风景园林水环境参数化设计研究

Water environment is one of the important contents of landscape architecture planning and design. It is mainly made up of two parts：water landscape and water resource. At present, combining qualitative and quantitative, regulating water resources scientifically to achieve win-win situation of water resource utilization and water landscape optimization is an important issues of landscape architecture planning and design, which is needed further research. Guiding by System theory, This topic focus on the planning and design method of synchronous optimization of water resources and water landscape in landscape architecture. Firstly, on the basis of the qualitative interpretation of the water resources distribution mechanism in the natural conditions, the quantitative research methods are introduced. Secondly, water landscape and water habitat digital model is constructed by using ArcGIS platform construction, and parameterized model is constructed by digital technology, then, using the algorithm describes the dynamic relation between water resource distribution and water landscape construction. Thirdly, landscape architecture water environment digital graphics is formed based on Civil3D platform, which is practicability. Through interpretation and simulate the water landscape and water habitat in natural state, the study explores the method of protecting, restoring, restructuring the order of landscape water environment. The method is not only can achieve the synchronous optimization of water resources and water landscape in landscape environment, but also can enhance the scientific, accuracy and work efficiency of landscape architecture design.
