Through analyzing problems of shoal wetland and riverfront greening in Zhejiang Province,this paper took successful cases for example to propose the ideas for implementing plain greening effectively,such as "afforestation for flood control","landscaping construction is an ecological infrastructure project","plan wetland greening according to actual conditions","promote wetland greening by enhancing the cooperation among relevant departments","adopt multiple measures to enhance riverfront greening".展开更多

In urban areas, due to canalization or occupation of river, and forcible alteration of course of rivers, river waters area has been reduced. Natural capacity of rivers is seriously lacking, and the ecosystem services of rivers are gradually weakening. For planning, design and construction of urban landscapes, the concept of ecological restoration must be applied to protect and rationally utilize river landscapes. This paper takes the landscape belt of Huangshui River in Doba New City of Xining as an example to study the Huangshui River. Based on the theory of river course restoration, a “dynamic growth” river restoration system is established, and the restoration process of nature itself is as little as possible. In order to improve the water quality of Huangshui River, control the flow velocity and build the ecological environment, a set of perfect and self-repairing system is created for Huangshui River.展开更多
