| 摘 要： | 为了调查灾后北川村庄小兽种群动态变化,掌握小兽种群数量及变化规律,防止灾后兽害及自然疫源性疾病爆发.从2010年1月至2011年7月,每季度采用夹夜法对北川村庄进行小兽种群动态调查.整个调查期间捕获小兽176只,分属2目2科3属4种,捕获率为10.88％,其中四川短尾鼦为优势种,占捕获数的94.89％.调查期间,小兽种群数量在2010年10月为最高峰,每年4、7月为其繁殖高峰期,雌体怀孕率为41.56％,平均胎仔数为4.16个,雄体睾丸下降率为69.89％.不同季节、不同年度间小兽种群数量存在差异,可能受栖息环境改变及季节、气候、食物等因素影响.

| Abstract: | To investigate the population dynamics of small mammals in Beichuan residential areas and master population quantity and change rules of small mammals for preventing small mammals population and natural focal diseases outbreak.The night trapping was used for the investigation into small mammals population dynamics in Beichun residential areas from January 2010 to July 2011 every three months.A total of 176 individuals which belonged to 2 order 2 family 3 genus 4 species were captured and capture ratio was 1... |
