We can see a newly emerging community now: where there are supermarkets, schools, banks and so on. Without doubt several years ago, it was still the countryside.

Some experts say that urbanization does not necessarily have a city disease, have a disease is rooted in the guiding ideology of one-side, unreasonable industrial structure and layout,”low-density

expansion”,approach the development of city to overcome the disease,”plan to reduce urban disease”and “management and treatment the city disease”. The opinion was justified, but the problem is that can we guidelines one-side in practice? Can practive in a rational science? Can management be done strictly in place? Such as this summer in Beijing, a storm almost paralyzed the city traffic and in Shanghai, a strong wind and heavy rain that serious traffic jams and large-scale blackout happened.

the third point is the real estate”bubble”. Housing in many cities are too many and built up too quickly now. It has occupied a large number of bank funds. There will be a large number of houses left vacant and leading to economic crisis if severe over supply or the price exceed capacity of the public. Experience shows that the real estate bubble caused by the economic crisis take years to be back to life.

fourthly, last but the most important point, which is a the modern problem of human concern : “The environmental issues. Now, regardless of what is in the newspaper or on thewebsit or on TV there will always be some reports of environmental pollution that are caused by disasters. The most prominent is the issue of urban pollution: and one topic needing attention is the outstanding water pollution. Due to rapid urban population growth and rapid development of industry, a lot of water has not been properly dealt with and is put directly into the river.This causes serious damage to the water environment.

From the point of views mentioned above, urbanization is like a balancing glant. On the one hand it promotes socio-economic development. On the other hand rapid urbanization will lead to the environment of human existence being devastated. It needs to find an equilibriurn that balances both sides. It not only enhances the socio-economic development but also minimize environmental pollution. But, what is the balance? And how to find the right one for effective?

In general, the pace of urbanization should be robust and should maximize the benefits of urban expansion. We should avoid careless and blind thoughts about the disadvantages. There are some methods such as : promoting cycling and reducing by cars. This will not only reduce vehicle exhaust emission but also conserve the thenon-renewable resources of oil. We should raise awareness of human pollution, recycle waste by classification and strengthening the management of waste emissions from industrial enterprises and forth.

Overall, urbanization is disadvantages more than its advantages .The government must plan for urban growth and development. It must make policies that will enhance sustainable land use and minimize ecological degradation. Urbanization is a cross-road which governments cannot ignore.
