摘要
黑叶猴是国家一级保护动物,由于人类活动导致其生境破碎化加剧,威胁种群的生存安全。本文以黑叶猴在重庆的主要分布区金佛山为例,考虑地形、植被、人为活动和饮水因素等,选取与黑叶猴生境密切相关的7个环境影响因子,对黑叶猴生境适宜性进行了分析,并利用最小累积阻力(MCR)模型构建了潜在生境之间的生态廊道。结果表明,黑叶猴最适宜生境面积为178.07 km 2,仅占研究区总面积的12.15%,主要分布在金佛山中部和东北部地区的沟谷地带,潜在生境斑块呈条带状,破碎化状态明显,具有海拔高、坡度陡、临近水源、植被覆盖度高、远离人为活动干扰等特点;构建的生态廊道共有56条,廊道最小宽度为303.9 m,廊道总长度为147.82 km,总面积为43.89 km 2。本文的研究成果对黑叶猴种群和生境的保护具有重要指导意义。
Trachypithecus francoisi,the national first-class protected animal,whose habitat has been destroyed and is in danger due to human activities now.In this study,taking Jinfo mountain,the main distribution area of Trachypithecus francoisiin in Chongqing,as an example,seven environmental impact factors closely related to the habitat are selected from the aspects of topography,vegetation,human activities and drinking water factors,and the habitat suitability of the Trachypithecus francoisito analyzed.The ecological corridor between potential habitats is constructed using the minimum cumulative resistance(MCR)model.The results show that the most suitable habitat area is 178.07 km 2,accounting for only 12.15%of the total area of the study area.The Trachypithecus francoisi mainly distributes in the valleys in the middle and northeast of Jinfo mountain.The potential habitat patches are strip-shaped,obviously fragmented,with high altitude,steep slope,proximity to water source,high vegetation coverage and far away from human disturbance.There are 56 ecological corridors constructed,with a minimum width of 303.9 m,a total length of 147.82 km and a total area of 43.89 km 2.This study has important guiding significance for the protection of the population and habitat of the Trachypithecus francoisi.
