Embodiment

[0096] Select two typical areas in the central urban area of ​​Shanghai as the research case, divide them into 17 blocks, and use the traditional urban spatial form eigenvalue calculation method and space syntax to calculate the plot ratio, mixed land use ratio, connection value and The four representative urban morphological eigenvalues ​​of the global integration degree are calculated, and the results are shown in Table 1. It can be seen from Table 1 that the values ​​of the eigenvalues ​​of each block are quite different, and it is difficult to evaluate the quality of the urban form of the block through the comparison of each eigenvalue.

Abstract

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.

Description

technical field [0001] The invention relates to a method for comprehensive evaluation of urban block space form based on fuzzy mathematics theory, belonging to the technical field of urban planning. Background technique [0002] Urban form reflects people's cognition of urban spatial form and its relationship with surrounding areas. The theory of western urban morphology has a very complete theoretical basis. Among them, the typology research theory represented by the Italian-French School mainly regards urban blocks as the research scale and focuses on the study of urban texture (tessuto urbano); the environmental behavior theory represented by Kevin Lynch Emphasize that good urban form should include: vitality and diversity, accessibility (open space, social services and work), control (space volume close to the human body), feeling (recognizability), flexibility and social equity, etc. A series of performance indicators. In urban planning, ensuring that the form of spa...
