| 摘 要： | 以北京地区17年生银杏为试材，研究了气温和降水对银杏木材年轮宽度、年轮密度，最大密度、最小密度的影响。结果表明，不同月份的气温和降水，对银杏生长有不同程度的影响。如生长季节中的7月份气温与年轮宽度有－0．44的负相关，对木材密度影响不大；而月份降水量与年轮宽度呈0．69的正相关，在0．01水平相关显著，8月份降水量与年轮密度、最大密度和最小密度呈0．70、0．74和0．74的正相关关系，在0．01水平相关显著。

| Abstract: | Taking 17 year old Ginkgo biloba as test material, the effects of temperature and precipitation on wood ring width, ring density maximum density and minimum density were studied. The results showed that the temperature and precipitation in different months had different influence on the growth of G. biloba. The precipitation in July was positively correlated with ring width with a coefficient of 0.69, the significant level is 0.01. The precipitation in August was positively correlated with ring density, maximum density and minimum density with the coefficients of 0.70, 0.74 and 0.74 respectively in the level of 0.01. |
