摘要
运用分形理论对豫南地区城镇体系进行空间研究,通过分析其城镇等级规模结构、空间关联维数及牛鸦维数比和随机集聚性维数,探讨城镇体系的空间特征现状:(1)豫南地区城镇规模分布比较集中,中间位序城镇数目较多,但规模偏小;(2)城镇空间分布较集中,主要分布于一条地理交通线,城镇间的交通网络通达性优良;(3)豫南城镇体系主要以信阳为核心,呈扇形集聚性空间特征.基于上述特点,提出城镇体系发展的优化建议.
Using the fraetal theory to study spatially the town system of southern He＇ nan area, through the analysis of the urban grade scale structure, spatial correlation dimension and cow＇ s dimension ratio and random integration dimension, the current situation of urban system spatial characteristics was discussed in the paper. Results show that ： （ 1 ） the urban scale distribution is centralized, and the number of intermediate towns is much more, but smaller in scale; （2） urban spatial distribution is relatively concentrated, mainly distributed in a geographic traffic line, with good traffic network between towns ; （3） the southern He＇ nan urban system mainly takes Xinyang as the core, the fan connection space characteristics. Based on the above characteristics, the suggestion of optimization on the development of urban system were put forward.
