檫木种群基面积增长规律研究

A Study on Growth Law of Dominance of Sassafras tsumu Hemsl Population

应用有限空间种群增长的Logistic模型、张-Logistic模型、刘-Logistic模型、自适应新模型及改进Logis-tic模型研究了檫木种群基面积增长规律,并运用改进单纯形法进行最优拟合,拟合结果表明,自适应新模型比其它种群增长模型更符合檫木种群增长的实际增长趋势。

The growth law of basic area of Sassafras tsumu Hems1 population was studied by the methods of Logistic model, Zhang - Logistic model, Liu - Logistic model, new self - adaptive model and modified Logistic model. And a new model was optimized from the modified simplex method, the optimized results show that the new self - adaptive model is more suitable than other models to simulate the actual growth trend of Sassafras tsumu Hemsl population.
