摘要
以旷地、单层橡胶林及自然雨林作为对照，分析了人工雨林土壤温度及土壤热通量的日、年变化规律。结果表明：（１）土壤温波振幅减小幅度表现为旷地＞单层橡胶林＞人工雨林＞自然雨林，位相滞后则是旷地＜单层橡胶林＜人工雨林＜自然雨林。（２）地面最高温度表现为旷地＞单层橡胶林＞人工雨林＞自然雨林，地面最低温度相反，以自然雨林最高，旷地最低。（３）土壤热通量的绝对值以旷地＞单层橡胶林＞人工雨林。
It were analysed Laws of temperature variation and heat flux of artificial rainforest soil during day and year as compared with bare land,pure rubbe forest and natural rainforest.The results show:(1)extent of soil temperature fluctuation in bare land>that in pure rubber forest >that in artificial rainforest >that in natural rainforest,and the phase hysteresis of bare land<that of pure rubber forest<that of artificial rainforest<that of natural rainforest;(2)the highest surface temperature on bare land>that on pure rubber forest>that on artificial rainforest>that on natural rainforest;(3)the absolute value of soil heat flux of bare land>that of pure rubber forest >that of artificial rainforest,but their phases hysteresis appear in turn.
