摘要
在草原生产中，植物生产和动物生产之间存在着很大的矛盾。植物生产具有明显的季节性，而家畜对牧草的需要量相对稳定。任继周教授提出的孝地季节畜牧业理论倡导有计划地淘汰家畜，有计划地利用牧草，以充分发挥暖季牧草生长的优势，使牧草尽可能多地转化为畜产品。系统动力学适宜于研究具有复杂反馈和动态特性的系统问题，被称为战略与决策的“实验室”。它从系统的微观结构入手，确定系统的反馈机制，进而模拟与分析系统的动态行为，得出解决问题的多种方案。通过建立草地季节畜牧业系统动力学仿真模型，证实了季节畜牧业理论在草原生产中的指导意义，通过模型仿真，作出了合理控制畜群的方案，对实现草原生产的科学管理有一定参考价值。
In grassland productivity,there is a great conflict between plant productivity and the animal one. Plantproductivity is obviously seasonal,but the livestock’s needs of grass is relatively stable. The theory ofgrassland seasonal livestock farming(GSLF),advanced by Professor Ren Jizhou,suggests that we shouldeliminate animals and use grass in a planned way ,to give full play to the superiority of grass’s growing inwarm seasons,to transform it into animal products as many as possible. The system dynamics(SD)isappropriate to study the systematic problems,which have characters of feedback and dynamic,so it is calledthe laboratory of strategy and decision. It begins with the microstructure of system,determines thesystematic feed back mechanism,simulates and analyses the dynamic behavior of system,and at last getsseveral projcts of solving the system problem,In this paper,by establishing the SD model of GSLF,wehave proved that the theory of GSLF can direct the grassland productivity.By the simulation.we got theprojects of controling the quantity and structure of livestock,which has some reference to scientificmanagement of grasslandproductivity.
