2016-2021年乌鲁木齐市生态环境质量动态变化分析

Analysis of the dynamic changes in ecological and environmental quality in Urumqi city from 2016 to 2021

本文基于生态环境状况指数评价方法体系,对2016―2021年乌鲁木齐市生态环境动态变化状况进行综合评价。计算结果表明:2016―2021年间,乌鲁木齐市生态环境质量在基本保持稳定的基础上呈现波动式向好发展的趋势,且2021年是6年以来最好的一年;风力侵蚀最高强度的逐渐减弱,以及废气污染物SO_(2)、NO_(x)排放量的大幅下降,是生态环境质量持续变好的有力支撑。

This article is based on the evaluation method system of the ecological environment status index,and comprehensively evaluates the dynamic changes in the ecological environment of Urumqi city from 2016 to 2021.The calculation results show that during the period of 2016-2021,the ecological environment quality of Urumqi city has shown a trend of fluctuating development on the basis of basically maintaining stability,and 2021 is the best year in the past six years;the gradual weakening of the highest wind erosion intensity,as well as the significant reduction in emissions of waste gas pollutants such as SO_(2) and NO_(x),are powerful supports for the continuous improvement of ecological environment quality.
