| 摘 要： | 应用聚集度指标检验、线性回归方程检验,研究探讨了侧多食跗线螨混合种群的空间分布型。结果表明,侧多食跗线螨在辣椒田呈聚集分布,这种分布主要是由该螨的生物学特性决定的,且具有密度依赖性。在回归检验中,3种回归模型的拟合效果良好,但以Taylor（1961）的幂法则最优。 |

| Abstract: | The spatial distribution patlern on Polyphotarsonemus latus mixed population was studied by the aggregaton index testing and linear regression gquation test.The results showed that the Polyphotarsonemus latus was aggregated distribution in popper field.This distribution was maily determined by the biological characteristics of the mites and was density-dependent.Three regression model fit well and the optimal power law of Taylor(1961)was the best in regresstion test. |
| Keywords: | pepper fields Polyphagotarsonemus latus spatial distribution accumulation index linear regression |
