摘要:

  【摘要】 目的 掌握乐山市“三江”河漫滩鼠形动物的群落结构组成及其数量变动规律,为相关部门评估鼠患及科学指导灭鼠提供依据。方法 于2007年9月至2008年8月沿“三江”河漫滩布置固定的样线,采用夹夜法逐月采集标本,经分类鉴定,统计捕获率,并解剖观察鼠形动物的繁殖状况。结果 乐山市“三江”河漫滩鼠形动物的群落结构组成为“微尾鼩+黑线姬鼠+山东小麝鼩+褐家鼠”,其中微尾鼩(49.55%)和黑线姬鼠(45.34%)为优势种,山东小麝鼩(3.60%)为普通种,褐家鼠(0.90%)为稀有种。从全年来看,鼠形动物的数量变动主要有2个高峰期,即7月和10月,其中7月的峰值显著高于10月,冬春两季基本维持在一个较低的数量水平,于6月开始迅速回升。2个优势种的数量变动也基本符合这一规律。结论 微尾鼩和黑线姬鼠是主要的防治对象,应采取多种措施,标本兼治。

Abstract:

  【Abstract】 Objective To grasp the community structure and quantity fluctuation of rat?shape mammals and provide the scientific basis for the evaluation and control of the mammals. Methods Rat?shape mammals were captured by night trapping method along the washland of the “Three?rivers” in Leshan city from September 2007 to August 2008. Results There were four species of rate?shape mammals. Among them, Anourosorex squamipes(49.55%) and Apodernus agrarius(45.34%) were the dominant species, Crocidura shantungensis(3.60%) was the common species, and Rattus norvegicus(0.90%) was the rare species. Seen from the quantity fluctuation of rat?shape mammals, there were two peaks in the whole year. One was in July and the other was October, but the peak value of the former was prominently higher than the latter. In winter and spring, the quantity basically maintained a lower level. And then, it began to go up quickly in June. By and large, the quantity fluctuation of the two dominant species also accorded with the rule.  Conclusion  An.squamipes and Ap.agrarius were the main targets to prevent and control.
