| Abstract: | There are three ages of Pinus koraiensis fruit forest after thinning which is 15years old,25years old and 35 years old,three different reserve densities,three repeated samples and seed yielding quantity of these trees was inspected during the 5 years continually.Based on the investigated data,the management density of Pinus koraiensis fruit forest in different ages and diameter grades was obtained using variance analysis. |
