The role of garden plants in the creation of landscape design space

(A) adjust the microclimate and purify the space

Strengthening the planting of urban and garden plants can not only adjust the climate of cities or regions, but also purify the space. The construction of cities and gardens in China will combine artificial architecture and natural environment at the same time, but as we all know, no matter how ingenious the artificial architecture design is, it can't replace the aesthetic feeling brought by natural landscape. Artificial buildings often have too many carving marks, lack natural flavor, can not be well integrated into the surrounding landscape, and it is too monotonous to watch for a long time. The cultivation and growth of plants are more diverse, and various characteristics will be developed in the process of growth, which is the unique charm of natural landscape and biology. Therefore, in urban design, plants will become the main design object, which can not only reflect the display and integration of plants to space, but also improve urban environmental problems and adjust urban regional climate by planting plants, thus playing a role in purifying space.

(B) Organization and guidance space

Various plant elements constitute a changeable sense of urban space. The use of space by plants is not simply building and stacking, but constructing space through the organization of various elements, thus guiding the spatial hierarchy and finally producing a harmonious aesthetic feeling. Therefore, whether from the natural point of view or from the artificial point of view, the collocation of plant species and the location of activities can play the role of organizing and guiding the space, creating rich aesthetic feelings for the people watching. Using different kinds of plant design to create different sense of urban space, combining various elements into a whole, not only avoids the sense of organizational suddenness, but also produces a comfortable and harmonious aesthetic feeling.

(C) color and fragrance to beautify the surrounding environment

With the improvement of modern garden design, people are developing the function of plants to create a sense of space more and more comprehensively, so they also put forward higher requirements for plant design, which not only requires plants to be used as materials for urban beautification to purify the urban environment, but also develops the colors and smells of plants, so as to beautify the surrounding environment of the city through the collocation of colors and smells. Designers reflect the natural elegance of different plants and skillfully show the sense of space of plants through the diversity of plants and the integration of colorimetry. In many people's impression, more complex lines can show exquisite technology, but in fact, they are simpler and more aesthetic. Simple shapes, colors and lines are more appealing than complex designs. Repetition is the most commonly used method to embody concise and clear style in plant landscape space, which is generally reflected by people's most intuitive sense of touch and vision such as color, texture and modeling of plants. In addition, different plants can be repeated in color, texture and shape, so that the whole plant space can be unified, so that repetition does not appear monotonous. Using more repetition in the covered plant space and vertical plant space is the repetition of plants that are completely consistent with various characteristics. This repetitive landscape is very simple, there is not much change, and it will not make people feel bored for too long. The repetition of some changes is the repetition of plant communities, or each group of plants in adjacent groups has the same technology. To achieve the overall unity, it is necessary to ensure that at least one of the characteristics such as color, shape, texture and morphology of repeated plants is changed. This repetition can link the space between groups, thus achieving a unified effect. In short, the repetition of plant morphology will give people a sense of visual comfort and intimacy.
