Method of identifying urban function area integrated with population density and landscape structure

Abstract

The invention relates to a method of identifying an urban function area integrated with population density and landscape structure. For the method of identifying an urban function area integrated with population density and landscape structure, the used data is mainly the village-level population statistical data and the land utilization data. The processing process of the method of identifying an urban function area integrated with population density and landscape structure includes the steps: a, selecting a typical road as an urban expansion axis and setting a sampling band and a quadrat; b, extracting the population density and land utilization type information of the quadrat; and c, integrating population density with landscape structure to identify an urban function area, such as an urban center area, a peripheral area and an outer suburban district. Based on the relation between urban land utilization and the landscape function, the method of identifying an urban function area integrated with population density and landscape structure can identify the urban function area by calculating the population density and an urban landscape index, thus being helpful for scientifically learning about the internal structure of a city, and promoting reasonable planning and functional configuration of the city.

Description

technical field [0001] The method belongs to the cross technical field of landscape ecology, urban geography and geographic information technology. Background technique [0002] Along with the process of urbanization, different urban functional divisions will inevitably appear along the urban expansion axis, such as urban central area, peripheral area, (isolation zone), (satellite city), and outer suburbs. At present, land use data are mostly used to distinguish urban built-up areas from non-built-up areas, and there are few studies on the boundaries between these functional divisions. [0003] In addition, the research on the internal functional pattern of the city mainly analyzes the characteristics of the functional division of labor within the city by using the population of each district and county by industry or related socio-economic indicators, and seldom studies it from the perspective of landscape. There are relatively few studies on the application of integrated ...
