Over 20 years, scientist and the engineers start resolve Shanghai to sink to decline a problem, adopted restriction to pump water at that time of some measure, Shanghai strengthenned these measures in 2003.Request an each dozen an one mouthful a deep well, all want official permission.
Currently, mining groundwater the quantity has already had a control, the capacity of every year is 100,000,000 sign a square rice, pass these restrictions, city hall in Shanghai and related sections in the joint effort now.With decelerates the speed that Shanghai descends to sink further.
Because 20 centuries second half leaf to excessively open up of the land, big 兴 the Anne 岭's south forest edge has already retreated 200 kilometers at least, the big 兴 is one of Chinese main LIN2 QUs, there is much waterfalls in its south region, very in keeping with farming.
In the past 50 years, a great deal of forest of this regions encounter to the breakage, is open up to become farmland, according to big 兴 environmental protection the expert say, 200 kilometers of just retreat to distance in big 兴 south of keep to calculate.
The big 兴 LIN2 QU's area descend, cause the soil erosion and the river bed dried up, some places in Inner Mongolia, plant ever and thickly quilt, have already disappeared currently.A lot of rivers are already a year river often, now indeed decline the water but dried up because of lack.
In the past decade, Shanghai with equally sink to decline about 16 millimeters speed annually, with since 20's in 20 centuries, center city area in Shanghai about 600 district of the square kilometers have already equally descended to sink 2000 millimeter, some places even come to a 3000.
As early as 1921, the geologist discovers Shanghai is descending to sink, the expert thinks consistently, a main reason that sinks to decline is a groundwater to mine excessively, moreover, the fast increment of the city center skyscraper is also one of the reason that Shanghai sinks to decline.
Though this region forbids to open up in great quantities now, some farmers try to extend their farmland still, so forest still Be being eroded gradually, the national forest management bureau will launch inquisition, looking up a responsibility person who result in now situation.
Pay attention to increasingly to the environment problem along with the international society, the environmental protection industry develops rapidly within the scope of world, the flourishing and national environmental protection industry increases annually 100 divide 6, but in East Asia with pulled this numeral of a little bit beautiful developing countries to then exceed 100 divide 10.
The environmental protection industry of China also in the booming development, since recent more than 10 years, the Chinese government promotes environmental protection strongly, in this kind of case, the environmental protection industry development is quick, having already become national economy an importance to constitute part.
The Chinese environmental protection industrial structure unbalance, the environmental protection service, the environmental protection product, the market of[with] the environmental protection technique and the environmental protection funds needs a further development.The Chinese environmental protection industry contain huge potential, but have to adopt some measure to come to well exertive this kind of potential.
After big dam in Yangtse gorges starts retain water, fluid matter in Yangtze River has no occurrence variety.The wreath 卫 worker already from the water level river bed top clearance 1,990,000 ton garbages, 1,980,000 ton industrial waste, and 1500 ton dangerous odd-come-short, and carried on disinfection to 5,000,000 all toilets in the square meters.
The environment learns an estimate, fluid matter in Yangtse gorges still will keep national x-rated level, however start soar along with the reservoir water level after retain water, the water current speed reduces slowly, river the by one's own sweep of the water ability will have to descend.Therefore, reservoir in Yangtse gorges still faces a huge challenge.
Decade in aftertime, China will invest about 400 忆 renminbis in the database area of Yangtse gorges, about 忆 US$48.The cent criticizes to build up 150 processing factories a processing factory with 170 city garbage, anticipate can handle this region 100 divide 85 above waste water and the garbages.
First stage, heavy celebrate to have already set up 19 dirty water processing factories with 13 garbage processing factories, they win of greatly part of will throw in movement before the reservoir water level soar to 135 meters.Locate the database area about 1000 severity pollution business enterprises to have already been close moreover

Since 20 years, the scientist and engineers have started to solve
Shanghai's subsidence problem, at that time has taken some measures
which the limit pumps water, in 2003 Shanghai strengthened these
measures. Requires an each dozen deep well, all wants the official
permission.

At present, already had the check to the ground water mining quantity,
every year limiting the quantity was 100 million cubic meters, through
these limits, the Shanghai government and the correlation department
joint effort. To further slows down the speed which Shanghai sinks.
Because 20th century next half to the land excess reclamation, south
Daxinanling the forest edge already at least retroceded 200
kilometers, energetically was one of Chinese main forest regions, its
south zone has very many waterfalls, extremely suits cultivates.
