In the past year, the environmental monitoring station of Quanzhou Environmental Protection Bureau monitored the air, water quality and noise in the urban area through several monitoring points, and reached this conclusion.
Among the four indicators of urban atmospheric environmental quality, the annual average values of SO2 and NOX all meet the first-class standard of national ambient air quality standard.
Quasi. The annual average value of TSP exceeds the secondary standard of Ambient Air Quality Standard. The frequency of acid rain is 3 1.8%. Comprehensive evaluation of these four indicators, Quanzhou city
The air quality index in this area is 0.84, which is similar to 0.85 in 2004, but it belongs to a light pollution level. The frequency of acid rain is the same as that in 2003, but
The pollution level has increased slightly, and acid rain pollution is still serious.
Urban environmental noise pollution is still serious. In 2005, the average equivalent sound level of urban environmental noise was 55.8 dB, slightly lower than that in 2004.
According to the first-class functional area standard, it still exceeds the standard by 0.8 dB.
The water quality monitoring results of Jinjiang River system show that the water quality compliance rate of Jinjiang River system section is only 40%, and the water pollution is still quite serious. The main pollutants are
Petroleum, followed by chemical oxygen consumption. The effluent from two water plants in Quanzhou meets the national drinking water standard, and 100% of the samples meet the standard.
The water quality of ditches and rivers in urban areas is worse than that in 2004. Among them, the water quality of plain canal is better, and the water quality of Baguagou and Huancheng River is worse. The water quality in Quanzhou Bay is worrying,
The pollution of inorganic nitrogen and inorganic phosphorus is more and more serious, which needs to be paid attention to.
Water crisis
Jinjiang is divided into east and west tributaries from Shuangxikou in Nan 'an. Xixi, the main stream, originates from Ladiling, Dadeban, Zhou Tao Township, northwest Anxi County, with a river length of 153km and a drainage area of 310/km2. Dongxi originates from the snow-capped mountains in the north of Yongchun County, with a river length of 120km and a drainage area of 19 17km2. Shuangxikou to Hekou (Chongxunpu Community) is the main stream, with a length of 29 kilometers and a drainage area of 6 1 1 square kilometer.
Quanzhou Water Conservancy Bureau said that the situation of water resources protection in Jinjiang River Basin is worrying. There is no sewage and garbage treatment plant (field) upstream of Jinjizha. Most domestic sewage and industrial wastewater are directly discharged into Jinjiang water system without treatment. The water quality of some rivers has exceeded five kinds of water quality standards, and Shanmei Reservoir has become eutrophic. ...
According to the relevant personnel of the Water Conservancy Bureau, the main problems existing in the water resources crisis in Jinjiang River Basin are: the threat of over-exploitation of the upper mountain forests to water conservation and soil and water conservation; Non-point source pollution caused by pesticides and fertilizers in upstream tea gardens; Ecological damage caused by dehydration section of small hydropower stations in the middle and upper reaches of rivers; Enterprise wastewater and domestic sewage in all river basins, especially in the middle and lower reaches.
Today is the last day of China Water Week. Seven days ago, March 22nd was the13rd World Water Day. The theme of this year's commemoration and activities in China is "Ensuring the safety of drinking water and maintaining the safety of life". At the same time, the United Nations designated 2005-20 15 as the International Decade for Action, with the theme of "Water for Life".
Jinjiang water is the water of our life. Every day, we drink water from this river. Jinjiang is like a mother to a child to us, so we affectionately call Jinjiang the mother river. But now, "mother" has changed. Her traffic decreased, and she became thinner. Her face is cloudy because of pollution. ...
Take a look at this set of data about the change of total surface water resources in Jinjiang River Basin-
The multi-year average is 5 1 100 million cubic meters; In 2000, it was 7.337 billion cubic meters; 20015.227 billion cubic meters; 465,438+84 million cubic meters in 2002;
In 2003, it was 34170,000 cubic meters, 33.3% less than the average for many years;
In 2004, it was 287,654.38 billion cubic meters, 43.71%less than the average for many years;
In 2005 ... let's take a look again. This set of data about sewage
In 2003, the city's wastewater discharge was 247 million tons, an increase of 25 million tons compared with 2002, of which the industrial wastewater discharge was 65.438 67 billion tons, an increase of 65.438 0.06% compared with 2002. The domestic sewage discharge is 80 million tons.
