Gathering area identification and division method for rural domestic sewage treatment

Abstract

The invention provides a gathering area identification and division method for rural domestic sewage treatment, and the method mainly comprises the steps: collecting territorial geographic data, geographic space data cloud data, rural population data and remote sensing image data; adopting ArcGIS software to process territorial and geographic data to obtain matched administrative boundaries (villages, towns, districts, counties and cities) and rural residential area distribution, generating DEM data and topographic and geomorphic data through geographic space data cloud data, and then coupling the DEM data, the topographic and geomorphic data and rural population data, establishing a rural residential area-rural gathering area-environment sensitive area space corresponding relation, and verifying a result by using a remote sensing image and adopting an on-site verification mode so as to finally obtain resident gathering area distribution conditions of different rural areas. The method can scientifically and efficiently identify the spatial distribution characteristics of the rural residence area, can support rural domestic sewage treatment, and can be used for improving the quality of the rural living environment.

Description

technical field [0001] The invention belongs to the field of rural environment management, and in particular relates to a method for identifying and dividing rural settlements. Background technique [0002] In recent years, my country's rural economic level has improved significantly, but the problems caused by the uncoordinated rural economic development and environmental construction have become increasingly prominent, among which water pollution is the most serious problem. Therefore, it is imperative to carry out rural domestic sewage treatment, comprehensively improve the quality of rural water environment, improve the rural living environment, and actively explore reasonable and effective rural domestic sewage treatment models. [0003] Rural settlements refer to all settlements except cities, townships and towns, which are the settlement places for farmers to produce and live. Rural agglomeration is a rural residential model, service management model and industrial p...

Problems solved by technology

[0005] The traditional settlement area identification method is mostly determined by human investigation. This method can accurately determine the geographical location and population size of a certain settlement area, but it is time-consuming and laborious, and is greatly affected by subjective factors, which often leads to significant differences in results.

At present, many scholars use quantitative remote sensing methods to efficiently identify settlements. This method can effectively identify large-scale cities and town settlements. Quantitative remote sensing is not applicable to the identification of rural settlements to a certain extent
