Research On Digital Terrain Design Of Landscape Architecture Based On Rainwater Harvesting Balance

At present,the comprehensive utilization of water resources and the construction of conservation-oriented garden green space have become a hot issue of common concern.Among them,rainwater collection and utilization has been an important research content in landscape architecture for many years.In urban park green space,topographic design and construction are the key factors to collect and utilize rainwater resources scientifically and reasonably.In this paper,firstly,starting from the advantages of digital design,such as scientificity,visualization and dynamics,through literature induction and case study,the advantages,necessity,design principles and objectives of digital landscape architecture terrain design are systematically sorted out;secondly,the relationship between rainwater collection and utilization and terrain is explored by studying the factors affecting rainwater collection and utilization,and the structure is constructed.The parameter system of digital terrain design based on rainwater harvesting balance is proposed.Finally,the specific workflow of digital landscape terrain design based on rainwater harvesting balance is proposed.The digital terrain design is divided into three stages: digital site analysis,digital terrain design,evaluation and optimization of design scheme.Combining with the landscape planning and design project of Yuxi River Eco-Park,aiming at the balance of rainwater collection and utilization and earthwork,and using digital analysis technology,the site topography is modeled and analyzed digitally,and the topography is designed scientifically and reasonably.The feasibility of the digital topography design method based on the balance of rainwater collection is demonstrated by an example.In a word,the digital landscape landform design method provides a new idea and method for the research of rainwater collection and utilization,and further expands the design strategy and method of rainwater collection and utilization in landscape architecture.
