【摘要】：長期以來,我國一直實行污染物排放總量控制政策,按照統(tǒng)一的原則制定地方排放削減指標、分配污染物排放額度,沒有充分考慮不同地區(qū)生態(tài)環(huán)境特征、經濟發(fā)展水平、能源結構和產業(yè)結構等方面的差異,結果城市大氣污染物排放總量得到了控制,城市空氣質量卻未得到明顯的改善。區(qū)域空氣質量受空氣流動及污染源分布影響較大,為了在開展規(guī)劃過程中充分掌握區(qū)域大氣特征,既要了解污染源排放特征對空氣質量影響的差異性,也要考慮產業(yè)空間分布對城市大氣環(huán)境質量造成的影響。本文以大氣環(huán)境分級管控技術為框架,通過氣象模型模擬區(qū)域內特征氣象環(huán)境,再設置不同特征污染物的虛擬排放源進行模擬計算:通過歸納污染排放源相對濃度貢獻度評價出敏感區(qū)域分布,通過歸納污染物濃度分布情況評價出脆弱區(qū)域分布,兩者綜合后設置出污染物增量嚴控區(qū),并通過代表性的污染物監(jiān)測數(shù)據作為評價指標,找出特征污染物當前濃度分布情況,在濃度高值區(qū)設置出污染物存量減排區(qū),從規(guī)劃層面減少污染存量,控制污染物增量,再結合現(xiàn)有的環(huán)境空氣質量功能一類區(qū),構建出廣州大氣環(huán)境空間管控規(guī)劃格局。本文從三方面入手對廣州大氣空間管控規(guī)劃進行了分析設計�？臻g分級管控方面,展示了廣州市大氣環(huán)境管控區(qū)評價結果,將管控區(qū)分為環(huán)境空氣質量功能區(qū)一類區(qū)(生態(tài)保護紅線外)、大氣污染物存量重點減排區(qū)和大氣污染物增量嚴控區(qū),針對不同分區(qū)提出了管控要求。污染物防治管控方面,針對污染物、污染源的現(xiàn)狀,從“減存控增”的角度對能源、工業(yè)源、機動車流動源、農業(yè)面源等排污源管控工作提出了規(guī)劃改善建議。區(qū)域防治方面,圍繞周邊城市污染傳輸問題,從產業(yè)疏導、外來車輛、排污權交易、應急預警四個方向提出了區(qū)域聯(lián)動發(fā)展的建議。
[Abstract]:For a long time, our country has been implementing the policy of total pollutant emission control, making local emission reduction targets according to the unified principle, allocating pollutant discharge quotas, not fully considering the ecological environment characteristics of different regions, and the level of economic development. The differences in energy structure and industrial structure have resulted in the total emission of urban air pollutants being controlled, but the urban air quality has not been improved obviously. The regional air quality is greatly affected by air flow and the distribution of pollution sources. In order to fully grasp the regional air characteristics in the process of planning, it is necessary to understand the difference between the emission characteristics of pollution sources and air quality. The effects of industrial spatial distribution on urban atmospheric environmental quality should also be considered. In this paper, based on the hierarchical control technology of atmospheric environment, the meteorological model is used to simulate the characteristic meteorological environment in the region. Then the virtual emission sources with different characteristic pollutants were set up to simulate and calculate: the distribution of sensitive region was evaluated by inducting the contribution of relative concentration of pollutant emission source, and the distribution of fragile region was evaluated by inducting the distribution of pollutant concentration. The pollutant increment strict control area is set up after the combination of the two methods, and through the representative pollutant monitoring data as the evaluation index, the current distribution of characteristic pollutant concentration is found out, and the pollutant stock emission reduction area is set up in the high concentration area. From the aspect of planning, reducing pollution stock, controlling pollutant increment and combining with the existing environmental air quality function area, the planning pattern of Guangzhou atmospheric environment spatial management and control is constructed. This paper analyzes and designs the planning of Guangzhou atmospheric space management and control from three aspects. In terms of spatial hierarchical management and control, the results of the assessment of Guangzhou's atmospheric environment control area are displayed. The control and control is divided into environmental air quality function area (outside the red line of ecological protection, the key emission reduction area of atmospheric pollutant stock and the strict control area of atmospheric pollutant increment), and the control requirements for different zones are put forward. In the aspect of pollution control and control, aiming at the present situation of pollutants and pollution sources, the paper puts forward some suggestions for planning and improving the control of pollution sources such as energy, industrial sources, motor vehicle flow sources, agricultural non-point sources and so on from the point of view of "reducing storage and controlling increasing". In the area of regional prevention and control, the suggestions of regional linkage development are put forward from the following four directions: industrial diversion, foreign vehicles, emission trading and emergency warning.
