Abstract: The so-called "Jing-Shan-Mon borderland" energy industrial area is situated between Shanxi and Shaanxi Provinces and Inner Mongolia Autonomous Region. The middle reaches of the Yellow River are located in the region. With an total area of 54 000km2, it is one of the major energy industrial bases in China. Coal. oil, natural gas and other natural resources are distributed widely in this borderland area. Yet, owing to the misuse of these resources, the environmental pollution is quite serious recently. In this paper, air. water and waste solid pollution and its control planning are discussed. The control of the concentration of pollutants in atmosphere and in river water by 2000 and 2010 years are also discussed.Discharge of waste water in 1990 amounted to 1700?104 tons. of which 44. 8% was by electrical power industry. 17. 0% by chemical industry and 12. 7% by textile industry. The water of the Yellow River is seriously polluted. The major pollutants are suspended substances. oxygen-consuming organic matter and oils. The content of suspended substances is over 100% more than national standard, and is rising. The oil pollutant exceeds the standard by 60% - 100% and mercury is over 5. 7%.The emission of waste gases from various plants and urban areas are the main source of air pollution. The annual amout of waste gases is 132. 4?104m3. The electrical power industry has a high emission of waste gases which accounts for 34. 7% of the total, and chemical industry has 14. 4% .In residential and industrial areas. the average suspended particles are different. The concentration of total suspended particles is 0. 69 mg/m3 in residential areas 0. 947 mg/m3 in industrial areas. but only 0. 202 mg/m3 in clean areas. The quantity of industrial solid waste directly released is 370?104t, of which 75% is from coal mineral wastes. This amout reaches 17% of the total of the Country.The selection of the targets for environmental improvement is concentrated in the areas with major resources and for the main pollutants. The COD in the water and SO2 in the air are chosen as main pollutants. The treatment of industrial waste water should reach 45% - 50%, and the recycling amount of industrial used water should make up more than 50% - 50%. 70% of urban used water should be treated.In the past, the atmospheric pollution in the area was not strictly controlled. The reduction of waste gases and SO2 emission will have great effects. It is required that the concentration of SO2 in atmosphere in most parts of this area should be kept at a lavel of national third standard.
