Research on the Landscape Planning Strategies of Urban Water-Level-Fluctuation Zone in the Three Gorges Reservoir—Case Study of Yunyang County of Chongqing

Water-level-fluctuation zone in the Three Gorges Reservoir is the most important artificial fluctuating zone in China, with a vertical drop of 30m. It has been a worldwide problem that how to protect it ecologically, utilize it scientifically and develop it healthily. That matters the living environment of most cities in the Three Gorges Reservoir Region. In the perspective of landscape architecture, taking the urban water-level-fluctuation zone of Yunyang as a case, the study attempt to put forward the connotation and principles of its landscape planning on the basis of analysing and summarizing its characteristics (periodicity, verticality, diversity, vulnerability), contents(natural grassland, farmland, natural woodland, hardened bank, wharf, wasteland, parkland, temporary building), function(ecological function, social function) and problems(ecological environmental deterioration, river-city landscape segmentation). Emphatically exploring two aspects of land use pattern and plant landscape construction to study its landscape planning strategies, the paper is expected to construct the research framework of urban water-level-fluctuation zone landscape planning in Yunyang and other cities in Three Gorges Reservoir Region. It may also provide valuable enlightenment for living environment construction of water-level-fluctuation zone in other regions.
