The second is about the simulation of urbanization assessment
[0004] At present, the detection of the agglomeration of urban and rural construction is still mainly focused on the selection of urban central areas, and there is no research on the process and trend of urban and rural development, let alone application

Embodiment Construction
[0050] Below, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0051] In this embodiment, the Bohai Rim region is taken as the case area, and based on the land use data of the Bohai Rim region in 1980, 1995, 2000, and 2010 as the data source, the agglomeration of urban and rural construction in the Bohai Rim region is detected.
[0052] Combine below figure 1 The flowchart in the figure describes the specific implementation steps of this embodiment. Concrete steps in the present embodiment are as follows:
[0053] (1) Data acquisition and extraction
[0054] (1) Obtain the land use Shapefile format data (ArcGIS format) of the case area in 1980, 1995, 2000 and 2010;
[0055] (2) Based on the ArcGIS 10.1 software platform, extract the urban and rural construction land data (ArcGIS format) from the land use Shapefile format data of the case area in 1980, 1995, 2000 and 2010;
[0056] (3) Make grid data of...

The invention provides a detection method of town and country construction clustering. The method comprises the steps that town and country construction land space vector data, at different time points, of a research area are acquired; different dimensions of space grids are manufactured; data of the different dimensions of space grids are clipped with a boundary layer of the research area as a mask layer to obtain different dimensions of standard range grids matched with the research area; the different dimensions of standard range grids are superposed on the town and country construction land space vector data at the time points respectively so that the town and country construction land space vector data at the time points can be mapped into the different dimensions of standard range grids respectively; the town and country construction land area of each unit grid in the research area is calculated; the town and country construction clustering, space growth and regional differentiation of the research area are calculated. The method can be used for directing town and country construction plans and providing the basis for selecting the construction sites of highways, railways and other infrastructures.
Description
technical field [0001] The invention relates to the field of data processing, in particular to a detection method for obtaining urban and rural construction agglomeration and a method for generating a corresponding urban and rural construction agglomeration map. Background technique [0002] Over the past 30 years of reform and opening up, China is advancing industrialization and urbanization at an unprecedented speed. The rapid development of industrialization and urbanization drives the rapid transformation of regional urban-rural relations, industrial-farmer relations, and industrial structure, employment structure, and consumption structure. The 18th National Congress of the Communist Party of China put forward the "new urbanization" strategy, which put forward clear requirements for accelerating the construction of a new pattern of integrated urban and rural development. Therefore, scientific issues such as the transformation process, pattern, mode, and approach of urb...
