AIR QUALITY AND EMVIRONMENTAL MONITORING IN CHINA BY THE YEAR OF 2000 Chunming Cheng National Environmental Monitoring Centre, China Abstract This report is an estimation of the urban air quaiity in China by the year of 2000. It is bared on the analysis of urban air quality and its changing tendency in Chinese cities in 1980s. It analysed the predicting of condition in pollution meteorology and the planning on the exploitation of energy sources in 2000. it predicted the results with regression analysis, and compared with the situation of air pollution in American to see the influence of air- pollution in China to the world, we could see it is an onerous task for China to control and harness the air pollution. Through practices of monitoring for 17 years, China has set up an environmental monitoring network which could reflects the overall urban air quality. The effort in 1970s and 1980s, it laid a foundation for further development on air quaiity monitoring in 2000, Key Words'* Air-quality, Tendency-ana lysis, Environment-predicting 1 INTRODUCTION The human beings have been aware of the importance of 1iving environment from the bitter lessons of the environmental pollution accidents. The inter national pollution connected the people in diffe rent parts of the world together becouse of the same interests. Now, there are three main environ mental problems which demand prompt, solution 1 the increasing carbon dioxide ( (D2 1 aggravated the 'GREEN-HOUSE'; the ozonosphere was destroied and ’OZONE-HOI£' appeared in South Pole; the acid rain aggravated acidification and expanded areas. These environmental crises concern our future living environment, so people have been forced to unite to discuss the facing dangers and create the world future together, for there is only one earth in the universe so we have the common future. China is such a big country that it has one-fifth of the population in the world. Although it's a developing country, it's energy consumption and the air emissions come out at the top of the world. For example: from 1950 to 1989, the coal consumption in China has increased by 2500 % or so. The output of coal in 1989 was in excess of one billon tons. And the coal consumption were always over 70 % of the total amounts of energy consumption in 1980s. We can not completely change this situation until the year of 2000, while the ratio of coal consumption with the energy consumption will be 70 % to 75 % . Thus the long-term characteristic about air pollu tion in China which is coal smoke pollution was de termined. The rapidly increasing energy consumption intensified the air pollution, and exerted the pressure on the job of air pollution prevention. Since 1973, China has mad' a highly headway in the respect of environment protection. At the same time the environmental monitoring has rep idly developed: the specialized monitoring personnel incread from 10,000 in 1981 to over 25,000 in 1988.And more than 1800 monitoring stations in different grades have been set. up. We can get. millions of air monitoring data from these stations each year.The national air quality monitoring network was established by the end of 1980s ( M.X.Wang, et al, 1986 ), which laid a foundation in the respects about improving the quality of monitoring data and reflecting the siua- tion of air pollution timely. A study set the tasks on 'Environment Prediction Of China in The Year 2000 ' ( W.X.Wang, et al, 1987 ) which are quoted in this article many times. But becouse the materials and data on the research is limited, and it lack depth knowledge on pollution pattern, the result of prediction must be effected ( D.W.Zhau, et al, 1987 ). So, in this article mi' focus was on the analysis of the regularity of air pollution, and took the analysis on the condition of China air pollution in the main cities in 1980s as the bases, and try to calculated the predicting result in reguard of the energy source,meteorology, pollution control and other respects. 2 THE PRESENT SITUATION OF CHINA AIR QUALITY 2.1 The State of The Main Pollutants Sulfur Dioxide ( S02 ) In 1980s, the national annual average level of S02 was about 0.1 mg/m3 or so. There is only one wave, but its amplitude is within 15%, as shown in Fig.l. Fig-1 - During 1980s, tendency of S02 concentration in Chinese main cities. 744
