Abstract: Work on the relationship between the human migration and the small mammal community has been carried out in the reclaimed area of Qiantang River in August of 1987 and 1989.This paper presented some of the results of this work. 1.There were suncus．Rattus norvegicus， Mus musculus and Crocidura dracula in different residential areas．suncus murinuswas the dominant population in domestic of the small mammal community．
2.The small mammal in domestic community in the reclaimed area can be divided into 5 community types．
3.The adaptability of the do mestic rodent was higher than that of the insectivora in seasonal human migration during the early reclaimed period, but the number of insectivora was more than that of rodent with the increasing of human and building．
4.There was no marked correlation between the population densities of the small mammals in domestic，but there was negative correlation between the population densities of the domestic redent and that of the insectivora．The relationship between the small mammal community in domestic and field has also been discussed in this paper．

Key words: Reclaimed area, Small mammal, Community structure

摘要： 1987年8月和1989年8月，作者对钱塘江河口滩涂围垦区人口迁居与农田小兽群落的关系进行了调查。在6种类型的人群居住区内，4种家栖小兽中以臭胸为优势种。随着人口和建筑物增多，食虫类数量超过家鼠，处于优势地位，因而在家鼠与食虫类之间有一定程度的负相关。同时还探讨了家牺小兽群落与农田小兽群落之间的迁移和扩散的关系。
