In forest, under natural conditions, Tree Blades directly drop to ground after withering and falling, and have then begun to the mistake decomposed
Journey, this medium of air does not produce movement substantially for the influence very little of blade.So it is exactly directly to fill blade to bury a bag method
Enter, be directly placed at place in situ, decomposed.
But our research object is islands and reefs marine site tangleweed, the plant in its environmental condition and forest for growing is deposited
In the difference of essence.Tangleweed is typically distributed across the neritic province domain below subtidal line, more wide in islands and reefs circumferential distribution
General, some regions can also form the sea jungle of sheet.Completely different with land, tangleweed is all day by the shadow of tidewater
Ring, the huge energy that tidewater is contained is applied to islands and reefs bank, is also applied to tangleweed in itself, and spring tide and neap are taken
The seawater of band, its physicochemical property also has larger difference.So, for tangleweed, its external environment be it is more violent, when
Change is carved, its Litter-fall can naturally also be affected.And tangleweed Litter-fall is with the extension of resolving time, its particle diameter
It is less and less, it is easy to lose, it is unfavorable for the collection of sample, it is therefore desirable to which scope control is carried out to it.In existing technology,
It is generally necessary to enter seabed by diver's diving, the mesh bag that will be equipped with marine alga is fixed on bottom, is all needed when so per sub-sampling
Dive under water and win mesh bag.
