Problems solved by technology

[0003] In the past, the delineation of construction land in complex mountainous areas often required leaders and designers to repeatedly visit the site and determine based on experience, which took a long time and was inefficient, subjectivity was greatly affected, and site selection errors were prone to occur, resulting in economic losses

Embodiment

[0020] Example: such as figure 1 As shown, the present invention provides a kind of technical scheme, a kind of site selection method of the mountainous area construction land based on ArcGIS, comprises the steps:

[0021] Step S1: loading the topographic map of the mountainous area into ArcGIS software, the topographic map of the mountainous area includes elevation point data and contour line data;

[0022] Step S2: In the ArcGIS software, convert the mountain topographic map into a TIN (triangular irregular network, irregular triangular network, referred to as TIN) format mountain topographic map, and then use the ArcGIS software automatic analysis function to generate an elevation analysis map; TIN is a digital The representation of the elevation model is a model organized in digital form according to a certain structure to represent the spatial distribution of the actual terrain features. ArcGIS software can set the attributes of the model and divide the elevation level. ...

Abstract

The invention discloses an ArcGIS-based site selection method of mountain area construction land. A mountain area topographic-map is used as a basis, elevation, slope and traffic area location analysis functions of the ArcGIS or same-type software are utilized, and the construction use land suitable for development is further quickly screened out through superimposing value assignment. According to the method provided by the invention, site selection of the mountain area construction land is finally determined through using software for analysis and screening on data on the mountain area topographic-map; and compared with a previous method that a technician manually carries out on-site surveys and manually selects the construction land, the method of the invention avoids selection mistakeswhich are liable to be caused by manual subjective selection, does not require a large amount of on-site survey work, and saves manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of urban planning, in particular to an ArcGIS-based site selection method for construction land in mountainous areas. Background technique [0002] With the process of urbanization and the development of social economy in our country, the demand for construction land in various regions is increasing, and the protection of basic farmland is a long-term basic national policy of our country. Therefore, more and more cities begin to look for construction land in mountainous areas. land. However, due to reasons such as slope and elevation, the land in mountainous areas can only be used after engineering transformation. How to effectively balance the cost of leveling projects and the benefits of land development has become the first factor that needs to be considered when demarcating the scope of construction land in mountainous areas, sometimes including ecological environment protection. and other related refer...
