Urban solid waste space-time management and control efficiency evaluation method based on data mining driving

Abstract

The invention discloses an urban solid waste space-time management and control efficiency evaluation method based on data mining driving. The method comprises the following steps: S1, obtaining management data of solid wastes; s2, cleaning and preprocessing the management data of the solid wastes, screening efficiency labels, and calculating an evaluation index value; s3, constructing a TOPSIS scoring model, and determining the comprehensive score of the evaluation index in each time-space state; and S4, drawing a dynamic thermodynamic diagram, performing visual display, and completing urban solid waste space-time management and control efficiency evaluation. According to the method, label information lacking in big data is mined and supplemented from network big data by using a web crawler technology, so that data sources are enriched, data granularity is refined, and data support is provided for space-time coupling and multi-benefit measurement and calculation of urban solid waste area management and control efficiency evaluation; and comprehensive evaluation is carried out on the urban solid waste space-time management and control efficiency by constructing a coupling carbon emission and environmental risk multi-benefit evaluation model.

Description

technical field [0001] The invention belongs to the technical field of solid waste evaluation, and in particular relates to a data mining-driven urban solid waste spatiotemporal management and control efficiency evaluation method. Background technique [0002] With the rapid development of urbanization and industrialization, the amount of urban solid waste is increasing, which has become one of the more serious environmental problems at present, and it is more and more important to properly handle urban solid waste. According to data from the National Bureau of Statistics, in 2020, my country will generate 1.38 billion tons of general industrial solid waste, 44.989 million tons of industrial hazardous waste, 843,000 tons of medical waste, and 235.602 million tons of municipal solid waste. Among the treatment methods of urban solid waste, sanitary landfill is the most widely used in my country, and accounts for the highest proportion of collection and transportation. In the ...

AI Technical Summary

Problems solved by technology

The above evaluation methods have the following deficiencies: ① The spatio-temporal changes of urban solid waste are ignored, and there is a lack of systematic evaluation of the effectiveness of urban solid waste management and control in two dimensions: time and space; ② Only the amount of solid waste generated, treated, and Storage capacity and other indicators of its own quantity flow, ignoring secondary environmental factors such as carbon emissions and environmental risks
