Seagrass beds are relatively fragile ecosystems with high requirements for external conditions and are easily affected by the external environment. Human activities such as reclamation, port construction, sand dredging and destructive fishing can seriously endanger the survival of seagrasses. However, seagrass plays a very important role in the coastal ecosystem. The distribution of seagrass beds is less than 0.2% of the total ocean area, but the carbon sequestration amount reaches more than twice that of forests, which is an important global carbon pool. Organic carbon storage in seagrass beds accounts for about 10% of the total annual organic carbon buried in the global ocean, and has an important function in site microclimate regulation.

Just one acre of seagrass supports more than 1 million species of marine life. It is a habitat that many species in the ocean rely on for activities such as reproduction, baiting and sheltering, and an important habitat and nursery for many marine animals. The safe rearing of the next generation is critical to species survival. Once seagrasses are gone, the marine life that calls them home naturally cannot continue to survive and may even

The practical applicability of seagrass materials is further promoted by using seagrass building materials to renovate houses around the site. Seagrass building materials are air-dried seagrass stuffed into mesh bags and fixed to the wooden structure walls and roof of the house. More seagrass is also enclosed in wooden boxes and used as insulation behind the façade and under the floor. Experimental piloting of surrounding houses is used to appeal to the certainty of implementability of seagrass building materials and to raise human awareness of the destruction of the natural environment. The use of seagrass guardian materials is a sustainable approach to building development, and in a broader sense a practical exercise in CO2 reduction, environmental protection and sustainability.

Waters

The Bei River is located in South China and is the second largest water system in the Pearl River Basin. In the middle reaches from Shaoguan to Mangzai Gorge, the valley is wide and sandbars, river banks, alluvial plains or basins appear one after another along the river. The banks of the main stream between Mangzai Gorge and Feilai Gorge are low mountainous and hilly areas. The site is selected for the middle and upper reaches of the Bei River flowing through Yingde city. It is important in the whole section of the River as it carries the upper and lower parts.

As a county-level city under Qingyuan City in Guangdong Province, Yingde is a latecomer in the large economic province. For thousands of years, Yingde, however, has been silently bearing the greatest pressure during the flood season, becoming the last line of defense before Guangzhou and Foshan.

Status Of The Site

Each flood causes the soil to sludge, which seriously affects the growth of plants and crops. There is a loss to the ecological environment, food production and economy.

The city-side levee is 8.5 meters, which effectively blocks the flooding to the city center. But the east of the river will be completely submerged by the flood.

The Yingde People's Bridge has been abandoned due to flooding combined with age and dilapidation. It cannot be used for traffic and pedestrians, and the

The soil is compacted and the plant withers

When the flood comes, crops and villages are submerged

In villages close to the river, the June 2022 flood inundated nearly two stories high and one story high farther from the river. The annual floods have caused varying degrees of inundation of the riverbank park, and the 2022 flood caused the entire park to be inundated. Although the riverbank was erected with a government ban sign, locals still farmed the area.

Wetland Park Embankment

When there is no flooding, the embankment space serves as an entrance for the whole park to provide residents to gather and rest here. The Flood Prevention & Relief Center also provide recreation and education programs for residents.The park provides people with functions such as viewing, leisure, recreation and cultural exchange. Water-friendly platforms, walkways, natural vegetation, etc. are arranged in this space, thus creating a rich landscape.The wetland space is designed to plant water-resistant plants and build water-friendly wooden walkways to create reed waterways and other scenes, creating a natural wetland landscape with southern characteristics. It is also suitable for the survival of birds and aquatic plants and animals in the area to increase biodiversity.

The urban waterfront park provides a water-friendly environment for residents and visitors, and is a public touring place for the city. The design fully integrates the current height difference of the site and divides the site into three areas through the height difference: embankment space, park space and wetland space. When a flood comes, three different spaces resist different volumes of water. The Flood Prevention & Relief Center helps residents affected by the flood. The design sets back the original riverbank to increase the capacity of the wetland. Vegetated levee is used to minimize the damage to plants and soil after the flood.

