黄山松种群数量动态研究

针对有限空间种群增长的逻辑斯谛模型的缺陷, 本文应用广义的逻辑斯谛曲线研究了龙栖山自然保护区黄山松种群数量动态, 并指出了黄山松在不同林型下和同一林型不同密度下的断面积最大增长速度的径级范围。结果表明, 广义的逻辑斯谛曲线能很好地拟合黄山松种群数量动态规律, 从而为黄山松的生产和经营管理提供了理论依据。

Study on quantitative dynamics of Pinus taiwanensis population.

Based on analysing the shortcomings of the logistic model which is a limited space growth model for population , the paper deals with the quantitative dynamics of Pinus taiwanensis population in Longxi Mountains Natural Reserve by a generalized logistic curve , and points out the highest growth rate at breast-height diameter range in different comunity types of Pinus taiwanensis forest and in pure forests with different densities .The results show that generalized logistic curve do fit the quantitative dynamics of the population .This study provides a theoretical basis on the production and management of Pinus taiwanensis .
