Structure and dynamic characteristics of Cyclobalanopsis glauca secondary forests
Cyclobalanopsis glauca,one of the main species of the subtropical region in southern China,plays a vital role in the stability of the southern ecosystem.Through the method of sample survey and data statistics,the age structure of the population was analyzed,and the static life table of the population was compiled.The mortality,survival and disappearance rate curves were analyzed.By means of time series prediction and population quantitative dynamic method,The population structure and dynamic characteristics of Cyclobalanopsis glauca in natural secondary forest were revealed.The results showed that the dynamic change index of Cyclobalanopsis glauca was 0.010 3,indicating that the population was stable.The survival curve was similar to Deevey-Ⅱ,and the mortality of each age group had similar mortality.Time series prediction The results showed that the number of young plants decreased gradually and the long-term stability of the population was stable.Therefore,the appropriate artificial measures were to keep the natural regeneration and population stability of Cyclobalanopsis glauca population in the future.