We can't just sit still, because a well is drying up and the water level in the reservoir is falling. ...
We can't sit still, because there are landslides everywhere and pieces of fish and shrimp turn white. ...
We can't just sit back and wait. According to the long-term planning of Quanzhou's water consumption, by 20 10, Quanzhou will be short of water by hundreds of millions of cubic meters, which is equivalent to 1/3 of the current annual water consumption of the whole city. Based on this calculation, by 20 10, Quanzhou will have about 100 days without water.
During the seven-day "China Water Week", we went deep into some villages, reservoirs and river sections in the upper, middle and lower reaches of Jinjiang River, and investigated the changes of water resources in Jinjiang River Basin in recent years. This paper attempts to analyze the current situation and causes of water resources changes in Jinjiang, hoping that people will cherish and safeguard our mother river together and make "mother" rejuvenate. ...
Investigation background
Summary of the work of Quanzhou Soil and Water Conservation Committee in 2004, at present, the problem of soil erosion caused by mountain development in Quanzhou is outstanding-according to the survey, the soil erosion area of tea gardens in the city is 748,000 mu, accounting for 48.96% of the total area of tea gardens. Mainly concentrated in the upper reaches of Jinjiang River, the loss area of tea gardens in the upper four counties (cities) is 665,400 mu, accounting for 88.96% of the total loss area of tea gardens in the whole city and 74.38% of the total area of tea gardens in the upper four counties (cities). It seriously endangers the protection of water resources in the upper reaches of Jinjiang, and even the ecological security and sustainable development of the city.
Four counties (cities) refer to Anxi, Yongchun, Dehua and Nan 'an.
"Because most of the incoming water in the Jinjiang River Basin is in the middle and upper reaches of the mountain, the ecological environment in the upper reaches plays a crucial and decisive role in the water resources of the whole Jinjiang River Basin." According to the relevant person in charge of the office of Quanzhou Soil and Water Conservation Committee, the pollution of various factories is now point source pollution of Jinjiang water source, while some counties (cities) in the middle and upper reaches use a lot of pesticides and fertilizers in the process of planting cash crops on a large scale, resulting in non-point source pollution. "This kind of pollution has no specific direction, but the pollution of thousands of square kilometers is no less destructive to Jinjiang water resources than the factory sewage we usually say."
Anxi County is the birthplace of Jinjiang, and the large area of mountains and abundant precipitation every year have a particularly important impact on the water resources and water quality of Jinjiang River Basin.
We chose Jiandou Town, Anxi County, near Xixi in the upper reaches of Jinjiang as the investigation object.
Because the water from all the streams on the mountain here will flow into Xixi in the upper reaches of Jinjiang River. ...
It is difficult to drink water in Hou Jing village.
On March 25th, the fourth day of China Water Week, Hou Jing Village, Jiandou Town, Anxi County. The well in front of the villager Wu Zhixiang's house was half-hidden.
"Well water can't be eaten, it can only be used for washing clothes." Wu Zhixiang said that their family stopped drinking the well water in front of their house four years ago because it was "smelly, strange and astringent".
Wu Zhixiang suggested that reporters look at the bottom of the well-there is a trace of water in the dark bottom.
"The well is eight meters deep, and now there is only about one meter of bottom water." He pointed to the wall of the well. "Just a few years ago, the well water level was still relatively high."
According to Wu Zhixiang's family, this well is a lucky well among more than ten wells in the village. "Other oil wells have bottomed out." .
Wu Zhixiang opened the back door and took us to a dry well. "This well was dry when I got married, and now the child is 5 years old." He introduced that he has been working for at least six or seven years.
According to the villagers, drinking water has become a difficult and huge investment in Hou Jing village.
