Description
Technical field
The invention belongs to lake prospecting technique fields, more particularly to a kind of simple, undisturbed Lake Surface Sediments
Sampling apparatus.
Background technique
Lake is the important component of land hydrosphere, is had with atmospheric thermodynamics, biosphere and lithosphere indivisible close
Relationship is the important tie point of earth layers interaction.Lake experienced very long earth history period, continuous heavy
Product process makes the in store abundant and continuous information of deposit, in addition relatively high deposition rate, can provide Lacustrine Strata
The high-resolution of regional environment, weather and typical event continuously records, to become the weight of global climate and Study of Environmental Changes
Want carrier.Therefore, the geologic climate, palaeoenvironmental evolution and development mankind's activity of different time scales are rebuild using Lake Sediments
Changeement is paid more and more attention, to push past global change research due to have positive effect.
Currently, in the market there are many lake sediment sampler, may be roughly divided into two classes: one kind be than it is heavier, take
With it is inconvenient, use when also relatively cumbersome sampler, advantage is adopted deposit undisturbed, can carry out to strict control 0.5 or
1cm spacing successively divides sample；It is another kind of be comparison it is light, it is easy to carry, using simple snapper, the disadvantage is that every time grab 5-10cm a left side
It after coming on the deposit of right thickness, is on the one hand possible to be disturbed, on the other hand can not press between 0.5 or 1cm to strict control
Away from dividing sample；And there is no the lacustrine deposits that one kind can possess the existing lake sediment sampler advantage of above-mentioned two class in the market
Object sample devices.Therefore, it is necessary to develop a kind of simple, undisturbed Lake Surface Sediments sampling apparatus, in order to solve
The above problem.
Summary of the invention
The purpose of the present invention is to provide a kind of simple, undisturbed Lake Surface Sediments sampling apparatuses, by drawing high
