Urbanization is an opportunity and challenge for college students majoring in landscape architecture

China is currently in an unprecedented process of urbanization, and the modern Chinese garden profession must face a major problem of realization, put down the burden of small farmer garden thinking, and move towards a broader space. On the basis of the existing professional fields, efforts should be made to play a leading role in the overall planning and design of residential communities, the planning of nature reserves, the overall landscape and ecological planning of urban and rural areas, land planning, urban design, and the planning and design of tourist destinations, so as to become the backbone of maintaining the natural ecological process and the relationship between man and nature in the black market.

Challenges and opportunities for the Chinese landscape architecture.

The demand for landscape architecture in China's real society.

China is currently in a social period in which industrialization and post-industrialization coexist. The urban and environmental problems faced by the Chinese landscape architecture profession can be summarized as follows:

1) The rapid expansion of urban population has seriously threatened the basic living environment of residents.

2) There is an extreme lack of outdoor sports and leisure space, and the physical and mental regeneration process of the majority of workers cannot be satisfied.

3) Land resources are extremely scarce, so it is difficult to improve the environment by significantly expanding the area of green space. Improving the living environment through suburbanization.

China's unprecedented urbanization process has led to a dramatic deterioration of human settlements, in contrast"Shanshui city""Garden City""Eco-city"The kind of thing is particularly desirable, and its slogan is particularly inspiring. At the same time, there is almost no theory of modern Chinese landscape architecture (compared to the many theories of appreciation of classical Chinese gardens), and in this situation, there is a great danger lurking in China's urban landscaping construction activities, that is, blindly looking at the land and constructing it by personal fantasy"Garden"city, and to guide large-scale garden construction activities. The lessons of history are too numerous to mention, and the so-called ones are happening right now"Beautify""Greening"The event was even more ridiculous.

How to establish its own activity space and development direction in the period of unprecedented urban and social change is of far-reaching historical significance to the development of this major.

How to build an ecological garden city.

First, the scientific connotation of ecological garden.

1.Relying on scientific allocation, establish artificial plant communities with reasonable temporal structure, spatial structure and nutritional structure, and provide people with a living environment for a virtuous cycle of ecology.

2.Make full use of green plants, convert solar energy into chemical energy, improve the utilization rate of solar energy and the conversion of biological energy to regulate the microclimate, absorb toxic and harmful gases in the environment, attenuate noise, and regulate the ecological balance.

3.Beautify the landscape, improve the artistic level in the green environment, improve the value of sightseeing, improve the benefits of social welfare, improve the function of health care and recuperation, and provide people with a higher level of culture, recreation, entertainment needs and a green ecological environment for people's survival and development.

2. How to build an ecological garden city.

How to build an ecological garden city is a worthy question. The development of things is a gradual process, only through step by step, little by little practice, continuous summary can be developed, therefore, there can still be a lot of exploration, some may have been done but do not recognize its ecological significance. Combined with the actual situation, we can start from the following aspects:

1.Increase the green coverage rate and increase the amount of green through various measures. The size of the city's ecological benefits is determined by the amount of greenery, which in turn depends on the size of the leaves of garden plants.

Experiments have proved that large trees have the largest amount of greenery, the greatest ecological benefits, and the least investment in management, so it is necessary to plant more large-sized trees or transplant large trees to achieve immediate results.

2.Create an ecological microclimate with garden characteristics. For example, pedestrian passages and communication spaces should create a large square with a shading environment, and the parking lot should be built into a green square (or parking lot), with a large crown of trees as the shade periphery, and grass bricks should be used for the parking lot paving to further reduce heat radiation.

For architecture, ecological architecture should be promoted, especially the three-dimensional greening of the west and south west walls, and more vines should be planted, which will play a greater role in improving the indoor microclimate. Residential area: When designing the family building, bold ideas, such as the design of "flower beds in the sky" between the floors, planting weeping, hanging plants and climbing plants, which can not only improve the climate and environment of the whole building, but also create a unique garden artistic conception.

3.Try to preserve and build water bodies and reduce the area of hardened ground. Water bodies are a natural factor in environmental design, and they not only have an ornamental function, but also reduce noise and improve the microclimate.

In the construction of the environment, the water body and rainwater storage and waterscape creation are combined, and the grass planting bricks are used to infiltrate rainwater in appropriate places, replenish groundwater, control surface runoff, and store rainwater permanently and in a timely manner.

4.Strengthen the construction of urban shelter forests, scenic forests, and economic forests, and expand the greening of the environment outside urban areas. Ecosystems are interconnected, mutually influencing and mutually restrictive.

Therefore, if a city wants to achieve a good ecological environment, it must pay attention to the greening of the urban junction, return farmland to forest, combine the construction of economic forests and shelter forests, and carry out mountain greening with manpower; In the suburban villages, ecological agriculture is advocated, three-dimensional planting, and farmland shelterbelts are protected and developed to form a belt network.
