The Probe into the Multi-Objective Landscape Design of Urban River Based on Ecological Security--With the Planning of the Weihe River Landscape Zone in Xi'an-Xianyang as an Example

摘要

China is in a period of rapid urbanization. Many riverfront cities are trying to realize the river-crossing development and may cause serious issues with urban expanding, such as environmental devastation and rural transformation. Thus, we must take the multi-objective as the orientation in landscape design of urban riverside areas. In planning the landscape area 50km in length along the Weihe River between Xi'an and Xianyang, we have proposed an idea of establishing the National Weihe Wetland Park in the entire area, by using the principle of partitioning the park into regions, limiting and linking the nodes in urban spaces and clusters of different functions along the riverside, to achieve the multi-objective of combining protection of ecological environment , renewal of urban area and continuation of historical context in landscape design. This paper discusses the goals of landscape design in urban riverside areas, analyzes the feasibility of establishing the National Weihe Wetland Park and details the systematic structure of the park and the methods of its construction.
