摘　　要：基于贵州全省气象站1961-2009年的逐日气温资料,计算了0～30℃每1℃范围内的活动积温(温度界限内积温),并针对其变化特征开展了分析研究。结果显示,温度界限内积温不仅能够反映活动积温在各个温度范围的分配状况,同时还包含温度持续时间的信息,是温度对时间积分的具体体现;贵州温度界限内积温随温度界限呈单峰曲线变化,峰值对应的温度界限全省平均为22℃,各站分别为17(威宁)～27℃(赤水、松桃、从江等),界限温度随海拔升高其递减率为0.51℃.100m-1;温度界限内积温峰值对应温度界限反映地区热量资源总量的同时,能够体现出热量分布的主要温度范围,可以为更加全面地了解热量资源特征提供参考。Integrated temperature in each 1℃ range of Guizhou were calculated and analyzed in this study.The results showed that integrated temperature of each 1℃ range was the manifestation of integrated temperature definition,which reflected the distribution of active integrated temperature in each temperature range,and also showed the time of duration in the range.Integrated temperature in each range changed with a single peak curve,the average peak value of the province emerged in 22℃,and each weather station was between 17℃（Weining） and 27℃（Chishui,Songtao,Congjiang,etc.）,which linearly droped in elevation by 0.51℃·100m-1.The temperature range of the peak value reflected the total heat resources,and it also showed the mainly distribution in temperature ranges of heat resources,by which could know heat resources more in-depth.
