中文摘要：

当前城市水空间体系规划,多以人为划分的行政管理区域为系统单元展开,与自然条件下所形成的水文生态系统单元的尺度不对等、边界不整合,导致规划成果不能体现自然水文生态系统的整体性和层次性。针对上述问题,研究提出将小流域单元作为城市水空间研究与管理的最佳地域尺度;并在厘清小流域生态水文过程的基础上,将城市小流域划分为小流域、次小流域和集水区等层次,以此建构出完整的水系和湿地空间体系;最后,以州河小流域内的达州市经开区为例,对该方法进行验证。本研究有助于为城市水安全、水生态、水环境、水资源等问题的综合求解,提供因循水文过程、契合自然生态环境的物质空间保障,为城市水空间系统化、生态化建设提供思路。

英文摘要：

In the city water space system （CWSS） planning, the system unit always is administrative area, which is different ~ith the natural eco-hydrology system units in the scale and boundary, resulting in the absence of the integrity and hierarchy existing in the natural eco- hydrological system. Pointing to the problem, the watershed which consists of three levels （watershed, sub-watershed and catchment）, is proposed as the best scale in the CWSS planning. Based on the watershed, the eco-hydrology process of CWSS can be understood easily, so the integrated CWSS, including waterway and wetland system, can be eco-reconstructed better, In the planning of Dazhou economic- technological development area in Zhou watershed, we established the detail CWSS planning method based on the scale of watershed. The research should help comprehensively solve the problems of city water security, water ecology, water environment and water resources in spatial domain, and provide ideas for the eco-construction of CWSS.
