PARAMETER IDENTIFICATION OF STOMATAL CONDUCTANCE MODEL FOR THE PREDICTION OF TRANSPIRATION RATE ON TYPICAL SUMMER DAYS BASED ON THE RESULT OF FIELD MEASUREMENT OF TRANSPIRATION RATE OF ZELKOVA SERRATA

The latent heat transfer associated with tree transpiration is one of the influences trees on surrounding physical environment and it important to predict rate correctly in order evaluate urban water budgets. When are planted as a countermeasure against warming street canyon design, necessary influence commonly typical summer days accurately rather than that particular certain day. Various prediction models for stomatal conductance have been proposed. In this study, widely road side day at time high accuracy, predicted Penman Monteith method incorporating Jarvis type model. tha t can variation single scale model most used today. Zelkova serrata, species roadside Japan, was clarified using long term measurement result. Based result, parameters proposed by Ward et al 23,24) were identified days.
