摘　　要：为建立我国建筑节能用基础气象数据库,针对我国气象数据实际记录状况,需分析不同统计时长对典型气象年挑选结果的影响。分别在5个建筑热工设计分区的11个二级区划中各选取一个典型城市,采用美国Sandia国家实验室法,对比缩短后的统计时长(3~15 a)和长期30 a挑选出的不同典型年结果的差异。结果表明:为了控制辐射标准差的平均波动幅度在1 MJ/m2以内,同时温度标准差的平均波动幅度也在1℃以内,最少要用8 a统计时长的数据,但根据城市位置和气候的不同,仍然会有部分城市的温度或辐射标准差的波动幅度较大。In order to establish a basic meteorological database for energy saving of buildings in China,it is necessary to analyze the effect of different record periods on selection results of typical meteorological years.In this paper,11 typical cities were selected which represended mateorolgical states of the 11 sub divisions of the five building thermal design divisions.The Sandia National Laboratory method was used to compare the differences of shortened record periods(3 to 15 years)with the long-term records of 30 years in typical meteorological years.The results showed that/m2 and the average fluctuation range of standard deviation of temperature within 1℃,it was necessary to use data at least for 8 years.However,depending on the location of the city and climate,there would still be large fluctuations in standard deviations of temperatures or solar radiation in some cities.
