【摘要】 河道作为城镇生态系统中最具活力的因素之一,是城镇文化传承的物质载体,在社会经济发展中发挥着极其重要的作用。但是传统的水利工程设计理念注重河道行洪航运功能,较少考虑城市的整个生态系统、人的心理等方面的环境需求。导致河道普遍存在淤积严重、河水污染、“三化”(河流形态直线化、河道断面规则化、护岸材料硬质化)等现象,严重影响居民的生活质量和身体健康。因此,寻求一种能满足多方面需求的治理措施并充分发挥城市河道的多种功能的近自然河道设计,对于城市建设的重要性就显得日益迫切。本文站在规划的角度将河道生态整治的理论、技术与具体工程相衔接,提出浙江省城镇近自然河道设计方法及模式。主要研究成果包括以下四个方面:(1)通过实地踏勘、拍摄照片、测量、向当地居民发放调查问卷等方式进行调研,系统、全面、真实地总结出目前浙江省城镇河道存在的问题。(2)通过分析现代人们对河道的功能要求及传统人类对其利用的方式,初步系统地总结了人类对河道的改造行为主要有以下几方面:保育、复育、完全复原、创造、明智利用以及自然化。(3)明确了应从流域的尺度进行河道的生态整治,通过深入和定量的研究对浙江省城镇近自然河道生态整治的理论、技术与相关实践做了较为完整的综述。(4)将浙江省近自然河道进行分类(山溪型、平原型、沿海型、村镇集居地型),并针对不同河道类型提出建设策略及具体措施,并进行实践验证,以期为类似于浙江省的其他河道建设提供借鉴。更多还原

【Abstract】 As the most dynamic factor in the urban ecosystem, river is the material carrier of urban cultural heritage. It plans an extremely important role on social economic development. But the traditional hydraulic engineering design concept usually focuses on river’s flood shipping functions, with little consideration of environmental demands from aspects of the whole urban ecosystem and human psychological. It brings up the universal existence of severe sedimentation, water pollution and“three conversions”(river shape straightening, river section regularization, revetment materials hard electron particle materialization) , and also severely affects household living quality and health. Therefore, search for various needs control measures and give full play to multiple functions of urban rivers , which is becoming increasingly urgent in urban construction.This paper presented near-natural river design approach and model in Zhejiang province from the standpoint of planning combing with the theory, technology and concrete engineering of river ecological restoration. There are four major research areas:(1)By using the spot reconnaissance, photography, measurements and questionnaire investigation to local residents, the author summarized the current issues of urban river in Zhejiang province systematically, comprehensively and factually.(2)By analyzing river’s functional requirements to modern people and canal utilization of ancient people, the author preliminarily and systematically summarized human behavior on river channel rehabilitation. It included conservation, restoration, full restoration, creation, wise-use and naturalization.(3)Clearing from the standpoint of basin, the author did an in-depth and quantitative study on the theory, technology and concrete engineering of near-natural river’s ecological restoration in Zhejiang province to drafts a systematic review.(4)Classifying near-natural river in Zhejiang province for the first time, (stream, plain, coastal and settlement), the author presented construction strategy and concrete measures according to different types of near-natural river, and practical proof, in order to provide reference for other similar rivers.更多还原
