摘要：利用实测的地温和土壤含水量数据模拟石榴-小麦间作系统的土壤热通量。结果表明:利用地温和含水量数据模拟的土壤热通量值与热通量板实测结果一致性较高;土壤热储量是地面热通量的重要组成部分,忽略土壤表层热储量并以某一深度处的实测热通量值代表地面热通量的方法误差很大;石榴-小麦间作系统内的地面热通量存在显著的水平空间变异性,小麦覆盖区域地面热通量几乎一致,均显著小于石榴株间裸地。
In this study, the soil surface heat flux of Punica granatum-Triticum aestivum intercropping system was calculated based on the measured soil temperature and water content. The results indicated that soil heat flux estimated from the soil temperature and water content well agreed to that measured with the heat flux plate. The soil heat storage is an important component of soil surface heat flux. If the measured heat fluxes at some layer below the soil surface is taken as the soil surface heat flux and the soil heat storage is ignored, large errors was introduced. The calculated soil surface heat flux at different points in the Punica granatum-Triticum aestivum intercropping system showed that there was significant spatial variation. Similar heat flux results were found at the two points between the megranate rows, and the values significantly less than that at the bare-soil.
