基于信息理论的生态网络灵敏度分析

将信息理论与物流模型的研究挂接 ,定义了生态系统的信息熵和信息流量。以各分室输出量占总体的份额作为系统选择该分室的概率。通过对系统聚合度和冗余度的分析 ,推导了二者对各分室的灵敏度。对黑龙江省双城市双城镇永和村的物流模型进行了灵敏度分析。计算结果表明 ,籽粒和土壤分室对系统的稳定性起重要作用 ;而调整畜牧业的结构 ,改变农肥的投入量等 ,可以有效地改善系统的物流情况 ,使系统向良性循环

Analysis on the basis of the sensitivity of ecological network of the theory of the information

This text has hung and receives the research of the theory of the information and material flow model,has defined the information entropy of the ecosystem and flow of information.Account for the probability that chooses to divide the room as the system of total share with all of outputting amount of room.Through getting degree and redundant analysis of total share with all of outputting amount of room.Through getting degree and redundant analysis of degree together to the system,have derived the two to every point of sensitivity of room.Have carried on sensitivity analysis with the material flow model of the village to a pair of a pair of cities and towns in city in Heilongjiang Province forever,The result of calculation indicates,seed one and soil divide the room and play an important role to the stability of the system;Adjust structure of animal husbandry,change agricultural fat input amount waits,can improve the systematic material flow situation effectively,Make the system turn towards benign cycle.
