Distribution And Conservation Of Mammal Resources Of Pingheliang Provincial Natural Reserve In Shaaxi Province

Shannxi Pingheliang Provincial Nature Reserve located in the southern slope of eastern section of the Qinling Mountains is approved by Shaanxi Provincial People's Government and established in October in 2006 after implementing the project of totally banning the natural forest logging and reserving the natural resource.This area,as an important component of the Nature Reserve group in the Qinling and the east distribution area of Chinese pandas,aims to protect precious rare animals and their habitats,which plays a very important strategic role in strengthening the comprehensive protection of biodiversity in Qinling.Due to the severe shortage of data about animal resources after Nature Reserve established,the management and development has been limited.In view of this actual situation,this paper emphatically made an investigation on mammal resources of Shannxi PingHeliang Provincial Nature Reserve.Based on the previous results and combined with field survey data,the writer found out the mammal resources,fauna and distribution of Shannxi PingHeliang Provincial Nature Reserve by inducing analyzing and summarizing,also proposed countermeasure of biodiversity protection in nature reserve.The main results were as follows:1.According to related literature and the field survey data,there are totally 85 mammal species in the PingHeliang Provincial Nature Reserve,subordinating to 7 orders,26 families and 64 genera,which is about 50.898%in the 167 mammal species of Shannxi province.The floristic characteristics of these mammals mainly show the predomination of oriental region species,the diversity of geographical distribution,and the significantly ancient and remain characteristics of some group.2.The floristic elements are complicated and various,there are more southern types in all species.The families composition of mammal fauna in the PingHeliang Provincial Nature Reserve are mainly representative families in Subtropical Regions of South.,while only a few Holo-Arctic species belonging to North types.The proper oriental genus which has remain characteristic is the giant panda family.3.There are some the typical south,north types and plentiful carnivore species in mammal geographical distribution of Shannxi PingHeliang Provincial Nature Reserve.It shows that recent fauna are ancient and relict.4.In the mammal fauna of Shannxi PingHeliang Provincial Nature Reserve,the endemic species are more abundant,about 45.88%in the total species of mammals,especially the state and the Shannxi province protection species,as well as species which are beneficial or have important economic value and scientific interest.5.As the increasing of elevation,the mammalian species number is evident differences in vertical zones.In the different range of vertical zone,oriental region species account for the greater advantage(57.14%-70.59%);The percentage of Palaearctic region did not change significantly(17.65%-28.57%) with the increase of altitude down to 2300 m,while The percentage of dispersed species showed decreasing trend(17.65%-28.57%).The results indicate that the adaptation of dispersed species to cold alpine environment gradually weakened.6.There is 13 species of rare protective mammals in Shannxi PingHeliang Provincial Nature Reserve,the animals inhabited in a narrow range and have less population.In the area the quantity of goral,black bear is relative larger,takin,yellowlhroated marten took second place,and the rest 8 species are less.7.Ecological distribution character of small mammals in Shannxi PingHeliang Provincial Nature Reserve is:12 genera and 15 species are collected in deciduous broad-leaved forest zone(1064-1500 m),9 genera and 11 species are collected in Pinus-Quercus forest zone (1500-1900 m) as well as 14 genera and 21 species in Brich-Spruce forest zone(1900-2482 m).
