Several sub-models were investigated to formulate a model for estimating the budgets of heat, water vapor, and carbon dioxide within vegetation and soil, that is -(1) a turbulence closure model for moist air within vegetation, (2) a radiation transfer model within vegetation, (3) a stomatal conductance model, (4) a root water-uptake model, (5) a simultaneous heat and water transfer model within soil, (6) a root respiration model, and (7) a soil respiration model.The model for the budgets of heat, water vapor, and carbon dioxide within vegetation was verified in this study. And the heat budget within vegetation was numerically investigated in detail. The followings became clear from the investigation: (1) A great deal of radiation absorbed by leaves is released by transpiration. (2) Long-wave radiation is not omitted in estimating the heat budget in comparison with short-wave radiation.

研究了几个子模型，以形成估算植被和土壤中热量、水汽和二氧化碳收支的模型，即：（1）植被内湿空气的湍流闭合模型，（2）植被内辐射传输模型，（3）气孔导度模型，（4）根系吸水模型，（5）土壤中热量和水分同时传输模型，（6）根系呼吸模型;（7）土壤呼吸模型。并对植被内部的热量收支进行了详细的数值研究。研究表明：（1）叶片吸收的大量辐射是通过蒸腾作用释放出来的。(2)与短波辐射相比，长波辐射在估算热收支时没有被忽略。
