区域环境污染负荷分析的干预——效应法

Intervention——Effect Method in Analysis of Regional Environmental Pollution Loading

介绍了基于生命周期影响评价模型的干预———效应法,以及该法包括的环境效应类型的确定、环境干预因子的识别与归类、按当量因子法汇总、数据标准化和赋权评估5个技术步骤,并以广州市2003年监测数据为基础,对广州市酸化、富营养化和光化学臭氧合成效应作了研究。结果表明,广州市2003年排放的酸化污染负荷量约为379.5×103t SO2当量,主要污染物是SO2的排放(占57.4%);富营养化污染负荷量为657.7×103tNO3-当量,其中最大排放源来自人类生活(占38.4%);光化学臭氧合成污染负荷量为46.4×103t C2H4当量,主要来自于公路交通运输(占69.8%)。赋权评估表明广州市区域性的环境效应主要为光化学臭氧合成,其环境负荷为32.358×103人当量,其次为富营养化和酸化效应,环境负荷分别为8.138×103人当量和7.915×103人当量。

The intervention-effect method based on life cycle impact assessment model was introduced, including the determination of environmental effect, identification and classification of environmental intervention factor, data collection according to normal factor method, data standardization and weight right assessment in this method. Based on the monitoring data of Guangzhou in 2003, it studied the acid pollution, eutrophication and photochemical ozone synthetic pollution. In 2003, the loading of acid pollution was 379.5 × 10^3 t SO2 normal, the main pollutant was SO2（57.4% ）; the loading of photochemical ozone synthetic pollution was 46.4 × 10^3 t C2H4 normal, the main pollutant was traffic communication （69.8%）.
