Over 90 % of Shenzhen citizens choose public transportation

784,000 tons of low -carbon public travel reduction reduction displacement is equivalent to the absorption volume of 39,200 hectares of forest land. This is the answer sheet of Shenzhen Metro Group in 2021 for energy conservation and emission reduction. In -depth reporters learned from the Shenzhen Metro Group that the Shenzhen Metro fully excavated the energy -saving potential of equipment, explored the innovation of energy -saving technology innovation, and made green travel green.

Travel per person by subway

Reduction 0.0467 kg carbon dioxide

It is understood that the subway, as the aorta of Shenzhen public transport, accounts for more than 60%of the public transport sharing rate. Since the first phase of Shenzhen Metro Line 1 in 2004, the first phase of the Shenzhen Metro Line 1 has been completed. Today, the mileage of the Shenzhen Metro Line Network has reached 419 kilometers, with an average daily passenger flow of 5.9689 million people.

In 2021, about 16.8 billion kilometers of transportation services were provided. According to the accounting method of "Shenzhen Low -Carbon Public Travel Carbon Benefit (Trial)" released by the Shenzhen Ecological and Environment Bureau in December 2021, take every subway for every subway People can be reduced by 0.0467 kg of carbon dioxide. The Shenzhen Metro provides about 784,000 tons of low -carbon public travel carbon reduction reduction, which is equivalent to the absorption of 39,200 hectares of forest land. The green ecological benefits are significant.

This is naturally inseparable from the choice of Shenzhen citizens. The "Digital Tools to help public green travel research reports" released by the Ministry of Ecology and Environment show that over 90 % of Shenzhen citizens travel daily travel to public transportation, and Shenzhen citizens are also using actual actions to contribute to energy conservation and emission reduction.

Save water land

Deeply digging green low carbon potential

The subway is a public transportation system operating electrified. It is a synonym for green and low -carbon. However, even if it is a brand with "green travel", the Shenzhen Metro is still constantly tapping the energy -saving and emission reduction potential in subway operations and innovating emission reduction technology.

According to the relevant person in charge of the Shenzhen Metro Operation Group: "How to save energy, land, and water -saving in the full life cycle of subway operations to achieve safe and efficient loading passengers while reducing the environmental pollution. The direction of the subway is working hard. We deeply realize that Shenzhen's land resources are scarce, actively study the efficient use of land, and innovate the development model of land. "The person in charge introduced, such as the Liango Mountain vehicle section adopts intensive design, including double layers, including double layers The parking list, three -layer joint maintenance library, etc., saved 70%and 60%of land resources, respectively.

The person in charge introduced that the Shenzhen Metro automotive car washing machine used circulating water for train cleaning, using clean water at high -pressure water rinse and side refinement processes, accounting for about 20%of the total water consumption. The process uses the medium water after the sedimentation filtering treatment, achieving the effect of saving water.

In addition, the vehicle section of the Shenzhen Metro Line 6, Wangji Lake Parking Line 8, and Liang Hao Mountain vehicle section of Line 10 take sponge city measures to effectively reuse the water resources. Among them, the Changzhen vehicle section has set up rainwater garden, green roof, high flower bed, multi -functional storage pool (landscape lake), permeable pavement and ecological parking lots, ecological detention bands, and ecological storage ponds, becoming the first large -scale domestic scale in China The integration of sponge city technology with rail transit construction is used to apply it to the project of the subway vehicle section.

Develop energy recovery

Motify your brain for "power saving"

Since the third phase of the project, the Shenzhen Metro has comprehensively adopted a number of energy -saving technologies such as LED lighting technology, air -conditioning ventilation frequency conversion energy saving technology, escalator frequency conversion energy saving technology, and used the energy management system to achieve automation of energy consumption statistical analysis.

According to the relevant person in charge: "Through the intelligent lighting system, the Shenzhen Metro has realized the switch control, decentralized centralized control, use mode and the linkage control of other equipment systems." According to reports, Shenzhen Metro The public lighting system conducts LED lighting and transformation, the power saving rate can reach 58.7%, and the energy consumption can consume 11.42 million kilowatt -hours per year. The Shenzhen Metro uses variable frequency air conditioners. The use of ventilation frequency conversion energy saving technology can achieve effective adjustment and control of temperature. Beginning in 2020, Shenzhen Metro has implemented "different temperatures in the same vehicle" and set up "strong cold" and "weak cold" cars on the train. While providing differentiated services to citizens and passengers, energy conservation and emission reduction have been achieved.

Shenzhen Metro attaches great importance to the use of clean energy and the recycling of energy. It is understood that the roof of 12 elevated stations at Shenzhen Metro Line 6 has a distributed photovoltaic power generation system. The total power generation is expected to be 58.56 million kilowatt -hours during the 25 -year design life period of the system, and the carbon dioxide reduction is 225,800 tons. Shenzhen Metro Line 6, 8, 10 traction power supply system uses regenerative braking energy feedback device, which can directly return the energy generated by the train braking to the power grid in real time. For the online absorption and utilization of energy, the total annual feedback power of the three lines is about 12 million kilowatt -hours, and the energy saving effect is obvious.
