摘要:

目的 研究青海省海东地区鼠类种群特征。方法 采用夹夜法,按不同生境调查海东地区鼠类,对生态学资料进行数据分析。结果 在海东地区共捕获鼠类427只,隶属2目6科15种,其中在针阔混交林捕获鼠类7种82只,捕获率3.90%;林缘灌丛捕获鼠类6种112只,捕获率 4.53%;高山灌丛捕获鼠类7种77只,捕获率3.35%;高山草原捕获鼠类7种95只,捕获率2.94%;农田居民区捕获鼠类9种61只,捕获率2.60%;高山草原中的生物量最高,为35.95;林缘灌丛次之,为34.70;高山灌丛最低,为21.59;小家鼠及褐家鼠的肥满度在农田居民区中最高,为5.18和4.05;长尾仓鼠在高山草原中的肥满度最高,为3.80;大林姬鼠在林缘灌丛中的肥满度最高,为2.97。同一鼠种在不同生境中的生物量、肥满度各有其特点和差异。结论 青海省海东地区鼠类区系构成较为混杂,降低优势害鼠的种群密度,防止鼠害发生是今后工作的重点。

Abstract:

Objective To investigate the faunal characteristics of rodent community in Haidong area of Qinghai province. Methods The night trap method was used to determine the quantity of rodent populations at different habitats in this area as the basis for ecological analysis. Results A total of 427 rodents were captured in Haidong area, which belonged to 15 species, 6 families and 2 orders, including 82 rodents of 7 species in mixed conifer forests with a capture rate of 3.90%; 112 rodents of 6 species in forest edge scrubs with a capture rate of 4.53%; 77 rodents of 7 species in alpine shrubs with a capture rate of 3.35%; 95 rodents of 7 species in alpine grasslands with a capture rate of 2.94%; and 61 rodents of 9 species in residential farmlands with a capture rate of 2.60%. The highest biomass (35.95) of rodent community was observed in alpine grasslands, followed by that in forest edge scrubs (34.70) and lowest in alpine shrubs (21.59). The fatness of Mus musculus and Rattus norvegicus peaked in residential farmlands at 5.18 and 4.05, respectively; the fatness of Cricetulus longicaudatus peaked in alpine grasslands at 3.80; and the fatness of Apodemus peninsulae peaked in forest edge scrubs at 2.97. The biomass and fatness of one species varied and diversified in characteristics at different habitats. Conclusion The faunal composition of rodent populations is complicated in Haidong area of Qinghai province. Upcoming anti-rodent work should be focused on reducing the density of predominant species and preventing the occurrence of rodent infestation.
