摘要: 长江中下游平原及华北平原是黄鼬(Mustela Sibirica)的主要产区,在黄土高原地区的数量则较为稀少。为了掌握黄鼬对繁殖环境的选择和各地资源状况,达到合理利用黄鼬资源的目的,我们选择长江流域的崇明岛,淮河流域的宿县,黄河流域的衡水县及黄土高原的太原、交城进行调查。调查期间,得到上海市畜产公司、山西省和太原市畜产公司、衡水地区畜产公司及宿县地区畜产站的热情支持。

Abstract: During late May to end of June 1978, an investigation was made to as -certain the environment preference of nesting and nest density of female weasel during reproductive season. The study areas included Chongming Island in Lower-Yangtse Plain, Xiu county of Huai River Basin,Hengshui co -unty in the Yellow River Basin,Taiyuan and Jiaochen county of the Loess PlateauHunting dogs were used to search out the nest sites and the nest were examined.Of all the nests investigated, the higest nest density was found in the abundant water source ( peddy areas ) environment.For example, on Chongming Island there were up to 1.7 nest per km2.In dry regions such as wheat farming areas of the Huanghai-Huaihe Plain the nest density was 0.6 nest per km2. In dry crop farming of the Loess plateau areas the density were only 0.2 nest per km2.Among various environments the weasels mainly selected hay for producing and rearing their young. An analysis of 40 nests. 85%were in haystacks and haymows, 7.5%were found among graves, 5% were found in stone piles and 2.5% were found in crevices in houses.The characteristics of nesting environment preference and rearing habits of the females suggests that it would be wise to pile haystack in the field to attract weasels in order to develop weasel resouree, in severe rodent infection areas the attraction could act as a biological control.
