| 摘要: |
| 根据鄯善县1971—2010年气温、降水量、风速等资料，利用线性趋势法和距平及累积距平等方法对鄯善县绿洲气候变化进行分析。结果表明：(1) 近40 a鄯善县年平均气温呈波动上升趋势，线性拟合气候倾向率为0.49℃·10a-1，各季变暖趋势相同，春夏秋冬四季平均气温线性拟合气候倾向率分别为0.35、0.33、0.4℃·10a-1及0.43℃·10a-1。年平均最高气温缓慢上升，年平均最低气温增温明显。(2) 近40 a降水量总体为波动减少趋势，线性拟合气候倾向率为-0.55 mm·10a-1，夏季和秋季降水量减少明显。(3) 近40 a平均风速总体呈缓慢减小趋势，线性拟合气候倾向率为-0.05 m·s-1·10a-1。综合气温与降水变化状况，鄯善县绿洲气候呈暖干化发展趋势，气温与降水存在突变情况，年代分布有明显的阶段性、季节差异性特征。 |

| Abstract: |
| Based on the information of temperature, precipitation and wind speed etc from 1971 to 2010 of Shanshan County, using the methods of linear trend and accumulated anomaly, have carried out the analysis of climatic change in oasis of Shanshan County. The results indicated that: (1) The annua
l mean temperature has assumed a undulated increase trend in near 40 years, the climatic tendency rate by the linear fitting was 0.49℃/decade, the trend changing warm in each season was same, the mean temperature of the climatic tendency rate by the linear fitting in spring, summer, autumn and winter was 0.35℃/decade, 0.33℃/decade, 0.4℃/decade and 0.43℃/decad respectively. The annual mean maximum temperature was slowly risen, the annual mean minimal temperature was obvious warm. (2) The annual gross precipitation was a undulated decrease trend during 40 years, the climatic tendency rate by the linear fitting was -0.55 mm/decade, the precipitation reduce was obvious in summer and autumn. (3) The annual mean wind velocity was assumed a slowly decrease trend during 40 years, and the cli
matic tendency rates by the linear fitting was -0.05 m/s/decade. Synthesized the change situation of the temperature and precipitation, The oasis climate has assumed a warm and dry developing trend in Shanshan County, the temperature and precipitation existed a mutation, also the years distribution had the obvious period change and seasonal differences. |
