| 摘 要： | 该文统计了中国地区1961～1990年近30年地面总辐射、直接辐射和散射辐射的变化。结果表明，中国大部地区近年来太阳总辐射和直接辐射呈减少趋势。在排除了大部分云的影响后，对太阳辐射的统计也给出了类似结果。对云量和地面能见度近30年变化规律的统计分析发现，中国大部分地区的能见度呈下降趋势，但云量的变化并不明显。初步认为，近年来大气混浊度和大气中悬浮粒子浓度的增加是引起中国某些地区直接辐射量下降的可能原因之一。

| Abstract: | The variation trends of global radiation, direct solar radiation and scattering solar radiation data in China from 1960 to 1990 are analyzed. The results show that the global radiation and direct radiation in most part of China had very obvious decreasing trends in recent years. The same conclusion is got after partly removing the effect cloud. The variable patterns of the cloud amount and surface visual range in recent 30 years were calculated, and the results show that the visual ranges in most part of China decreased, but the variations of cloud amount were not obvious. Based on the above analysis, the preliminary conclusion is drawn that the increase of the atmospheric turbidity is one of the possible reasons for the obvious decrease of the surface solar radiation. |
