利用趋势倾向率等统计分析方法,对内蒙古气候(1961-2006年)和小叶杨叶芽开放期(1981-206年)的变化趋势进行了分析,并探讨小叶杨叶芽开放期与不同时段的气温、降水、日照的相关性以及气候因子的综合作用.分析发现:内蒙古地区小叶杨叶芽开放期变化趋势表现出强烈的地域差异.小叶杨平均叶芽开放期孪井滩最早,鄂温克最晚,两地相差39 d;各地区小叶杨叶芽开放期的变化趋势基本一致,除额尔古纳呈提前趋势外,其他地区表现出延迟趋势;小叶杨叶芽开放期与春季气温均呈显著负相关,即春季气温升高,小叶杨叶芽开放期提前,与降水和日照的相关性不显著;在日照充足的内蒙古地区气温和降水共同影响着小叶杨叶芽开放期的变化.

With the help of statistical analysis, the changing trends between climate data from 1961 to 2006 and bud opening of Populus simonii cart. (1981-2006) were analyzed in the Inner Mongolia. Moreover, the relationships among bud opening and air temperature, precipitation and solar radiation as well as the comprehensive effects of climate factors were discussed. The results showed that there are significant regional differences. The difference of bud opening between the earliest (Luanjingtan) and the latest (Ewenki) region could be 39 days. There is a similar changing pattern in different regions with prolonged trend except Ergun, which shows an advanced trend. There is a significant negative relationship between bud opening and spring temperature. However, there are no obvious relationships between the opening and precipitation and sunlight. The air temperature and precipitation are interactive factors influencing the bud opening in the Inner Mongolia with abundant sunshine duration.
