Abstract: We set three plots of 40 m×40 m to study the stand spatial structure pattern at different successional stages of secondary forest with different densities of masson pine in Qiandao Lake, and took censusing of every individual and coordinate positioning. We compared and analyzed the main tree species and stand holistic spatial structure for three plots by using three structure parameters (mingling, neighborhood comparison, and uniform angle indexneighboring tree distribution pattern). The masson pine was the dominant species and presented an aggregating distribution at the No.1 plots, the rest tree species were basically scattered and the growth were seriously suppressed. Masson pine and blue Japanese oak were the dominant species and all presented an aggregating distribution at the No.2 plots, the other tree species were scattered and the growth were suppressed. Castanopsis sclerophylla significantly presented an aggregating distribution at the No.3 plots, the mingling of the whole stand was higher, the size differences of C.sclerophylla forest were small, the growth of forest was in the mean state, and the tall trees with absolute advantage lacked. The whole stand of three plots presented an aggregating distribution. The results suggested that the No.1 and No.2 plots were all in the initial stage of succession, and alternative cutting management was needed to accelerate the succession of stands. The No.3 plots had a succession with dominant C.sclerophylla evergreen broad-leaved forest, and it still would take time to be mature climax community.
