Knew floating island ecosystem

actually “floating island” the concept, comes from the waters “Lu Yuhua” the phenomenon.In nature, many originally Lu Sheng plant, so long as has the good support, also may grow in the water.Therefore in natural lake or in pond land territory process, part long on land plant, can spread gradually grows to the water surface on, a lot of year gets down, on the water surface can form the thick land territory vegetable layer, is called “the floating island” or “the grass island”

slowly artificial floating island？

Artificial Floating Islands is made ​​artificially constructed floating island, the earliest applications of artificial floating island is a masterpiece by those who love birds. In 1970, the United States Crawford (Gurney I. Crawford) in order to allow Canada goose habitat and breeding grounds, the use of wood, wooden, twigs, leaves and straw and other materials to build the first artificial floating island. Artificial floating island has a wastewater treatment effect on the floating island that can be transparent oxygen plant roots can provide microbial attachment growth characteristics, not only can purify water, but also beautify the landscape, provide food and habitat for wildlife where utilization. Artificial floating island is also often associated with surface flow constructed wetland use each other to increase the effectiveness of decontamination.

Taiwan's artificial floating island

Taiwan 's most famous natural floating islands located in Yilan Shuanglianpi . " Artificial floating island " of Taiwan origin , it is Thao live in Sun Moon Lake area , they made ​​water floating bamboo frame , covered with grass blankets, rice, become a " floating fields ." Such ingenuity become assets of Taiwan's traditional labor law , and gradually widely used in the country, such as residents of Chiayi Kandelia planted with wooden frame , on the sea , it would be able to cut the structure of the wave ; Shoufeng Township Hualien Hakka ancestors , but also surrounded by a triangle of bamboo species on aquatic plants to purify water, landscaping .

Functional artificial floating island

Artificial floating island which functions?

◎Ecological function - Since artificial floating island has a shelter, vortex , fodder and other effects , providing birds and fish and other biological habitat , fish growth and the formation of space ; may also attract birds nesting above the floating island . Research indicates observe new artificial floating island , biological entering the order , there is a plant after attracting flying ability of insects ( butterflies, dragonflies, beetles , etc. ) and predatory insects, spiders stationed ; then attract amphibians and aquatic life , the way to the food chain floating islands form a rich ecosystem .

 

◎production function - providing fish to escape the floating island ecology and growth space , aquatic plant roots and can filter and purify water , with production of crops and aquaculture economic function .

 

◎landscape features - now majority of artificial waters , in order to prevent erosion waterfront mostly using cement construction , and is not suitable for plant growth , ecological floating island settings can improve the landscape style waters. Floating island above choices such as planting plants lure butterflies , you can create a unique landscape of water plants , green landscape landscaping with water features .

 

◎revetment function - with clipping effect , protecting waterside embankment

   

◎water features - mainly for water eutrophication , absorb water, nitrogen , phosphorus and other elements through the roots of plants , to water purification effect.

   

artificial floating island ecology principles of water purification is the use of aquatic plants, animals, insects and microorganisms in natural water environments absorption, ingestion , digestion, decomposition and a series of biological , chemical functions , to achieve ecological management eutrophic water bodies. Namely: the special light biological carrier according to different design requirements, stitching, combinations, built into the required size or geometry , into the damaged water , will go through screening, domesticated absorb organic pollutants in water , more powerful aquatic ( terrestrial ) plants grown implanted prefabricated floating carrier vessel , the plant was grown in soilless cultivation under similar circumstances , a natural extension and plant roots suspended in water , adsorption, absorption of water, ammonia , nitrogen, phosphorus and other organic pollutants , as a body of water fish, insects and micro-organisms survive and conditions attached to the offer , while the release of compounds that inhibit the growth of algae . Under the joint action of plants , animals, insects and microorganisms to purify the water quality of the environment , to repair and rebuild aquatic ecosystem purposes. Is a function of both sewage treatment , water garden and landscape effects both versatile and practical eco facilities , therefore , in the current environment of sewage treatment and water garden projects in the ascendant , has a broad application space and development prospects.
