Abstract: Trends of air temperatures and urbanization impact were studied using mean air temperatures and soil temperatures at the depth of 40 cm from Chengde observation station during 1964-2007. The results show that air temperatures have rosen remarkably in Chengde over the last 44 years. Linear trend analysis shows that annual air temperatures rose by about 0.269℃ per 10 years, and 0.099℃ came from urbanization impact. Since 1980, the warmingtrend was about 0.421℃ per 10 years because of urbanization impact. Air temperature rose more in winter and spring than in summer and autumn, and the urbanization impact to the air temperature was the most important factor.

Key words: air temperature, soil temperature, urbanization impact

摘要: 用承德市单站气温和40cm地温资料进行比较,采用趋势倾向分析方法,分析了承德市1964?2007年气温变化趋势及城市化影响程度。结果表明:1)承德市近44年气温呈上升趋势,平均每10年气温上升0.269 ℃,其中0.099℃是因城市化影响引起的升温;2)1980年以来,城市化影响升温幅度达到每10年上升0.421℃;3)冬季和春季气温上升幅度较大,且城市化对其影响最为明显。
