1961-2010年黑龙江省太阳能资源特征分析与评估

利用1961-2010年黑龙江省5个辐射站和32个地面基准站资料，分析黑龙江省太阳能资源的时空分布特征，并从太阳能资源丰富度及资源稳定性等方面进行资源评估。结果表明：黑龙江省年均太阳总辐射显著减少，1月和12月减少最明显，20世纪70年代太阳辐射最强，80年代最弱；总辐射和日照时数的空间分布呈西丰(多)东贫(少)的趋势。全省太阳能资源的稳定性较高，其中松嫩平原西部的太阳能资源最丰富、稳定性最高，适合集中建设大型太阳能电站。

Analysis and assessment of solar energy resource in Heilongjiang province from 1961 to 2010

Based on the observational data from 5 global solar radiation stations and 32 weather stations in Hei- longjiang province from 1961 to 2010, the characteristics of the spatial-temporal distributions of solar energy re- source were analyzed. The abundance and stability of solar energy resource were assessed. The results indicate that the average annual global solar radiation decreases, especially in January and December： The global solar radiation is the strongest in 1970s and weakest in 1980s. The distributions of the global solar radiation and sunshine duration are consistent, and both are more abundant in the west than in the east. The stability of solar energy resource is good in Heilongjiang province, especially in the west of the Songnen plain. It is suitable to build the solar energy power station because of the abundant and stable solar energy resource in the west of the Songnen plain.
