为分析城镇化土地利用中典型线状地物交通运输用地的空间分布多样性特征,以郑州市为研究对象,提取不同时期遥感影像中的交通运输用地数据,将多样性理论与方法应用到交通运输用地空间分布多样性格局研究中,具体分析其空间分布与城镇建设用地、坡度等影响因素间的关联性.研究表明:①空间分布多样性指数与传统评价指数间相关性高,其中空间分布长度指数可作为描述交通运输用地空间分布及数量特征的重要指标;②近年来郑州市交通运输用地发展主要集中在郑州市区、中牟县和新郑市,且空间分布逐渐均匀,巩义市、登封市等研究区交通运输发展滞后;③郑州市交通运输用地空间分布多样性受城镇建设用地与坡度空间分布的综合影响,其中受坡度因素影响较大.%In order to analyze the space distribution characteristics of typical align feature traffic land , Zheng-zhou is selected as the research case .The traffic land use data of the study area is extracted from remote-sensing image in different times .The study is conducted using diversity theories and methods to analyze the spatial diversity distribution pattern characteristics of traffic land .The transportation land spatial distribution characteristics and the correlation among its influence factors such as urban construction land and slope are also analyzed .The correlation is specifically analyzed by multiple and partial correlation coefficient .Results show that there is a strong relation-ship between MSHDLI index and traditional evaluation indexes .MSHDLI index can be used as an important index to describe the spatial distribution and number features of the land transportation .In the recent years , the develop-ment of transportation land has mainly concentrated in Zhengzhou city , Zhongmu county and Xinzheng city .But the traffic land progresses solely in Gongyi city and Dengfeng city .The spatial distribution of transportation land in Zhengzhou is affected comprehensively by urban construction land and slope .Among the rest , it is greatly influ-enced by slope factor .
