摘要
该文选取和县2015年9月1日至2016年8月31日为研究对象来探究该地区土壤的温度特征。结果表明,浅层地温受气温的影响较大,气温与之决定系数高达0.9381,随着土壤深度加深,地温随着气温的变化而变化响应减弱。受气温的影响,10月至次年2月份表现为土壤热力由深层补给浅层,3—9月份相反。相邻月际之间土壤温差的变化相对显著,且具有较强的季节性差异。强降水后深层土壤温度有所升高,可能的原因是土壤水将表层土壤中的热量往深层迁移,从而增加了深层的土壤温度。
In order to understand the characteristics of soil temperature,the study was carried on in Hexian,China. It is found that soil temperature variation range decreased with the depth of soil,indicating that the deeper the soil,the more stable the soil temperature. We can infer that when the seasonal transtition the soil temperature changed sharply. However,the inter-monthly soil temperature variation was changed with the season shifting. The soil temperature is diversity in heavy rain at different communities,and the rainstorm can decrease the soil temperature rapidly.
