In the stand growth model,selection of the stand diameter distribution functions is crucial.In this paper the diameter of Avicennia Marina in Leizhou Peninsula was used as the research object.The resulting data skewness and kurtosis were used as indicators,and three kinds of probability density function parameters of normal distribution,Weibull distribution and Gamma distribution were used for fit testing and analysis of the Avicennia Marina diameter distribution characteristics.The results showed that the Avicennia marina population is distributed in small and midium diameters in Leizhou Peninsula and the skewness and kurtosis are greater than 0,diameter distribution curve is left skewness,distribution curve is steep,showing peak state.Normal distribution and Weibull distribution fitting effect is poor,and Gamma distribution is fitted with good results.Through the establishment of Gamma distribution parameter estimation equation each diameter class and its dynamics can bepredicted.The result provides reference for the management and utilization of Avicennia marina community in Leizhou Peninsula.
