750 set the estimation of regression. ^ The emissions in 2000 is based on the results of China energy con sumption estimation in 2000 and the real changing tendency in 1980s. According to this, we have the data of the emissions, because the data are only a linear regression equation estimation of S02, TSP and Dust, the estimation of NOx is quoted from 'Chinese Environment in 2000' (G.P.QU, et a 1,1987). The above comparison form of possible emissions in 2000 which is the calculation for the tendency of emissions per energy consumption coefficient in 1980s and the emissions from the book of 'China Environment in 2000' (G.P.QU, et al, 1987). These data close to the value of the middle-level control project from this book. In fact, the investment on harness waste gas and the situation of real harness can't reach the level of the middle control project. 4.3. The Predicting Result By Linear Regression Method According to the data of air monitoring, to have an linear regression analysis the averange in the whole country and the corresponding emissions, we can carry out the regression coefficient of S02, TSP and Dust. During the calculation we cancel the data which may has some error. Hie data of S02 is selected from information in 1981-1987; TSP cancels the date of 1984 and Dust date is selected from 1981-1988. Now we have a regression equation • Y (S02) mg /m3 = 0.0001 * X (10.000T) - 0.0152 Y (TSP) mg /m3 = 0.00018 * X (10.000T) + 0.137 Y (Dust) T/km2 per month = 0.0l*XU0,000T)+2.847 Each the correlation coefficient of regression equation is over 0.7. Using these equation to calculate the annual average concentration of air pollutants in the whole country in 2000, we can see Table.4. In these equation, C is the concentration: K is a coefficient of correction: Q is a rate of the emissions (mg/s): (1 is wind speed (m/s): D is the mixing heigh (m): V is a width of the city which is perpendicular to the upwind of the city. The Y is the accumulation of the U*D*W from every city in whole country. We select the comparison years is 1981 and 1982. Their NOx emissions are 4.4 million tons and 4.14 millions tons. Thus we have: C mg /m3 = Q(mg/s) /2061137000 - 0.0187 Table.5 The results of NOx in 2000 comparing with in 1981 and in 1982.

EMISS: emission. 4.4. Conclusion Through the above calculation we can see that it will not have groat improvement in the air environmental quality in the year 2000,and the S02, NOx pollution will aggravate. It is estimated that the pollution concentration will be doubled.At that time, the NOx pollution will appear clearly,and the dusty pollution will keep the level of that in the end of 1980s. It must be pointed out that this con clusion should be according to an essential premise that we must have great progresses of industy harness in 1990s. 1)-We have problems from funds to technology on dealing with the S02 pollution. It seems we can't avoid that pollution which will get more serious. This has a bad influnce on southern acid rain . The estimation of NOx level accorded to the proportion modle ( X.L.LIU, and S.X.HONG, 1987 ) in each city: Cx = (Qx / ll*D*W) + K K = Co - (Qo / U*D*W) In the whole country , we have a equation : C = Q / Y + K Table.4 The results of polluted level predicting by emissions in 2000.

In 1990s, if we won't pay more attention to harness it, the auto pollution will be obviously in many cities. At present, it has drawn the attention of the department. In many cities have already launched the work for monitoring and dealing with the pollution of auto exhaustion in the last years of 1980s. It will has a good affect on restrain ing the NOx pollution.
