城市河流景观整治中的类自然化形态探析

Approx-natural form in urban river landscape eco-environment improvement

城市河流迥异于乡村田园河流和乡村溪流,在河流景观工程建设上受到城市环境、水利及生态等诸多因素的限制。结合南京滨水绿地实例和国外城市河流成功改造实例,对中国近年来城市滨水景观建设中普遍存在的滨水景观日趋硬质化、重视觉形式和肆意设置休憩空间等现状进行了调查分析,以河流本身的自然原生态价值与潜力和大众需求为前提,提出城市河流景观建设应视其所处地段环境条件进行因地因势满足城市河流的防洪功能,以期在基于生态工法下找到适当的理性实践途径,最终达到城市河流最观类自然化形态保护和恢复的目的。

The urban river was distinguished with the country river, and controlled by the urban environment, water conservancy and ecology factors in the river engineering. After studied about urban waterfront landscape design in Nanjing and abroad, this paper talked about the phenomenon of inside waterfront design, such as the harder of landscape, formality and heterogeneous space for outdoor activities. It suggested that the urban river engineering should take residents＇ day-to-day demand and the river＇s value and potentiality as the precondition, considering about urban land condition and the function of controlling the flood, catering to environment＇s endurance. Based on the ecological engineering methods, this paper is launching the purpose of protecting and restoring the approx- natural form of urban waterfront landscape, returning the environment-friendly ecological urban waterfront outdoor space to people.
