Embodiment Construction

[0042] Step 1: Data Acquisition and Collation of the Third National Land Survey

[0043] 1.1 The third national land survey data acquisition: from the urban natural resources and planning department.

[0044] 1.2 Data collation of the third national land survey: select the land use classification and summary data in the land survey data (see figure 2 ), imported into ArcGIS, and used the clipping tool of ArcGIS to capture the old urban area of ​​Wu'an City as the research area.

[0045] Step 2: Construct a complete traffic network model of Wu'an City

[0046]2.1 Data preparation for the construction of the traffic network: Obtain the road network data of the old urban area of ​​Wu'an City through OpenStreetMap open source maps and crawler tools, and improve the road network system of Wu'an City through data comparison and calibration, combined with actual research conditions. The road network data structure mainly includes the fields of road alignment, road grade, and road ...

Abstract

The invention discloses a land diversity metering method based on territorial survey data, and the method comprises the steps: carrying out the mixed diversity index calculation of various types of lands for a residential land according to the range of a walking life circle through employing a novel data source, i.e., third-time national territorial survey, and carrying out the spatial aggregationanalysis of an analysis result of the diversity index; and determining the priority time sequence of land adjustment planning by using the distribution result of the local Moran indexes. According tothe method, the latest land classification data of land survey is combined, the land mixing diversity calculation method considering the daily life range of residents is provided, the diversity spacedistribution aggregation result is used as the basis of the land utilization planning adjustment time sequence, the subjectivity and randomness of decision making are avoided, and the scientificity of decision making is improved.

Description

technical field [0001] The invention belongs to the technical field of urban planning, and in particular relates to a land use diversity measurement method based on the data of the third national land survey. Background technique [0002] With the continuous development of my country's urbanization process, the advantages of mixed urban land use are becoming more and more obvious. In recent years, governments all over the country are formulating different mixed land use plans according to their own actual conditions. The mixed use of urban land can drive the development of multiple industries, alleviate the pressure of urban population living, increase the attractiveness of talents, and enhance the vitality of the city. The existing achievement patent land mix analysis mainly uses urban POI data or mobile phone signaling data, and according to the traditional urban land use classification standard, conducts land use diversity analysis and evaluation within a certain range e...
