Internal lake external sea type mangrove forest hydrophilic city

Abstract

The invention provides an internal lake external sea type mangrove forest hydrophilic city. The city is characterized in that a city main body is constructed along a river channel, mangrove forests are grown on the two sides of the river channel, breakwaters are built between the outer sides of the mangrove forests and the river bank of the river channel correspondingly, the height of the breakwaters is higher than the water surface when the river channel is in a high water state, landscape belts are designed on the two sides of the river channel penetrating through the city main body, the landscape belts comprise inner lakes which are arranged along the river channel, the inner lakes are built between the breakwaters and river banks, the inner lakes communicate with a rainwater drainage system of the city main body, the water level of the inner lakes are lower than the water level when the river channel is in the high water state, first-stage water gates are designed on the breakwaters, and the inner lakes communicate with the river channel through one-stage control. The mangrove forests can play a role as protective forests, so that the invasion of the sea tide to the breakwatersis greatly reduced, due to the design of the breakwaters, the influence of rising and falling of the sea tide on the water level of the inner lakes is relatively small, the design of the landscape belts is facilitated, and sightseeing of people is facilitated.

Description

technical field [0001] The invention relates to the field of urban planning, in particular to a mangrove hydrophilic city with inner lakes and outer seas. Background technique [0002] Mangrove refers to the tidal flat wetland woody biome composed of evergreen shrubs or trees that grow in the upper part of the tropical and subtropical low-energy coastal intertidal zone and are flooded by periodic tides. Mangroves grow in tidal flats and shoals at the junction of the land and the ocean, and are a special ecosystem where the land transitions to the ocean. Mangroves have a well-developed root system, which can greatly reduce the power of waves. Mangroves are natural green and environmentally friendly forests that reduce waves and build coastal protection. At the same time, the mangroves are exposed to the sea surface at the upper part of the high tide, and can form a green plant belt along the coast on the sea surface, which has high ornamental value. However, mangroves usual...

AI Technical Summary

Problems solved by technology

However, mangroves usually grow in relatively muddy land, making it difficult for people to observe mangroves up close.

Mangroves usually live on the coast near rivers, and have high requirements for water salinity and water quality. The ecological value of mangroves is outstanding, but the shoal environment where they grow is relatively fragile and easily affected by the surrounding environment.

Especially in the development and construction activities of traditional coastal cities, mangroves often suffer great damage, which also reduces the anti-wave capability of coastal cities and makes the disasters caused by strong winds and waves more serious.
