Description
Technical field
The present invention relates to soil sampling technical fields, more particularly to a kind of surface layer ecological recovery sampling unit for multiple times.
Background technique
Ecological recovery refers to the process of that help restores and manage ecological integrality, ecological integrality include bio-diversity,
The critical range of ecological process and structure, region and historical relation and the variability of sustainable culture practice.Ecological recovery is
Human interference is stopped to the ecosystem, with the pressure that lightens the load, by the capacity of self-regulation and self organization ability of the ecosystem
So that it is developed to orderly direction, or using the self-recovery ability of the ecosystem, be aided with artificial measures, makes by broken
The bad ecosystem gradually restores or develops the ecosystem to benign cycle direction.
The basic steps of upper soll layer ecological recovery research are then the collecting work of pedotheque, however since soil is one
A inhomogenous group, there is difference between each individual, to obtain representational sample, in acquisition, it is necessary to follow " with
Machine ", " equivalent ", the principle of " anti-pollution ".Currently, columnar soil sampler is filled using relatively broad a kind of soil collection
It sets.Well known columnar soil sampler mainly includes two kinds of complete column cylinder and integral type semicircle drilling.On acquisition mode
It is divided into artificial acquisition and mechanical acquisition again, the shortcomings that machinery acquisition is that use condition is harsh, complicated for operation, is easy sample dirt
Dye.The columnar sampler of manual mode is usually to be driven using rotatable handle or use tension weight churning come so that sampler is vertically inserted
Enter into soil, and then pedotheque enters in sampling head, then soil sample collector is directly enhanced or led to from soil
It crosses and rotates backward handle taking-up sample head, finally release sample from sampling head.Sample cannot when taking out sample from sampling head
Molding is easily lost, and sample transfer process is cumbersome, it is difficult to determine the principle of " equivalent ".
Therefore, a kind of dedicated sampling unit for multiple times is designed very must to be acquired surface layer ecological recovery pedotheque
It wants.
