摘要: 采用随州周边4个辐射观测站 (武汉、郑州、西安1961-2017年,南阳1990-2017年)日照百分率和实测日太阳总辐射值,结合一元线性回归法拟合出适用于计算随州太阳总辐射的公式参数,再将随州本站及周边17个市县气象站2011-2016年日照百分率代入公式,推算出随州市境内月太阳总辐射值,再利用气候学计算方法和空间插值法对全年和各个季节太阳总辐射空间分布和时间变化展开剖析。其结果显示:随州市太阳总辐射的区域分布受其撮箕样地形影响,全年和各季节均表现出南多北少的特性,太阳总辐射在冬季为低值季,夏季为高值季,春秋适宜;年际和各季节的太阳总辐射值均呈减小趋势,且夏季减小速率最大;春夏秋三季的太阳总辐射偏大偏小期与全年变化步调相似,但冬季变化不显著。

Abstract: To explore and utilize solar radiation in Suizhou more efficiently, and better serve local Sannong issues (namely agriculture, rural community and farmers) and ecological civilization construction, based on the percentage of sunshine and daily total solar radiation from 4 radiation stations and 16-city(county) weather stations around Suizhou, we found a suitable formula parameter for calculating total solar radiation and the monthly total solar radiation in Suizhou, and analyzed annual and seasonal spatial and temporal distribution of solar radiation with the methods of climatological calculation and space interpolation. The results showed that: the spatial distribution of solar radiation in Suizhou was less in the north and more in the south of the whole year and each season; for temporal distribution, the total solar radiation was the highest in summer, and the lowest in winter; in addition, there was a decreasing trend in total solar radiation, especially during summer. The spatial and temporal distribution of total solar radiation in Suizhou is consistent with that in China and Hubei Province. However, due to its unique geographical environment, the total solar radiation is more in south and less in north in Suizhou.
