摘要
对1951～2007年营口市稳定通过0℃、10℃积温和积温日数及其变率的分析表明：（1）近57年来营口市稳定通过0℃和10℃积温及积温日数呈递增趋势，其中稳定通过10℃积温、积温日数比通过0℃的递增趋势要强。（2）各阶段稳定通过O℃和10℃积温变化趋势不同，第1个和第2个30年呈现递增趋势较弱、第3个30年和最近30年呈强递增趋势。（3）近57年营口市稳定通过0℃和10℃积温日数递增变化中，后期递增趋势较前期更为显著：最近30年营口市稳定通过0℃和10℃积温递增趋势显著加强趋势与全球变暖的大背景进一步加强趋势相一致。
The accumulated temperature and accumulated temperature days though 0 and 10℃ stably and the variation rate in Yingkou City from 1951 to 2007 were discussed. The accumulated temperature and accumulated temperature days though 0 and 10℃ stably during recent 57 years showed the increasing trend and the increasing trend of the accumulated temperature and accumulated temperature days though 0℃ stably was stronger than that though 10℃ stably. The change trend of the accumulated temperature thongh 0 and 10℃ stably was different in different stages. The increasing trend was weaker in the first and second 30 years and that was strong in the third and latest 30 years. The decreasing tend of accumulated temperature days through 10 stably in Yingkou City during 57 recent years was more significant than that through 0℃. During the latest 30 years, the increasing trend of accumulated temperature through 0 and 10℃ stably was accordant with the global warming.
