中文摘要:
      随着我国城市化的迅速发展,大气污染问题成为影响人们生活幸福感的重要因素之一。施工、裸露地面等引起的扬尘成为城市大气颗粒物污染的主要来源。将GIS方法和原环保部《扬尘源颗粒物排放清单编制技术指南(试行)》推荐的计算方法相结合,估算出2016—2018年长沙市城区施工扬尘源、土壤扬尘源的颗粒物排放量,从时空分布特征与空间自相关等多个方面剖析了扬尘源的颗粒物排放情况。结果表明:长沙市扬尘源沿中心城区向西、北方向辐射,呈现出半圆环形的带状分布,以城乡接合部最为集中;2016—2018年,长沙市城区扬尘源排放量总体呈现逐年递减的变化趋势。研究结果与长沙市城区实际情况基本相符,可为长沙市扬尘污染控制策略的制定提供参考。
英文摘要:
      In the rapid growth pace of urbanization,the atmosphere pollution has become one of the important factors that influence happiness and quality of people’s lives.Dust caused by construction sites and uncovered soil has become the main source of particulate air pollution in urban areas.Based on GIS method and the emission calculation method,PM2.5 emissions from construction sites and uncover soil areas in Changsha from 2016 to 2018 were estimated.And then,the spatio-temporal distribution characteristics and autocorrelation of various types of dust sources were analyzed based on a grid model of dust sources.The results showed that dust sources spread from the central city to the west and north,showing a semicircular annular zonal distribution,the densest place was the border between urban and rural areas.Also,the emission of dust sources showed a decreasing trend from 2016 to 2018.The research results were basically consistent with the actual situation in Changsha,it could provide reference for establishing control strategies on dust pollution in Changsha.
