摘要
针对我国城镇河道存在的行洪能力不足、水体污染严重与生态环境退化等问题,提出了基于生态的城镇河道整治与河流环境修复的基本概念、原则。根据我国城镇河道整治的实际要求,以恢复河道生态功能、改善水体环境与创造滨水景观为目标,从河道线形、河道断面与护岸、生态系统、景观需求与生态环境修复等方面对生态河道整治与环境修复方案进行了分析,其中河道线形一般应按照原有天然河道走向进行布置;河道断面一般可设计成复式断面和梯形断面;护岸形式建议首先采用自然生态护岸,其次是人工生态护岸;景观设计时要因地制宜、突出文化特色;生态环境修复的主要措施包括人工增氧、人工湿地、生态浮岛等。
For the problem of inadequate flood discharge capacity, serious water pollution and ecological environment degradation from urban river, the basic concepts and principles of urban river training and environment rehabilitation based on ecology were proposed. According to actual requirements of our country urban river training, making restoration of river ecological functions, improve water environment and create a waterfront landscape as the goal of programs, river remediation and environmental restoration were detailed analyzed and designed from the aspects of fiver linear form, river section and bank protection, ecosystem, landscape requirements and ecological environment restoration. River linear general should be arranged in accordance with the original natural towards; river section was generally designed as a double-cross-section and a trapezoidal crosssection; revetment form was be proposed as natural ecological revetment first, followed by ＇artificial ecological revetment; landscape design should satisfy local conditions, highlighting the cultural characteristics; environmental rcmediation measures included artificial aeration, artificial wetlands and ecological floating island.
