This request on the "requirements of the 2010 national total sulfur dioxide emissions control in 2000," the requirements of the current appears to have been unable to reach. Original formulation of the requirements of the main goal is to fall into disuse backward production capacity, completely ignoring the economic growth brings huge energy consumption increase.
Coal is the most important source of energy in China. China's coal production and consumption are the world's first, almost equivalent to the whole world

These coal with the same way basically have three, industrial, thermal power, and heating, in which the amount of thermal power and industry is significantly increased year by year:

At the same time, China's sulfur dioxide emissions are so (ET al. Lu, 2010):

From the general trend of view, after 05-06 years of sulfur dioxide emissions peak, is currently being slow down.
Purple line is called MEP, is zoned out of the red line of the Ministry of environmental protection, the current look is gorgeous Li ignored. Moreover, the current emissions of sulfur dioxide is about 1.5 times in 2000.
At the same time, the following is the frequency of acid rain occurred in acid rain area：

There was a peak in the frequency of acid rain in the acid rain area of 05-06, and there was a decreasing trend at present. Reason and national plan on ("existing coal-fired power plant sulfur dioxide governance" Eleventh Five Year "plan"), slang called "Eleventh Five desulfurization, 1025 see denitration", tidies up the sulfur-containing compounds, below pack containing nitrogen.
North is not the traditional acid rain area, the current generally accepted view is that the north of precipitation, low air humidity, low soil acidity. According to the current research results, northern China, especially in the North China Plain, is a traditional agricultural region in China, and the ammonia concentration in the air is relatively high. The results indicate that there are about 3 million 70 thousand tons of ammonia emissions in North China (ET al. Zhang, 2010). Such a high ammonia concentration will inhibit the formation of acid rain, but it will also cause other serious consequences, and the other.
At present, the northern region of acid rain appears mainly in Shanxi, Beijing, Henan,, Anhui, Shandong and other parts of the region, its frequency and sulfur dioxide emissions are closely related:

As shown in figure, the North China Plain is almost all sulfur dioxide emissions, acid rain frequency increase is understandable.
Sulfur dioxide emissions will lead to another problem, is the haze, that's another story.
