Population spatial pattern is the result of long-term adaptation and selection of plant population biological characteristics to environmental conditions.The study analyzes the distribution pattern of pioneer tree species in the process of ecological restoration.It is of great significance for knowing the change of species distribution characteristics and its potential mechanism.Then the study establishes 3 plots with different recovery levels in Changting County,Fujian Province;and analyzes the changes of spatial distribution characteristics of Pinus massoniana in the recovery process through field investigation and calculation of population spatial pattern index.The results show that on the whole,the distribution of Pinus massoniana population is still homogeneous,but the uniformity and aggregation intensity change continuously at different recovery stages.The distribution types of Pinus massoniana population in different life history stages are different.Small trees are clustered,while middle and large trees are mainly clustered,but gradually change to uniform distribution type with the increase of ecological restoration.
