【摘要】：大气污染物浓度与污染源和气象条件密切相关。海南岛大气环境不仅受到大尺度天气型影响,同时也受到由于海陆面受热不均匀所产生的海陆风的影响。通过研究热带中尺度海岛地区大气环境质量的变化特征,诊断分析大气环境污染过程形成原因和机理;基于热带海岛污染气象特征识别大气污染敏感源区域,确定源区域与典型城市的敏感系数,建立多源多污染物优化控制模型,优化主导产业布局,将产业发展的环境影响降低到最低程度,同时具有最佳经济环境效益。研究结果对于海南省在发展国际旅游岛的背景下,经济的合理快速发展具有极其重要的现实意义。采用天气分析原理和方法,分析海南岛主要热带天气系统与大气环境污染过程的分布特征和相互关系。研究结果表明,影响海南岛大气环境质量的主要天气型为大陆冷高压、热带气旋、低压槽。热带地区大型高压脊天气系统及控制下的地方性流场汇聚是造成地区大气污染物积累及峰值形成的主要原因;印缅低压槽及其偏南风、明显降水则有利于污染物的清除。根据海南岛自动气象站逐时气象资料,建立热带海岛海陆风识别标准,统计海陆风气候特征及时空分布规律。研究结果表明,海岛海陆风日从北向南海陆风日逐渐增加。海口、澄迈、临高和东方地区海风辐合发生频率较高;海岛北部内陆地区可形成明显的东北-西南走向海风汇聚带。通过敏感性研究,中尺度气象模式WRF双层嵌套模型对沿海地区海陆风有较好的模拟效果。采用CAMx-PAST数值模拟源解析方法,研究海南省各个区域分电力源、工业源、交通源、居民源、农业源、无组织扬尘六类污染源单位排放量对海南省海口市、琼海市、三亚市、东方市和五指山市5个典型城市环境空气质量的影响,研究筛选单位污染物排放量(1万吨)对区域平均浓度贡献大的敏感源区域。海南省污染源区域敏感性排序从高往低为海口地区、东部地区、西北地区、中部地区、南部地区和西南地区。基于海南省各功能区现状与区域敏感源筛选结果,提出对目前工业功能区划的调整方案。同时也对周边区域大气污染源对海南环境空气质量影响进行研究,周边区域大气污染源在旱季(1月份)海南省细颗粒物贡献率在50%左右,雨季(7月份)贡献率为30%左右。根据循环经济原理、主导产业理论和产业布局理论筛选主导产业评价指标体系,建立分级评价标准,构建循环经济型主导产业分级评价模型;筛选出3个主导产业和4个备选主导产业。根据敏感源识别结果,基于CAMx-PAST敏感系数,建立海南省6个典型区域4类源的多污染物协同控制最大允许排放量优化模型。根据SO2、NOX和VOCs单位排放量与PM2.5一次排放物之间的当量关系,确定到2020年时,海南省PM2.5浓度维持2015年水平以及在2015年基础上再降10%两种情况下,计算各类源以及主导产业SO2、NOX、VOCs和PM2.5最大允许排放量。结合天气系统演变规律及海陆风对大气污染物扩散的分析,根据源解析结果和区域最大允许排放量,调整主导产业布局,以预防区域大气环境污染。石油加工、炼焦及核燃料加工业,黑色金属冶炼及压延加工业,黑色金属矿采选业,石油与天然气开采业,非金属矿采选业均可在原地继续发展,而医药制造业应向西南地区逐步迁移,农副产业加工业应改变现有发展方式,扩大规模,可考虑在西南地区发展较大规模的农副产品加工基地。
[Abstract]:The concentration of air pollutants is closely related to the source of pollution and the weather conditions. The atmospheric environment in Hainan Island is not only affected by the large scale weather type, but also influenced by the sea land wind caused by the uneven heat of the sea and land. The atmospheric environmental pollution is diagnosed and analyzed by the study of the change characteristics of the atmospheric environmental quality in the tropical mesoscale island area. The cause and mechanism of the process are formed. Based on the meteorological characteristics of the tropical island, the sensitive source area of the air pollution is identified, the sensitivity coefficient of the source area and the typical city is determined, the multi source and multi pollutant optimization control model is established, the leading industry layout is optimized, the environmental impact of the industrial development is reduced to the lowest level, and the best economic environment effect is also given. The results are of great practical significance for the rational and rapid economic development of Hainan Province in the context of the development of the international tourism island. The principle and method of weather analysis are used to analyze the distribution characteristics and phase relations of the main tropical weather systems in Hainan Island and the atmospheric environmental pollution process. The results show that the influence of Hainan Island is large. The main weather patterns of gas environment quality are continental cold pressure, tropical cyclone and low pressure trough. The large pressure ridge weather system in the tropical area and the local flow convergence under control are the main reasons for the accumulation of air pollutants and the formation of peak value in the region; the Indo Burmese low pressure trough and its southerly wind are favorable for the removal of pollutants. The meteorological data of Hainan Island automatic weather station set up the standard of the identification of the tropical island sea and land wind, and the climatic characteristics and the temporal and spatial distribution of the sea land wind. The results show that the sea and land wind days are