摘要
本文利用系统动力学方法和灰色系统理论,建立了盐池县草原畜群发展动态模型。通过计算机模拟,可找出控制滩羊与山羊数景发展的敏感参数。认为在控制畜群数量的同时,经济效益亦可得到提高。
In this paper, the dynamic models for livestock population in rangeland of Yanchi county were established by system dynamic method and grey system theory. With the computer process of model, several sensitive parameters such as total elimination coefficient of basal ewes,wether slaughter rate(C_6), percentage of killing Iambs (P_1)and rate of lamb fur (P_2) are found, by which, it is possible to control the development of Tan sheep and goat populations. The author considers that controlling livestosk population can raise the economic benefits.
