Therefore, landscape architecture is shaping, promoting and adjusting elements of our environment, including buildings, bridges and roads, as well as trees and rivers. Reflected in different scales, not only backyard and garden, but also watershed and regional scale. For me, there are many kinds of landscapes, including natural landscapes, agricultural landscapes, suburban landscapes and urban landscapes. In fact, the city is a very urbanized landscape form. Although there are buildings everywhere, it is still a landscape. It has topography and dynamics, like a forest, in which things come and go, from zero to total. So one of the characteristics of landscape is that no one can control or design everything in it. If you are interested in landscape design, you must learn to cooperate with others, other fields and other disciplines to get people to help you. Then you need to deal with the relationship between different elements, not just creating and shaping space. Of course, we did design and shape some objects and some places in the landscape, but the complete landscape is beyond our power, control and guidance. This explanation is a bit circuitous. Let me sum it up briefly: parks are landscapes, cities are landscapes and gardens are landscapes.
Speaking of nature, the meaning of nature is that we are a part of it. Nature doesn't necessarily need us, but we need nature, because we are creatures of nature. The problems of many cities, such as why we have parks and why we are worried about the design and organization of cities, are because these cities are likely to be very bad environments for us. They will do harm to people, not only in terms of public safety, but also in terms of the impact on residents' health. We need sunshine, we need fresh air, we need exercise, we need to be able to adjust the focal length of our eyes-we need the stimulation of the natural world, because we come from the natural world and are still in it, even if we don't realize it. Now I am in nature, and the laws of thermodynamics and physics are acting on this room and me. This is exactly what the sages of the East and the West have realized: we are a part of a grand and flowing force and energy, no different from other animals and plants.
