It refers to green space that has a direct impact on the urban ecological environment, urban landscape, and biodiversity conservation.

Legal analysis: The Code for the Design of Urban Green Space has been revised, and the original provisions of the revised article are repealed at the same time.

Legal basis: The announcement of the Ministry of Housing and Urban-Rural Development on the issuance of partial revisions of national standards is hereby approved by the "Code for the Design of Urban Green Space" GB50420-2007 partial amendment, and the original provisions of the revised Xiangtang are repealed at the same time.

Protecting the environment is everyone's responsibility.

Content: Urban green space system planning is an activity that qualitatively, positionally and quantitatively arranges various urban green spaces to form a green space system with a reasonable structure, so as to realize the functions of ecological protection, recreation and leisure and social culture of green space.

The layout of urban green space system refers to the unified consideration and reasonable arrangement of urban green space (including park green space, production green space, protective green space, affiliated green space and other green space) and road greening and water greening as well as important ecological landscape areas in the planning to form a certain layout form.

The layout of the urban green space system occupies a very important position in the planning of the urban green space system.

Because even if a city's green space index meets the requirements, if its layout is unreasonable, then it is difficult to meet the requirements of urban ecology and the requirements of citizens' leisure and entertainment.

On the contrary, if the total amount of green space in a city is not only appropriate, but also the layout is reasonable, it can be closely integrated with the overall planning of the city, and a perfect green space system can be truly formed.

Then the city's green space system will play an irreplaceable and important role in the construction and maintenance of urban ecology, as well as creating a good living environment for citizens and promoting the sustainable development of the city.

Guide the planning and design of all types of public green spaces in the city, and the specific content is not just a few words that can explain the purchase of relevant books.

1.Urban landscape green space is a component of the urban natural environment, and the urban green space system is also the local system of the urban ecosystem. Through the systematic planning and layout of green space, the integration and coexistence of people, cities and nature are promoted, so as to optimize the survival and development environment of urban society, improve the function of urban operation, protect the diversity of regional organisms, and maintain and guarantee the benign operation of urban ecological mechanism, so as to enhance the natural performance and sustainable development performance of the city.

2.The planning and layout of urban green space should build an urban-rural integration, connect the associated environment of the region, carry out the reasonable distribution of various functional green spaces, and provide a place for various urban life activities. At the same time, through the organization of green space and other functional areas of the city, the integrated function and environmental effect are played.

3.The planning and layout of urban green space should implement the principle of people-oriented, and consider the function of green space to meet the needs of different groups of people. At the same time, the distribution of green land should take into account the principles of sharing, balance and proximity.

4.The planning form of urban green space should be combined with the analysis of the natural conditions of urban land, and the distribution of various functional green spaces should be adapted to local conditions, and the determination of urban green space indicators should be combined with the urban land use conditions to make reasonable and effective use of urban land resources.

5.The planning and layout of urban green space should be used as the basic material, construction and means of urban landscape environment construction, and the natural foundation of the city's landscape, forests and trees should be used to create an aesthetically pleasing urban landscape and strengthen the personality of the urban space environment through the organic combination of greening, architecture and natural geographical features. At the same time, it is necessary to combine the historical and cultural traditions of the city, enrich and reflect the cultural connotation of the urban landscape, and improve the cultural taste of the city.

1. Park green space: open to the public, with recreation as the main function, and has the functions of ecology, beautification, and disaster prevention.

2. Production green space: provide nurseries, flower beds, grass beds and other nurseries for the greening of the county.

3. Prevent the green space from protecting this cluster: the green space with hygiene, isolation and safety protection functions in the county. Including sanitary isolation belts, road protection green spaces, county high-voltage corridors, green belts, windbreaks, county group isolation belts, etc.

4. Attached green space: Attached green land in various types of land other than green space in the county construction land. It includes residential land, public facility land, industrial land, storage land, external transportation land, road square land, municipal facilities land and green space in special land.

5. Other green spaces: green spaces that have a direct impact on the quality of the county's ecological environment, residents' leisure life, county landscape and biodiversity conservation. Including scenic spots, water source protection areas, country parks, forest parks, nature reserves, scenic woodlands, county green isolation belts, wild animals and plants, wetlands, landfills to restore green space, etc.
