摘　　要：以荔波瘤果茶树木年轮作样本,运用树木年轮气候学的方法,分析了树木年轮宽度与气温、降雨量和相对湿度之间的关系。结果表明:1)荔波瘤果茶生长对气候变化十分敏感;2)荔波瘤果茶年轮宽度与当年年平均气温和前一年年平均气温均为负相关,与当年4-9月平均气温极显著负相关;与当年3-11月的月平均气温负相关,与1月、2月、12月的月平均气温正相关,与前一年2月、8月、9月、12月的月平均气温正相关,其他月份均为负相关;3)荔波瘤果茶年轮宽度与当年的年降雨量呈极显著正相关,与前一年的年降雨量亦呈正相关;与当年4-9月降雨量呈极显著正相关,与前一年4-9月降雨量亦呈正相关;与当年5月、11月降雨量呈负相关,其余月份均为正相关;与前一年的1月、2月、4月、11月、12月降雨量呈负相关,与其他月份呈正相关;4)荔波瘤果茶年轮宽度与当年的年平均相对湿度呈极显著正相关,与前一年的年平均相对湿度亦呈正相关,与当年4-9月平均相对湿度呈极显著正相关,与前一年4-9月平均相对湿度呈显著正相关;与当年月平均相对湿度在1月、2月为负相关,与其他月份均呈正相关,与前一年的月平均相对湿度只有2月呈负相关,其他月份均为正相关。The correlation between temperature,precipitation,relative humidity and ring width of Camellia rubimuricata was analyzed by the dendroclimatic method.The results showed that 1） Camellia rubimuricata presented high sensitivity to climatic changes,2） the ring width of Camellia rubimuricata was negatively correlated to average annual temperature of current and preceding year,significantly negatively correlated to average temperature from April to September of the current year,negatively correlated to average temperature from March to November of the current year,positively correlated to monthly average temperature of December,January and February,positively correlated to monthly average temperature of February,August,September and December of the preceding year,3） the ring width of Camellia rubimuricata was very significantly positively correlated to annual precipitation of the current year,significantly positively correlated to annual precipitation of the preceding year,very significantly positively correlated to precipitation from April to September of the current year,positively correlated to precipitation from April to September of the preceding year,negatively correlated to precipitation of May and November of the current year,and negatively correlated to precipitation of January,February,April,November and December of the preceding year,4） the ring width of Camellia rubimuricata was very significantly positively correlated to average annual relative humidity of the current year,positively correlated to average annual relative humidity of the preceding year,very significantly positively correlated to average annual relative humidity from April to September of the current year,significantly positively correlated to average annual relative humidity from April to September of the preceding year,negatively correlated to monthly average relative humidity of January and February of the current year,and negatively correlated to monthly average relative humidity of February of the preceding year.
