低影响开发下的城市绿地规划方法——基于数字景观技术的规划机制研究

Urban Green Space Planning Method Based on Low Impact Development: Research on Planning Mechanism under Digital Landscape Technology

针对建成环境水绿关系,深入解读了低影响开发的科学内涵,从水绿规模、组成结构和空间布局3个层面探讨基于水绿耦合原理的城市绿地规划机制。具体论述了数字技术支持下的城市绿地规划方法及流程,构建了"机制分析-空间模拟-格局生成-规划校验与方案比选"全过程数字化的城市绿地规划方法。并分别以城市总体、城市片区和城市街区3种尺度条件的实践案例为对象阐明低影响开发绿地规划方法的应用,为科学的城市绿地规划研究与实践提供参考。

Based on the relationship between water and green space in built environment,this paper deeply interprets the scientific connotation of Low Impact Development,and constructs the urban green space planning principle of Water-Green Coupled Model from three aspects that of scale,composition and spatial arrangement.Supported by digital technology,this paper discusses the methods and processes of urban green space planning,and constructs the planning method supported by digital technology in the whole process of"mechanism analysis,spatial simulation,pattern generation,and planning verification and scheme comparison".And the application of this method is discussed by taking the practice cases of three scale conditions of overall urban,urban area and urban block as research objects,which provides reference for scientific research and practice of urban green space planning.
