Reducing water pollution
降低水質污染
The mangrove species makes use of their root system to absorb inorganic substances from the water,
紅樹品種藉著它們的根系吸收水中的無機物,
reducing water pollution,
降低水質污染,
for example by the metabolism of microorganisms, soil adsorption, chemical settlement and the plant's own absorption and so on.
例如微生物的代謝作用、泥土表面吸收、化學性沈澱和由植物吸收等.
This method may decrease the amount of particulate matter, chemical oxygen demand, nitrogen, phosphorus and other elements or metals in water.
這種方法可以降低水中的懸浮物、化學需氧量、氮磷等元素和金屬等。

Reducing water pollution
The mangrove species makes use of their root system to absorb inorganic substances from the water, and reducing water pollution in the process, for example by the metabolism of microorganisms, soil adsorption, chemical settlement and the plant’s own absorption and so on. This method may decrease the amount of particulate matter, chemical oxygen demand, nitrogen, phosphorus and other elements or metals in water.
Protecting the coast line
Mangrove forests can stabilize the waterfront of the river mouth and the riverbank, and even protect the coastline from corrosion by ocean waves.
Preventing flooding
Mangrove forests can stabilize the moisture underground and on the soil surface, and is helpful in stabilizing and storing water sources, thus preventing overflowing. In recent years, the lowland area in the New Territories was often affected by flooding caused by rainstorms, the primary cause being the engineering developers changed the wetland’s land use.
Mangrove forests and fishery
The mangrove forest is very important to the maintenance of the coastal and near-shore fishery output, as they not only provide nutrients for the seacoast ecosystem, but also an appropriate habitat for fish, shrimps, crabs and other aquatic organisms.
Scenic value
Mangrove forests have excellent surroundings—they gave wild organisms a habitat and hunting grounds, human beings a place for economic activity (for example fishery and agriculture) or an outdoor mobile classroom, eco-tourism a scenic route for traveling, and lastly, the society a source of economic income.
