Abstract: The study on the structure and dynamics of C.glauca populations was carried out at hills around West Lake, Hangzhou, with the methods of plant population ecology. On the basis of census of all individuals of the populations at different plots, the structure and dynamics of the populations were described. The result showed that C.glauca populations were stable intermittent populations, while the spatial patterns followed contagious type which changed with size classes of the populations. It was found that seedling or sapling class showed contagious type, while the small, middle and big tree classes exhibited radom types, reflecting the spatial patterns of the populations changed with the time during its development. Additionally, the seed and clonal regeneration or propagation of C.glauca populations in different habitats were studied and discussed, together with their ecology strategies. According to the results above-studied, the dynamic characteristics or adaptive mechanism of C.glauca populations was discussed respectively.
