摘要
为促进贵阳市砂石建材产业的高质量发展转型,针对目前贵阳市砂石建材产业"小、散、乱"的无序发展现状,收集了贵阳市现阶段各砂石矿石以及预拌混凝土站的生产情况,分析了贵阳市砂石建材产业以及预拌混凝土行业所存在的问题.按照国家"双碳"发展目标及行业高质量发展要求,提出构建砂石、固废"双碳"循环发展模式,按照"减量替代,以碳定产"的原则分两步实施该模式.为验证该模式对于行业碳减排的促进作用,采用排放因子法分别计算了粗放发展模式和碳循环模式的碳排放总量,测算出采用碳循环模式可有效减排二氧化碳 182.09万t,可产生约 1.275亿元的经济收益,表明该模式具备一定的实施价值,将有效促进贵阳市砂石建材产业高质量发展转型.
Abstract
In order to promote the high-quality development and transformation of the sand and stone building materials industry in Guiyang city,and in response to the current disorderly development status of the sand and stone building materials industry in Guiyang city,this article collects the production situation of various sand and stone ores and pre mixed concrete stations at the current stage,and analyzes the problems existing in the sand and stone building materials industry and pre mixed concrete industry in Guiyang city.In accordance with the national"dual carbon"development goal and the high-quality development requirements of the industry,it is proposed to build a"dual carbon"circular development model for sand and solid waste,and implement this model in two steps according to the principle of"reducing and replacing,and determining production based on carbon".To verify the promoting effect of this model on industry carbon emissions reduction,the emission factor method was used to calculate the total carbon emissions of the extensive development model and the carbon cycle model,and it was calculated that the carbon cycle model can effectively reduce carbon dioxide by 1.8209 million tons,generating approximately 127.5 million yuan in economic benefits.This indicates that this model has certain implementation value and will effectively promote the high-quality development and transformation of the sand and stone building materials industry in Guiyang city.
