摘　　要：通过对甘德县1995～2004年10年来气温与降雨量的统计分析,探讨了甘德县气温和降雨量的变化趋势及二者的相关性。结果表明,1995～2004年平均气温逐渐升高,2003年达最高值,与1995年相比平均气温升高了1.30℃;历年降雨量变化规律不明显,在全年尺度上降雨量的变化与气温变化基本一致,表现出明显的季节性变化规律。Through the statistical analysis of the temperature and rainfall in Gande County from 1995 to 2004,the change trend of temperature and rainfall in Gande County and their correlation were discussed.The results showed that the average temperature gradually increased from 1995 to 2004 and reached the maximum in 2003.The average temperature increased 1.30 ℃ than that in 1995.The change laws of the rainfall over the years were not obvious.The changes of rainfall in the year scale were basically accordant with the temperature changes,showing an obvious seasonal variation.
