Sustainable Study on Rural River Landscape Based on the Eco-Priority Principle: A Case Study of Landscape Design for the River Yaxi

Abstract

Accompanying the increasingly conspicuous homogeneity in urban and rural development in the process of China's contemporary urban development, the rural river landscape is largely copying the landscape construction techniques available to urban rivers, causing several inappropriateness. This paper argues that rural river landscape design has two core demands. First, to achieve sustainable development of rivers via regeneration of natural landscape based on the Eco-Priority Principle. Second, to arouse viewers' emotional return to the river landscape by following the design principle of localness. Taking the River Yaxi of Yaxi Town, Gaochun District, Nanjing City as a case study, this paper presents the application process of rural river landscape in its township planning and design, and summarizes its sustainable regeneration methods under the eco-priority principle as follows. Firstly, make interpretation for natural ecological conditions of rivers based on present situation survey, apply centralized and detailed analysis on such basic elements as height of normal water level, water quality and surrounding situation of the site in recent ten years, and understand the historical memory of local residents for River Yaxi through questionnaire survey. Secondly, address the flood discharge specific to the existing rivers under the eco-priority principle, realize landscape regeneration by treating river revetments and arranging pumps, etc., and based on the confirmed node type of landscape design as per space atmosphere and historical imprint, adopt three design strategies of retention, extraction and derivation. Finally, while fully considering the ecological sustainability and emotional return of river landscape, satisfy the modern lifestyle needs.
