Description
Technical Field
The invention relates to the field of pollution degree evaluation, in particular to a regional influence degree evaluation method and system for pollution discharge behaviors of industrial enterprises.
Background
The method mainly relates to three concepts, namely firstly, pollution equivalent, namely measuring comprehensive indexes or measurement units of environmental pollution caused by different pollutants according to the harmful degree of the pollutants or pollution emission activities to the environment and the technical economy of treatment. The pollution equivalent value is defined based on the environmental pollution factor specifying the degree of harm and toxicity to the organism and the treatment cost of the main pollutants in unit amount, compared with other pollutants in equivalent amount, usually in unit: kilogram also has the units of pause, head, feather, etc. The pollution equivalent number is the number of pollution equivalents, dimensionless, in general terms, pollution equivalent number = emission/pollution equivalent value. However, the pollution discharge of the industrial enterprise not only involves gas pollution discharge and sewage discharge, but also has possibly complex and inconsistent conditions, and the pollution discharge behavior of the industrial enterprise is difficult to be accurately evaluated only according to the data of the pollution equivalent number of the enterprise.
In the prior art, methods for evaluating pollution sources by establishing models exist, so that the accuracy of evaluating the pollution sources is improved. Chinese patent publication No. CN110111022A discloses a method and an apparatus for evaluating a water pollution source, in which the number of pollution equivalents and water source pollution data indicate negative effects caused by the water pollution source, and economic benefit data can indicate positive effects corresponding to the water pollution source, so that evaluation data of the water pollution source is determined based on the number of pollution equivalents, the economic benefit data and the water source pollution data, and the evaluation data can comprehensively and accurately evaluate the water pollution source. However, the prior art also has the following technical problems:
firstly, in the prior art, evaluation indexes are not complete enough, only economic indexes are considered, and other indexes such as humanity, resources, energy and the like are not considered, and it is emphasized that the economic, environmental, population, resources and energy conditions of various regions are not completely consistent, if only the single factor of economy is considered, the pollution evaluation is not objective enough, and the influence degree of the factors on the pollution cannot be positioned, so that comprehensive reference cannot be provided for relevant government departments in making policies. The weight of each index participating in evaluation is not given clearly, and the method cannot be popularized to other regions for use.
Secondly, it is known that industrial enterprises in different industries have different local pollution levels, for example, the textile industry is an industrial classification with large water consumption and large water discharge, and is characterized by large discharge amount but relatively low unit pollutant treatment cost. The petrochemical industry discharges more sewage in the form of non-aqueous phase liquid, and is characterized by small discharge amount and higher treatment cost of unit pollutants. The industrial systems in China are divided into 41 major categories, including coal mining and washing industries, oil and natural gas mining industries and the like, how to objectively evaluate the influence degree of the pollution discharge behaviors of industrial enterprises in a region on the region, factors of different industries need to be considered, but an evaluation model for evaluating by different industries is not mentioned in the prior art.

s3, establishing an area influence degree evaluation model corresponding to each industry classification, and determining the relation between the area influence degree and the pollution degree influence factor;
s4, determining the weight of each pollution degree influence factor in the evaluation model corresponding to each industry classification according to historical data;
and S5, calculating the influence degree of the pollution discharge behavior of the regional industrial enterprises by substituting the evaluation model corresponding to the industry classification to which the industrial enterprises belong into the assessment area according to the industry classification to which the industrial enterprises in the region to be assessed belong and the pollution degree influence factor value of the industrial enterprises.
Preferably, the industry classification in step S1 is divided into 41 major classes.

Preferably, in step S3, the influence factor of the area and the influence factor of the pollution level are in a linear relationship.
Preferably, in step S4, for each industry class, a logistic regression method is used to determine the weight of each pollution degree impact factor in the evaluation model corresponding to each industry class.
Preferably, in step S5, when there are multiple industry classifications for multiple industrial enterprises in the area to be evaluated, the method further includes the following steps:
s51, respectively calculating the influence degree of the industrial enterprise pollution discharge behaviors of each industry classification on the region;
s52, calculating the ratio of the quantity of the industrial enterprises of each industry classification to the total quantity of the industrial enterprises in the area;
and S53, weighting according to the ratio to obtain the regional influence degree of the pollution discharge behaviors of all industrial enterprises in the region.
