n the period of this sub-plan, emphasis will be laid on the particle control in the air pollution control and protection of drinking water sources in water pollution control, thus to realize a fast improvement in the environmental quality. To tackle both symptoms and causes, this process needs not only the traditional end-of-pipe measures, but also the source reduction instruments like promoting cleaner production, developing recycled economy, raising higher standard, refining city plan, adjusting energy structure, improving industrial layout, and introduction of automobiles at higher quality. In this way, the total discharge of pollutants should be reduced significantly, leading environmental pollution control to a new stage.
) Prevention and Control of Air Pollution
The air quality improvement of Beijing is a complex challenge that not only involves the urban area, but also relies on the ecological improvement in the whole city and the surrounding areas. While strengthening the initiative to reduce air pollution within the urban area, citywide and regional ecological improvement, agricultural and industrial structure adjustment, and rational utilize of limited water resources are all of critical importance.
Prevention and control of coal-burning pollution: Beijing will greatly increase the use of cleaner energy and reduce coal burning in the urban areas. In 2007, the total coal consumption in the city will be reduced to less than 15 million tons from over 26 million tons in 2001; coal burned in the urban area will be reduced from 16 million tons in 2001 to about 8 million tons with only high quality coal with low sulfur content allowed in the city. At the same time, efforts will be made to popularize the renewable energy, including solar, geothermal and wind energy.
The second natural gas transmission pipeline from the gas field to Beijing will be built to increase natural gas supply capacity to 5 billion cubic meters in 2008.
Planned power transmission and distribution projects will be completed to introduce power from the surrounding area into Beijing. Advanced technology, like heat pump will be applied along with the urban rehabilitation to provide electric heating service for about 20 million square meters’ floor area in 2007.
Natural gas power generation projects in Beijing Third Co-generation Power Plant and Gaojing Power Plant will be accomplished (the coal boiler in Gaojing Power Plant will be closed to reduce coal burning by about 1.5 million tons). New and expansion projects for gas-fired heat and cool co-generation plants will be implemented at Taiyanggong, Caoqiao and other places. In addition, the potential of the existing heating facilities will be tapped. With all these measures; floor area with district heating supply will increase by another 50 million square meters by 2008.
Development of renewable energy is promoted to achieve sustainability. Geothermal resources will be exploited to expend provide heating and cooling service for around 5 million square meters floor area by 2008. Solar energy and bio-mass energy utilization will receive high attention in rural area.
