| 摘 要： | 应用聚集度指标检验、线性回归方程检验方法研究探讨了灰巴蜗牛在三叶草田垂直方向和水平方向的空间格局。结果表明,灰巴蜗牛在垂直方向和水平方向的空间格局均为聚集分布,这种聚集是由灰巴蜗牛本身行为和不同生境决定的。并应用Iwao的m＊-m回归式计算在允许误差范围内的理论抽样数。

| Abstract: | The spatial pattern in vertical and horizontal directions of Bradybaena ravida in clover field was studied by the aggregation indices and liner regression analysis.The results showed that the spatial pattern belonged to the aggregated distribution in vertical and horizontal directions.The aggregated distribution was caused by both the biological characteristics of Bradybaena ravida and the different habitats.The theoretical sampling number within the allowable error was calculated by the m*-m regression for... |
