3.2. Process Analysis of Bio-Climatic Indicators
Through terroir observations and social survey conducted among Uji Area tea farmers on seasonal agriculture
practices, several key factors in Ujitea cultivation can be clearly pointed out. Based on observations and survey data,
Uji tea farmers have regarded these bio-climatic factors as very crucial in the seasonal agriculture practices of Uji
tea cultivation. Thefac tors are identified through extrapolation of climatic data with social survey result, whereas
cross referencing the two factors clearly showed how temperature and soil factors are highly considered as the most
crucial factors in the cultivation process of Uji Tea.
By utilizing bio-climatic indicators derived from winegrape cultivation, similar key bio-climatic factors in Uji tea
cultivation can be translated into several important bio-climatic indicators which correspondent with the two most
crucial factors. The applicable bio-climatic indicators developed from the key bio-climatic factors would be: 1)
Helio thermal Index; 2) THSW Index; 3) Dryness Index; 4) Cool Night Index; and 5) Soil Respiration.
