摘要

从耗散结构的视角,港城系统是以外部自然与社会经济环境为支撑,以港口系统与城市系统时空耦合为基础的耗散结构系统。分析其演进历程,港城系统通过大小"涨落"向着有序、高级方向发展,运用综合发展度从时间序列纵向评价系统综合发展水平,运用系统熵从要素构成横向测度系统有序状况;对比分析两者演变规律,综合发展度和系统熵具有很强的相关性。通过解析系统熵结构,进一步探究和理解港城系统发展的演变机理,港城系统有序发展本质是港城系统及港口系统、城市系统的负熵流输入。结合江苏省连云港,对1996~2008年29项指标377个原始数据进行处理,合并成开放程度熵、社会实力熵、设施环境熵和经济实力熵,得出引发连云港港城系统涨落的负熵流输入时间与输入方式,在理论上总结了港城系统有序演进规律。

Abstract

From the perspective of dissipative structure, port-city is a system of dissipative structure supported by external environment of nature, society and economy, based on coupling between systems of port and city spatio-temporally.According to the analysis of its evolution process, while the negative entropy input from the external environment, the system will be able to maintain the order and develop towards an orderly and senior direction through fluctuations of its size.The article vertically evaluated the comprehensive development level of the system in time sequence, and horizontally measured orderly condition using system entropy from elemental composition.By comparative analysis, the comprehensive development level and system entropy are of great relevance.Further studying the structure of system entropy, we can understand the evolution mechanism and the orderly development essence of port-city system which lies in negative entropy stream input of port-city system, city system and port system.Taking Lianyungang city in Jiangsu Province, China, for example, merging the raw data of 29 indicators in 1996-2008 into the entropy of openness, the entropy of social power, entropy of the facilities environment and entropy of economic power, the article derived the input time and method of negative entropy flow which cause fluctuations of port-city system of Lianyungang.Based on above the empirical study, the article theoretically summarized the general law of orderly evolution of port-city system.
