| 摘 要： | 采用汉中市1951～2009年气温和降水资料,对近59年汉中市气候变化特征进行了分析。结果表明:汉中市年平均气温以0.018℃/a的速度递增,1997年以后递增幅度更大。年降水量以2.96mm/a的速度递减,1990年以后递减趋势较明显。利用M-K法检验,近59年汉中市气温存在突变现象,突变点在1996年,而年降水量没有明显突变现象。针对气候变化,结合汉中市实际情况提出了一些参考性建议。

| Abstract: | Using Hanzhong city’s temperature and precipitation data in 1951～2009,the characteristics of climatic change of recent 59 years in HanZhong city were analyzed.The results showed that in Hanzhong city,the annual average temperature increased by 0.018℃/a,the increasing amplitude was more bigger after 1997.Annual precipitation was decreasing progressively by 2.96mm/a,the decreasing tendency was obvious after 1990.The M-K law check showed that in recent 59 years,the temperature existed abrupt change phenomenon,the point of discontinuity was in 1996,but the annual precipitation did not have the obvious abrupt change phenomenon.In view of the climatic change,combined with the Hanzhong actual situation,some referential proposals were put forward. |
