摘　　要：该文利用中国多年气候资料,参照建筑设计标准,采用气象学中的五日滑动平均法,计算了不同地区在不同温度界限下日平均温度小于等于该界限温度的持续时间,并同中国连栋温室实际采暖期相比较,确定了中国大型连栋温室采暖期的计算方法;利用日本度时法计算了中国各地大型连栋温室的期间热负荷,进而计算采暖能耗。结果表明:以当地累年逐日平均气温≤10℃的持续日数作为连栋温室的采暖期和实际情况相符。分析结果表明,从南方部分地区采暖期为0 d到青海、西藏大部分地区365 d,说明中国连栋温室对热量的要求南北差异极大。通过计算中国各地的采暖能耗,表明各地最大采暖耗煤量出现在1月,其次为12月和2月,北方1月平均耗煤量占年耗煤量的30%左右,12月占20%以上,2月占20%以下,年耗煤量在中国范围内也存在极大差别。大型温室采暖期的确定及采暖能耗的计算可为中国连栋温室采暖设计标准化提供依据,为温室节能提供参考。Using architectural design standard as a reference, the climatology method of five-day sliding average was adopted to calculate the durations of daily average temperature less than many given temperatures, to compare these calculated durations with the actual heating periods of multi-span greenhouse in China, the heating duration of multi-span greenhouse was determined. The heating load in China was also obtained by adopting Japan＇s degree-hour method. The results are as follows： 1） The determined heating period, which was obtained by duration of daily average temperature less than 10℃ of local 30 years＇ daily temperature, is in good agreement with that of matter-of-fact, and it varies from zero at the southern part areas to 365 days at most areas in Qinghai province and Tibet Automomous Region; 2） The maximum coal consumption occurs in January, next does in December and February, by calculation the average coal consumption in January is 30% of whole year in north China, more than 20% in December and less than 20% in February. There arc significant differences within different areas on the annual energy consumption, The calculation of heating duration and energy consumption can provide basis for on standardized heating-design as well as reference for the energy-saving for the multi-span greenhouse.
