摘要/Abstract

摘要： 利用来自全国66个日射站的太阳辐射及679个常规气象站的日照资料,在数据集群的基础上,建立了直接透射率的不同(各站各月模式、各月模式、各站模式、综合模式)估算模式,研究直接透射率的推算方法。经过对各种模式计算结果的误差指标的综合评估分析,最终确认各月模式为最优模式。文章选取各月模式,在GIS支持下利用Kriging内插法,得到1km×1km的全国月直接透射率空间分布图,并分析了月直接透射率的空间分布及主要影响因素。

关键词: 太阳辐射直接透射率, 估算模式, Kriging内插法

Abstract: Based on the data of the solar radiation in 66 radiation stations and the data of the sunshine in 679 normal meteorological stations in China,the different estimation models for calculation of the direct solar radiation transmission rate,such as each month model for each station,each month model for all stations,each station model for all months,and a model for all months and stations,were established.The estimation method of the direct solar radiation transmission rate was studied.Based on the assessment of the errors of the calculation result of all the models,the each month model for all stations was chosen as the best model for calculation of the direct solar radiation transmission rate.The spatial distributing maps for the monthly direct solar radiation transmission rate for China at grid 1km×1km were made by using the GIS and Kring interpolation method.The spatial distributing of the direct solar radiation transmission rate and its main influencing factors were analyzed.

Key words: Direct solar radiation transmission rate, Direct solar radiation transmission rate, Estimate model, Kriging interpolation method
