Abstract


With the rapid economic development and promote the rapid urbanization , China's regional atmospheric environmental problems have become increasingly severe , prompting regional atmospheric environmental capacity assessment questions is an urgent need to address the scientific and technological issues . However, the current carrying capacity for the assessment of regional atmospheric environment not yet have a unified theoretical understanding of complex and diverse evaluation methods can not be well applied to the actual work. In this paper, on the basis of existing studies , respectively, atmospheric pollutants and human social and economic activity scale atmospheric environment carrying the object is established based on the capacity and scale of socio-economic activities based on both regional atmospheric environmental capacity assessment. Based on the capacity of regional atmospheric environmental capacity assessment methods for regional air pollution , we proposed the box model , simulation method and linear programming Combination of capacity estimation method . The basic idea is the true source of pollution and emissions of highly polymerized by location as the source unit , based on linear programming method to seek regional maximum capacity and optimal allocation scheme . Among them, the use of a small box model to ensure a regional scale pollution of the environment quality requirements , the use of simulation to consider secondary pollution area precursors environmental capacity constraints , the tank capacity and simulation model capacity constraints as the Planning Act . This method taking into account the sources of local and regional impact , a secondary impact and influence , capacity planning and layout optimization with regional characteristics . Based on the scale of socio-economic activities in the atmospheric environmental capacity assessment method, according to sources within the region \and secondary pollution impacts as constraint conditions to establish large-scale linear programming model . Among them, the application of air quality modeling pollutant emissions and environmental quality of the linear and quasi- linear response relationship . Case study results showed that the two regional atmospheric environmental capacity assessment methodology is reasonably practicable , for different needs and conditions of application.
