Urban agglomeration element interaction measurement method and device and storage medium

Abstract

The invention provides a city group element interaction measurement method and device and a storage medium. The city group element interaction measurement method comprises the steps that city elementindex data of all space units in a city group and space distances and time distances between all the space units are obtained; and weighting the urban element index data corresponding to each independent variable according to the spatial distance and the time distance between the spatial units, establishing a geographic space-time weighted neural network model, and training to obtain an interaction metric value of the interaction index. According to the method provided by the embodiment of the invention, the space-time weighted neural network is constructed for measuring the space-time neighborhood relationship of each element between cities, and the complex nonlinear relationship of different geographic spaces is captured, so that the defects that a traditional analysis method lacks a space-time association view angle and ignores the space influence between the interior of the city and the city are overcome; urban agglomeration spatial layout and structure can be adjusted by using aninteraction mechanism among elements, and urban agglomeration cooperative service and comprehensive decision are assisted.

Description

technical field [0001] The invention relates to the technical fields of urban planning and geography, in particular to a method, device and storage medium for measuring the interaction of urban agglomeration elements. Background technique [0002] Urban agglomeration is a relatively independent collection of urban agglomerations formed by multiple spatially adjacent cities. As an open and complex giant system, it is projected into various urban elements with corresponding functions in geographical space, such as industries, Population, transportation and ecology and many other elements. The spatial changes of various elements in urban agglomerations (population, residential areas, industrial parks, commercial areas, logistics parks, high-speed rail, highways, capital, etc.) constantly reshape the space and structure within and between cities. Therefore, measuring the spatial connection and interaction of various elements in each space of an urban agglomeration is one of the...

Problems solved by technology

[0005] In view of the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a method, equipment and storage medium for measuring the interaction of urban agglomeration elements, which overcomes the inadequacy of the measurement methods for the interaction between urban elements in the prior art. The use of single-dimensional measurement of the interaction relationship between elements leads to the defect that the measured results cannot accurately reflect the relationship between urban elements
