| 摘 要： | 采用6种空间分布模型、理论抽样法以及序贯抽样法等对油桐尺蠖幼虫的空间分布情况进行了详细研究。结果表明：油桐尺蠖幼虫的空间分布型为聚集分布,聚集的原因可能是由环境因子作用所造成。同时建立了理论抽样模型：N=t2（2.4360/m＋0.4766）/D2以及序贯抽样模型：T（n）=5n±（12.1799n＋11.9144）1/2,以期为油桐尺蠖的测报和防治工作提供理论依据。

| Abstract: | The spatial distribution pattern of Buzura suppressaria＇s larvae was examined by 6 aggregation indices,regression analysis methods of Iwao and Sampling technology.The results showed that Buzura suppressaria larvae was in aggregative distribution and the aggregation was caused by the environmental factors.The optimum theoretical sampling number was established.The model was as follows： N=t2（2.4360/m＋0.4766）/D2 and the sequential sampling： T（n）=5n±（12.1799n＋11.9144）1/2.It provided the base for sampling and forecasting of Buzura suppressaria. |
