利用 SMARTS 模式计算晴天总辐射,充分考虑大气对太阳辐射的削弱作用和海拔高度的影响,以四川省为例,建立了复杂自然环境条件下基于日照百分率的太阳能资源气候学计算方程。该方法不仅物理意义明确,而且计算结果误差明显降低;与实测值相比,7个辐射站年地面太阳总辐射曝辐量的相对误差均低于7%;与初始值采用天文辐射曝辐量的方法相比,无论是相对误差值还是离散程度,均降低一半以上。该方法较好地解决了在一个地形复杂、气候多变的区域采用同一计算方程的难题,从而有效避免了过去采用分区方法带来的边界不连续问题,对我国东西高差大、干湿变化明显的特殊情况具有应用价值。
利用 SMARTS 模式計算晴天總輻射,充分攷慮大氣對太暘輻射的削弱作用和海拔高度的影響,以四川省為例,建立瞭複雜自然環境條件下基于日照百分率的太暘能資源氣候學計算方程。該方法不僅物理意義明確,而且計算結果誤差明顯降低;與實測值相比,7箇輻射站年地麵太暘總輻射曝輻量的相對誤差均低于7%;與初始值採用天文輻射曝輻量的方法相比,無論是相對誤差值還是離散程度,均降低一半以上。該方法較好地解決瞭在一箇地形複雜、氣候多變的區域採用同一計算方程的難題,從而有效避免瞭過去採用分區方法帶來的邊界不連續問題,對我國東西高差大、榦濕變化明顯的特殊情況具有應用價值。

Using SMARTS to calculate clear-sky global radiation,fully thinking of the weaken effects of the alti-tude and the atmosphere,in terms of water vapor in atmosphere,meteorological visibility and O3 content, a climatology universal calculation equation on solar energy resource is established,which is based on the percentage of sunshine.This method is different from the calculation of solar energy resources using extra-terrestrial radiation.Taken Sichuan Province as an example,results show that this method not only has unambiguous physical meaning,but also decreases the error of the calculating result obviously.7-station annual value relative error is less than 7%,with the highest of 6.26% for Panzhihua and the lowest of-0.67% for Luzhou,the error is significantly lower than that in previous studies of Sichuan.Contrast with results from extraterrestrial radiation,not only the quantity but also discreteness of relative error de-creases by more than a half.For the distribution of solar energy resources in Sichuan,it is large in the east part and low in the west part.From the change of each month,solar energy resources in the western plat-eau is relatively stable,the minimum monthly solar radiation for a maximum of 62% at Litang Station;so-lar energy resource in the east basin is fluctuant,the minimum monthly radiant exposure is only accounted for 22% of the maximum value at Zigong Station.The climatology universal calculation equation on solar energy resource can better resolve the problem of using the same calculation equation in the region which has complex topography and climate,avoiding the boundary discontinuity,effectively which is brought by using partition method in the past,and it is useful for special regional situations of huge relative altitude between the east part and the west part of China with obvious changes of dry and wet.This statistical e-quation is suitable for the calculation of solar energy resources,first of all,each input parameter on aver-age is needed.If the equation is used to calculate the total radiation exposure radiation in a special month or a special year,it will result in great error.
