三明市茶树气候条件分析及气候区划

Climatic Condition Analysis and Climatic Regionalization of Tea in Sanming

对三明市茶树生产的气候条件分析结果表明 ,降水、光照及平均温度、积温等条件基本能满足茶树生产的需要 ,制约茶树生产的主要因素是冬季的极端最低气温 ,以此为区划指标建立气候区划模型 ,利用地理信息系统和Arcview软件制作分布图 ,并结合三明市茶树生产的实际情况 ,将茶树生产分为 3个生产区域 :乌龙茶为主绿茶为辅区、绿茶为主乌龙茶为辅区和绿茶与乌龙茶并重区 ,并提出茶树生产趋利避害的措施。

An analysis was conducted of the climatic conditions of tea growth in Sanming. The results show that the essential conditions, such as precipitation, sunlight, average temperature,accumulated temperature, etc, in Sanming can meet the needs of tea growth. The major factor restricting tea growth is minimum air temperature, based which a climatic regionalization model was built. Utilizing GIS and Arcview, in combination with the practical situation of Sanming, tea planting in Sanming can be divided to three areas: oolong tea complemented by green tea secondarily, green tea complemented by oolong tea, green tea and oolong tea area. Some countermeasures for utilizing climate resources and avoiding damages were put forward.
