The reasons for the phenomenon that air temperature becomes lower after the removal of the observation field in Rugao are analyzed in this paper, considering factors such as environmental conditions, weather process, and earthiness. The results show that: this attributes to many factors, and some are more important,(1) Environmental change of observation field is one of the important reasons for the lower air temperature. (2) Geological background like soil parent material is one of the conditions for temperature difference. (3) Cold air directly and advantageously impacts on the presence of temperature difference.The analysis reveals that: the phenomenon of lower temperature after the removal of the observation field in Rugao naturally reflects the actual condition of the atmosphere.%针对如皋观测场搬迁后气温偏低的现象,本文对产生这种现象的原因从环境条件、天气过程、土壤土质做了专题分析,结果表明:这种现象是多种因素共同作用的结果,其中最主要的是:(1)观测场环境变化是形成气温偏低的重要原因.(2)观测场所在地的土壤母质等地质背景是形成气温差异的条件之一.(3)冷空气的直接影响为气温差异提供了有利的背景.经分析揭示出:如皋观测场搬迁后的气温偏低现象是更自然地反映了大气自然状况.
