| Abstract: | Using methods of aggregation index determination, linear regression equation and spatial frequency distribution, spatial distribution patterns ofAphrodisium gibbicolleLarvae was studied. The results showed spatial distribution patterns ofAphrodisium gibbicolleLarvae was negative binomial distribution.Based on this, by usingM＊ -mregression equation of Iwao, under allowed error range of the 0.05, 0.1 and 0.2the optimal sampling number was calculated. |
