随着我国城市建设的发展、社会经济的繁荣和人们对所生活的城市环境要求不断提高， 以及城市化新月异的发展，城市排水系统已经成为城市建设的一项重要内容，受到了城市 建设者们的高度关注。各个城市建设者们对其自身的城市排水系统有着不同的理解和探究， 实施的效果也是千姿百态、各有不同。这其中有着成功的经验，也有着不足之处。 本文首先对城市排水系统的概念范畴与涵义进行了探讨，对城市排水系统的理念提出 了自己的理解，对赣州市中心城区排水系统提出了具有针对性的理念、意义、原则及要求。 其次，通过对城市设计相关理论的借鉴和排水系统的特性分析，对赣州市中心城区排 水系统设计进行了探讨，提出了针对赣州市中心城区排水系统可行性研究的基本思路、总 体定位、总体架构与分区、分系统等。通过对排水系统的理解，以及各个城市实施以来的 经验教训总结，结合赣州这个城市的特点及特色，通过调查研究、理论分析以及规划实践， 针对赣州中心城区当前城市建设突飞猛进，城市面貌日新月异，如何完善城市功能、方便 市民出行，在排水系统方面做了具有针对性的分析研究及理论结合实践的探讨，就如何解 决赣州市中心城区排水做出了一定的纲要性的可行性研究。 关键词，排水系统； 防内涝；可行性研究；赣州市中心城区；II Abstract As China's urban development, socio-economic prosperity and people live in the urban environment of increasing demands, as well as the development of different urban crescent, urban drainage system has become an important part of urban construction, urban construction has been who have great concern. Builders of their own cities and urban drainage systems have different understanding and explore the effect of the implementation is varied and different. Which has a successful experience, also have shortcomings. In this paper, the concept of the urban areas of the drainage system was discussed with the meaning, the concept of the urban drainage system put forward their own understanding of the central city of Ganzhou targeted drainage system proposed the concept of meaning, principles and requirements. Second, by drawing on the theory of urban design-related features and drainage systems analysis, Ganzhou central urban drainage system design are discussed and put forward for the central city of Ganzhou City drainage system feasibility study of the basic ideas, the overall position, the overall architecture and Zoning, and other subsystems. Through the drainage system of understanding, as well as various cities since the implementation of lessons learned, combined with the Ganzhou city of features and characteristics, through research, theoretical analysis and planning practice, for Ganzhou current urban development by leaps and bounds, urban look with each passing day, how urban functions, facilitate travel, the drainage system has done research and targeted analysis of theory with practice on how to solve the downtown drainage Ganzhou made some outline of the feasibility study.
