摘要
为实现港口群发展与生态环境相协调的目的,运用生态学中描述生物种群增长规律的Logistic模型,以大连港与营口港为例,建立港口间相互作用关系的数学模型,给出港口间稳定共生条件,并提出港口群最大生态效益模型.
To achieve the goal of harmonious development between the port group and ecological environment,the Logistic model which describes biological species growth law in ecology is used to establish a mathematical model of the interaction between Dalian port and Yingkou port.The symbiotic stability conditions between ports are offered,and the model which can create the largest eco-efficiency for port group is put forward.
