常熟尚湖周边农田土壤弹尾类的分布特征研究

Study on the Distribution Features of Collembola in the Surrounding Farmlands of Shanghu in Changshu

调查分析了常熟尚湖周边农田土壤弹尾类的分布特征,结果表明,土壤弹尾类的垂直分布具有极其显著的表聚性。其季节消长特征是从冬季到夏季土壤弹尾类平均密度呈现逐渐下降趋势,而由夏季到冬季弹尾类的平均密度则有较明显的上升过程。土壤温度与弹尾类种群密度呈负相关关系,而土壤湿度与弹尾类种群密度具有正相关性。

The distribution features of Collembola in the surrounding farmland of Shanghu in Changshu were investigated and analyzed. Results showed that the vertical distribution of Collembola presented extremely significant congregation on the surface. The average density of soil Collembola decreased gradually from winter to summer,while increased obviously from summer to winter. The population density of Collembola is negatively correlated with soil temperature,while positively correlated with soil humidity.
