摘　　要：为了准确定量得到一片不规则临港产业区的产业布局方案,利用栅格化方法,将港区和目标产业用地划分为大小相同的正方形网格,以各产业之间、港区与各产业间的已知关联度确定各栅格之间的关联度,构建以所有栅格间综合关联度最大为目标的不规则临港产业区布局,最后基于栅格编号排序编写整数编码的多智能体进化算法,求得综合关联度最大的布局方案。以盐城滨海港为例,将滨海临港产业划分为50个栅格,根据规划面积确定拟发展的6种产业所占栅格数,利用MATLAB编写多智能体进化算法,设置智能体网格为20×20,以进化代数150代、200代和300代各运行10次,得到关联度最大的3种布局方案,综合关联度分别为549,550.8和555,遗传算法运行50000代的最佳结果仅为520.8,表明在定量解决不规则临港产业区布局问题上,该模型和算法具有较强的优越性。In order to accurately and quantitatively obtain an industrial layout scheme of an irregular port-vicinity industrial zone,the harbor area and the target industrial land were divided into square grids of the same size by the grid method in this study.The relevancy degree between grids is determined by the known relevancy degree among industries,harbor areas and industries,and the irregular port-vicinity industry with the goal of maximizing the comprehensive relevancy degree among all grids isconstructed.Finally,an integer-coded multi-agent evolutionary algorithm is compiled based on grid number sorting to obtain the layout scheme with the greatest comprehensive correlation.Taking the Yancheng Binhai Port as an example,the coastal port industry is divided into 50 grids.According to the planned area,the grids occupied by six industries to be developed are determined.The multi-agent evolutionary algorithm is compiled by MATLAB.The agent grids are set to 20×20 to run 10 times for 150,200 and 300 generations of evolutionary algebra,and three layout schemes with the greatest correlation degree are obtained.The comprehensive correlation degree is 549,550.8 and 550 respectively.The best result of running 50000 generations of genetic algorithm is only 520.8,which shows that the model and algorithm have strong superiority in solving the problem of irregular layout of port-vicinity industrial zones quantitatively.
