应用多个聚集度指标和Iwao、Talor回归分析法对野果林苹果小吉丁幼虫空间分布型进行研究。结果表明:苹果小吉丁幼虫空间分布型为聚集分布,同时对最适抽样数及序贯抽样进行了研究。 Spatial distribution patterns of apple jellyfish larvae in apple trees were studied using multiple aggregation indexes and Iwao, Talor regression analysis. The results showed that the spatial distribution of apple jelly larvae was aggregated distribution, and the optimal sampling number and sequential sampling were studied.
