Gardens include gardens, homesteads, small gardens, gardens, parks, botanical gardens and zoos. With the development of landscape architecture, it also includes forest parks, squares, streets, scenic spots, nature reserves or national parks and resorts. Gardens are also called gardens, caves, gardens, pavilions, gardens, pools, mountain pools, pools, other businesses, mountain villas and so on. In China's ancient books, they are called gardens, while in the United States and Britain they are called parks and scenic gardens. Although their nature and scale are not exactly the same, they all have a common feature: in a certain area, using and transforming natural landscapes or artificially opening up landscapes, combined with plant planting and architectural layout, form an environment for people to watch, relax and live. The whole process of creating such an environment (including design and construction) is generally called "gardening", and the science of studying how to create such an environment is "gardening". With the development of social economy and culture, the traditional "landscape architecture" has been endowed with more ecological connotations, forming a new landscape design system. Garden architecture conforms to people's aesthetic concept and social science and technology level, and more reflects the local people's yearning for living space at that time. At present, the site selection of gardens is not limited to famous mountains, rivers and houses, but widely built on the roofs of streets, transportation hubs, residential areas, industrial areas and large buildings. The materials used have also expanded from traditional building materials and plants to comprehensive technical means such as water, lighting and sound.
Commonly used landscaping plants are as follows: (1) Choose robust and easy-to-manage native tree species. This depends on the climate and soil conditions in different regions to choose native tree species suitable for local growth. (2) Choose deciduous broad-leaved trees with large crown and dense branches and leaves. In summer, the community has a large area of shade, but it does not block the sun in winter. It can also vacuum and reduce noise and make the air fresh. For example, Fatong, Yiyang, Fengyang and Hongfeng. (3) Choose evergreen trees and flowering shrubs that change with seasons. Such as holly, pine, arhat, rose, azalea, peony, privet, Berberis, boxwood, Sabina vulgaris, Sabina vulgaris, Forsythia suspensa, Spring Festival, rose and so on. (4) Selecting shade-tolerant plants and climbing plants. In the dark part, choose shade-tolerant plants, such as Begonia, Plum Blossom and Podocarpus. Climbing plants include ivy and starwort.
