Shanghai is not suitable for people to live in

Shanghai is uninhabitable. Pudong and Fengxian are ok.

Puxi is too bad.

The city center is also poor.

Shanghai has an east wind, a northeast wind and a southeast wind all the year round.

So from the perspective of urban planning,

The east is the upper air outlet, with less pollution.

Due to historical reasons, some small environmental cities are poorly planned, so it is not suitable to place heavily polluting enterprises. Avoid nearby flavor factories, electronics factories and battery factories, and stay away from mobile base stations, power stations, high-voltage lines and main roads, which are basically enterprises that emit noise, radiation and pollutants.

Many decibels are the most suitable and unsuitable for human habitation. According to the "People's Republic of China (PRC) Urban Regional Environmental Noise Standard", the standard value of environmental noise of houses, cultural and educational institutions and rural residential areas is 55 decibels during the day and 45 decibels at night. The equivalent noise value of industrial and commercial mixed zone is 60 decibels, and it is 50 decibels at night; On both sides of the main traffic lines in the city, the equivalent noise value of noise during the day is 70 decibels, and it does not exceed 55 decibels at night.

According to medical experts, under normal circumstances, if the noise exceeds 50 decibels and people stay in this environment for a long time, the nervous system will be affected. For every 3 dB increase in noise on average, the noise energy will double. Noise pollution is serious and even damages people's hearing system. Often troubled by noise, there will be symptoms such as memory loss and insomnia. Studies have shown that the proportion of women who live or work near airports and railways for a long time who give birth to mentally retarded and deformed babies after pregnancy is significantly higher than that in other regions.

The maximum noise of each construction activity is specified here, such as 92 decibels for carpentry and 85 decibels for pulverizer. When the noise in the construction site exceeds 140 dB, some machines must be shut down. In some cities in developing countries, the problem of noise pollution is becoming more and more serious, and the noise in some areas reaches 75-80 decibels all day.

Research shows that the maximum acceptable volume of human hearing is 30 decibels. When indoor noise pollution exceeds 30 decibels, people's normal sleep will be disturbed, while living in a noise environment above 70 decibels will affect people's hearing and health. The latest scientific research confirms that noise can also harm people's eyes, causing visual fatigue and vision loss. When the noise intensity is 90 decibels, about half of people will have dilated pupils and blurred vision; When the noise reaches or exceeds 1 10 dB, the adaptation of almost everyone's eyes to light brightness is weakened to varying degrees. This is why people who live in noisy environment for a long time are particularly prone to eye fatigue, eye swelling and pain, eye hair and tears.

100 meter is not suitable for human habitation? The height of 100 meter is suitable for human habitation. Civil buildings with a building height greater than 100m are super high-rise buildings. Super-high-rise building refers to a building with more than 40 floors and a height of 100 meters. However, due to the poor safety of super high-rise buildings, it is rare.

At the 1974 International Conference on High-rise Buildings, the United Nations Department of Economic Affairs classified high-rise buildings into four categories according to their heights:

9 ~ 16 layer (up to 50m);

17 ~ 25th floor (up to 75m);

26 ~ 40th floors (maximum100m);

More than 40 floors (the total height of the building is greater than 100 meters, that is, super high-rise buildings);

High-rise building usually refers to a building with many floors and high height, but different countries have different regulations on how high it is.

Why Mars is not suitable for human habitation? Without a stable magnetic field to protect what we need in life, the earth has a magnetic field to protect us from the solar wind.

Which place is suitable for people to live now! Weihai ranks first among the top ten livable cities in China, Zhuhai ranks second among the top ten livable cities in China, Guilin ranks third among the top ten livable cities in China, Guiyang ranks fourth among the top ten livable cities in China, Taizhou ranks fifth among the top ten livable cities in China, Beihai ranks sixth among the top ten livable cities in China, Qinhuangdao ranks seventh among the top ten livable cities in China and Yichang ranks seventh in 2005. China's top ten livable cities ranked eighth, Xianyang ranked ninth in China's top ten livable cities and Qujing ranked tenth in China's top ten livable cities.

From the perspective of geomantic omen, is the East House not suitable for people to live in? As the saying goes, if you have money, you won't live in the east wing. It is not warm in winter and not cold in summer. In other words, in winter, the east room is directly blown to the doors and windows by the northwest wind, which is not easy to keep warm; In summer, it is sunny all afternoon in the west, and the temperature is very high, which makes people very uncomfortable. Therefore, the east wing of quadrangles is often used as a study room, a guest room and/or a kitchen and dining room, without emphasizing geomantic omen.

Is the ocean suitable for human habitation?

Yunnan in China is not suitable for people to live in, so it's natural how the climate is ~ the conditions in all aspects are also very good, and the weather in Yunnan is also different. If the four seasons are like spring, Kunming, Yuxi and Chengjiang are better ~

What are the worst places to live in China? For example, places with harsh natural conditions such as desert Gobi, places with frequent natural disasters, and places with fragile ecology that cannot withstand human development, production and life.

In the future, people can move to other plasmas, including Mars. What's life like on Mars? Let's go and have a look. It's morning on Mars, and you wake up in the bed of the space capsule. You don't have to make the bed, but the robot will do it. You have a special breakfast, which is made from Mars. After eating and drinking enough, you are ready to go out. At this moment, you need to wear a mask that can protect you from thin air and strong storms. People here live in space capsules, and you can visit them in a carriage. At that moment, you saw a lot of things you are familiar with. Yes, it's your hometown. Smart people have built many things that are the same on the earth to commemorate them. After the visit, you can't forget what you saw. It's not a dream, but it will happen in the future. Let us look forward to this day!
