Preface

In the late 1960s, Western developed countries such as Germany and Switzerland have begun to apply ecology principle to civil engineering experiments to restore damaged riparian ecosystems. After the 1990s, the concept of river ecological restoration has become a trend worldwide, and some countries have taken the lead in the research and practice of “restoring river life”. The river governance method of “wrapped” the river with concrete ignores that the river is also a living body, which has been generally rejected by various countries, and the ecological restoration of the river has become an international trend.
    The construction of an ecological city is to follow the principles of ecology and the laws of ecological economy, with the construction of the urban ecological environment and social development as the core. Through unified planning and comprehensive construction, the ecological construction, environmental protection, natural resource utilization, ecological restoration, economic development and urban and rural construction in the urban area are organically combined. Cultivate ecological landscape with blue sky, clear water, green ground, and beautiful scenery; induce an overall, harmonious, self-reliant, and open ecological civilization; incubate economically efficient, environmentally harmonious, and socially applicable ecological industries; build a civilized ecological community where man and nature coexist harmoniously. Ultimately realize the sustainable development and high degree of unification of regional economic, social and ecological benefits. Urban ecological water conservancy planning is based on the sustainable development of ecological city construction. According to the principles of ecology, following the laws and requirements of ecological balance, the planning of a water conservancy system that meets the virtuous cycle of the city and the sustainable use of water resources is established. Water conservancy construction and water-related activities are aimed at protecting, improving and restoring water ecological environment in cities and ensuring water ecology and water resources safety. Urban ecological water conservancy planning is a special plan of urban planning and an infrastructure in urban planning. It must not only obey the overall urban planning, but also enrich and perfect the overall urban planning. Therefore, we must not only focus on urban development planning, but also urban ecological water conservancy planning. Only in this way can we achieve sustainable human development.

前 言

20 世纪 60 年代后期，德国及瑞士等西方发达国家已开始将生态学原理应用于土木工程以恢复受损河岸生态系统的试验研究。 90 年代以后，河流生态修复理念在世界范围内成为趋势，一些国家率先开始了“恢复河流生命”的研究和实践。忽略河流也是生命体，将河流用混凝土“包”起来的河道治理方法，已被各国普遍否定，河流生态修复已经成为国际大趋势。
      生态城市建设就是遵循生态学原理与生态经济规律，以城市生态环境建设与社会发展为核心，通过统一规划、综合建设，把城市区域内生态建设、环境保护、自然资源的合理利用、生态破坏的恢复以及区域内社会经济发展与城乡建设有机地结合起来，培育天蓝、水清、地绿、景美的生态景观，诱导整体、合谐、自生、开放的生态文明，孵化经济高效、环境和谐、社会适用的生态产业，建设人与自然和谐共处的殷实、健康、文明向上的生态社区，最终实现区域性经济效益、社会效益、生态效益的可持续发展和高度统一。城市生态水利规划是以生态城市建设的可持续发展为目标，按照生态学原理，遵循生态平衡法则和要求，建立起来的满足城市良性循环和水资源可持续利用的水利体系的规划，旨在城市保护、改善和修复水生态环境并确保水生态和水资源安全的水利建设与水事活动。城市生态水利规划是城市规划的专项规划，是城市规划中的一项基础设施，它既要服从城市总体规划，又要丰富和完善城市总体规划。因此，我们在城市建设中不能只注重城市发展规划，还要注重城市生态水利规划，只有这样才能实现人类的可持续发展。
