摘要
利用1961-2017年内蒙古8个太阳辐射站和119个气象站数据资料,基于气象行业标准《太阳能资源评估方法》估算内蒙古太阳总辐射量,分析月、季和年的时空分布特征并进行太阳能资源评估。结果表明:(1)全区平均太阳总辐射量年变化总体表现为缓慢减小的趋势,2017年达到最低,为5807MJ/m^2;空间分布呈现从东北到西南递增的趋势,介于4858~6925MJ/m^2之间。(2)季节变化表现为夏季最高,春、秋次之,冬季最低,夏季7月在阿拉善盟西北部的额济纳旗和拐子湖一带太阳总辐射量最高,太阳能资源的开发利用优势最大。(3)内蒙古除呼伦贝尔市外其他盟市太阳能资源稳定度均为'稳定',中西部地区太阳能资源'最丰富',建议优先选择内蒙古中西部的丘陵阳坡、荒漠化草原、及沙地等建设大规模光伏发电站。
Based on the meteorological industry standard'Solar Energy Resource Assessment Method',we estimated the total solar radiation in Inner Mongolia and analyzed the spatial and temporal distribution characteristics of the solar energy resource with the data of 8 solar radiation stations and 119 meteorological stations in Inner Mongolia from 1961 to 2017.The conclusions are as follows:(1)The annual change of solar radiation in the whole region showed a trend of slow decrease,reaching the lowest in 2017,about 5807 MJ/m^2.The spatial distribution of total solar radiation was increasing from northeast to southwest,the annual total solar radiation in the region ranged from 4858~6925 MJ/m^2.(2)The seasonal change showed as the highest in summer,followed by spring and autumn,and the lowest in winter.The areas of Ejin banner and Guaizi lake in the northwest of Alxa league had the highest solar radiation in July,which is suitable for the development and utilization of solar energy resources.(3)In Inner Mongolia,the solar energy resources in the central and western regions are'the most abundant',and the stability of solar energy resources is'stable',except Hulun Buir.Therefore,it is suggested that large-scale photovoltaic power stations should be constructed in the central and western regions of Inner Mongolia,especially in sunny slopes of hilly,desertification grasslands and sandy land.
