Study on the populations regeneration dynamics of Pinus armandii in Xiaolongshan Nature Reserve
摘要
Abstract
The static life table of Pinus armandii population in the Xiaolongshan Nature Reserve in Gansu was compiled based on the population life table and theory of survival analysis using the size class structure represented by DBII class and smoothing out technique. The size class structure, curves of mortality rate, vanish rate,survival function of the P. armandii, as well as the regeneration dynamics, mortality and causes of seedling were analyzed. The results were as follows: P. armandii population size class structure were developing, characterized early growth, medium stability and later recession; the whole life process of the population had demonstrated three death peaks,of which the mortality of seedlings coming to be low and stable later, was relatively high. Consistent with the natural dynamic rule of populations, it also showed the significance and effect of "Natural Forest Protection Project"; the study indicated the dynamic and change trends of P. armandii population were crucial for both the ecological monitoring and the for-est protection applied in the reserve.关键词
