China's urbanization is entering an accelerating period according to the newly published 2009 City Development Report of China, an annual report conducted by China's Association of Mayors, the Xinhua News Agency reported.

Nearly 621.86 million people lived in cities in 2009, and the report estimates that by 2020, almost 50 percent of the Chinese population will live in cities, and by 2050,the percentage would grow to 75 percent.

The report mentions that during the past 60 years, China's urbanization pace has accelerated rapidly, from 10.6 percent in 1949 to 46.59 percent in 2009; the number of cities grew from 132 at the beginning of 1949 to 655 by 2009.

However, the world average urbanization ratio is 50 percent, and in developed countries 85 percent, and China's urbanization still lags behind the industrial development, which leaves huge room for further development.

Will the density of population per sq km lower then?
Will the drainage system efficient enough then?

At present, when it rains heavily, some streets of many cities have the road traffic inconvenient problem due to overflowing water.

Yes, urbanization tends to reduce WATER ABSORPTION, i noticed that too!

The Bigger the city, create BIGGER HEAT ENGINE if without trees!
and COOLER city centre BY evening, so BIGGER convection rain.
Especially true in coastal region, or region next to large lakes!
(meaning most of China!!!!)

Ms. Amy, so China has 47% Urban registered HUKOU population, and 10% floating population in 2010? - that's 57%!!!

Yes, flood alleviation projects will cost BILLIONs of Rmb!
Lots of "counter cyclical spending" too!
You need DEEPER DRAINAGE, need to build Flood Retention ponds and even tunnels to rid of access water from the flood retention ponds. BIG CIVIL CONSTRUCTION jobs!

brrrrrrrr! Crazy world we live in!
Solve 1 problem, next crops up!!!!
and we still haven't solve all the SEWAGE, heating, pollution, noise, pedestrian movement........

ARGGGGHHH!

..AND the Americans are pitting Asian Trade Route states..

...to encourage more military spendings! The Americans, with British help try to either secure the cheapest crude oil production in the world - Arab Gulf - or just make the area UNGOVERNABLE! That would limit the volume of crude oil China can import, so limiting Economic size!

Maybe cause crisis or clash East Asian States as well!


Arghhhhh!

Deeper drains (bigger volume capacity), Flood water collection ponds....not roof!
We have already heard of urban floods in Guangzhou for years and years already......

rain collected on roof top to use in toilets, washing vegetable... save water , less pipes under the road transporting water in a longer way.

I think you can limit the population of those metropole cities and stop them from expanding too fast by means of encouraging more people to move to other cities
