Zoning method of urban overall height control based on factor comprehensive evaluation

Abstract

The invention discloses an overall city height control partition method based on comprehensive divisor evaluation. According to the overall city height control partition method based on comprehensive divisor evaluation, required data materials are extracted from relevant legal planning results such as overall city planning first and are imported to a digital technology platform and converted to impact factor control parameters according to a height control mathematic model built after researches, height control values of all street units are obtained, standardized correction is further conducted on the height control values according to a Saaty method, and the final height control partition result is obtained after conversion is conducted on the height control values. The overall city height control partition method based on comprehensive divisor evaluation is based on objective and rational analysis and comprehensive and overall evaluation modes, the data materials are easy to obtain, and therefore the city heights can be effectively controlled in a macro-level mode.

Description

technical field [0001] The invention belongs to the technical field of urban planning, and in particular relates to an urban height control technology based on factor comprehensive evaluation. Background technique [0002] Urban height control is an important part of urban spatial form control, which reflects the degree of agglomeration of urban space in a three-dimensional scale, and is also an important means of shaping spatial landscapes such as urban interfaces and urban skylines. In the process of rapid urbanization, urban height control is not only affected by the visual experience of the landscape, but also an intuitive reflection of the objective law of urban economic and social development in terms of spatial form. [0003] The existing methods for urban height control mainly include the following: [0004] 1. Perspective method [0005] Determine the specific observation viewpoint and angle of view, obtain the spatial perspective of the research area through hand...

AI Technical Summary

Problems solved by technology

[0013] For urban height control, traditional general methods rely solely on empirical judgments, visual evaluations, etc., lack scientific data support, and the research scale is limited. It is mainly based on the urban scale of the district level, and it is difficult to conduct comprehensive analysis from the overall macro scale of the city.

On the other hand, some planning practices also try to use digital platforms to conduct auxiliary research on urban height control, but most of them start from the perspective of the spatial landscape effect of certain specific urban spatial landmarks, and it is difficult to grasp it from a macro perspective

Or the introduced influencing factors are too complex to reflect the inherent laws of urban economic and social development
