| 摘 要： | 利用1960—2009年的年月平均气温观测资料,分析了被检站和参考站的年、季变化趋势特点,着重研究了大型火电厂的热排放对当地气温的影响程度和相对贡献比例。从增温趋势看,被检站和参考站年平均气温增温速率分别为0.33～0.48℃？10a和0.21～0.33℃？10a,年热排放增温率为0.11～0.20℃？10a。热排放引起的四季增温速率为春秋强,冬季次之,夏季最小。火电厂的热排放对当地气温增温的贡献显著,表现为夏季最大,春秋季次之,冬季最小,对年平均气温序列的增温贡献率为31%～49%。 |

| Abstract: | Based on annual and monthly average temperature observational data from 1960 to 2009, annual and seasonal trend character is analyzed. The influence degree and the relative contributing ratio of big thermal power plant’s heat discharge on local air temperature is primary study. Temperature rise considered, the warming rate of annual average temperature of detected and referenced stations is 0.33-0.48 ℃ ？10a and 0.22-0.33 ℃ ？10a, respectively. The warming rate of annual heat discharge is 0.11-0.20 ℃？10a. Among seasonal warming rate, the most one is in spring and autumn, and winter takes second place, summer is the least. Warming contributions of heat discharge to local temperature is remarkable with the sequence of summer, spring, autumn and winter from big to small. And its warming contribution to annual average temperature is 31%-49%. |
| Keywords: | thermal power plant heat discharge temperature serial warming contribution |
