specific Embodiment

[0133] Specific embodiments: below in conjunction with accompanying drawing and example to present embodiment, comprise the steps:

[0134] 1. Factor considerations: In this example, a certain province is taken as the research area, and seven prefecture-level cities (city A, city B, city C, city D, city E, city F, and city G) of a certain province are taken as the research objects. The following urbanization elements are used to calculate the flow of urbanization elements among the seven cities in a certain year (January 1 to December 31).

Abstract

The invention discloses an urbanization element flow distribution method based on neighborhood and grid, solves the problem that flow and distribution of urbanization elements are not analyzed in the prior art, and belongs to the field of earth science. The method comprises the following steps: S1, acquiring urbanization factor flow data of each city at an initial moment in a set time period, and carrying out standardization and dimension reduction processing on factors; S2, determining a flow path of the elements according to the shortest distance, the minimum passing time and the minimum cost; S3, determining an element flow distribution amount and an element flow direction according to a difference value of the element values among the cities; and S4, under the influence of constraint conditions, calculating a flowing result of each urban element according to the determined flowing path in a set time period. According to the method, the influence of various constraint conditions on element flow in the actual situation is comprehensively considered, so that the scientificity and the accuracy of a calculation result are improved.

Description

technical field [0001] The invention relates to a flow distribution method of urbanization elements based on neighborhoods and grids, belonging to the field of earth sciences. Background technique [0002] The flow of regional factors refers to the displacement of the flowable regional economic development factors in the regional space and between regions. Factor flow and regional development promote each other and go hand in hand. The flow of factors promotes the development of regional economy and society, which in turn promotes the division of labor and trade within the region, further accelerating the flow of factors. At the same time, a region is an open system, as long as there is an imbalance in the development of regions, there will be a flow of interregional elements. As a node in the flow of elements in geographical space, cities have inflows of population, capital, technology, knowledge, information, etc., and corresponding outflows. The connection between citi...
