Abstract: Taking the broad-leaved pine forest in Jiaohe, Jilin as the research object, the sample plot area of 30 hm~2 was divided into continuous sampling units of 5 m×5 m, 10 m×10 m, 20 m×20 m and 25 m×25 m. The samples of each species in each sampling unit were counted under four different scales to obtain the number of sampling units of each species in different scales. The random distribution model and negative binomial distribution model were used to analyze the species abundance distribution, and t... More
