短期局部公路修建工程影响下马鹿藏南亚种潜在适宜生境分布区变化
Changes in potential suitable habitat distribution of Cervus elaphus wal-lichii affected by short-term local highway construction projects
摘要
Abstract
The construction of roads around towns and villages lies in the mutual infiltration between urban and natural complex systems,often impacting the distribution of wild animals.This study employed the optimized maximum entro-py model to predict the potential suitable habitat distribution of Tibetan red deer(Cervus elaphus wallichii)both before and after the construction of a new road in Zengqi Township,Sangri County,Shannan City,Xizang Autonomous Region,during the two lean seasons in 2021 and 2023.The findings reveal that road infrastructure and climate change are the pri-mary environmental factors influencing the suitability of Tibetan red deer's habitat.Following the construction of the new road,the cumulative contribution rates of climate and road infrastructure reached 29.5％and 47.6％,respectively.The area with temperatures ranging between-7 ℃ and-9 ℃ to-11 ℃,an altitude of approximately 3 900 m,and prox-imity to rivers exhibits the highest probability of Tibetan red deer occurrence.The suitable habitats are primarily concen-trated along the road to the north of Zengqi Township and in the nearby mountains.After the construction of the new road,the area of suitable habitats expanded by 0.83％compared to pre-construction.The center of suitable habitats shift-ed eastward overall,yet the potential suitable distribution area remained largely unchanged along the road,indicating no evident avoidance behavior by the Tibetan red deer population.This study demonstrates that short-term highway con-struction has not significantly impacted the suitable distribution area of Tibetan red deer in Zengqi Township;however,ongoing monitoring for long-term impacts is necessary.关键词
