Speech on "Science and Technology Expo, Green Life"

Might as well clean it up yourself. There are many materials for reference. It's better to do it yourself. Provide information for reference.

The topic of my speech today is "Science and Technology Fair, Green Life".

Shanghai World Expo 20 10 will be a grand meeting to discuss human urban life in the new century. This is a place that people all over the country are particularly proud of and pay attention to. It is time to show our unity, to build a harmonious and beautiful society, and to carry forward the style and spirit of the Chinese nation!

At that time, countless revolutionaries crossed the ocean to seek ways to save the country and the people, and looked forward to national rejuvenation with the fearless spirit of "fighting for China with one heart and one blood". From Su Wu, who is unyielding in his death, to Yue Fei, a national hero who has caused great impact on the enemy, to Wen Tianxiang, who has lived endlessly since ancient times, and to Sun Yat-sen, who struggled to build a democratic China. And Mao Zedong, the great man who started a new era of socialism, and Deng Xiaoping, who awakened the eastern economy to take off ... What did they do? Only for the great cause of national rejuvenation! Now the society is prosperous, the living standard is improved, and science and technology are developing vigorously. The 20 10 World Expo held in Shanghai is the best evidence to comfort the martyrs!

As we all know, the 2005 World Expo will also be held in Asia, especially in economically developed Japan. The 2005 World Expo won the world's attention and moved! Now, the five-year World Expo will be held in Shanghai. Isn't this just a game, a silent contest? Therefore, to hold a successful World Expo, we must carry forward our national spirit. To carry forward our national spirit, we must start from me and start from small things!

Small things can be as small as giving someone a faint smile. You are smiling, this is a person's expression; Millions of people smiling together is the expression of a city and a society. A small greeting reflects a great love; A brief smile, sometimes it can be printed in the deepest part of people's hearts forever. Do you remember the unexpected troubles in the 5. 12 earthquake? "There was great love before the disaster", and the whole nation was United as one. True feelings are like a drop of water in the dry season. Although it is only a small drop, it can moisten a bud and keep a fresh green color.

It is gratifying that people's mental outlook is so harmonious: in public places, the queue is very long, no one cuts in line, no one quarrels, no one makes noise, and it is orderly; The staff saluted and thanked, and the professionalism was impressive. There are elevators in the park, and they are all polite. Bad habits such as spitting, using the road as a dustbin, running red lights and crossing the road are gradually disappearing. ...

The world is changing endlessly, each leading the way for hundreds of years. I firmly believe that as long as we carry forward the national spirit, start from me, start from small things, and present our best side and best posture to the world, the city will definitely make life better! Expo 20 10 will also be the most wonderful page in history!

Green life starts here.

-Feel the "low-carbon Expo" and "high-tech Expo"

Xx days, a feast of human civilization, will once again focus the world's attention on China, an ancient oriental civilization, on the land of 5.28 square kilometers beside the Huangpu River, and will once again write the glory and dreams belonging to all mankind. Nowadays, the beautiful Huangpu River is full of rich Expo flavor, and a magnificent Expo Park is rising on both sides of the Huangpu River.

At the same time, under the guidance of the theme of "Better City, Better Life", many advanced technologies and ideas are showing us a rich scientific and technological Expo feast. On this basis, the promise of building a "low-carbon Expo" has changed from a dream to a reality.

On the occasion of the countdown to the opening of the Shanghai World Expo 100 days, the reporter interviewed at the Shanghai World Expo and deeply felt the new changes and new enlightenment brought by the "low-carbon Expo" to our lifestyle.

China Model of "Low-carbon Expo"

Walking in the Shanghai World Expo Park, a series of high-tech technologies for energy conservation and emission reduction attract the attention of reporters at any time, and the details are amazing. As a vivid practice of implementing low-carbon economy, the construction of Expo venues has become a model for future architectural design.

In the green hall of the completed Permanent Engineering Expo Center, the reporter saw that the ecological vertical green wall of nearly 500 square meters in the central hall was covered with ferns and rattan grass, and the translucent LED display of 400 square meters was refreshing. In order to reduce building energy consumption, the design method of the north-south facade of the Expo Center is different from the traditional glass curtain wall. The north outer wall adopts a large-area transparent glass curtain wall, which makes full use of natural lighting as much as possible and can enjoy the beautiful scenery of the World Expo Park and Pujiang. The south exterior wall is designed with self-shading facade, which can block the direct sunlight in summer.

