Landscape Design Of Tongxi Lake In Changsha

At present,the research on the construction of artificial lake ecosystem at home and abroad is only in the preliminary stage.The ecological indicators are used for analysis and evaluation.So far,there is no unified evaluation index and method.The comprehensive evaluation of urban artificial water landscape is mainly based on the comprehensive evaluation of urban landscape water itself by using some fuzzy comprehensive evaluation theory.TongXi Lake is a newly built artificial lake.Its construction has a positive effect on promoting the construction process of Dawangshan International Tourism Resort.It can improve the comprehensive utilization rate of water resources in the area,and can also improve the drainage standards in the area and make the ecology within the area.Environmental functions are clearly restored and improved.After the completion of the Tongxi Lake and the water system in the area,it can reduce the soil erosion in the area,beautify the regional environment,maintain the stability of the water surface all the year round,and create a pleasant waterfront landscape space,providing a good environment for people's life and leisure.The development of tourism in Changsha City and Xiangjiang New District is of great significance.Based on relevant cases at home and abroad,the upper-level planning,surrounding environment,road traffic,human resources,regional water quantity,pollution sources,etc.are analyzed,and the theory of landscape ecology and sponge city is used to analyze the water quality of the lake and the overall landscape demand of the area.Through the technical measures of water volume calculation,internal and external pollution source control measures,and research on waterfront waters around the lake,through the lake hydrology,water quality protection and landscape design,the lake landscape area and the water landscape integrating water purification and landscape functions are realized.The lake regulates the drainage,ecological conservation,beautification of the environment,leisure and entertainment and other functions,so that the harmonious development of the lake and surrounding sites,and the integration of landscape and urban development.The project design process comprehensively considers the landscape effect after completion of Tongxi Lake and the need for water surface,water quality stability and regional drainage safety.The engineering measures adopted can meet the construction needs of Tongxi Lake,and conclude with operational design measures and practical applications.Technology provides a certain reference for the construction of similar artificial lake landscapes.
