Management of establishment, construction and maintenance.2 Normative referencesThis standard refers to the following documents or their terms. For undated references, the latest edition applies to this standard. GB 3095-2012 Ambient Air Quality Standard HJ 633-2012 Environmental Air Quality Index (AQI) Technical Regulations (Trial)3 Terms and definitionsThe following terms and definitions apply to this standard. 3.1 Urban assessment station Monitoring points set up for the purpose of monitoring the overall status and trends of air quality in urban built-up areas, participating in urban rings Air quality assessment. The minimum number of settings is determined by the urban built-up area and population according to this standard. Each ring The assessment of urban air quality points generally ranges from 500 meters to 4 kilometers, and sometimes extends to a radius of 4 kilometers. The range of tens of kilometers (such as areas where the concentration of air pollutants is low and whose spatial variation is small). Can be referred to as the city point. 3.2 Regional air quality assessment area Monitoring points set up for the purpose of monitoring regional air quality conditions and pollutant area transmission and impact areas, And regional environmental air quality assessment. Its representative range is generally tens of kilometers in radius. Can be referred to as a regional point. 3.3 Ambient air quality background points A monitoring point set up for the purpose of monitoring the ambient air quality background level at the national or regional level. Representative van The circumference is generally more than 100 kilometers in radius. Can be referred to as the background point. 3.4 Pollution monitoring point source impact stations In order to monitor the impact of the main fixed pollution sources and industrial parks and other pollution source areas on the local ambient air quality The set monitoring points generally represent a radius of 100 to 500 meters, and can also be expanded to a radius of 500 meters to 4 kilometers (such as Consider the effect of higher point sources on ground concentration). 3.5 Roadside traffic point traffic stations Monitoring points set to monitor the impact of road traffic sources on ambient air quality, representing the daily life of people And the vicinity of the road and its vicinity affected by the discharge of road traffic pollution sources in the activity place.4 Ambient air quality monitoring point layout principle4.1 Representative It has good representativeness and can objectively reflect the ambient air quality level and variation law within a certain spatial range. Evaluate the environmental and air conditions in cities and regions, and the impact of pollution sources on ambient air quality to meet the provision of environmental air conditions to the public. The need for health guidelines. 4.2 Comparability The same type of monitoring point setting conditions are as consistent as possible, so that the data acquired by each monitoring point is comparable. 4.3 integrity Environmental air quality assessment urban points should consider the comprehensive environmental factors such as urban natural geography and meteorology, as well as industrial layout, The socio-economic characteristics such as population distribution should reflect the air quality of the main functional areas and major air pollution sources in the layout. The trend and the trend of change are rationally arranged from the whole, and the monitoring points are coordinated with each other. 4.4 Forward-looking The layout of monitoring points should be considered in conjunction with urban and rural construction planning, so that the identified monitoring points can take into account the future changes in urban and rural spatial patterns. trend. 4.5 Stability Once the location of the monitoring points is determined, it should not be changed in principle to ensure the continuity and comparability of the monitoring data.5 Ambient air quality monitoring point layout requirements5.1 Environmental Air Quality Assessment City Point 5.1.1 Located in the built-up area of each city, it is relatively evenly distributed and covers all built-up areas. 5.1.2 Estimating the concentration of pollutants in the built-up area of the city using the method of urban encrypted grid point measurement or mode simulation calculation Overall average. The arithmetic mean of the concentration of pollutants at all city points should represent the total concentration of pollutants in the built-up area of the city. Body average. 5.1.3 Urban Encryption Grid Point Measurement refers to the uniform division of urban built-up areas into several encrypted grid points.
