建築行業英語（簡體書）

Symmetrical balance is where there are more or less equally spaced matching elements of the garden design.With a garden equally divided, both sides could share all or part of the same shape, form, plant height, plant groupings, colors, bed shapes, theme, etc.
Asymmetrical balance on the other hand is one of the principles oflandscape design thats a little more complex.While textures, forms, colors, etc.may remain constant to create some unity, shapes and hardscapes may be more random.This form ofbalance often has separate or different themes with each having an equal but different type of attraction.
Color adds the dimension of real life and interest to the landscape.Bright colors like reds, yellows and oranges seem to advance toward you and can actually make an object seem closer to you.Cool colors like greens, blues, and pastels seem to move away from you and can make an object seem farther from you.
Grays, blacks, and whites are considered neutral colors and are best used in the background with bright colors in the foreground.However, to increase depth in a landscape, you can use dark and coarse textured plants in the foreground and use fine textured and light colored plants in the background.
Colors can also be used to direct your attention to a specific area of the garden.A bright display among cooler colors would naturally catch the eye.
Natural Transition can be applied to avoid radical or abrupt changes in your landscape design.Transition is basically gradual change.It can be achieved by the gradual, ascending or descending, arrangement of different elements with varying textures, forms, colors, or sizes.
