工程化措施下的瓯江滨水景观设计

我国的河道综合治理项目起步于上世纪90年代,治理经验不足,部分综合治理项目存在许多负面影响,其根本原因在于在河道综合治理过程中只考虑了河道治理的排洪蓄水等物质功能,却忽视了滨河景观效能以及对河道的生态保护。文章以瓯江干流水生态系统保护与修复总体规划项目为例,通过分析、归纳等方法提出在河道综合治理基础上的滨水景观设计理论。

Environmental River Engineering

In the past, river engineering works have often caused channel instability and adversely affected the river's conservation and amenity value. Recent guidelines have advocated a more natural approach to river engineering practice which retains habitat diversity within the river system. While a more natural approach is desirable, geomorphological guidance is required to ensure that the advocated changes are feasible and sustainable, both in the long and short term. The key requirement for sound environmental river engineering is a basic understanding of the natural processes controlling channel shape and dimensions. Examples are given in the paper to illustrate how such knowledge can be used to (a) stabilize rivers, (b) design environmentally-acceptable and stable flood-alleviation schemes, and (c) restore previously canalized rivers. The basis of the geomorphological input in the assessment and design process is a river survey which determines the factors controlling channel characteristics and how it will respond to planned changes.

Ecological Design Across Interface: Ecosystem Restoration of Pengxi River/Reservoir in Three Gorges Reservoir Area,Chongqing

Riparian zone is a typical ecotone that connects terrestrial and aquatic ecosystems. At the same time, environmental stress magnifies here and the natural regulation of rivers is extremely active. In other words, the most dynamic and vibrant interactions between rivers and landscapes occur in riparian zones. However, the construction of dams and the operation of reservoirs have turned many riparian zones into river/reservoir alternation interfaces, influenced the shaping of hydrological and water environment, and the basin ecosystem as well. By introducing the definition and ecological characteristics of river/reservoir interface, this paper proposes the strategies and technical framework for the ecological design of river/reservoir interface. By studying the ecosystem restoration project of river/reservoir interface of Pengxi River in Three Gorges Reservoir Area of Chongqing, which emphasizes the comprehensive element design, structural design, functional design, and process design, this paper aims to provide a reference for related research and practice on river ecosystem restoration. The results of ecological performance analysis showed that the restored ecosystem of the Wuyangba river/reservoir interface has an obvious increase in habitat type diversity and biodiversity, a strong ability of plant communities to adapt to seasonal water level fluctuation, and an improvement in purifying non-point source pollution. The project demonstrates the coordination and symbiosis of interface ecological restoration and waterfront landscape construction and optimization. The project offers an innovative effort in exploring ecosystem restoration design and practice of river/reservoir interfaces. The design strategies and framework can be a reference for other ecosystem restoration cases that are affected by water level fluctuation in river/reservoir interfaces.     

Rescuing Big Rivers Damaged in Industrial Civilization

Large rivers with beautiful landscapes were dreamlands to the author. However, every time upon his arrival to riversides, he was shocked for the heavily polluted rivers that are dirty, messy, and smelling. Engineered dikes and dams made of concrete and steels for a greater height and hardness are built by cities along rivers. As more highways and railways built along rivers, vehicles run at a faster speed, scaring any life who wants to or has to access the water. Most of the tributaries are no longer free flow but end up as hard ditches and the water is polluted heavily. Forests and wetlands are being damaged and eroded. All of these are resulted from humans’ material desires and lack of respect for nature. Nevertheless, ecological civilization may encourage people to appreciate the beauty of nature and get a thorough understanding on river ecosystems and their services, accompanied by systematic planning and implementation of territorial ecological restoration. Moreover, laws and regulations on large river management should be put in place, and efforts should be made to break the worship of grey engineering approaches to flood control. It is expected that nature-based ecological approaches for a better resilience and sustainability in flood management can be more effective to ensure water safety.
