摘要

針對潮汐式魚菜共生系統之水耕部分，本文以能量平衡法建立一套監測模型，其以累積蒸發散量對氣候數據的迴歸分析來求取出作物生理特徵係數，並以其來監測植物在不同階段的生長狀況。模型以濕球溫度作為空氣濕度相關參數，並用濕球降差值來簡化系統與環境之顯熱傳導率的估算；另外亦應用創新求取方法所得出之濕球溫度的計算公式來方便此監測模型的應用。基於模型之生物環境監測系統不同於過去以視覺觀察方式，除能提供量化數據外，亦可將來應用於遠端無人化管理監控。

This article proposes an energy-balance-based regressive model to evaluate the plant physiology in the hydroponics part of an aquaponics system. It can monitor the growth of plant at different stages and assess whether the plant is in a healthy and suitable state according to the accumulative evapotranspiration mass of water and the environmental climate data. The model uses the wet-bulb temperature as a humidity-related parameter and uses the wet-bulb depression to simplify the estimation of the sensible heat conduction between the system and environment. To facilitate the calculation of wet-bulb temperature, the novel formulae for calculating wet-bulb temperature has also been introduced. The model-based bio-environmental monitoring can provide the quantified information beyond vision and can be applied to remote unmanned management and monitoring.
