green,symbolizing life,agriculture,environmental protection.The figure is positive circle,meaning protection.,summarize,4,1.Pollution status,According to the Bulletin of Chinas Environmental conditions,air quality in cities in China was still in a relatively heavy level of pollution in 1997,while cities in the north were heavier than those in the south(see figure 3-1).The annual average concentration of sulfur dioxide is in the range of 3 248 g/m (-3),and the national annual average is 66 g/m (-3).More than half of the cities in the north and the top 1/3 cities in the south have an annual average of more than 60 micrograms per meter.The annual average of north city is 72 g/m (-3)and that of southern city is 60 g/m (3).The pollution of sulfur dioxide in cities of southwest high sulfur coal region represented by Yibin,Guiyang and Chongqing,and the cities of Shanxi,Shandong,Hebei,Liaoning,Inner Mongolia,Henan and Shaanxi provinces with large energy consumption in the north are more serious.,1.Pollution status,2.Pollution source,Energy use.With the rapid growth of our economy and the improvement of peoples living standard,the energy demand is rising.The emission of sulfur dioxide in China is increasing rapidly.This is the main cause of the longest and most harmful acid rain pollution in southwest China.Motor vehicle exhaust In recent years,the number of motor vehicles in major cities of China has increased by a large margin,and vehicle exhaust gas has become an important source of urban air pollution.In addition,automobile emissions of lead are also important pollutants in the urban atmosphere.,5,2.Water pollution,According to the State of the Environment Bulletin of China and the report of the Ministry of Water Resources,in 1997,the seven major water systems,lakes,reservoirs,and parts of Chinas groundwater were polluted to varying degrees,and the proportion of river pollution was higher than that of 1996.In the dry season,the length of polluted rivers increased by 6.3 percentage points,and the periods of high water supply increased by 5.5 percentage points.Of the more than 50,000 km of rivers assessed,42 were polluted,of which 12.2 were seriously polluted,The Yellow River is under the double pressure of pollution and disconnection.66.7%of the rivers monitored were of class water quality.The main pollution indexes are ammonia nitrogen,volatile phenol,permanganate index and biochemical oxygen demand.,6,3.noxious,waste pollution,替换文字内容,In 1997,the output of industrial solid waste in China was 1.06 billion tons,of which 400 million tons were produced by township enterprises,accounting for 37.7 million tons of total production,and 10.77 million tons of hazardous waste,accounting for 16.9 million tons of industrial solid waste discharge in 1.0.1996.The amount of hazardous waste is 1.3%.The accumulative storage of industrial solid waste has reached 6.5 billion tons,covering an area of 51680 hectares,of which about 5 are hazardous wastes.About 1.4 billion tons of municipal solid waste is produced,and two-third of the countrys cities are trapped in garbage.In recent years,the amount of plastic packaging has increased rapidly,and the problem of white pollution is prominent.,Industrial solid waste Urban domestic waste.,pollution status,Pollution source,7,大家应该也有点累了，稍作休息,大家有疑问的，可以询问和交流,8,noise pollution,9,pollution status,According to the China Environmental Status Bulletin,the noise of most cities in China was in the middle level of pollution in 1997.Among them,the impact of noise on living noise was large and expanded.Traffic noise has the strongest impact on the environment.,The equivalent sound level of road traffic noise in China is between 67.3 and 77.8 decibels,and the national average is 71 decibels(length weighted).Of the 49 urban roads monitored,those with sound levels above 70 decibels accounted for 54.9 of the total length of the monitoring.,The equivalent sound level of environmental noise in urban area is between 53.5 decibels and 65.8 decibels,and the national average is 56.5 decibels(area weighted).Among the 43 cities,33 have sound levels over 55 decibels,among which,the equivalent sound levels in Datong,Kaifeng and Lanzhou are over 60 decibels,and the pollution is heavy.,10,Environmental protection is the conscious protection and rational use of natural resources by human beings in order to prevent the natural environment from being polluted and destroyed,and the integrated management of the polluted and damaged environment in order to create a suitable environment for human life,The working environment Environmental protection refers to a variety of actions taken by human beings to solve real or potential environmental problems,to coordinate the relationship between human beings and the environment,and to ensure the sustainable development of economic society.Its methods and means include engineering,administration,law,economy,propaganda and education.,3.,11,Storage of green capital,12,4.,01,03,04,02,In order to live in peace,people will store grain and save money;enterprises will store funds and resources in order to carry out production smoothly;in order to maintain ecological security,human beings must store green capital.Because green is not only the symbol of life and health,but also the symbol of civilization and environmental protection.If there is no green,it will threaten the survival and development of human beings,the earth will face extinction.Therefore,co-existence of green capital has become the consensus and responsibility of countries in the world to deal with ecological crisis.,Storage of green capital begins with education and practice,focusing on planning and governance.,。,However,the storage of green capital cannot be done well on the basis of a gust of wind and a few slogans of Arbor Day.China is still a country short of forests and fragile ecology,and the work of storing green capital still has a long way to go.,Storage of green capital,mainly in the heritage of culture,far from the creation of brands.,13,
