It is steadfastly believe by this author: First, “ trade with the income. “ . The income in big countries is certainiy higher than that in little countries. Intuitively, the urban income is more than that in the countryside.For illustration, Shanghai occupants in China, generaliy speech production, have higher life criterions than those in other metropoliss. Second, when incrcasing Numberss of people flood into metropoliss, the metropoliss are frequently going larger and many people move out of the downtown country into the suburbs. This tendency of urban building is good to the future metropoliss development as whole. Third, it provide development chances for large metropoliss. With more people coming to the metropoliss, urban development is sing a new unit of ammunition of jumping forward.

In general, urban development is of import for national economic system development attack. While the economic system is the degree for the index of a state, urbanisation is good for us ( Debroy,2009 ) .

Everything has two sides ; as a balance, since it has a good side there must be a bad side. Then, what countries negative impact of urbanisation on?

“ Firstiy, a big sum of non-normal cultivated land has decreased, metropoliss are built in the field where has good natural conditions and it is besides bulit in the best agricultural countries. By be aftering, Chinese urbanisation will affect taking the national land 3 % to 6 % . The ratio seems to be little but the size is non little about 300 1000 to 600 1000s square kilometer, which is equiralent to one-third or the half in Chinese field of the entire country. In fact, due to fast the development of urbanisation, enclosure manner is still prevailing. With the big figure of luxury works, edifices, assorted ” image undertakings ” the big Fieldss and big piece of lands of former farming area disappeared, so many people in China had small cultivable land and the struggles become more outstanding. Merely in recent old ages, the net loss reached 3800 million of cultivated land, this is the ground that consequences in a big figure of landlessness, joblessness, insecure husbandmans and nutrient production and consecutive landslide.

Second is the issue of how urbanization.Urban growing is excessively fast and the metropoliss are developing even larger with inordinate concentration of population traveling to the metropolis in a short time.It necessarily generates a big figure of unemployment, deficit of fresh H2O and energy supply, traffic congestion, increased offense, environment debasement and increased hazard of assorted crises of phenomena. Some experts say that urbanisation does non needfully hold a metropolis disease, have a disease is rooted in the steering political orientation of one-side, unreasonable industrial construction and layout, ” low-density

enlargement ” , approach the development of metropolis to get the better of the disease, ” program to cut down urban disease ” and “ direction and intervention the metropolis disease ” . The sentiment was justified, but the job is that can we guidelines one-side in pattern? Can practive in a rational scientific discipline? Can direction be done purely in topographic point? Such as this summer in Beijing, a storm about paralyzed the metropolis traffic and in Shanghai, a strong air current and heavy rain that serious traffic jams and large-scale blackout happened. These incident exposed the urban building and direction of our job is non try. “ ( Bnden,2010 )

the 3rd point is the existent estate ” bubble ” . Housing in many metropoliss are excessively many and built up excessively rapidly now. It has occupied a big figure of bank financess. There will be a big figure of houses left vacant and taking to economic crisis if terrible over supply or the monetary value exceed capacity of the public. Experience shows that the existent estate bubble caused by the economic crisis take old ages to be back to life.

fourthly, last but the most of import point, which is a the modern job of human concern: “ The environmental issues. Now, irrespective of what is in the newspaper or on thewebsit or on Television there will ever be some studies of environmental pollution that are caused by catastrophes. The most outstanding is the issue of urban pollution: and one subject necessitating attending is the outstanding H2O pollution. Due to rapid urban population growing and rapid development of industry, a batch of H2O has non been decently dealt with and is put straight into the river.This causes serious harm to the H2O environment. The following type of pollution is the serious impairment of air quality. The rapid development of industry, transit and heavy usage of fossil fuels has cause a serious impairment in air quality by dust, S oxides, N oxides, C oxide, ozone and other substancese into the ambiance. The 3rd pollution isoue is that of trash, were solid waste flooded and refuse is serious besieging. Human life and production have created big sum of solid waste. At soon, China produces 660 million dozenss of industrial solid waste every twelvemonth. There are 3000 to 4000 dozenss of risky waste in it, accumulated more than 64 million dozenss and it is busying more than 500 million square metres land. Annual copacity of one ton of refuse and an one-year groth rate is 7 % to 8 % . “ ( Wang, 2000 )

From the point of positions mentioned above, urbanisation is like a reconciliation glant. On the one manus it promotes socio-economic development. On the other manus rapid urbanisation will take to the environment of human being being devastated. It needs to happen an equilibriurn that balances both sides. It non merely enhances the socio-economic development but besides minimise environmental pollution. But, what is the balance? And how to happen the right 1 for effectual?

In general, the gait of urbanisation should be robust and should maximise the benefits of urban enlargement. We should avoid careless and blind ideas about the disadvantages. There are some methods such as: promoting cycling and reduction by autos. This will non merely cut down vehicle exhaust emanation but besides conserve the thenon-renewable resources of oil. We should raise consciousness of human pollution, recycle waste by categorization and beef uping the direction of waste emanations from industrial endeavors and Forth.

Overall, urbanisation is disadvantages more than its advantages.The authorities must be after for urban growing and development. It must do policies that will heighten sustainable land usage and minimise ecological debasement. Urbanization is a cross-road which authoritiess can non disregard.
