Problems solved by technology

[0003] However, the gap in demand for urban construction land is mostly met through continuous erosion of farmland, resulting in a sharp decrease in the amount of farmland resources, which poses a huge threat to national economic construction, food security, and ecological environment protection. Existing methods of delineation usually lead to the phenomenon of crossing the boundary in the process of urban development

Embodiment 1

[0021] refer to figure 1 , a shrinking urban development boundary delineation method, including the following steps:

[0022] S1: Determine the shrinking city area that needs to be demarcated, and measure the land area and river area respectively;

[0023] S2: The total urban population and the total rural population are counted separately through the equipment;

[0024] S3: Rationally delineate rural areas and urban areas according to the statistical population data results;

[0025] S4: Measure the suitability of the land and analyze the expansion direction of the city;

[0026] S5: Delineate the river area, ecological protection area and residential area according to the survey results;

[0027] S6: Plan the boundary of the city according to the result of demarcation.

[0028] Among them, when delineating the residential area, the construction route of the road is delineated at the same time.

[0029] Among them, the ecological protection area is located on the periphe...

Embodiment 2

[0033] refer to figure 2 , a shrinking urban development boundary delineation method, compared with embodiment 1, this embodiment mainly divides the urban planning into allowed construction area, restricted construction area, prohibited construction area and reserved area.

[0034] Working principle: Determine the shrinking city area that needs to be demarcated, measure the land area and river area respectively, use the equipment to count the total urban population and the total rural population, and calculate the rural area and rural area according to the statistical population data Reasonably delineate the urban area, measure the suitability of the land and analyze the expansion direction of the city, delineate the river area, ecological protection area and residential area according to the survey results, and delineate the urban The boundary is planned. When delineating the residential area, the road construction route is delineated at the same time. The ecological protect...

Abstract

The invention belongs to the field of urban planning, and particularly relates to a contracted city development boundary demarcation method. The method includes: determining the area of a contracted city to be demarcated; respectively measuring the land area and the river area; counting the total urban population and the total rural population through equipment; reasonably demarcating the rural area and the urban area according to the statistical population data result; measuring the suitability of land, analyzing the expansion direction of a city, demarcating a river region, an ecological protection region and a living region according to a survey result, planning the boundary of the city according to a delimiting result, and demarcating a construction route of a road while demarcating the living region. According to the invention, through demarcation of the construction allowing area, the construction limiting area, the construction forbidding area and the reserved area, urban land can be reasonably planned and utilized, and the boundary crossing phenomenon is avoided.

Description

technical field [0001] The invention relates to the field of urban planning, in particular to a method for demarcating the development boundaries of shrinking cities. Background technique [0002] In the process of rapid urban development, problems such as accelerated spatial sprawl, traffic congestion, environmental pollution and ecological damage, and social isolation have become increasingly serious. How to scientifically and effectively curb the evolution of these adverse trends has become the focus of common attention of the government and academia. A complex giant system is affected by many factors, and the spatial conflicts in the interaction of various elements within the urban system are obvious, and the demand for construction land in the process of urban development continues to increase. [0003] However, the gap in demand for urban construction land is mostly met through continuous erosion of farmland, resulting in a sharp decrease in the amount of farmland reso...
