Abstract: Aimed to approach the correlations and the mutual adaptability between the landscape pattern and plant community structure in Xiamen urban parks, the landscape pattern indices (average patch size, patch density index, and landscape diversity index) and the plant community structure indices (forest area ratio, species diversity, and proportion of native species) were selectedto quantify the landscape pattern and plant community structure in the parks, and the mutual Pearson’s correlation coefficients were analyzed. In earlier constructed artificial parks, tree species were rich, with uniform collocation and with rational allocation of native species and exotic species. In later constructed artificial parks, tree species composition was simple, and the proportion of native species was low. In semi-natural parks, natural forests were well maintained, with rich tree species and high proportion of native species. Compared with artificial parks, semi -natural parks had larger average patch areas, lesser patch types, and lower landscape fragmentation and landscape diversity. The average patch size was positively correlated with the forest area ratio and the proportion of native species, while the landscape diversity index had a negative correlation with the forest area ratio, indicating that there existed a certain spatial correlation between plant landscape pattern and community structure in Xiamen urban parks.
