Urban block space form comprehensive evaluation method based on a fuzzy mathematics theory

The invention discloses an urban block space form comprehensive evaluation method based on a fuzzy mathematics theory, and belongs to the field of urban planning. Aimed at the urban form assessment problem that multi-angle, multi-parameter and clear definition of good and bad standards and methods are not realized, the invention proposes to comprehensively plan a spatial intensity characteristic value and a spatial structure characteristic value by an urban form fuzzy coefficient (UFI) based on a Kaempfer-Richi environmental behavioristics theory; And by integrating the value judgment of the city morphology theory and the connotation of each characteristic value, a method for judging the quality is provided for each characteristic value index with the ambiguity characteristic so as to realize the quantitative comparison and quality analysis of the city morphology difference of the block. Results show that the UFI value has certain correlation with each characteristic value of the UFI value, local morphology and spatial integrity characteristics of the block can be comprehensively reflected, the overall experience of people on the spatial morphology of the block is expressed, and objectivity and feasibility are achieved. The invention provides an effective way for comprehensive and quantitative analysis of urban morphological characteristics.
