1. Meet the nature and function requirements of green space.

2. To meet the ecological requirements of plants.

3. Reasonable planting density and collocation.

1. Meet the requirements of the nature and function of green space.

Garden plants should first start from the nature and main functions of garden green space. Different garden green spaces have different functions.

The main function of street green space is shading. Vacuum, sound insulation, beautification, etc. Therefore, as street trees, we should choose trees that are easy to live, have low requirements for soil, fertilizer and water, are resistant to pruning, have tall and straight crowns, dense leaves, grow rapidly and have strong resistance to stress. At the same time, we should also consider the organization of traffic and the appearance of the city.

A comprehensive park, starting from its multiple functions, should have a square or lawn for collective activities, shaded trees, gorgeous shrubs, dense forests and sparse forests that need quiet rest;

Hospital gardens should pay attention to the health protection and sound insulation of the surrounding environment, and dense forests can be planted around them. And in the yard near the ward and clinic, plant more flowers and trees for rest and viewing.

The main function of factory greening is protection, and the front area and office of the factory should mainly beautify the environment; The rest green space far away from the workshop is mainly for rest.

2. To meet the ecological requirements of plants.

Choose plant species according to the function and artistic requirements of green space. For example, while meeting the main function of shading, street trees are required to choose tree species with high trunk, easy survival, fast growth, adaptability to urban environment, pruning resistance and smoke resistance. Hedge requires the selection of tree species with dense branches and leaves, which can form a barrier with pruning resistance. The plants planted on the mountain require drought resistance to set off the mountain scenery. Waterfront plants should be moisture-proof and coordinated with waterscape. In the memorial garden, you can plant some tree species that symbolize the memorial object and the tree species that the memorial person likes.

Only when the ecological requirements of plants are met can plants grow normally. On the one hand, the ecological habits of planting plants are basically unified with the ecological conditions of planting areas, on the other hand, suitable ecological conditions are created for the normal growth of plants. The selection of plants should be based on local native plants, excellent exotic plant varieties that have been successfully introduced and domesticated or exotic plants that can meet the required ecological conditions.

3. Reasonable planting density and collocation.

It should be configured reasonably. There should be a reasonable planting density on the plane, so that plants have enough nutrition space and growth space, thus forming a relatively stable group structure. Generally, the distance between planting points should be determined according to the crown width of adult trees. In order to achieve the configuration effect in a short time, the density can also be appropriately increased, and some plants can be gradually removed after several years.

In addition, we should also consider the biological characteristics of plants and pay attention to the reasonable collocation of different types of plants, such as light-loving and shade-tolerant, fast-growing and slow-growing, deep-rooted and shallow-rooted, so as to create a beautiful and stable plant landscape on the basis of meeting the ecological conditions of plants.

(2) artistry

1. The overall artistic layout should be coordinated.

2. Consider the changes of scenery in the four seasons.

3. Fully consider the effects of plant shape, color, taste and sound.

4. Holism, pay attention to the changes of plane and elevation.

1. The overall artistic layout should be coordinated.

Garden green space not only has practical functions, but also can form different landscapes, giving people visual, auditory and olfactory beauty, which belongs to the category of artistic beauty. Therefore, plant configuration should also conform to the law of artistic beauty, and be reasonably matched to maximize the "beauty" charm of garden plants.

Different green spaces, scenic spots and buildings have different properties and functions, so the plant configuration should reflect different styles and handle the relationship between buildings, mountains, water and roads.

For example, parks and scenic spots require beautiful seasons. Flowers, lively and lively, and tree species should be diverse and colorful.

Temples and monuments require solemnity. When allocating tree species, we must pay attention to their size and shade to adapt to the nature and volume of the building.

2. Consider the changes of scenery in the four seasons.

It is necessary to comprehensively consider the differences in time, environment, plant species and their ecological conditions, so that rich plant colors can appear alternately with the changes of seasons. For example, in areas where tourists are concentrated in four seasons, there must be scenery to enjoy in all seasons. The color, fragrance and morphological changes of plants, leaves, flowers and fruits in plant landscape combination are also varied, but it is necessary to make clear the priorities and highlight one aspect from the perspective of function to avoid confusion.

3. Fully consider the effects of plant shape, color, taste and sound.

There are many requirements for people to appreciate the scenery of plants, but there are few all-round garden plants. Therefore, we should give full play to the characteristics of each garden plant. It should be designed according to the characteristics of garden plants themselves.

Bauhinia mainly appreciates its spring flowers.

Fragments of pine trees can form the sound of "pine trees"

4. Holism, pay attention to the changes of plane and elevation.

Garden plant planting design should focus on the whole. Pay attention to the planting density on the plane; In the vertical direction, we should pay attention to the crown line and open up the landscape in the Woods; At the same time, we should pay attention to the landscape level of plants and the ornamental effect from far to near (from a distance, we often look at the overall and large-scale effects; Look carefully at shapes, flowers, fruits, leaves, etc. A tree.

Note that the ceiling line is vertical.

The overall artistic layout should also be coordinated. According to the requirements of the local environment in the general layout, different planting forms are adopted. Regular garden plants are planted in pairs, while natural garden green space adopts asymmetric natural planting, which fully shows the natural posture of plant materials. Such as gates, main roads, plastic squares and large buildings, conventional planting is often used, and natural planting is used near natural landscapes, lawns and asymmetric small buildings.

Natural garden green space adopts asymmetric natural planting.

⑶ Economy

1. Make full use of local tree species

2. Pay attention to economic tree planting

1. Make full use of local tree species

Each region has unique native tree species. If we can make good use of these rich plant resources, there will be a new breakthrough in plant configuration, which is also a way to solve the contradiction between the increase of urban garden green space and the increase of construction cost. Because native tree species have strong adaptability, seedlings are easy to get, and local characteristics can be highlighted.

2. Pay attention to economic tree planting

Planting some economic forest tree species, such as persimmon, ginkgo, loquat, bayberry, hickory, Eucommia ulmoides, etc., can organically combine ornamental and economic benefits.
