Abstract: To determine a reasonable density for cultivating and managing forests,stand density,an important element for controlling growth characteristics and for determining the impact on growth laws,was studied. Young Pinus tabulaeformis with six stand densities(1 050,1 850,2 355,3 825,5 133,and 5 533 stemshm-2) and stand ages of 10,15,20,and 25 years with the same growing conditions in the Miyun Reservoir of Beijing were measured. Results showed that density had a strong negative relationship to diameter at breast height (DBH)(r = - 0.757,P<0.01) and volume of timber(r = - 0.618,P<0.01),had a negative relationship to height(r = - 0.479,P<0.05),and had no negative relationship to stock volume. Overall,there were positive relationships between forest age and growth indicators(P<0.01). According to growth indicators and plant production,a stand density of 1 800 - 2 300 stemshm-2 was suggested.[Ch,4 fig. 2 tab. 12 ref.]
