Osmanthus is a traditional Chinese cultivation of aromatic plants, it has been one of China's traditional top ten flowers listed by the National Ministry of Light Industry, listed as China's important economic species, its fragrant flowers quiet, sweet, fragrant and elegant, Osmanthus fragrans extract, net oil in the international spice market exclusive products, can be used in the preparation of the High Flavor, balms and other industrial perfumers, at the same time the osmanthus also has high ornamental value, medicinal value, and a variety of other purposes, and therefore to carry out ecological studies of the sweet-scented osmanthus Osmanthus fragrans wild population osmanthus secondary forest community formation mechanism, effective protection, the protection of biodiversity and osmanthus development and utilization of resources are all important. In this study, the number of statistical methods of Changting County pinnacle Walled Scenic osmanthus population and its component characteristics were analyzed and discussed. Interspecific association of dominant populations, population structure and dynamics, population life process analysis, different growth Branching Patterns of the developmental stages of the population, configuration differences in the populations of different habitats, populations of seedlings under different light conditions configuration differences. The results are as follows: (1) 2 × 2 contingency tables, analysis of variance, the association of x to 2 test, Ochiai index of secondary forest communities the of Changting County pinnacle Walled Scenic osmanthus dominant populations of ligneous species quantitatively analyzed. The study results show that: the community overall interspecific correlation showed no correlation in the early stages of community succession, because most of the plants are just entering the community, the vast majority of the population is still growth and development, and is still on resources and the environment allocation and utilization stage, competition between attachment relationship is relatively weak, showed a weak relationship between the various plants. Only 10 pairs have a significant positive association, 10 pairs have a significant negative association, 210 kinds in 190 pairs did not reach a significant level, the coupling coefficient between various pairs, some expressed mutual probability larger , also reflect some kind between the pairs of the existence of a positive or negative relation, The Community physical characteristics should be combined to analyze whether there is a relationship between the plant species, while the mutual effect may also change over time varies. (2) adjacent grid method, spatial sequence instead of the time-varying \The diffusion coefficient of C aggregation index CI, the average congestion * index measured the spatial distribution pattern of the sweet-scented osmanthus populations, and to explore the osmanthus from changes in the spatial pattern of seedlings, saplings and adult plant. The results showed that the plots osmanthus Population size class structure roughly inverted J-type, that have a larger number of seedlings, saplings and a few large strains, the population is in the growth stage, the population mortality peak in saplings to tree growth in. Of osmanthus population distribution patterns in different lots is not consistent, which is outside ecological environment factors combined result of the biological characteristics of the population itself. The population distribution pattern of different developmental stages largely by the cluster to random aggregation degree from large to small, tend to weaken the seedlings and saplings for the cluster distribution into a tree for random distribution. (3) according to the method of \draw the survival curve. The results showed that the The osmanthus population survival curve is typical of Deevey-Ⅲ type curve slope larger populations of early survival sharp decline with age class environment sieve selection intensity, and the role of outside interference, caused by
