The richness center of the Theaceae plant species under study is located in the mountainous area of north Guaugdong (22.5°N, and 112~115°E). These plants species exhibited significant longitudinal difference (P=0.0012), and latitudinal variation (P=0.0049). Canonical Correspondence Analysis showed the distribution of plant species could be explained by caloric factors and moisture factors, and MAMI (mean annual minimum temperature) was the key factor determining the distribution pattern of Theaceae plant species richness in the study area.
