A method, device and storage medium for measuring the interaction of urban agglomeration elements

Abstract

The invention provides a method, equipment and storage medium for measuring the interaction of urban agglomeration elements, according to the urban element index data of each spatial unit in the urban agglomeration and the spatial distance and time distance between each spatial unit; The spatial distance and time distance of each independent variable are weighted on the urban element index data corresponding to each independent variable, and the geographical space-time weighted neural network model is established, and the interaction measurement value of the interaction index is obtained through training. The method provided in this embodiment captures complex nonlinear relationships in different geographical spaces by constructing a time-space weighted neural network to measure the time-space proximity of elements between cities, and makes up for the lack of perspective of time-space correlation and the neglect of cities in traditional analysis methods. The lack of spatial influence between the interior and the city helps to adjust the spatial layout and structure of the urban agglomeration by using the interaction mechanism between elements, and assists the coordinated service and comprehensive decision-making of the urban agglomeration.

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
