| 摘 要： | 利用1961~2002年中国大陆地区60个站月平均总辐射资料,讨论了我国大陆地区总辐射在年际—年代际时间尺度上的演变特征。研究表明:我国大部分地区总辐射的变化特征有很好的一致性。大部分地区总辐射自20世纪60年代开始呈现减少的趋势,这一趋势一直持续到1990年前后,其后大部分地区总辐射有明显增加的趋势。同时分析了各区总辐射的线性倾向系数以及其演变趋势的地理分布。 |

| Abstract: | Regional characteristics of global solar radiation evolution in China were analyzed based on the monthly mean global solar radiation data of 60 stations from 1961 to 2002.The results showed that evolution of global solar radiation at different places coincided with each other very well.The global solar radiation had obvious decreasing trends from 1961 to 1990 in most parts of China.An abrupt change occurred at the beginning of 1990s,followed by sustained increase. The magnitude of the linear trend on a regional basis and for the country as a whole was computed.Geographical distribution of inter-annual trend of global solar radiation during this period was also presented in this paper. |
| Keywords: | China region global solar radiation K-Cluster analysis M-K method |
