不等距Leslie矩阵及其对唐家河地区大熊猫种群动态的应用

The Vary in Distance Leslie Matrix and the Application in the Population of Giant Pandas in Tang jiahe Region

本文对文献[1]即:《不等间距Leslie矩阵对卧龙五一棚大熊猫群动态的应用》的不等间距Leslie矩阵进行了详细介绍,并用这个矩阵模型对唐家河地区的大熊猫种群动态进行了研究,得到与以上文献完全相同的结论,成年大熊猫的出生率下降10%对大熊猫种群数量的影响与各年龄段的大熊猫死亡率都提高10%的影响相当。大熊猫的出生率是重要因子,决定大熊猫种群是下降或增长的出生率的门坎值在0.189与0.21之间,野外大熊猫的出生率的值究竟是多大?这决定了大熊猫种群的动态。水池模型的意叉在于将抽象化的不等间距Leslie矩阵形象化,延伸出对其它不明基数物种的种群动态预测方法。

The authors particular introduce the Vary in Distance Leslie Matrix in essay , and studied the changing development of the population of the giant pandas in Tang jiahe region, get ：he same conclusions with the essay ： There is no different in the effect to the population of the giant pandas between the fertility rate reduce 10% and the death rate improve 10%. The key factor is the giant pandas＇ fertility rate. The doorsill standard that decides whether the population of giant pandas reduces or improves is between 0.189 and 0.21. It is necessary for us to make sure the standard of the wild giant pandas fertih＇ty rate; it decides the development of the population of the giant pandas.
