摘　　要：将宝天曼保护区人工气象站1996～2000年、2006～2010年这10年气温与降雨量数据进行统计分析,探讨宝天曼保护区气温和降雨量的变化趋势及二者的相关性。结果表明,1996～2010年宝天曼自然保护区平均气温逐渐升高,2006～2010年平均气温比1996～2000年高出0.40℃,其差异未达到显著水平(t=0.23,P=0.6417),但夏季温度有降低的趋势;宝天曼年降雨量有逐年减少的趋势,2006～2010年平均降雨量比1996～2000年减少了9.56 mm,其差异没有达到显著水平(t=0.51,P=0.4961),但夏季降雨量有增加的趋势;降雨量的变化与气温变化一致,表现出明显的季节性变化规律。最冷月、最热月、生长季的温度与降雨量相关分析都达到了极显著水平,全年数据达到了显著水平。Through the statistical analysis of the temperature and rainfall in Baotianman nature reserve from 1996 to 2000 and 2006 to 2010,the change trend of temperature and rainfall and their correlation were discussed.The results showed that the average temperature gradually increased from l996 to 2010,the average temperature of 2006～2010 was 0.40 ℃ higher than that of 1996～2000;but the difference wasn＇t significant（t=0.23,P=0.6417）.The average precipitation of 2006～2010 was 9.56 mm lower than that of 1996～2000（83.99 mm）,but the difference wasn＇t significant（t=0.51,P=0.4961）.The temperature of the coldest month,the hottest month and the average temperature of growing season were very significantly correlated to precipitation;the temperature of the whole year was significuntly correlated to precipitation.
