摘　　要：通过确定我国连栋温室室外设计温度,计算分析了室外设计温度在全国的分布状况,进而计算连栋温室最大热负荷:①采用当地30年最低日平均温度和当地30年累年最冷月温度做为基本值,确定了连栋温室采暖室外设计温度;②我国内蒙的东北部、黑龙江大部分地区、新疆的北疆地区及青海的部分地区冬季采暖室外设计温度都在-30℃以下,连栋温室的采暖容量和设备建造投资过大;③在全国范围内,最大热负荷的分布存在极大差异,北方大,南方小。全国的高值中心分别出现在黑龙江北部、内蒙古东北部、新疆的北疆及青海的部分地区,最大热负荷都在300W/m2以上。连栋温室室外设计温度的确定和最大热负荷的分布计算可为我国连栋温室合理布局、标准化设计及温室节能提供参考。The disribution of designed outside temperature and the maximum heating load of multi-span greenhouse in China are calculated and analyzed after having determined the designed outside temperature： （1）ing the lowest daily temperature and the coldest monthly temperature of local 30 years,the designed outside temperature has been determined; （2）the designed outside temperature are below -30℃ in the northeast of Dongbei,north of Xinjiang and part areas of Oinghai,thus,the heating investment on building multi-span greenhouse must be high in those places; （3）the distribution of maximum heating load is different from north to south,the highest values are in the north of Helongjiang,northeast of inner Mongolia,north of Xinjiang and part areas of Qinghai,these are above 300W/m^2. The calculation of designed outside temperature and maximum heating load can be suggestion on rational distribution of multi-span greenhouse and its heating design standardization as well as reference for the energy-saving.
