通过调查41株榆林市榆阳区内生长的樟子松,发现胸径/地径比值相对恒定,数值是0.70倍左右,其范围在0.67～0.75之间,胸径、地径基本同步加粗。树高/地径比值总体呈现出树越粗、树高/地径比值越小的规律,最大值是46.27倍,最小值是31.72倍,树高的生长量随树木的加粗呈现出放缓的规律。

Through investigating 41 strains of Pinus sylvestris var. mongolica Litv. planted in Yuyang District, Yulin, the results show that the ratio of diameter to ground diameter keeps constant relatively with the value at 0. 7 times and the range from 0. 67 to 0. 75, and diameter and ground diameter overstrike synchronously. The ratio of height to ground diameter shows the law that the bigger the dianmeter is, the smaller the ratio of height ro ground diameter is, with the maximum value of 46. 27 times and the minimum value of 31.72 times. And the height is opposite to the overstriking of trees. growth
