摘要 | 对渭河流域及其周边45个气象站点近60年的气温特征值,做空间插值、线性回归分析、气温突变分析和趋势分析。结果表明:1)1951~2009年间渭河流域年平均气温、年平均最低气温均呈显著上升趋势,年平均气温和年平均最低气温的的增温速率分别为0.252℃/10a和0.261℃/10a,年平均气温大于9℃区域所占流域总面积比,60年间上升34.78%;年平均最低气温大于3℃区域所占流域总面积比,60年间上升17.2%;2)年平均最高气温除1980s下降外,其余年代呈现上升趋势,增温速率为0.255℃/10a,其大于16℃区域所占流域总面积比,首先从1950s的46.27%下降至1980s的37.15%,而后又上升至2000年后的81.63%;3)年均温、年平均最低温和年平均最高温变化的转折点在1990年前后;4)气温日较差从1950s至1970s呈下降趋势,进入1980s后略有上升,其中气温日较差大于11℃区域所占流域总面积比,首先从1950s的55.96%下降至1980s的41.58%,而后又上升至2000年后的61.07%。 |
其他摘要 | Based on the atmospheric temperature data of 45 stations in and around Wei River basin during 1951 ~ 2009,spatial interpolation,linear regressive analysis and climatic mutation analysis were applied to analyze the climate trend and so on. Results showed that: ( 1) The annual mean temperature and the minimum temperature of the basin showed a increasing trend,rising at the rates of 0. 252℃ /10a and 0. 261℃ /10a respectively. The proportion of the area where the average annual temperature was more than 9 increased by 34. 78% and where the average annual temperature was more than 9 increased by 34. 78% from 1951 to 2009. ( 2) Apart from the 1980s,the average annual maximum temperatures have been in an ascending trend,rising at the rates of 0. 255℃ /10a. The proportion of the area where the average annual maximum temperatures were more than 16℃ decreased from 46. 27% in 1950s to 37. 15% in 1980s,then increased to 81. 63% after 2000. ( 3) The turning points among the average annual temperature,the average minimum temperature and the average annual maximum temperature located around 1990. ( 4) Average diurnal range in temperature had a decreasing trend from 1950s to 1970s and the warming trends started in the 1980s. The proportion of the area where average diurnal range in temperature was more than 11℃ decreased from 55. 96% in 1950s to 41. 58% in 1980s,then increased to 61. 07% after 2000. |
