| Abstract: | The study of relationships between species distribution patterns and environmental variables is of great significance to the planning of ecological corridors and environmental restoration.We collected 51 distribution points of Trachypithecus leucocephalus and 11 environmental variables in the National Nature Reserve of the white-headed langur in Chongzuo,Guangxi.This paper makes a comprehensive evaluation of habitat suitability by using maximum entropy modeling,which generated habitat suitability indices through threshold delimitation.We delimited low-suitability area,suitable area and highly-suitable area,which covered 5 061.43 km~2,42.80 km~2 and 20.63 km~2 respectively.The analysis of environmental variables showed that the comprehensive contribution values of annual precipitation,land use classification,slope and annual average temperature were 54.6%,17.4%,11.8% and 9.5% respectively.The cumulative contribution value of those four environmental variables was 93.3%,suggesting that these factors had greatest effect on the distribution of white headed langurs.In order to effectively protect the white-headed langur and its habitat,we suggest planning ecological corridors within the reserve in order to expand the suitable habitat into the restoration area and promote intergroup gene exchange between the langurs. |
