Abstract:
Objective To investigate the community structure and spatial distribution of wild myomorpha in the plague foci of Lianghe County,Yunnan Province.Methods From December 2015 to October 2016,in Mangdong,Hexi,Nangsong and other places in Lianghe County,forest landscape samples were randomly selected in different altitude gradients (1 000 ～,1 200 ～,1 400 ～,≥ 1 600 m).Peanut was used as a bait for trapping myomorpha,and the community structure of myomorpha was analyzed.Results A total of 663 myomorpha were collected and the density was 7.97％ (663/8 320),which were divided into 16 species,11 genus,5 families,and 3 orders.Rattus tanezumi (30.62％,203/663) was the dominant species.In the 1 000-＜ 1 200 m altitude gradient,the richness of myomorpha was the highest (13 kinds).In the 1 400-＜ 1 600 m altitude gradient,the index of diversity (2.094 2) was the highest.With the increase of altitude,the ecological dominance were increased,and the values were 0.672 2,0.774 2,0.842 8,and 0.882 4,respectively,whereas the evenness presented a decreasing trend,and the values were 0.269 2,0.197 1,0.142 8,and 0.162 0.Conclusions The Rattus tanezumi has presented a single dominant distribution at different elevation and the number and the species of the wild rodent with superior position have increased with the altitude increased in Lianghe focus.With the increase of altitude,the diversity and the evenness have increased,whereas the richness and the dominance have decreased.
