采用扩散系数C、聚集度指标I、Cassie R.M.指标CA、森下正明扩散指标Iδ、Lloyd M.的聚块性指标L、Iwao的m—m回归分析法和Taylor的幕指数法等7种方法测定了刺槐谷蛾第1代幼虫种群空间分布型,并探讨了其在最适抽样、资料代换及序贯抽样中的应用。
The diffusion coefficient C, aggregation index I, Cassie RM index CA, Morimoto Masaaki diffusion index Iδ, Lloyd M.’s conglomerate index L, Iwao’s m-m regression analysis method and Taylor’s curtain index method were used to determine The spatial distribution patterns of the first generation larvae of Acacia crassipes were discussed, and their application in optimal sampling, data substitution and sequential sampling were discussed.
