中文摘要：

选择贵阳市典型的岩溶盆地乌当区东风镇作为研究区,为了研究不同土地利用方式土壤温度变化特征,对林地、灌丛、草地、农田、温室大棚5种类型的土壤温度进行了监测.结果表明：（1）各样地白天气温呈：大棚＞草地＞农田＞灌丛＞林地,最高温度出现在14：40左右;（2）各样地土壤温度峰值较气温峰值滞后约1小时,升温时间较长,降温时间较短,且随着地表植被的减少土壤温度的日较差增大;（3）随着深度的增加,土壤温度峰值逐渐滞后,土壤温度日较差逐渐减小.早晨土壤底层温度大于表层,此后逐步转变为“下低上高”的温度态势.

英文摘要：

Diurnal variation of soil temperature of five land use patterns in Dong Feng Zhen,a typical Karst basin at Guiyang City in Guizhou Province,were observed.The results showed that different land use patterns altered the coverage and height of aboveground vegetation,which in turn changed the environment microclimate.The temperature was in the order of greenhouse ＞ grassland ＞ farmland ＞ shrubland ＞ forestland.The soil temperature was delayed by 1 h at 5 cm of soil depth.The soil temperature at the depth of 5-25cm dropped with the evolution of the communities and the soil temperature decreased with depth.
