The ecological conditions and the law of geographical distribution for cultivated tea plants in China

茶树是一种典型的亚热带植物 ,栽培的茶树属人工植被 .本文讨论了中国栽培茶树的生态条件及地理分布规律 .栽培茶树的地理分布不仅决定于自然条件 ,而且还决定于社会经济条件 .茶树的分布具有水平地带性和垂直地带性 .中国茶树集中在亚热带湿润气候区域 ,该区域的茶园面积占全国 90 % .在中国的中亚热带地区 ,茶树是主要的经济作物 .在丘陵山区 ,茶叶的产量随海拔升高而减少 ,但其品质在一定海拔高度范围内 。

Tea plants (Camellia sinensis (L) Kuntze) is a typical subtropical plant, It is an artificial cultivated vegetation.This paper discusses the character of ecological conditions and the law of geographical distribution for tea plants in China. The geographical distribution of artificial tea plants depends not only on the natural conditions, but on the social economic conditions.The tea plant in China has its distribution law of horizontal and vertical zonality. A subtropical zone humid climatic region of China has greatest areas of tea plantation, accounting for 90% of the total areas.It is one of the major economic crops in the middle subtopic zone of China. On the hilly lands, the yield of the tea plant decreases with the increase of elevation, and quality of the tea increases with the increase of elevation in a given elevation range.
