A Study on Introduction and Culture of Taiwania flousiana in Guangdong and Its Cultural Regional Assignment

Taiwania flousiana was introduced to Guangdong in 1981. Since then, the introduction and culture trial was carried out at 12 sites. It has been proved that T. flousiana have broad ecological adaptability an introduction potential, and the plantations performed well. Compared with Cunninghamia lanceolata, its increment is greater in the northern part of Guangdong, while the increment is a little less before 7 years old from the viewpoint of the whole province. The growth of T. flousiana is affected by soil characters and tiny landform, and it is more adaptive than C. lanceolata in the land with altitude over 500 meters. The growth model of T. flousiana was built using the growth data from 12 sits and 10 environmental factors. According to climatic factors and tree growth data, T. flousiana culture region was divided into four: Ⅰ:north of Guangdong, Ⅱ: northeast of Guangdong, Ⅲ: west coastal hilly area of Guangdong, and Ⅳ: east and central parts of Guangdong. Among the four regions, Ⅰ and Ⅱ are the suitable ones for T. flousiana.
