摘要: 利用乌兰浩特站1951-2006年温度、无霜期、≥10℃活动积温等资料,分析了乌兰浩特市近56a来热量资源的变化趋势。结果表明,近56a来,乌兰浩特市热量资源呈增加趋势,尤其是20世纪90年代以来,无论是平均气温、无霜期还是≥10℃活动积温增加趋势更加明显,增加速度加快。分析认为,热量资源的增加使农作物生长期明显延长,有利于种植高产中晚熟的玉米等农作物品种,有利于增加作物产量和农民收入。但热量资源的增加同时加剧了城市夏季的高温酷热程度,加大能源消耗。

Abstract: By using the data of temperature,frost-free period and the cumulative temperature of the period that temperature higher than 10℃ of Wulanhaote city during 1951-2006,the variation of heat resource in recent 56 years was analyzed.The results showed that heat resource increased,especially since 1990s.The average annual temperature and average seasonal temperature increased obviously.The growth period of crops was prolonged obviously by the increase of heat resource,which was beneficial to grow high-yielding plant in the late-maturing varieties of maize and other crops.However,the increase of heat resource exacerbated the city's high-temperature hot summer extent and increased energy consumption.

Key words: Temperature, Frost-free period, Active accumulated temperature, Agricultural production, Ecological environment
