A Study on Summer Birds and Their Community Structures in Pingheliang Nature Reserve

Avian field survey was carried out in Pingheliang Nature Reserve in Shanxi province from July to August of 2009.A total of 100 species were recorded,including to 41 families,13 orders.Among all the birds,6 species birds are listed as rank Ⅱ species in the name list of National Protected Wildlife.In terms of geographical distribution,there were 33 palaearctic species,50 oriental species,17 cosmopolitan species.Migrants have a lower rate at 30.0%(30 species) of all the birds,and the others are residents(70 species,70.0%).Through analysis,the data of research(dominant species: 10 species;frequent species: 14 species;seldom species: 49 species;rare species: 27 species) show the avian conservation and management should be strengthened in Pingheliang Nature Reserve,for the comparatively high percent of species are in possible danger of survival.Among the four communities,the forest community has the most richness of birds,because it has the most quantity and number of species,and the greatest rate of resident bird species.Due to the smallest richness,diversity and evenness indexes,in despite of the greatest rate of immigrants,water area community has the least avian diversity.Birds of water area community are basically lived on water,but the others mainly live in terrestrial,so there are smaller likeness coefficients of birds between water area community and the other three communities.However,the trend of human interference in the region is increasing,so it is necessary for people to grasp the living conditions of birds accurately through a long-term monitoring and systematic biology research that can be the scientific basis for relevant functional departments to formulate policies and measures to protect them better.
