水文学知识介入风景园林设计的空间机制分析框架

随着风景园林设计对水文分析要求的提升,设计师在设计实践中,往往存在着无法准确理解与应用水文学知识的情况。在引入“空间机制”概念后,发现明晰景观空间(自变量x )与景观功能(因变量y )之间的因果关系是解决该问题的关键,而基于水文学知识的水文过程分析则是研究特定景观空间与景观功能因果关系的有效途径,因此构建了“景观空间变量-水文要素变量-景观功能变量”的分析框架。应用该框架,将河流流速相关的水文学知识转译为设计语言,并分析河流流速与河流廊道空间变量和景观功能变量之间如何相互影响,从而提出不同功能目标导向下的河流廊道景观设计策略,并提炼出水文学知识向风景园林设计语言转译及应用于实践的一般途径。

A Spatial Mechanism Analysis Framework forApplying Hydrological Knowledge to LandscapeArchitecture Design

With the improvement of hydrological analysisrequirements in landscape architecture design, designers oftenhave difficulties in accurate understanding and application whenapplying hydrological knowledge to design. After introducingthe concept of "spatial mechanism" in the research, it is foundthat clarifying the causal relationship between a specificlandscape space (independent variable x ) and landscape function(dependent variable y ) is the key to solving this problem, andhydrological process analysis based on hydrological knowledgeis an effective way to understand this causal relationship.Therefore, the framework of "landscape spatial variables -hydrological element variables - landscape function variables" isconstructed. Using this framework, the hydrological knowledgerelated to river flow rate is translated into space design language, andanalyze how the flow velocity of the river interacts with the landscapespatial variables and landscape functional variables of the rivercorridor, and then the landscape design strategies of river corridorsunder the guidance of different functional objectives are proposed.Finally, a general way of translating hydrology knowledge intolandscape design language and applying it to practice is extracted.Keywords: landscape architecture; landscape architecture design;
