Life of three major rivers the Yangtze River source environment
Tuotuo Coast residents have had to buy water to drink mineral water plant; the Yellow River forced high, the potential diversion is also inevitable ; Huaihe River Basin Shilianghe fishermen no longer fish the reservoir can be fishing, water bug can only change money subsistence fishing to survive.

China each year nearly 20 natural lakes, quietly disappeared, the number of such rapid disappearance of the lake stand it? Blind due to years of development, reclaiming land from lakes, watershed vegetation destruction, soil erosion, sedimentation large lake, Poyang Lake's volume has been reduced over the past 37 billion cubic meters to the current 298 billion cubic meters. The pulp of a chemical fiber plant silk plant, 7,000 tons per day of sewage corrosive, through underground pipes directly discharged into the Poyang Lake. Around the Poyang Lake area, how many large and small enterprises in the sewage to the lake, this is a mystery. Dolphin and finless porpoise, as well as endangered species like cranes, but also live in the Poyang Lake, how long? This is also a mystery.

flows into the Xiangjiang River is a river in Hunan province, is the land of plenty. Today was the Xiangjiang River pollution in industrial waste residue, see Straight row of large urban sewage Xiangjiang River. Distributed in several major cities along the Xiang River, forming the upstream discharge and downstream drinking situation. People complained; not on a clean drinking water, how are these? 3000 national key industrial pollution enterprises, accounting for 217 of Hunan, which accounts for the distribution in the Xiangjiang River more than 150, a large number of sewage discharged into the Xiangjiang River.
Dongting Lake was originally part of the ancient Yunmeng Ze. Yunmeng Chak area has reached 40,000 square kilometers. Anti summer when the water rose in Dongting Lake area when there are about 5,000 square kilometers; 1941, titled Narrow lake about a year after the liberation of 88.6 square kilometers. According to incomplete statistics, the sediment deposition in Dongting Lake in the over 59 million tons. Jianghan lake by the early 20th century the number of 1066 decreased to 80 309, with an area reduced from 8,330 km2 to 2,980 km2, the basic cut of the Jingjiang Ping to contact the original and the Yangtze River Water Resources ... ... Hunan writers see Peng Ming sad to say, Why after 80 years of the 20th century made an average of two years the Yangtze River flood? Uninterrupted for several years and sometimes even floods? That flood of 1998 had more than a thousand people were killed and direct economic losses of 160 billion yuan. The years that we really give the Yangtze desperate, it had to retaliate against us ah! Social prosperity, but the natural ecological environment is poor?
the Yangtze River in 1951 -1999 the average annual sediment discharge 500 million tons, ranking fourth in the world. Hubei abnormal curvature of the Jingjiang River Bend, a small gradient, slow water flow, coupled with fewer and fewer forests Yangtze River, soil erosion, so a lot of sediment deposition in the Jingjiang section, so that high-elevation river silt each year.

Wuhan Yangtze River Soil and Water Conservation Board were told this writer Hu A: Yellow loss ratio is 1 to 1, while the Yangtze River is a 3 to 1, erosion is greater than the loss. If, like the Yangtze River Yellow River erosion as the loss of a ton to a ton of the Yangtze River, Yangtze River has long been that even the Yellow River over the Yellow River. You can dry the North South, the South lack of soil, you are not likely to land south north transfer, right?
make matters worse, water pollution. Spent several years in 2000, Yangtze River Basin industrial and domestic waste water discharge volume of 23.39 billion tons, an increase of 2.7 billion tons worse than the standard Class Ⅲ water Pingjia river length of the total river length of 26%, 5% increase over 1999; the whole river basin downward trend in water quality, a large number of lake eutrophication, sewage volume is among the top 5 in Hubei, Jiangsu, Jiangxi, Sichuan and Shanghai. Total water intake along the Yangtze River about 500, have been polluted to varying degrees by the shore impact zone, the current of the Yangtze River industrial, urban domestic water consumption of about 600 million tons, mainly from the shore, unable to find compliance with drinking water water health standards, the many ways the city is forced to use river water to improve the quality of drinking water. If you change the water from the river, to be increased investment of several billion dollars more than the original. North is functional water shortage, the South can still talk a moment of economic emergency, can the South and a lot of water that the water quality of waste water resources, water is more terrible than functional.

press corps from Shanghai, travel up the Yangtze, half-way across 13 provinces, which lasted 108 days, travel over twenty thousand kilometers, field trips, the ecology of the Yangtze River, reaching as far as the Yangtze River source Tootoo River. All the way along the Yangtze River to drink, holding up a can directly drink water, source water should always be yourself? But local residents said Tuotuohe, you still think Tootoo less water? Just been to a few days ago here, the snow, otherwise, the river's water is even less than it is now, not just small drips or mud. We used to drink this water, in recent years not to drink it! We usually drink the water, are driving tractors to more than a dozen kilometers away, We are guarding Tuotuohe can spend money on water to eat. Tuotuohe very hard water, people drank to get sick, do not drink animal fat.
Yellow: dirty hanging in the air flowing
River Yellow River has been known as the mother river of Chinese nation, but in recent years the Yellow River soil erosion, drying, pollution and ecological deterioration shocking . Western region is an ecological deterioration of the situation how? How Yellow is a countdown to the embarrassment of life at risk? The deterioration of human ecology is an acceleration of what led to the terrible deterioration of the natural ecology extraordinary it?
Tibetan Plateau is the Water Tower and pasture because of overgrazing and rodent head as bare as Laizi Ban bald abound. Pasture often had a chance to grow up, he was hungry and herds hastily Kenshi out. Local cadres said: This ranch is very miles better! Maduo more than a decade ago only 30 acres of pasture a sheep to raise, much earlier Maduo grass, and raised only 5 acres of pasture a sheep, but now a 1000 acre sheep pasture was actually raised to live. How shocking these figures.
Maduo no trees, and even a clump of tall wormwood almost see. Maduo of grassland degradation, and degradation of a group of yaks, sheep are degraded, there is no degradation of the animal was actually the only mice. Grassland rodent rampant, no grass, but covered with Euphorbia, Euphorbia is not only a poisonous weed, or an ominous warning of natural grassland degradation flowers, is a natural God sent to watch over the last line of defense but also to monitor the human virtues Yao Yi, a messenger. Three sources of the Yellow River has two drying up, even on music is the source card, over the years because of drought often drying up, water less, has no water or little water flows into the Zhaling and Eling.
Yellow River source is down year by year. There are only Zhaling water into the Yellow River and Eling. Even Eling Lake and the phase between the Yellow River Zaling, January 1997 to March of the Yellow River in the Yellow River Bridge, State Road 214 River drying, October 20, 1998 to June 3, 1999 Yellow In between Zaling and Eling stop again, and the drying time of up to six months.
Zhaling and Eling Lake water levels in recent years at an annual rate of about 1 meter drop.
