摘　　要：为客观分析沈阳冬季不同性质地表温度特征,给沈阳城市建设提供更具针对性的气象预报服务,在试验地对不同性质的地表(水泥表面、草坪表面及积雪表面)进行了温度观测,并分析其温度变化特征,用统计计算方法给出了不同性质地表温度与观象台百叶箱气温之间的相关系数、不同性质地表面温度依赖于观象台百叶箱气温及天空总云量的回归方程;提出模式识别方法、概率统计方法以及预报经验评估方法相互结合的不同性质地表面温度预报综合集成技术。In order to analyze the temperature characteristics at different surfaces during winter and provide high quality weather forecast serv- ice for Shengyang City＇s construction, the temperatures of different surfaces （cement surface,lawn surface and snow surface） were determined and its change characters were analyzed. The corre]ation coefficients between temperatures at different surfaces and the louvered screen tem- peratures,the regression equation were obtained by statistics. Then,a meta-synthetic forecasting technique of the temperature at different sur- faces which is related to the pattern recognition method, probability-statistical method and experience estimation method was put forward.
