In the planning and design of garden waterscape, waterscape has occupied a very important position. It has the inherent characteristics of water and various forms of expression, and is easy to form various relationships with surrounding scenery. The following is an article about landscape water design that I brought to you. Welcome to reading.

Garden water use: 1. Garden water landscape. Such as fountains, waterfalls and ponds. All of them take water as the theme, and water has become an important part of gardens, which has also led to endless poems and paintings. In very warm conditions, ice lanterns and ice sculptures are also a decorative form of water.

2. Improve the environment, adjust the climate and control the noise. Mineral water has a medical function, and negative ions have a cleaning function, which cannot be ignored.

3. Provide domestic water. The most unforgettable thing about domestic water is drinking tea, seven things to open the door, and the last thing is tea. Tea leads to Cha Sheng Lu Yu's evaluation of water in The Book of Tea: "There are mountains and rivers on the top, rivers on the middle and wells on the bottom".

4. Provide water for production. There is a wide range of production water, the most important one is plant irrigation water, followed by aquaculture water, such as fish and mussels. These two contents are closely related to landscape, production and management.

5. Provide sports and entertainment venues. Such as swimming, boating, skating, ship model, etc. For example, leisure hotspots, such as surfing, rafting, water parks and so on.

6. Provide growth conditions for ornamental aquatic animals and plants, and create the necessary environment for biodiversity. Such as the cultivation of various aquatic plants such as lotus, lotus and reed, and the cultivation of swans, mandarin ducks and koi fish.

7. transportation. Larger water surface can be used as a supplement to land transportation, such as yachts and transport boats.

8. Collect and discharge natural rainwater. This function, in a well-designed garden, will save a lot of underground pipeline investment and create good site conditions for plant growth. On the contrary, the backward flow of sewage and the flooding of seedlings will cause unexpected losses.

9. Protection and isolation. Such as moats and isolated rivers, it is the most natural and economical way to isolate space with water surface. Stretching out, the water creates a tortuous route for the garden. Facing each other across the bank is beyond our power.

10. Water for disaster prevention. Fire fighting and drought resistance are inseparable from water. Urban garden water bodies can be used as standby water for fire fighting, while suburban garden water bodies and ditches are drought-resistant natural pipe networks.

The above contents are not comprehensive. Each garden water body has its main function, among which the most important and common is the garden landscape function. The formation of water landscape, engineering design, water quality and quantity requirements and landscape design are discussed as follows. This passage can be used as a reference when designing waterfalls.

Formation of Water Landscape in Gardens (1) Water is liquid at room temperature. There is no fixed shape in itself, and its ornamental effect depends on the shape, water quality and surrounding environment of the water-containing object.

Various shapes and postures of water are related to containers. When the container is designed, the water posture to be achieved comes out. Of course, this is also related to the texture of water itself. Generally speaking. Water should be transparent, colorless and tasteless. Various water bodies have different uses and different requirements for water quality. But the polluted water is not like this, it is the opposite of the landscape. Occasionally there are people who need to see it. Dyeing water is another matter. Natural factors such as wind, temperature and light around the water body will also affect the ornamental effect of the water body. Like a strong wind. When the waves are rough, how can we appreciate the reflection on the water? The temperature dropped, the water turned into ice, and the sparkling lake turned into a smooth and dazzling skating rink. Different interests in watching, the direction of use is also different. The effect of light on waterscape is more obvious, and everyone knows how to appreciate waterscape during the day and at night. Please pay attention. In order to achieve the effect, it is often necessary to supplement artificial lighting in the water body. The viewing effect at this time is often better than the best landscape during the day.

(2) There are two main differences between the containers on which garden water bodies depend:

? Water body in natural state. Such as lakes, ponds and streams in nature, whose slopes and bottoms are naturally formed.

? Water body in artificial state. Such as fountains and swimming pools. , whose sides and bottom are artificial structures.

Although ordinary people can easily distinguish different water bodies and name them, such as fish pond, first spring and colorful music fountain, this is a "commentary". Besides, the above examples are not absolute. The fountain in the city square is artificially built, but the fountain in Geneva 100m is in the lake. How to deal with this "container" in design practice? But it is easy to be confused, and there are often arguments, especially natural gardens. For example, are streams outside high-grade office buildings or rivers in high-rise residential areas reinforced concrete bottoms and barges, or natural slopes and mud bottoms? It will make developers struggle. In the past, some people laid cement slabs on the natural river bottom of the park to prevent people from stepping on mixed water and thinking about swimming pools. Recently, it is an attempt to close the river bottom of a city to control environmental polluters. But they are not very successful, or even counterproductive.

(3) When constructing artificial water environment, the following situations deserve special attention.

Design elevation of water body

When the design elevation of the water body is much higher than the local natural constant water level elevation, and the soil there is loose (sandy soil) and it is difficult to store water, then a waterproof layer must be built to keep the water body at a relatively stable elevation and meet the requirements of landscape design. For example, the high pool in the newly-built Hongqiao Garden in Shanghai. The low pool naturally bottoms out.

The design of water bodies has high requirements for water quality, such as swimming pools and playing pools. Water quality must be maintained by filtration and circulation, or water bodies must be replaced regularly. At this time, a waterproof layer must be built to isolate it from the outside world. Most music fountains, swimming pools and water worlds are like this.

External environment of water body

If there are underground structures such as underground garages, shopping malls and complex pipe networks near the water body, and sometimes even the water body is just above the basement, an artificial waterproof layer must be designed to reduce the adverse effects of water body leakage on underground structures. This is a common situation in city squares at present. Natural rivers and streams in this situation should be artificial waterproof layers.

Secondly, there are buildings, roads, dense crowds around the water body, or the soil is poor, so it is impossible to form a stable natural river slope, especially the river slope with large water surface and aiming at the dominant wind direction. At this time, artificial revetment must be built around the water body to prevent collapse and ensure safety. This is the case with many water bodies in Shanghai cities and gardens. However, whether the river bottom is natural or artificial depends on the requirements of the above two points, and cannot be generalized just because of refutation. Shanghai is a water network area, but most rivers are natural bottoms, which should be noted.

Judging from the above three requirements, the first is to emphasize the "quantity" of water. Maintaining the design elevation is actually maintaining the water quantity, which is not affected by the fluctuation of natural water level. The second is to emphasize the "quality" of water. Therefore, at this time, the water body in the artificial environment must have certain area and capacity restrictions to control the project cost and maintenance cost. I think an artificial landscape water body reaching several thousand square meters is already very large; If it reaches tens of thousands of square meters, it can actually be called a "lake". Why not let it appear in a natural way? The third is to emphasize local conditions and look at the surrounding environment according to the main functions of water bodies.
