Embodiment Construction

[0102] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0103] Theoretical basis of the present invention is:

[0104] (1) Multi-factor comprehensive evaluation model

[0105] The multi-factor comprehensive evaluation model is to systematically and comprehensively analyze the impact and strength of various factors and factors on the natural surface characteristics of the region, and then conduct a systematic and comprehensive evaluation of the natural surface characteristics of the evaluation region based on quantitative methods, reflecting the regional The difficulty and pros and cons of the natural surface for ...

Abstract

The invention discloses a characterization method of natural surface features. The method comprises natural terrain estimation, natural landform estimation, natural ground cover estimation, natural geographical condition comprehensive estimation and natural surface pattern feature characterization. According to the method, natural surface elements in regional geographical condition elements and the influence of the natural surface elements on activities of region production, life and ecological environment are evaluated through a comprehensive evaluation model. Meanwhile, a series of indexes, including patch density and diversity index and facing natural ground surface element space pattern feature characterization, are designed through a landscape pattern analysis method. The method overcomes deficiencies that when the existing regional natural surface feature computation and characterization technology is used for regional natural surface feature characterization, comprehensive evaluation models are absent, regional natural surface space features cannot be characterized, and the like. The technical scheme serves geographical condition statistic analysis work to be about to be developed within the national scale, meanwhile is the technical basis of geographical condition-oriented space-time data mining.

Description

technical field [0001] The invention belongs to the technical field of geographic national conditions statistical analysis and spatio-temporal data mining, and in particular relates to a natural surface feature characterization method. Background technique [0002] Geography and national conditions are the comprehensive expression of various natural and human elements such as topography, land cover, transportation network, and urban layout at the macro level. An important part of the basic national conditions. [0003] Geographic national conditions can be divided into multiple thematic contents such as natural surface, geographical location and ecological coverage according to the different thematic elements expressed to reflect different aspects of geographical national conditions. Among them, the natural surface mainly reflects the spatio-temporal pattern and changing characteristics of natural geographical national conditions such as regional topography, landform, land ...
