安徽省太阳辐射能资源的时空分布特征与可利用潜力评估

为了明确安徽省太阳能资源的时空分布特征与可利用潜力，基于安徽省20个气象站台1970—2020逐日日照时数数据，以亳州、合肥和黄山作为安徽的代表站点，分析安徽省太阳辐射能的时空变化及可利用潜力。结果表明：安徽省太阳辐射空间分布呈北多南少，太阳辐射量近51年来呈下降趋势。皖北地区太阳辐射量最大、波动也较大，皖中以及皖南太阳辐射量在一定范围内波动。各代表站点太阳辐射量具有11年左右周期变化，与太阳活动周期具有一致性。安徽省总体处于太阳能资源丰富区，利用期较长，日照稳定。安徽省屋顶可装光伏电池面积为1 277.51 km²，集中于安徽省中部及北部，占全省面积的0.9%，发电潜力约为2.05×10¹⁴kJ。

Spatial and temporal distribution characteristics and evaluation of solar energy resources in Anhui Province

In order to clarify the spatial and temporal distribution characteristics and utilization of solar energy resources in Anhui Province, this study analyzed the spatial and temporal variation and utilization potential of solar radiation energy in Anhui Province based on the daily sunshine hours data of 20 meteorological stations from 1970 to 2020, with Bozhou, Hefei and Huangshan as representative stations in Anhui Province. The results showed that the spatial distribution of solar radiation in Anhui Province was more in the north and less in the south. The solar radiation in northern Anhui fluctuated greatly, while the solar radiation in central Anhui and southern Anhui fluctuated within a certain range. The 11-cycle variation of each representative station was consistent with the solar activity cycle. Anhui Province is generally in the area of abundant solar energy resources, with a long utilization period and stable sunshine. The area of photovoltaic cells that could be installed on the roofs of Anhui Province was 1 277.51 km, concentrated in the central and northern parts of Anhui Province, accounting for 0.9% of the province''s area, with a power generation potential of about 2.05×10¹⁴kJ.
