Abstract:

 In accordance with the solar energy resource assessment standards issued by China Meteorological Administration，the total　solar radiation in Shanxi was calculated by means of climatology analysis methods using the recent 30 years data of total solar radiation　from 3 radiation stations and sunshine hours data from 105 meteorological stations． Potential use value of solar energy was evaluated　based on the analysis of spatial distribution and temporal evolution of total solar radiation and various solar energy parameters obtained　from sunshine observation．Results show that values of total solar radiation were in the range of 4 600－5 800 MJ /( m²•a)in Shanxi，which characterized by higher values in the north areas and lower values in the south areas，meanwhile a decrease trend was found in　recent 30 years．The annual variation of total solar radiation was apparent unimodal distribution with the maximum in May and minimum　in　December．In general，solar energy resources in Shanxi are rich and stable，especially in northern areas，where are suitable for the　development and utilization of solar energy．The results from this study can provide a scientific basis for the development and utilization　of solar energy resources in Shanxi．

Key words:  total solar radiation, regional characteristics, solar energy assessment

摘要：

按照中国气象局发布的太阳能资源评估方法， 利用山西省近30 a3个辐射观测站的太阳总辐射资料和105个站的日照资料，采用气候学方法计算了山西省的太阳总辐射，在分析山西省太阳总辐射的空间分布和时间演变特征的基础上，计算了山西省太阳能资源的各种参数，对区域太阳能资源潜力进行了客观评估结果表明山西省太阳能资源储备丰富稳定可开发利用日数较多，特别是山西北部地区，尤其适合进行太阳能资源开发利用。