Building Functional Zoning

The Flood Prevention & Relief Center is divided into three floors and is a multifunctional service place. The first floor is mainly used as a catering and reception center, while the space for material storage is divided.The second floor is for education and flood detection.

During the field survey, we found that the residents of Yingde City are not fully aware of the causes of floods and the measures to deal with them. We hope to use the education space to inform the, of the specific hazards of floods to animals, plants and humans, and to help them understand the history of floods in the area. The flood monitoring space is established near the river, so that professionals can monitor the floods as soon as possible and give feedback to the residents.The third floor serves as a viewing platform and sitting area with a distant view of the city of Yingde on the other side of the river.

Population Density

Global warming is caused by a variety of factors, both human and natural. Human factors include the sharp decline in forest resources, the atmosphere, pollution from toxic waste, and the reduction of biodiversity. And natural ones include the frequent global volcanic eruptions and the cyclical rotation of the Earth’s orbital path. Passive architecture is a new concept of energy efficiency, developed on the basis of low-energy architecture. It refers to the use of materials with high thermal insulation properties, doors and windows with low heat transfer coefficients and an optimised construction to achieve efficient thermal insulation and a comfortable building temperature. The design is inspired by passive architecture. It is hoped to make the interior a suitable place for people to move around and rest without adding any artificial temperature control facilities.

A commercial complex consisting of an outdoor plaza and an indoor shopping mall. By placing the building here, it will reduce the impact of the heat on the people who come to play and walk in the area.

Temperature Analysis

The highest global temperature ever recorded was 57.8°C. On 13 September 1922, in the El Azizia region of Libya, Africa, the local temperature reached 57.8°C. Besides, the high temperatures will bring intense droughts, continued sea level rise in coastal areas, permanent permafrost melting, ocean acidification and a series of other effects.

Master Plan

The direct sunlight on an open square or open space rapidly accelerates the ground temperature and raises the body temperature. In this situation, the building allows people to enjoy the surrounding landscape and feel physically comfortable at the same time.

Three planting ponds have been designed at different locations in the building and the different plants give the site various planting landscape throughout the year, especially in summer. The gas of the greenhouse effect is carbon dioxide, which is absorbed by the green plants. By releasing oxygen, the indoor temperature can be lowered. With the insulating building materials, the whole building becomes a shady place in the hot summer.

Rock wool board

It is made from rock wool and synthetic resin. Due to its low thermal conductivity, it effectively reduces indoor temperatures. It also absorbs internal echoes, isolates external noise and has a near-zero formaldehyde content. It is particularly suitable for places where health, quietness, cooling and insulation functions are required.

Heat reflective glass

The surface is coated with films of metals, non-metals and their oxides, producing a 20-40% reflection of solar energy while maintaining good light transmission. Heat-reflective glass also has a one-way transmission effect, increasing the privacy of the building.

Reinforced concrete columns

Its main materials are sand, stone and cement, with a relatively small proportion of steel. The durability of the structure is ensured by its very good durability and long service life, as well as by the fact that it does not corrode.

Manila grass

The grass is light and shade tolerant, warm and moist, with a high degree of cold and drought tolerance, and flourishes in spring and autumn. The rhizomes reproduce well, the grass regenerate well and are more resistant to trampling.

Floor-bearing concrete floors

The structure greatly increases the resistance of the concrete to weathering and UV erosion thus extending the use of the concrete floor.

The greenhouse gas concentration hits a new global high in 2020. Data from specific locations show that it is continuing to increase in 2022. Plants, on the other hand, can fix free CO2 gas in the air through photosynthesis and release oxygen. Plants also have a sorption effect on airborne particulate matter (dust), including PM2.5. The building is mainly insulated from heat radiation by vegetation and insulation materials, trying to achieve a temperature and humidity suitable for human activity without any other cooling facilities. After stabilising the vegetation in planting ponds 1, 2 and 3, climbing plants such as climbers, grapes, petunias and wisteria will be planted around the building. They climb along the walls or supports to form a green ‘cool canopy’, which protects the building from the direct sun, absorbs dust and beautifies the environment. The reasonable distribution of climbing plants changes the microclimate of the living room, and as vegetation, it separates the direct radiation from the sun and releases some of the water.
