【摘要】：四川省作为我国西部省份,经济欠发达、人口稠密。人口的急剧增多、资源的大量消费,排放的污染物已经造成了环境质量的恶化,给四川省经济社会、人民的生产生活带来了严重影响。由此可以看出,我们需要建设人与自然的和谐发展,找出四川省重点的污染源、重点的污染行业,由此作为突破口,对重点污染物的行业进行排放强度的分析,以此来保护自然的生态文明理念,大力推进绿色发展、低碳发展、循环发展,促进经济社会和资源环境协调融合,真正让四川省实现其发展目标,推动人类的共同进步。本文以四川省环境统计数据为依托,通过与四川省各项污染物排放量和各行业污染物排放现状、空间分布进行层层剖析,对近年来主要污染物排放量的年度变化进行规律性分析；对大气污染物进行万元工业增加值污染物排放强度排名后,筛选出排名靠前的重点行业和重点行业的市(州)分布情况,分析筛选出的重点行业的污染物排放现状、趋势以及空间分布和污染物的贡献率,同时与运用全国第一次污染源普查系数同重点行业的污染物产生、排放强度进行比较分析,把分析后存在疑问的结果直接追溯到污染源进行逐个核查；通过对污染源的分析,并结合四川省的实际情况,找出产排污强度与系数之间存在问题的原因。通过分析发现以下几个主要环境问题：1、强化总量减排措施,减少工业源所带来的污染；2、加快工业结构升级转化,优化工业结构；4、引进先进管理模式,改进脱硫设施运行中存在的问题；5、提高重点行业氮氧化物的去除效率；6、完善环境统计制度,同时研究更适合四川省实际产排污的系数。本研究可为四川省大气污染物防治提供理论依据和决策参考。
[Abstract]:As a western province of China, Sichuan Province is underdeveloped and densely populated.The rapid increase of population, the massive consumption of resources, the emission of pollutants have caused the deterioration of environmental quality, and have brought serious impact to the economic society, people's production and life in Sichuan Province.From this we can see that we need to build a harmonious development between man and nature, to find out the key sources of pollution in Sichuan Province, the key pollution industries, and thus as a breakthrough, to analyze the emission intensity of the key pollutant industries.In order to protect the concept of natural ecological civilization, vigorously promote green development, low-carbon development, recycling development, promote the harmonious integration of economic, social and natural resources and environment, so that Sichuan Province can realize its development goal and promote the common progress of mankind.Based on the environmental statistics of Sichuan Province, this paper analyzes the spatial distribution of pollutants in Sichuan Province by analyzing the discharge of pollutants and the current situation of pollutant discharge in various industries.The regular analysis of the annual changes of the discharge of major pollutants in recent years, the ranking of the emission intensity of the ten thousand yuan industrial added value pollutants on the air pollutants,To screen out the city (state) distribution of the top key industries and key industries, analyze the status quo, trends, spatial distribution and contribution rate of pollutants in the selected key industries,At the same time, with the use of the first pollution source survey coefficient in China and the pollution generation and emission intensity in key industries, comparative analysis is carried out, and the results of the analysis are directly traced back to the sources of pollution and checked one by one; through the analysis of the sources of pollution,Combined with the actual situation in Sichuan Province, the reasons for the problems between the intensity and coefficient of sewage production are found.Through the analysis, we found that the following major environmental problems: 1: 1, strengthen the measures of total emission reduction, reduce the pollution caused by industrial sources, speed up the upgrading and transformation of industrial structure, optimize the industrial structure, and introduce advanced management models.The problems existing in the operation of desulfurization facilities are improved, the removal efficiency of nitrogen oxides in key industries is raised and the environmental statistics system is improved. At the same time, the factors more suitable for the actual production and sewage discharge in Sichuan Province are studied.This study can provide theoretical basis and decision-making reference for the prevention and control of atmospheric pollutants in Sichuan Province.
