| Abstract: | In order to study the diameter structure regularity of natural Pinus tabulae formis forest in Huanglongshan forest area,the authors set up 4 plots of 0.2 hm~2 sample plot in demonstrative area of Caijiachuan forest farm in Huanglongshan forest area in Shanxi province.All indicators were actually measured and the diameter structure was imitated by the application of Weibull distribution function and Maiyiefu Index distribution function.Furthermore stand species composition in research site and diameter structure regularity were also studied. |
