【摘要】：依据物料衡算法和排放因子法等传统的基于具体生产过程的大气污染清单估算方法,根据不同土地利用类型区内主导产业活动特点选择构建相应的估算模型,应用地理信息系统(GIS)技术,实现了市县级尺度下的主导土地利用大气污染物排放空间估算,并以连云港为例,开展了研究区2010年度SO_2及PM_(10)排放实证研究.结果表明:1)连云港地区SO_2主要污染来源为重点工业企业用地、城镇用地、公路交通用地;PM_(10)主要污染来源中,耕地因秸秆焚烧导致的贡献最大,占全部总排放的43.68%,成为PM_(10)排放的关键污染来源;2)从测算空间分布结果来看,连云港中东部城区以及下辖各县城、乡镇地区是SO_2及PM_(10)的主要排放区域;3)由于本方法中污染源基于土地利用类型划分,测算过程采用数据基础的精度相对较低,故测算结果精度也相对较低,但具有相对快速简便以及成本较低的优势.
[Abstract]:According to the traditional air pollution inventory estimation method based on specific production process, according to the material balance algorithm and emission factor method, according to the characteristics of leading industries in different land use types, the corresponding estimation model is constructed. The spatial estimation of the emission of dominant land use air pollutants at the city and county level is realized by using GIS technology. Taking Lianyungang as an example, an empirical study on the emission of SO2 and PM10 in the study area in 2010 has been carried out. The results show that the main pollution source of SO2 in Lianyungang area is the key industrial enterprise land, the urban land, and the road traffic land. Among the main pollution sources, the contribution of cultivated land caused by straw burning is the greatest. Accounting for 43.68% of the total discharge, the key pollution source for the discharge of PMMA-10) from the results of calculating the spatial distribution, the central and eastern part of Lianyungang and the counties under its jurisdiction, Town and township areas are the main emitters of so _ 2 and PMSP _ (10). Because of the classification of pollution sources based on land use type in this method, the accuracy of the data basis used in the calculation process is relatively low, so the accuracy of the calculation results is also relatively low. But it has the advantage of relatively fast and simple and low cost.
