| 摘 要： | 通过对玛沁县1995～2004年气温与降雨量的统计分析，探讨了玛沁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年玛沁县平均气温逐渐升高，2003年达到最高值，与1995年相比平均气温升高了1．21℃；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；在月间或短期尺度上，气温对降雨量的时空分布影响不大，但在全年尺度上气温对降雨量的时空分布有明显的影响。

| Abstract: | 10 years of the temperature and rainfall in Maqin County from 1995 to 2004 was statistically analyzed,and the variation trend of temperature and rainfall and the relevance of them were discussed.The results showed that from 1995 to 2004,the average temperature gradually increased,peaked in 2003,compared with the average temperature in 1995 increased by 1.21 ℃;and rainfall changes over the years was not obvious,in the year scale changes in rainfall and temperature changes are basically the same,showing a clear seasonal variation. |
