| 摘 要： | 本文报道了七星瓢虫的空间分布调查结果。通过分析,七星瓢虫在包菜地内的空间分布属聚集分布,最适于Poisson-binomial分布,其次适于负二项分布和核心分布,不适于Poisson分布。但就本调查结果而言,七星瓢虫在包菜地的聚集行为可能是由于环境而引起的。分析结果还表明,七星瓢虫种群扩散亦属于聚集型扩散。

| Abstract: | Based on the analysis of the data obtained from the survey of Brassica pekinensis in the field, it is determined that the spatial distribution pattern of Coccinella septempunctata is aggregation pattern, and fits to poisson-binomial distribution pattern best. And it is possible the aggregation bebavor of Coccinella septempunctata is caused by the environmental factors. In addition, the results of analysis express that the dispeosirn of the population of C. septempunctata is aggregation pattern. |
