中文摘要：

综合运用回旋半径法和地理信息系统分别对河南省豫西山地灵宝市和豫东平原柘城县进行聚落与交通网络空间分布特征分析,结果表明：柘城县交通网络的长度维数（DL）为1.1659,灵宝市为1.0983,均小于2,两地均表现出交通网络密度从测算中心向周围地域逐渐递减的规律性;柘城县交通网络分枝维数（Db）为1.324,灵宝市为0.9818,柘城县较灵宝市交通网络的通达性高;柘城县聚落体系分布半径维数（D）为1.5044,灵宝市为1.0571,柘城县较灵宝市聚落体系空间分布均匀。平原县市和山地丘陵县市的交通网络与城乡聚落体系空间分布均表现出明显的分形特征。

英文摘要：

Transportation is the contact channel between urban and rural settlements,and traffic network is the material basis of urban and rural settlement system formation and evolution.Taking a hilly county and a plain county-Lingbao and Zhecheng in Henan as examples,this paper studies their special features of settlements and transportation network with the methods of cyclotron radius and GIS.The results show that the spatial accessibility of transportation network and the uniformity of settlement system which cities bring out have the fractal characteristics.The length dimension（DL）,the branch dimension（Db） of transport network,and the spatial dimension（D） of settlement system in Zhecheng are 1.165 9,1.324,and 1.504 4,respectively,while those of Lingbao are 1.098 3,0.981 8,and 1.057 1,respectively.Their DL are both less than 2,showing their density of transport network gradually decreases from the center to the surrounding area.As compared with Lingbao＇s Db,the accessibility of transport network in Zhecheng is higher.Zhecheng＇s D is greater than that of Lingbao,so the special distribution of settlements in Zhecheng is more uniform.
