摘要 运用分形思想和系统理论分析了长春地区各城镇40年间(1949~1988)的异速生长关系及其分形演化过程,发现城镇体系时空关联的分维图式随着社会经济环境具有空间分异特征和时段阶变性质:只有具备健康的社会经济环境,城镇体系才能形成良好的分形性态。文章从时空关联的角度验证了城市系统的适应性假设和地理分形结构的优化猜想。

Abstract:A study is made of allometric growth of urban system by means of fractal idea,and the allometric coefficient is proved to have some sense of fractal dimension. The allometric relationship between the ith city and the jth th city in an urban system is given as QiQjTij and Tij=αi/αj=di/dj,where α is the growth Tij=αi/αj=di/dj coefficiet of Q,and d is its dimension. If one of di and dj is a fractal dimension,Tij can be regarded as of fractal dimension. If one of di and dj is a fractal dimension, αij can be regarded as of fractal dimension. Based on the theory advanced by the authors,the allometric course of Changchun urban system from 1949 to 1988 is analysed using gross value of industrial output as variable,and it is found that ①An urban system meets allometric relationship with fractional dimension under some given conditions;②Sometimes,the fractal allometric relationship degenerates;③Last but not least,allometric models and properties change with social and economic environment. One of the important conclusions is that the fractional allometric growth as an optimum relationship is to the course of urbanization what fractal structure as an optimum organization is to urban spatial system.
