摘 要:
为弄清白头叶猴迁移受公路阻隔的影响,探索可行的栖息地的保护与恢复措施,2012年4月-2019年5月,采用现场调查法和访问调查法,调查广西崇左白头叶猴国家级自然保护区内白头叶猴分布区白头叶猴穿越公路情况,同时运用3S技术研究白头叶猴栖息地路网分布状况。结果显示:调查期间,记录23次包括成体94只、亚成体2只、幼体1只共97只白头叶猴穿越公路现象,其中群体方式穿越14次,独猴穿越9次,致死2只成体雄性独猴。2017年卫星遥感解译,白头叶猴分布区面积102.17km~2,公路网密度0.14km/km~2,白头叶猴历史分布区面积338.23km~2,公路网密度0.22km/km~2。由此可知:(1)板利片那弄旧屯至那弄新屯1.50km路段、生态公园门口至独山0.85km路段、九重山至大栏路口1.0km路段为白头叶猴穿越公路频发和交通致死高发路段,与九重山片和板利片是白头叶猴最集中的分布地有关;(2)由于白头叶猴种群数量增长,九重山片、板利片国道G322以北片区2012年已超出或达到其种群最低容纳群数,而白头叶猴一雄多雌的繁殖策略和领域保护社会属性是导致白头叶猴频繁穿越公路的主要原因;(3)建议兴建"林冠通道"型动物通道、营建生态廊道、建立自然保护小区是减少白头叶猴迁移过程中因公路阻隔致死的有效措施。

摘 要:
In order to find out the impact of road barrier on Trachypithecus leucocephalus migration and explore feasible measures for habitat protection and restoration,relevant field survey and interview survey were adopted from April 2012 to May 2019 to investigate the situation of T.leucocephalus crossing the road at the distribution areas in Chongzuo National Nature Reserve of Guangxi,and 3 S technology was used to study the distribution of road network in the habitat.The results showed that there were no records before 2012 while after 2012,a total of 97 individuals including 94 adults,2 sub-adults,1 larva crossed the road 23 times,among them the groups crossed the roads 14 times and the single ones crossed roads 9 times,2 deaths were caused by traffic and both of them were single males.The area of T.leucocephalus distribution was 102.17 km~2 with a road network density of 0.14 km/km~2 and the area of T.leucocephalus historical distribution was 338.23 km~2 with a road network density of 0.22 km/km~2 by 2017 satellite remote sensing interpretation.The results indicate that:(1)Road sections between Old Nanong village and New Nanong village about 1.50 km in Banli area,between Eco-park and Dushan about 0.8 km in Banli area and between Jiuchongshan and Dalan village about 1.00 km in Jiuchongshan area were high traffic accident and high frequency crossing of T.leucocephalus because Jiuchongshan Area and Banli Area were centralized habitats;(2)Due to the increase in population,the minimum groups of T.leucocephalus have been exceeded or reached in Jiuchongshan area and Banli area which in the north of the national highway G322.One male and multiple female reproductive strategies and fields protect social attributes,causing T.leucocephalus to frequently cross roads;(3)It is recommended to build animal passages,set speed bumps and interval speed,construct ecological corridors,establish small nature reserve,improve environmental requirements,advance protection legislation,formulate the protection plan,integrate regional greening project,and carry out the reconstruction corridor of T.leucocephalus.
