中文摘要：

以广西西江黄金水道开发规划为例,采用层次（AHP）分析法,提出了由经济区位、水运能力、综合交通条件和产业发展潜力等4个方面13个因素所构成的评估指标体系,预估西江黄金水道开发规划对区域内各城镇的差异性影响,发现其具有轴向集聚性和轴线分异性,因而不同次区域应因地制宜地采用不同的城镇化发展战略。同时,本文对反映不同的城镇发展战略与重点的＂金三角＂、＂倒T字型＂和＂中心辐射型＂等三种空间结构进行综合比较,认为广西城镇体系规划原来所提出的＂中心辐射型＂空间结构已不适宜,而＂倒T字型＂模式和＂金三角＂模式各有优缺点,可将它们进行组合集成,构建特色鲜明、疏密有致的城镇体系。

英文摘要：

China has been rapidly constructing its major transportation infrastructure such as high-speed railway and highway, waterway, which have great impacts on regional city development and urban system planning, so it is urgently needed to explore the impact e- valuation method and to conduct empirical case studies. By taking Xijiang waterway devel- opment as a case study with AHP method, this paper firstly puts forward an impact evalu- ation index system consisting of 13 indexes in 4 aspects such as the improvement of region- al economic location, the improvement of water transport capacity, the improvement of re- gional comprehensive transportation conditions and the potential of industrial develop- ment. Then, the differential impacts of Xijiang waterway exploitation on city development in sub-areas have been evaluated hy using this index system. The results are shown as fol- lows. （1） The impacts of Xijiang waterway development on city development are strongly concentrated on the axis of Xijiang riverside and are also different in different sub-areas. Thus, different sub-areas within Xijiang economic region should adopt different urbaniza- tion development strategies. The eastern sub-area should rapidly develop the city corridor along the Xijiang mainstream, the central sun-area should actively develop the metropoli- tan areas such as Nanning Metropolis, and the upstream sub-area should mainly develop characteristic cities. （2） Xijiang waterway development also has strong impacts on the re- gional urban system and its spatial structure planning. By conducting comprehensive com- parison among the three spatial models such as the ＂ Central Radiation＂ model, the ＂ Golden Triangle＂ model and the ＂Reverse-T＂ model pattern, this paper concludes that the Central Radiation＂ model, which is proposed by the ＂Guangxi Urban System Planning （2006-2020） ＂, is no long suitable, and the latter two models or their combination are more suitable.
