摘要
对金华北山社鼠肥满度的研究表明 ,社鼠肥满度有明显的季节变化 ,4月～ 5月、7月～ 9月和 1 1月～1 2月分别为肥满度高峰期 ;6月、1 0月和 2月肥满度显著下降 .社鼠肥满度与气候因子中的气温、地下 3 0 cm土层温度成显著性相关 ,与降雨量成负相关 .
The relative fatness of Rattus niviventer showed obvious seasonal changes and three peaks in April to May, July to September and November to December,and lowered obviously in June, October and February.The relative fatness of Rattus niviventer was significantly positive correlative with air temperature and underground temperature,and negative correlative with precipitation.
