【摘要】 特殊的地形结构、气候条件和采暖方式构成,使乌鲁木齐市大气污染问题并没有得到根本性的解决。乌鲁木齐市大气污染严重的最主要原因是采暖期城市采暖燃烧排放的大气污染物的扩散,而要若要从此角度解决乌鲁木齐市大气污染问题,必须掌握由于采暖而造成的污染特征。目前,乌鲁木齐市环保局还没有专门针对采暖期集中供热的污染监控点方案。本文试图对乌鲁木齐市核心区采暖期集中供热污染监控方案进行优化研究。本文的研究方法是以《乌鲁木齐市(2002-2020年)供热规划汇编资料》及其底图、中国气象科学数据共享网中关于乌鲁木齐市的气象标准数据为基础,利用环评软件EIAA2.6对乌鲁木齐市集中供热典型污染物分布浓度进行了模拟计算、绘制污染等值线图,从而得到乌鲁木齐市核心区采暖期燃烧排放的大气污染物扩散模式,并根据计算得到的典型污染物浓度,采用模糊矩阵最大元法、Fisher最优分割法,对污染监控点进行优化研究,最终得到乌鲁木齐市采暖期集中供热典型污染物污染监控点优化方案。本文的主要研究成果是首次针对乌鲁木齐市大气污染特点,提出了建立乌鲁木齐市核心区污染监控点的理念,并提出了乌鲁木齐市核心区采暖期集中供热典型污染物的污染监控优化方案。更多还原

【Abstract】 Owing to the special landscape structure、climate condition and the constitution of heating, Urumqi’s atmosphere polution still haven’t been figured out ultimately. One of the most important elements which affecting Urumqi’s atmosphere polution is heating mode and its situation of polution discharge.Therefore if we want to solve the problem of Urumqi’s atmosphere polution,the feature of polution caused by heating must been mastered. At present,there isn’t any professional scheme towards polutant monitoring sites in central heating period, so this graduation paper focus on solve this problem.The research method of this paper is based on the《The Compilation of Urumqi’s heating plan of the year 2002 to 2020》and its background map、Urumqi’s standard climate data in China Meteorological Data Sharing Service System .By using EIAA2.6 software, simulated the typical pollutant’s concentration of Urumqi in the central heating period.Then according to the Accounted result, draw the pollltant contour map and get the mode of atmosphere pollutant discharge in Urumqi’s core area in th ecentral heating period. According to the accounted data,use Fuzzy array max-element、Fisher optimized separating method ) examine the optimized results and finally find out the optimized plan of typical pollutant monitoring sites in haeting period.This is the first reaearch which tables the proposal of setting polution monitoring sites in the central area of Urumqiaccording to the feature of Urumqi’s atmosphere pollution and gives suggestion to polution monitoring sites optimization plan of typical pollutant (sulfur dioxide and smoke) in central heating period in the core area of Urumqi.更多还原
