摘  要：
选取九连山国家级自然保护区气象观测站1982-2014年逐日气象资料,统计分析九连山亚热带常绿阔叶林区的平均气温、降雨量、相对湿度及蒸发量等变化特征,并用5 d滑动平均法分析九连山常绿阔叶林区四季变化特征,更好地反映当地的气候寒暖和符合农、林业生产的要求。分析显示,九连山常绿阔叶林区的年平均气温为16.8℃,极端最低温-7.4℃,极端最高温37℃,年平均相对湿度为86%,年均降雨量1 927.7 mm,年均蒸发量793.4 mm。春季开始的平均时间为3月21日,平均持续天数为81 d;夏季开始的平均时间为6月10日,平均持续天数为94 d;秋季开始的平均时间为9月12日,平均持续天数为73 d;冬季开始的平均时间为11月24日,平均持续天数为117 d。

摘  要：
Selected the daily meteorological data during 1982-2014 from Jiulianshan National Nature Reserve Meteorological Station, statistically analyzed the change characteristics of the average air temperature, rainfall, relative humidity and evaporation in the subtropical evergreen broad leaved forests in Jiulianshan mountain. The change characteristics of the four seasons of the evergreen broad-leaved forests in Jiulianshan mountain were analyzed with 5 d sliding average method in order to better reflect variations of the local climate and meet the requirements of agricultural and forestry production. The analysis showed that the annual average air temperature of Jiulianshan mountain evergreen broad-leaved forests is 16.8 ℃, the extremely low temperature is-7.4 ℃, the most extreme high temperature is 37 ℃, the annual average relative humidity is 86%, the annual rainfall is 1 927.7 mm,the annual evaporation is 793.4 mm. The average time of beginning of spring is March 21, the average duration was 81 d. The average time of beginning of summer is June 10, the average duration was 94 d. The average time of beginning of autumn is September 12, the average duration was 73 d. The average time of beginning of winter is November 24, the average duration was117 d.
