Study On Plant Landscape Design Of Fluctuating Zone In Kaixian Reservoir Area Of Chongqing

While large-scale water conservancy projects bring great benefits to power flood control and navigation,the fluctuation zone,as the product of water conservancy projects and an important part of the ecological environment of the reservoir area,plays an important role in the ecological environment of the reservoir area.At present,there are some problems in the fluctuation zone,such as the deterioration of ecological system,serious water pollution,the crisis of urban security affecting the stability of revetment,and the possibility of outbreak of epidemic diseases.And prevention and control of down with the ecological environment problem is the national economic and social development,protect the ecological environment is very necessary and urgent task,is to carry out the human-oriented scientific development concept and the basic requirement of building a harmonious society,is the guarantee of the surrounding people to live and work in peace and contentment,and sustainable economic and social development,building a well-off society "life project","art project".In the period of vigorous ecological construction,it is an effective practice to study the plant landscape design of the fluctuation zone using the multi-disciplinary basis to solve the ecological problems of the fluctuation zone.This study adopts literature review,field investigation,comparative analysis methods Comparing related research results at home and abroad,through field investigation and research,from the perspective of engineering,ecology and plant physiology,this research studies the plant landscape of the subsidence zone in Hanfeng lake reservoir area,Kaixian county,Chongqing,and explores the plant landscape design and ecological system construction of the fluctuation zone.This paper summarizes the design principles,design requirements,design contents and technical means of the plant landscape construction in the fluctuation zone of HanFeng Lake through the plant landscape design of the fluctuation zone of Hanfeng lake.The design principles of suitability,ecology,engineering combined with nature and landscape optimization are the preconditions for the design of fluctuation zone,and the basic conditions to be followed in the process of governance and design.Hydrologic conditions,selection of revetment types and location are the basis of the design.Design principle is the premise that the fluctuation zone to take a design,the basic condition that should follow in management,design process.Design requirements are the basis of design.Hydrological changes,engineering forms and materials,site location and land use properties have restrictions and requirements on the design and selection of plant landscape in the fluctuation zone.In terms of design content,it meets the requirements of upper planning.The overall design part is connected to the planning,and the zoning is also featured according to the positioning of the planning area,and is connected to the surrounding land in an orderly manner.The technical problems mainly lie in the solution of the interdisciplinary,the choice of plant species and the reasonable connection of the nature of land conditions.Summarize the plant species in different water level areas,such as areas with elevation of 171.00?172.00m or above,such as pool fir,swamp oak,etc.In the area with an elevation of 170.00?172.00m,emergent plants such as reed and cattail can be selected;in the area with an elevation of 169.00?171.00m,floating-leaf plants such as Gordon euryale and Rhizome can be selected(which need to be harvested regularly).Based on the engineering practice of the fluctuation zone of Hanfeng Lake in Kaixian County,Chongqing,this paper provides practical experience in planting mode and plant selection for the construction of the plant landscape similar to the fluctuation zone in the future,and provide the reference to solve the problem of fluctuation zone management in the future.
