白头叶猴是中国野生动物保护法中的一类物种。仅分布于广西南部的龙州、宁明、崇左、扶绥四县的喀斯特丘陵地带。其南、西、北方界以岷江、左江为界，东界以十万大山为界。20世纪80年代进行的种群调查表明，广西共有630只，其中龙州、宁明两县244只，崇左县6个片区117只，扶绥县9个斑块272只。经本课题组和广西林业局调查，目前在上述四县仍有白头叶猴580-620只，其中龙州、宁明有210-240只，崇左有90-100只，扶绥有250只。根据我们的统计，只有约200平方公里的栖息地仍然在白头叶猴的现有范围内，这是分离为13个乡镇的16个补丁。龙州县的上津、响水和宁明县的亭梁、驼路是最大的斑块，总面积为68 km 2;崇左县和扶绥县的生境破碎化程度很高，崇左县有6个斑块，总面积为43.5km2，扶绥县有9个斑块，总面积为88 km 2。目前，尽管政府已经做出了许多努力来保护这一濒危物种，例如将其列为I类保护物种并指定自然保护区和站点，但白头叶猴仍然遭受严重的栖息地恶化和人为干扰，如种植，砍树烧柴和偷猎。(C)2002爱思唯尔科技有限公司版权所有。
The white-headed langur is classed as a category I species under the Wild Animal Protection Law in China. It is distributed only in Karst hills in four counties (Longzhou, Ningming, Chongzuo and Fusui), in the southern Guangxi province of China. The Mingjiang River and the Zuojiang Fiver form its southern, western and northern boundaries, and the Shiwandashan Mountains restrict its range in the east. Population surveys conducted in the 1980s showed that there were a total of 630 individuals in Guangxi, including 244 in Longzhou and Ningming counties, 117 in six fragments of Chongzuo County and 272 in nine patches of Fusui County. Surveys conducted by our group and Guangxi Forestry Bureau indicated that a total of 580-620 white-headed langurs still live in the above four counties, including 210-240 in Longzhou and Ningming, 90-100 in Chongzuo and 250 in Fusui. According to our statistics, only about 200 km 2 of habitat remains within the current range of the white-headed langur and this is separated as a total of 16 patches in 13 townships. Shangjin and Xiangshui in Longzhou county and Tingliang and Tuolu in Ningming, form the largest patch of the range, with total area of 68 km(2), while in Chongzuo and Fusui County, the habitat is heavily fragmented with six patches of 43.5 km(2) in Chongzuo and nine patches of 88 km(2) in Fusui. At present, the white-headed langur is still suffering from heavy habitat deterioration and human disturbance such as cultivation, tree-cutting for firewood, and poachings even though the government has made many efforts to protect this endangered species, such as putting it as a category I species for protection and designating the nature reserve and stations.