Chen Chengsheng, general manager of the Expo Center project, said that in order to achieve energy conservation and emission reduction, the total installed solar energy capacity of the Expo Center reached 1mw, and many energy-saving and environmental protection technologies such as led lighting, river water source, ice storage, water storage, rainwater collection, permeable concrete and permeable bricks were adopted, and its energy system was the most complicated in China.

From the steel mills with black smoke and roaring machines at first to the 37 hectares of green space, the Expo Park and Houtan Park can be called the "green mile" of the Shanghai Expo Park. These two green "sister flowers" have adopted a series of advanced bio-ecological restoration technologies. Without the use of chemicals and special equipment for treatment and filtration, 2,400 tons of Huangpu River water flowing into the park every day can be purified from "natural" water that is inferior to category 5 into three types of water that can be touched for waterscape, greening irrigation and road washing in the park, without consuming precious tap water.

Strolling along the Expo axis that stretches for more than one kilometer, the "Sunshine Valley" with six trumpet-shaped openings is particularly eye-catching. These "morning glory" collect sunlight and store rainwater, which will provide 7000 cubic meters of irrigation and clean water for the Expo site. The brand-new semi-open architectural form of Expo Axis introduces air, sunshine and green into the whole four-story space, which significantly improves the environment, air quality and comfort of underground space, even if tourists are in the basement, they will not feel depressed.

According to Hong Hao, director of the Bureau of Shanghai World Expo Coordination, the installed capacity of solar power generation in the Expo Park has reached 4.5 MW, making it the largest demonstration area of solar photovoltaic cells in China. The public transportation system in the park uses clean energy vehicles such as electric vehicles and supercapacitors, which makes the public transportation in the park "zero emission". There is a square kilometer of greening and park in the park, accounting for one third of the whole park fence area. Experts estimate that from before the opening to the end of the Expo, the above measures can offset 60% to 70% of the carbon emissions of the Expo.

World Thinking on "Low-carbon Expo"

The efforts of "High-tech Expo and Low-carbon Expo" will light up the theme of "Better City, Better Life". Public opinion at home and abroad believes that this World Expo will bring new enlightenment to the sustainable development of China and even the whole world. From the exhibition cases of pavilions and urban best practice areas around the world, we can feel the same concept of green environmental protection everywhere and conceive a beautiful blueprint for future urban life.

At the entrance of the 3,000-square-meter spiral ramp of the Danish Pavilion, there are conspicuous and unique exhibits-bicycles, and a pond that is about to pour into the clear water of Copenhagen Harbor. After the opening of the Expo, the audience can experience the "low-carbon life" in northern Europe: riding a bicycle, or taking off their shoes and socks, soaking their toes in clear seawater and enjoying the coolness in summer.

In the urban best practice area, Sun Liansheng, director of the urban best practice area of the Shanghai World Expo, introduced various construction cases: "The Hamburg House in front of us is a new light-resistant building project, which brought the concept of' passive house' to Shanghai and even China for the first time. This low-energy residential building with a building area of 3 1.50 square meters and a cost of 42 million euros will be self-sufficient in building energy by absorbing clean energy such as solar energy and geothermal energy. The inductive power switch inside can be turned on or off with people coming in and out, and its energy saving standard is as high as more than 90% of similar buildings. "

It is understood that the four indoor exhibition areas in the urban best practice area were converted from four old factories in Shanghai Power Plant. The reporter saw at the scene that four factories have been transformed into four beautiful art buildings, one of which has been covered by a reddish-brown earth shell, which is inlaid with many exquisite hollow geometric patterns, and the factory next to it is decorated like a beautiful white snow by a layer of snow-white film. Sun Liansheng said that this kind of membrane is waterproof, fireproof and anticorrosive, and it is one of the best membranes in the world. Not far away, the main engine room of the 30,000-square-meter old power plant has also "transformed". It will be used for the exhibition of the future pavilion, new energy pavilion and lecture hall of urban best practice area of Shanghai World Expo. The towering chimney at the top of the factory will be transformed into the largest thermometer in the Expo site, providing visitors with accurate weather information.

From livable homeland, sustainable urbanization, protection and utilization of historical heritage to scientific and technological innovation of the built environment, the concepts and practices of "low-carbon Expo" and "scientific and technological Expo" of the Shanghai World Expo will make our sky bluer, our land greener, our water cleaner and our city better, open the window of China's scientific development and build a platform for the world to look forward to the future.
