乌鲁木齐市能源消耗与大气环境质量的相关性浅析

A Brief Analysis on Relationship between Energy Consumption Structure and Air Quality of Urumqi City

2002-2015年的主要能源消耗、主要大气污染物变化以及它们之间的相关性进行了分析,结果表明:乌鲁木齐市大气主要污染物废气总量、SO_2、NO_x的排放量呈上升趋势,其主要污染源来源为燃煤;废气、SO2的排放量与燃煤和燃气的消耗量呈强正相关,而NO_x排放量只与燃气消耗量呈强正相关。建议发挥乌鲁木齐市的资源优势,加大以燃气供应为主的能源结构调整,对改善当地空气质量有重要价值。

In this paper, the changes in energy consumption and air pollutants, and their correlation from 2002 to 2015 in Urumqi were analyzed. The results showed that in Urumqi city, waste gas, SO2 and NOx emissions increased by different percentages, while the main source of pollution was coal. Total production of waste gases and SOs was pos- itively correlated with the consumption of coal and natural gas, but NO~ only positively correlated with natural gas. This paper suggests that the city should make use of its resource advantages and restructure its energy supply to one that adopts natural gas as its primary energy source, which would make an important contribution to improving air quality.
