摘　　要：以沂山油松为样本,建立油松标准化年表,在此基础上分析年轮宽度与气候因子的关系.结果表明:当年5月份平均气温和平均最高温都与油松年表呈显著负相关(P<0.05),而当年6月份平均气温和平均最高温都与油松年表呈极显著负相关(P<0.01);当年7月份降水量与油松生长呈显著正相关(P<0.05);当年5-6月平均相对湿度与油松年表呈显著正相关(P<0.05),且当年8-10月平均相对湿度与油松年表呈极显著正相关(P<0.01).研究表明,在本地区树木生长季内,降水越多,气温越低,越促进树木生长.Taking pine tree in Yishan mountain as a simple, we establish the tree ring width standard chronology, and analyse the relationship between the tree ring width and the climate factor. The results showed that the pine tree ring width chronology had significant negative correlations with the average temperature and the average maximum temperature in May of that year （ P 〈 0.05 ） , and significant negative correlations were observed between the pine tree ring width chronology and the average temperature and the average maximum temperature in June of that year （ P 〈 0.01 ）. The precipitation in July of that year had a significant positive correlation with the growth of pine tree （ P 〈 0.05 ）. The tree ring width chronology had significant positive correlations with the average relative humidity in May - June of that year （ P 〈 0. 05 ）. Besides, significant positive correlations were observed between the pine tree ring width chronology and the average relative humidity in August - October of that year （ P 〈0.01 ）. Our study indicates that more precipitation and lower temperature can promote the tree growth.
