Problems solved by technology

[0006] The present invention aims at the current lack of objective, comprehensive and quantitative evaluation methods for geographical conditions. The purpose of this invention patent is to propose a comprehensive index for monitoring geographical conditions ( National Geographic State Comprehensive Index, NGCI) method, in order to achieve automatic monitoring of geographic national conditions comprehensive index, to avoid the effect of human subjective factors in the evaluation of geographic national conditions comprehensive state

Embodiment Construction

[0046] Technical scheme of the present invention is based on following two points:

[0047] 1. Selection of components of the comprehensive index of geographical conditions

[0048] As mentioned in the background, existing index component selection techniques have limitations such as strong subjectivity and failure to consider the correlation between components, making it necessary to develop component selection techniques based on optimization theory. To this end, the present invention provides an optimal selection method based on principal component analysis (PCA). This method uses principal component analysis (PCA) to select the main components of the geographic national conditions thematic domain for the geographic national conditions comprehensive index.

[0049] Theoretically speaking, there should be weak correlation or no correlation between the components of the comprehensive index of geographical conditions, and such an index structure is the most reasonable. Accor...

Abstract

The invention provides a method for monitoring a composite index of geographical national conditions, which comprises the following steps: selecting construction components of the composite index of the geographical national conditions; confirming the weighted value and establishing the influence degree of each component on the composite condition of the geographical national conditions; monitoring the composite index of the geographical national conditions; estimating the composite condition of the geographical national conditions; and providing an indicating and monitoring method for quantitative evaluation on the composite condition of the geographical national conditions so as to avoid objectivity and uncertain factors of man-made estimation. The method for monitoring the composite index of the geographical national conditions is simple, is strong in comprehensiveness and objectivity, is suitable for objective, comprehensive and quantitative evaluation on the condition of national geographical national conditions or regional geographical national conditions, and can be used for providing scientific data support for decisions.

Description

technical field [0001] The invention belongs to the technical field of automatic monitoring of geographic and national conditions, and in particular relates to a new monitoring method for comprehensive index of geographic and national conditions. Background technique [0002] The comprehensive index is a quantitative indicator that reflects the status of a specified field in a country or region, and is a quantitative, intrinsic and comprehensive indicator used to judge the stage of development of a specified field in a country or region. Since geographic national conditions are a new type of comprehensive national condition system, there is no scientific, quantitative and comprehensive evaluation method at present, and there is an urgent need for indicators that can scientifically, objectively and quantitatively evaluate the comprehensive situation of geographical national conditions. [0003] On the other hand, extensive attempts have been made in many thematic fields to de...
