基于熵权TOPSIS的塑料污染评价研究

Research on Plastic Pollution Evaluation Based on Entropy Weight TOPSIS

随着塑料产品的出现,环境污染的问题逐渐引起人们的重视。因此,主要围绕塑料污染进行评价研究。首先选取合适指标构建塑料污染程度指标体系,然后建立熵权TOPSIS模型,运用标准化处理过的数据计算权重,再基于灰色关联度分析对模型进行改进,最后利用改进后的模型计算出综合得分,根据综合得分排名给出相应的塑料污染防治对策,为塑料污染研究提供理论支持和决策依据。

With the emergence of plastic products,the problem of environmental pollution has gradually attracted people’s attention.This paper conducts evaluation research on plastic pollution.First select the appropriate index to construct the index system of plastic pollution degree,then establish the entropy weight TOPSIS model,use the standardized data to calculate the weight,and then improve the model based on the gray correlation analysis,and finally use the improved model to calculate the comprehensive score,according to The comprehensive score ranking gives corresponding plastic pollution prevention and control measures,and provides theoretical support anddecision-making basis for plastic pollution research.