increasing gradually from the north to the South China Sea. The sea wind convergence rate of Haikou, Chengmai, Lin Gao and the East is higher; the inland area of the northern island is available. Through the sensitivity study, the mesoscale meteorological model WRF double layer nesting model has a better simulation effect on the sea and land wind in the coastal areas. The CAMx-PAST numerical simulation source analysis method is used to study the power sources, industrial sources, traffic sources, resident sources, agricultural sources and unorganized uplift of various regions in Hainan Province. The effect of six types of pollution sources on the environmental air quality of 5 typical cities in Haikou, Qionghai, Sanya, Dongfang and Five Fingers Group city in Hainan Province, the sensitivity of the pollutant emission (10 thousand tons) to the regional average concentration is studied. The sensitivity of the pollution source region of Hainan province is from high to low to Haikou. The region, the eastern region, the northwest region, the central region, the southern region and the southwest region. Based on the status of the functional areas in Hainan and the screening results of regional sensitive sources, the adjustment scheme for the current industrial functional zoning is proposed. At the same time, the influence of the ambient air pollution sources on the environmental air quality in Hainan is also studied, and the ambient air pollution sources in the surrounding region are also studied. In the dry season (January), the contribution rate of fine particles in Hainan province is about 50%, and the contribution rate of the rainy season (July) is about 30%. According to the principle of the circular economy, the leading industry theory and the industrial layout theory are used to screen the leading industry evaluation index system, the classification evaluation standard is set up, and the classification evaluation model of the leading industry of the circular economy type is constructed, and 3 leading products are selected. Industry and 4 alternative leading industries. Based on the sensitive source identification results, based on the CAMx-PAST sensitivity coefficient, the maximum allowable emission optimization model for multi pollutant co control of 4 types of sources in 6 typical regions of Hainan province was established. According to the equivalent relationship between SO2, NOX and VOCs unit emissions and PM2.5 emissions, it was determined to be in 2020, PM2.5 The maximum allowable emissions of various sources and leading industries SO2, NOX, VOCs and PM2.5 are calculated under the condition of maintaining the concentration of the 2015 and the second reduction on the basis of 2015. Combined with the evolution of the weather system and the analysis of the diffusion of air pollutants by sea breeze, the leading industrial cloth is adjusted according to the result of source analysis and the maximum allowable discharge of the region. In order to prevent regional atmospheric pollution, oil processing, coking and nuclear fuel processing industry, black metal smelting and calendering and processing industry, black metal mining, oil and natural gas mining, non metal mining industry can continue to develop in situ, and the pharmaceutical industry should move to the southwest region gradually and the agricultural and sub industry processing industry should be changed. The existing development mode and scale can be considered for the development of large scale agricultural and sideline products processing bases in Southwest China.
