Embodiment Construction

[0046] Taking the rationality evaluation of China's urban development pattern as an example, the specific application of the technical method of the present invention is further described.

[0047] Taking China as the implementation case area and 2010 as the time node, the USR model was used to diagnose the rationality of China's urban scale structure pattern, the UKR model was used to diagnose the rationality of China's spatial structure pattern, and the UFR model was used to diagnose the rationality of China's functional structure. The HL model diagnoses the rationality of the national urban development pattern in 2010. Specifically, the application includes the following steps:

[0048] 1. Establishment of a diagnostic index system for the rationality of the national urban development pattern

[0049] According to the index system in Table 1, the population, city size ranking, built-up area, GDP, total employment population and employment population of 20 industry types of...

Abstract

A technical method of diagnosing rationality of city spatial patterns includes the following steps: 1, constructing an index system comprising a master target layer, a sub-target layer, a factor layer and a divisor layer; 2, after standard data processing, using an analytic hierarchy process and an entropy weight process to determine a weight of the divisor; 3, constructing HL comprehensive diagnosis models for rationality of city developing patterns, the models comprising a scale pattern USR diagnosis model, a spatial pattern UKR diagnosis model and a function pattern UFR diagnosis model; 4, using a fuzzy membership grade function process and a linear weighting summation process to calculate a rationality index for each sub-model; and 5, dividing cities into a highly reasonable city, a relatively reasonable city, an intermediate reasonable city, a lowly reasonable city, and an unreasonable city according to HL comprehensive indexes. The comprehensive diagnosis index system provided by the present invention has universality and comprehensiveness, and has availability and effectiveness when evaluating the data. The completed system evaluating method enables the calculated result of the rationality indexes of the urban developing patterns to be more accurate, and achieves a more scientific evaluation of the urban developing patterns.

Description

technical field [0001] The invention provides a technical method for the rationality diagnosis of urban spatial pattern, which synthesizes the rationality of urban development pattern at the levels of the country, region, province, and urban agglomeration from the scale structure, spatial structure, and functional structure of the urban system. Diagnosis can provide comprehensive, objective and scientific decision-making basis for the comprehensive evaluation of urban development pattern. Background technique [0002] The urban development pattern refers to the urban spatial configuration form and specific order formed on the national land space based on the national resource and environment pattern, economic and social development pattern, and ecological security pattern, with orderly scale and scale, obvious spatial linkage effect, and reasonable division of functions. The urban development pattern includes the urban scale structure pattern, the urban spatial structure pat...
