Fractal Characteristics of Root System,Tree Height and DBH of Choerospondias axillaris;

Simulating to Weibull Distribution of DBH and Height of Artificial Stand of Alnus cremastogyne;

Analysison Relationship Between Height and Diameter at Breast Height of Main Mangroves in Dongzhai Harbour,Hainan Island;

Study on the model between height and diameter at breast height of Metasequoia glyptostroboides in Shanghai

Relationships between diameter at breast height and cone/seed character of Pinus thunbergii population in Yantai coastal protection forest

Taking Guangxi Standard Standing Volume Formula as a basis,electric volume table about the main timer tree species has been made with VB programming language,with which you just need to input the values of diameter at breast height(DBH) and tree height rather than table checking or manual computation,and then you can obtain the corresponding timber volume value.

Regression equations among the leaf area index(LAI),bamboo stock diameter at breast height(DBH),density of bamboo plantation and the number of branch strata were set,and it was discovered that there were close correlations among these indices.

tree height by adopting the regression equation based on the diameter breast height of fallen C.

Regression analysis between rhizome and dbh of main tree species in nataral forests in North Shaanxi and significat tests on the regression models showed that there was a close straight regression between the rhizame and dbh,definite function existed between the rhizome and dbh,and the established.
