (Hainan Province − China − Asia) by focusing on the multi-scale impacts of different road types on wildlife corridors. Utilizing graph and circuit theories, we evaluated corridors for species with different dispersal capabilities (1 km, 5 km, 10 km, and 15 km). In our results, highways significantly impacted connectivity, especially for long-distance dispersal species. Provincial roads reduced connectivity for species with 1–5 km dispersal. Complex changes were observed for species with 10–15 km dispersal at patch scale. High connectivity patches for species with a 1 km range were primarily within national parks, but overall connectivity between protected areas was insufficient. This research underscores the importance of strategic planning in optimizing protected corridors and offers suggestions to mitigate the negative impacts of road infrastructure on ecological connectivity.

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.
