摘要/Abstract

摘要： 本文根据黔西北地区农田鼠类的种类组成和数量，将该地区农田鼠类划分为如下4个鼠类群落：A.高山蛭鼠+社鼠群落．B.黑线姬鼠+锅金小家鼠+高山蛭鼠群落，C.黑线姬鼠+大足鼠+锡金小家鼠群落和D.黑线姬鼠+小家鼠群落。在群落B中多样性指数(1．433)和均匀性指数(0．089)最高．最低是群落A，分别为0.889和0.457，最高的优势度指数(0．505)是群落A，而群落B是0.303为最低，群落B和群落C之间的相似性指(0.750)
最高，群落A和群落D之间是0.075为最低。

Abstract: The farmland rodents in the northwest region of Guizhoou were investiseted from January to December 1990.A total of 787 the individuals of rodents were captured.According to the species and number of the captured rodents， it can be devided into four type of rodent communities.
A.Apodemus chevrieri+ Niviveater confucianus community.
B.Apodemus agrarius+ Mus pakari+Apedemus chevrieri community C Apodemusagrrarius+ Rattus nitidus+ Mus pahari community. D.Apodemus agrrarius+ Musmustangs community. The indexes of diversity， evenness and dominance were diferent in different cornmunities.The highest index of diversity and evenness were found in connunity B ，and the lowest in community A .The highest dominance index was shown in community A,and the lowest in community B． The similarity index between communiy B and C was the highest，and the lowest between community A and D.There were month variations of rodent composition in different communities
