Green space and health
The contribution of green spaces is not only for the environment. At the same time, it affects the mental and physical health of people. It is a necessity for modern cities and an important concern for society.
In a phase of rapid urban development, human beings are faced with sub-health problems and epidemics in large cities are gradually becoming younger. What is more evident is that during the epidemic, human beings who are confined to their homes, carry out activities in a limited space, such as eating, resting, networking, studying, working, etc.Confined spaces bring emotional anxiety, fear and physical illness to human beings, and nowadays city dwellers are keen on green spaces outside because they bring unexpected joy, comfort, increased social interaction and expanded emotional and psychological communication between neighbours.Therefore Healthy urban planning is particularly important, and community gardens are also a breeding ground for city dwellers.
Creating a healthy, safe and natural community green space in a green space is essential for epidemic prevention and control and public health through appropriate spatial layout and design.
As an urban design planning practitioner, the following points need to be considered in relation to green spaces in communities
1.What advantages can green space bring to people and the environment
2.What is the human need for green space?
3.What are the types of people and what are their ages?
4.How can community green space be planned appropriately?
Community Green Space
For community green spaces, the arrangement of green spaces is not easily too narrow and fragmented in order to achieve ecological balance, ensure their connectivity and promote the interaction of green spaces. Some of the space in the green space is used to allow people to move around. For example, rest, camping, recreation, it is a free space.

In order to provide residents with more sensory stimulation, the ecological benefits of the plants are combined with a rational layout and spatial organisation of the green space to isolate the polluted air from the outside.Plants have the power to kill bacteria, release oxygen and purify the air, for example: lilac, lemon, camellia, lohan pine, sea tree, camphor, black pine and boxwood, improving the quality of the environment and making humans healthier physically and mentally.

Green event space
The combination of green and active space makes for a healthier body and stimulates people to get outside and play sports in a green environment.The layout of the site takes into account the direction of wind currents, arranging plant communities with high absorption capacity to allow air purification and noise reduction, and the sparseness of plant spaces to give a healing effect to the landscape.Inside the activity space, leisure tables and chairs can be arranged, free space for activities, so that people can move around in the green space and increase the amount of time humans spend in the outdoor space.

Depending on the population of the community, we have set up therapeutic garden facilities, horticultural therapy activities and a civic garden to grow vegetables, fruits, plants, etc.For people interested in using the courtyard for therapeutic purposes, this therapeutic practice is aimed at children, the elderly, the disabled and the less able.it can promote growth, improve the intelligence of the imbecile, eliminate trauma and interact with nature and horticultural crops as the core of communication.
