Abstract: From agricultural vegetation, clay-mineral assemblage in soils and history of disappearance of tropical fauna, it is suggested that central-southern Guangxi, central Guangdong, south-eastern Fujian and northern Taiwan should be included in tropical zone, known as Northern Tropics. These areas are centers of production of tropical fruits such as banana, lichi, mango etc. in the country. The prevailing cultivation system is double-cropping rice and winter sweet potato or corn. With intensive bio-chemical weathering, the dominant clay mineral in soils is kaolinite. These facts show that the dominant landscape in these areas is tropical. Therefore, these areas should not be designated as"Soutn-Subtropical". Study on historical data shows that during the Tang and Song dynasties(7th—12th century), large groups of typical tropical animals like elephant, crocodile and peacock could be seen here. This further supports the conclusion that these areas belong to tropical zone. Literature from Hong Kong and Taiwan have also been quoted to show that Shenzhen, Hong Kong and North Taiwan are within the Tropics.
