Creating a good living environment is a common concern in the world, and it is also the focus of increasing attention in our country recently. Especially since 2005, the theme of this year's World Environment Day is, "Build a world city and protect our planet."

”, and forums on green and harmonious Habitat Festival and human settlement environment were also held this year.

On the eve of World Habitat Day on October 3, the "2005 Global Human Settlements Forum" was held in Shenzhen at the end of September. Due to the special adviser to the United Nations Secretary-General Annan, the United Nations Deputy Secretary-General, and a leading figure in the global environmental community, Maurice Sturt

The attendance of a number of well-known domestic and foreign experts such as Lang Lang attracted special attention, and some brand-new views and concepts frequently emerged from the forum.

"The sustainable development of our global civilization mainly depends on the successful transformation of cities to the path of sustainable development. The progress and scale of China's urbanization are unmatched by other places in the world, and there is no sign that this process will

It will slow down,” said United Nations Deputy Secretary-General Maurice Strong.

Zhu Tiezhen, a well-known expert on urban issues, vice chairman of the China Urban Development Research Association, and researcher at the Institute of Economics of the Chinese Academy of Social Sciences, asserted, “In the 21st century, a city that is not suitable for modern people to live will be eliminated. A city that suppresses and restricts people will be eliminated. Cities that are creative and developing will inevitably decline.” He pointed out that “cities must choose a win-win strategy of developing the economy and protecting the environment.” 1 Protecting the environment will not hinder development. At present, industrialization and urbanization have become the key to China’s national economic and social development. It is an important carrier and the only way for the country to achieve a moderately prosperous living standard. However, my country's urbanization and urban development are also facing major problems - the dual challenges of economic development and environmental protection.

Professor Zhu Tiezhen pointed out that development and environment are inseparable. Since the industrial revolution, economic development and environmental protection have formed a sharp contradiction.

Due to improper selection of development models, economic development also brings serious environmental problems, which in turn restricts economic development.

According to incomplete statistics, the direct economic losses caused by environmental pollution usually account for about 5% of the GDP. Therefore, it is urgent for cities to transform the economic development model and economic growth mode, efficiently use energy and resources, protect, repair and improve the ecological environment.

urgent task to solve.

Zhu Tiezhen believes that the key to whether a modern city can develop sustainably lies in whether economic and social development can be coordinated with the natural environment, whether it adheres to the scientific outlook on development, and continuously improves the urban living environment and humanistic environment.

Urban environment is a scarce resource, which is the foundation and prerequisite for the existence and development of cities.

Human civilization and progress require the development of cities, and human survival and development require a good environment. The two are opposites, but they should be unified with each other.

Therefore, cities must choose a win-win development strategy for economic development and environmental protection.

Experts point out that protecting the environment will not hinder development. We can also find some economic growth points that can promote the development of the environment while developing the economy.

2. Science and technology is a sustainable positive force. “For positive and sustainable development, science and technology is very necessary. In China’s 5,000-year history, China’s history of scientific and technological inventions is also very prominent in the world, so China should have the ability to

Be prepared and have the wisdom to make changes in the process of urbanization." Several international environmental experts used a large number of facts to confirm and emphasize the positive power of science and technology when explaining how to deal with environmental issues.

For example, in Santa Monica, the central area of ??Los Angeles, USA: half of the vehicles have been converted to use natural gas and other environmentally friendly energy sources; the first solar-powered Ferris wheel has been built; and it is now working with other companies in Southern California.

Five cities have cooperated to promote renewable energy projects that obtain hydrogen fuel through electrolysis of water. Some newly renovated public houses and private houses have used natural gas and hydrogen to become green buildings; the use of solar energy in private houses can reduce 2/

3 energy consumption and reduce pollution emissions; a rainwater collection and circulation system is installed under the playground and other places to collect rainwater for flushing toilets. If all these facilities were built, the entire city would not spend 4 billion US dollars to control rainwater.

pollute.

In Beijing, 3,000 buses already use natural gas to reduce environmental pollution.

A recent advancement in technology is the use of membrane technology in the water filtration process, which can make water circulation more efficient and economical.

It can be said that technology is a positive force in building a sustainable human settlement environment.

3 To improve human settlements, public services are the focus. What are the basic requirements for building an urban human settlement environment?

Zhu Tiezhen gave the following answer to this question.

The construction of urban human settlement environment, first of all, should be based on meeting the needs of urban residents and embody the people-oriented principle to the greatest extent.

Second, safety should be a prominent factor in the living environment.

Modern cities must put safety in an important position, such as flood prevention, earthquake prevention, fire prevention, traffic accident prevention, emergency accident prevention, etc., all of which are indispensable for an ideal living environment.

While urbanites enjoy the civilization brought about by modern development, they must also carefully guard against the consequences of natural revenge and man-made destruction.
