AI Technical Summary

Technical Problem

Existing methods for calculating floor area ratio fail to respond to dynamic changes in urban operations, resulting in a disconnect from the actual situation. They suffer from single-dimensional analysis, lack of standardized calculation rules and automatic verification mechanisms, leading to inefficient planning schemes and a high susceptibility to errors.

Method used

By constructing a correlation model and calculation rule base for multi-source data, and combining dynamic influencing factors, the initial benchmark plot ratio is dynamically corrected and verified in multiple dimensions. A quantitative correlation relationship is established, an adaptive adjustment strategy is output, and dynamic updates are performed throughout the entire life cycle.

Benefits of technology

It has achieved a quantitative correlation between plot ratio and urban operation indicators, improved the accuracy and adaptability of calculations, ensured the scientific nature and sustainability of planning schemes, and solved the problems of static lag and manual dependence of traditional methods.

Abstract

The invention relates to the technical field of city planning, and particularly provides a city planning plot ratio automatic correction method and system, and the method comprises the steps: collecting multi-source data of a target plot to construct a basic data set and a correlation model, outputting the correlation relation data of the plot ratio of the target plot and city operation index quantification through the model, establishing a calculation rule base on the basis of the basic data set and the incidence relation data; calculating an initial reference plot ratio by combining the spatial feature parameters of the target plot and user input parameters based on a rule base, introducing dynamic influence factors to correct the initial reference plot ratio, and outputting a preliminary result; eliminating invalid results through multi-dimensional checking for the preliminary results, and outputting a final scheme containing an adaptive adjustment strategy; and dynamically updating parameters of the model and the rule base according to the development full-life-cycle feedback data. According to the method, automatic and dynamic correction of the plot ratio is realized, the calculation accuracy and suitability are improved, and the method is suitable for plot ratio planning correction of various urban plots.
