摘要: 利用新疆1961-2005年88个气象观测站点系统的气象观测资料,分析了新疆日平均气温稳定通过0℃的初日、终日、初终间日数、积温的空间变化、年际变化、年代际变化。结果发现,全疆及各区域日平均气温稳定通过0℃的积温变化均呈增加的趋势,全疆范围内每10a增加43.1℃.d。其中,增加最多的是塔城盆地,平均每10a增加89.6℃.d;各区域的初终间日数变化都呈增加趋势;初日变化趋势不一致,北疆(除伊犁河河谷)、天山山区和哈密盆地推迟。南疆、伊犁河河谷、淖毛湖盆提前;终日呈推迟的趋势。通过分析研究0℃界限温度积温的时空变化,不仅有助于进一步认识新疆热量分布和变动情况,而且对于作物及其品种的合理布局、气候资源的合理开发和利用等具有重要意义。

Abstract: By using systemic observation data of 88 meteorological stations in Xinjiang from 1961 to 2005,several elements were analyzed,including the first and the last dates of which daily mean air temperature steadily passed 0℃,days between the first and the last dates,the spatial and temporal change of accumulate temperature.The results showed that accumulate temperature of Xinjiang and all regions had a tendency of increase,it increased 43.1℃ per decade in all regions in Xinjiang.Tacheng Basin had the highest value with 89.6℃ per decade on average.Days between the first and the last dates in all regions had a tendency of increase.The first date changes differently: it's delayed in north Xinjiang(except Yili valley),Tianshan moutain and Hami basin.It's advanced in south Xinjiang,Yili valley and Naomaohu basin,and the last data in south Xinjiang,Yili valley and Naomaohu basin tended to postpone.By analyzing the spatial and temporal change of accumulate temperature of 0℃,it not only could help to know the distribution and change of heat resource in Xinjiang,but also had important meaning for reasonably distribution of crop and developing and using climate resource.

Key words: Xinjiang, 0℃ critical temperature, Accumulated temperature changes
