Based on the analysis of ecological process of Platycladus orientalis pure forest in limestone mountain of Xuzhou, the reasons of ecological degradation of Platycladus orientalis pure forest were found, and the direction, principle and succession method of artificial promotion of Platycladus orientalis pure forest succession were put forward. For tree species, explain the long-term, phased and continuous ecological forest concept of artificial succession, and gradually establish the concept of multi-tree species with more and more multi-function and more stable functions of harmonious forest plant community.
