Change of Solar Resources Characteristics and Assessment in Kangping of Liaoning

利用1961～2009年康平县太阳总辐射和日数时数资料对康平太阳能资源特征进行分析与评估。结果表明，康平太阳能资源年总量及月值均呈下降减少趋势；在49a里总辐射年总量减少534．20MJ／m^2，年日照时数减少228h，在近10a太阳能资源略有回升；康平太阳能资源较丰富，历年变化稳定，具有开发利用的潜力。

Based on data of total solar radiation and sunshine hours during 1961 - 2009, the characteristics of solar energy in Kangping was analyzed and evaluated. The results showed that the annual and monthly amount of solar resource in Kangping indicate decreasing trend; the total radiation in 49 a decreased 534.20 MJ/m^2, annual sunshine hours decreased 228 h, solar resources in recent 10 years picked up slightly. The solar resource in Kangping is abundant and stable over the years, which has the development and utilization potential.
