摘要
本文应用lwao和Taylo’s回归模型以及 6个聚集度指标 (C、CA、m 、m /m、I、K) ,对麻园苎麻天牛幼虫空间分布型进行了研究。测定结果属聚集分布 ,为田间调查及防治提供了依据。
The author used Iwao and Taylor's regression models and edlected 6 indexes of aggregation (C?C A?m *?m */m?I?K)to analyze distribution of ramie lonicrn larvae in the broad ramie.The result that the distribution of ramie longicorn larvae was the aggregated distribution pattern.It will provid the basis for field sampling and control.
