Description
Technical field
The present invention relates to a kind of chad screening plant and its application methods.
Background technique
The substrate in natural river lake is related with riverbed geological structure, also related with the landforms in basin, vegetation and river
The gradient, than the hydrologic regimes such as drop, precipitation, flow, flow velocity, flood situation influence it is related.The more chad substrates in general mountain river, Plain
Also high concentration of sediment shale at type river high concentration of sediment substrate or river and estuaries fork.Chad substrate river river water is limpid, and The turbulent river crashes its way through, illumination
Sufficient, Oxygen saturation height is habitat necessary to like pipelining fish or certain fish early life histories.River chad substrate
Composition has the different types such as cobblestone, clam son stone, gravel, and different river chad minerals compositions and morphosis are different.
The fish in chad substrate river are lived in, some are using River Sediment as the place of oviposition breeding, also some forages in substrate,
Also some fish keep away enemy or are had a rest in chad, therefore chad substrate is indispensable in many fish vital movements to inhabit ring
Border.
Variety classes and different size fish are in breeding, forage and the demand in the history of life to chad substrate such as migrate
Difference.It produces demersal egg and produces partial size and form and chad layer depth requirement of the Salmons to substrate chad of heavy viscid egg
It is not quite similar.Therefore, it is necessary to carry out accurately measurement classification to the morphosis of River Sediment, and can be more effectively to its function
It is studied and is evaluated.Simultaneously as basin vegetation is cut down, adopts mankind's work such as sand digging stone, offshore farmland reclamation, engineering construction
It is dynamic, cause soil erosion, substrate to destroy, silt or impurity cover river chad substrate, reduce Habitat for Fish, fish life
History cannot be completed, river living aquatic resources and bio-diversity decline.Therefore, River Sediment reparation is also the base of restoration of the ecosystem
This task, the recovery or reconstruction of substrate need to measure original River Sediment confirmation type, or the bottom referring to close river
Matter composition repaired, therefore, chad substrate measuring appliance is essential tool in River Sediment restoration of the ecosystem, fishery, ecology,
There is popularization and application foreground in the research works such as the hydrology, geology and Ecological Restoration Project.
