摘　　要：以中国93个城市相同年份的太阳辐射和空气温度为统计依据,采用计算模型和统计方法获得南向垂直面总辐射和采暖度日数,分析近50 a内中国的南向垂直面总辐射资源和空气温度变化规律,计算并呈现全国范围的辐射温差比。结果表明,近50 a内中国的南向垂直面总辐射资源显著下降,而年均温度和冬季温度则出现上升,相比于1971~1980年,1983~2012年被动式太阳能采暖设计气候资源潜能降幅明显。Based on 93 cities solar radiation and air temperature during the same period in China,global solar radiation on south-faced wall and heating degree days are calculated according to the models and statistics,irradiation degree-day is presented spatially,it is concluded that global solar radiation on south-faced wall is decreasing significantly rather the yearly and winter temperature are both increasing significantly. The climate potential for passive solar heating in China is decreased significantly between 1983-2012 comparing between 1971-1980.
