Spatial Distribution of Cratoxylum cochinchinense Population

In 2016, sample plots were established in concentrated distributed Guangzhou and Taishan, Guangdong province by typical sampling method. Investigations were carried out on DBH, crown diameter, tree height, clear bole height of C. cochinchinense tree with height >1.3 m, and ground diameter crown diameter and tree height of C. cochinchinense tree with height <1.3 m. The result demonstrated that that there were 122 plant species, belonging to 49 families and 96 genera. Vegetation stratification of the communities was obviously as follows: shrub layer (41 species) > tree layer (40 species) > herb layer (29 species) > interlayer plant (12 species). The surveyed C. cochinchinense population showed aggregation distribution in different plots. Aggregation of C. cochinchinense was more at shady slope. Spatial distribution C. cochinchinense population changed from aggregation to even, indicating scattered distribution with age.
