Improve the subjective and well -being, the construction of the green space in the residential area may be optimized

Greenland can not only provide subjective well -being for human beings, but also provide a variety of ecological services that are conducive to the environment and human beings. In recent years, the South China Botanical Garden of the Chinese Academy of Sciences has paid attention to the research field of harmonious development of human and nature. In the next step, the South China National Botanical Garden will take the Guangzhou residential area as an example to discuss how to reasonably configure green space to optimize its ecological service functions.

Greenland can provide human beings with subjective well -being

For urban people, Greenland can not only provide a variety of ecological services, effectively improve the ecological environment, but also improve the comfort of urban residence, which is beneficial to human physical and mental health. In recent years, many foreign scholars have discovered the benefits of green space through data measurement of blood pressure, saliva (containing components that are stressful), heartbeat, and skin conductivity.

In 2020, Dr. Liu Hongxiao, South China Botanical Garden Ecological Center of the Chinese Academy of Sciences, under the guidance of Researcher Renhai, collected residents' green space exposure indicators, natural connection indicators, and psychological health indicators. And the contribution of natural exposure to depression is greater than the degree of nature. This research that is closely related to the urban population reveals the impact of natural exposure and nature on psychological health, and has received support from research and development plan projects in key areas of Guangdong Province, National Natural Science Foundation of China, and Guangzhou Science and Technology Plan Project. Dr. Liu Hongxiao told reporters that there are some studies that through natural exposure, the symptoms of screen time and addiction can be reduced, such as quit games and mobile phone addiction.

Regarding the benefits of Greenland, Jiao Min, assistant researcher at the South China Botanical Garden of the Chinese Academy of Sciences, said in an interview that Greenland can not only provide a subjective well -being for human beings, but also provide a variety of ecological services that are conducive to the environment and humanity, such as fixation of oxygen to reduce air, reduce air Pollution and urban waterlogging, cooling down, noise reduction, improvement of biodiversity, and beautifying the environment.

The number of seven major benefits of urban green space one by one:

1. Solid carbon release oxygen. Plants reduce the carbon dioxide content in the air through photosynthesis, alleviate the effect of greenhouses, and correspond to the oxygen necessary for human survival.

2. Purify the atmosphere. Some plants can absorb pollutants in the air, such as sulfur dioxide, nitrogen oxide and ozone, etc., and can also "grab" the fine particles in the air (such as PM2.5, PM10) through the velvet of the surface of the blade surface (such as PM2.5, PM10). This reduces the emergence of haze weather.

3. Reduce waterlogging. Greenland has the ability to reduce surface runoffs and flood storage and flood storage. It is an important part of the urban sponge system and can effectively reduce the occurrence of urban waterlogging.

4. Adjust micro -climate. Greenland can clearly adjust the environment such as cooling and dampness and humidification through shading and transpiration, to alleviate the effects of urban heat islands, reduce the risk of health and heat in residents, and effectively enhance the residential comfort of the city.

Studies have found that the temperature of the darker areas (green space and its surroundings) is low, while the area temperature of centralized distribution in the middle building is obviously relatively high. (Photo confession interviewed)

5. Improve animal diversity. Greenland can provide habitats for animals, as well as "stepping stones" for animal migration. For example, a large number of migratory birds are migrated in Guangdong every year in winter, and there are many rare birds protected by many countries. The road of migratory birds to the south is long and can be reached overnight. Various types of green spaces on the journey provide them with temporary rest for them. "Set your foot".

6. Reduce noise. Now noise has become a major pollution in the city, and the green space can have an effective attenuation effect on noise. It is clear that in daily life, it can be felt that after entering the Greenland Park from the road with severe traffic pollution, the noise strength has a large strength. The decline of the amplitude seems to be quiet throughout the world.

7. In addition, Greenland also has a beautified environment, rest and entertainment, etc., flowers and trees can give people aesthetic enjoyment, make people feel happy and relaxed, and promote people to exercise, picnic, family gatherings in green spaces such as parks Waiting for useful activities.

Next step: It will explore the reasonable allocation of green space in Guangzhou in Guangzhou

The environment for the coexistence of the creator and nature is the common goal of human beings, and the research results of related topics are inseparable from the persistence and persistence of scientific researchers.

"Some of our research contents are 'eating by the sky'. For example, every time it rains, colleagues who study the floor runoff will immediately collect the tools to collect samples." Jiao Min said that some need to be continuous and high -frequency monitoring. The work requires researchers to squat next to the instrument for a long time. "When Sanfu Tian was specially exposed during the day, we will play a sun umbrella and squat next to the instrument. It is a whole day, and then go out for experiments and laughs as" mushrooms ". We will also bring a folding little horse to sit and shoot mosquitoes. "

Although Greenland has a variety of ecological services that are beneficial to the environment and human health, Greenland itself is facing great threats such as decreased coverage and single types, and it also has greatly damaged the supply capacity of green land ecological services. For example, at present, cities around the world are developing rapidly. On the one hand, a large number of green spaces are replaced by the impervious water of roads and buildings, and the coverage area of ​​green space has been greatly reduced. In addition, there are problems of significant reduction in the variety of green space plants.

Therefore, whether it is from the perspective of human ecology, the perspective of beautifying the urban environment, or the perspective of protecting biodiversity, Greenland has become a part of "harmonious coexistence of man and nature"."Our next step is to take the Guangzhou residential area as an example to discuss how to reasonably configure green space to optimize its ecological service functions." Jiao Min said, "We need to love green space and live in harmony with green space, so as to achieve health and can be healthy, so on.Continuous development.
