Abstract
The invention provides a short-term aeolian and aqueous sediment collecting device and a collecting method thereof, relating to a collecting device and a collecting method thereof. The invention solves the problems that geographic environmental study is difficult and development of the geographic environmental study is obstructed as present chloridion catching and collecting device can not collect the aeolian and aqueous sediments in parts, and is not convenient to operate. The collecting device comprises a collecting plate and a fixed link, wherein the center of the collecting plate is connected with the upper end of the fixed link, and the upper surface of the collecting plate is provided with a plurality of grooves. When the collecting device is in use, firstly the lower end of the fixed link is inserted into soil or bottom sediment requiring sediment capture, the collecting plate is parallel to and appressed with the surface of the soil or bottom sediment, and then the aeolian and aqueous sediments captured on the collecting plate are collected regularly, so as to calculate flux and analyze physicochemical property. The invention is used for collecting short-term aeolian and aqueous sediments.
Description
Technical field
The present invention relates to a kind of harvester and acquisition method thereof, be specifically related to that a kind of short-term is eolian, aqueous deposit matter collection device and acquisition method thereof.
Background technology
The deposition process of research river, lake and wetland can be understood the bulk information of environmental change, and eolian, hydatogen sediment sample collecting is the key of research deposition process, eolian, the aqueous deposit sample of long history; Can accomplish through the method for gathering the sedimentary column core,, aqueous deposit sample collecting eolian for short-term, the sediment harvester that uses in the past research is generally processed by metal material; Mostly be column type or funnel type; Make complicacy, cost is high, and is used for gathering lake sediment more; Sedimental collection has certain limitation for the wetland of seasonal waterflooding; Therefore,, hydatogen sediment sample collecting eolian, present acquisition method and the harvester that does not also have a cover system for short-term.
Based on the above, " equipment environmental engineering " the 2nd volume the 4th phase 42-45 page or leaf discloses one piece of article ' acquisition method is to the influence of chloride rate of sedimentation test result ', (open day on Dec 31st, 2005); The device that adopts in the concrete disclosed hanging slice method in the literary composition is in the wooden frame of north-south suspension in the two-layer gauze clamping; This device suspension is provided with, and can only be used for catching the chlorion of wind, owing on the gauze groove is not set; Therefore, be not suitable for collecting eolian, hydatogen sediment.
Summary of the invention
The present invention can not collect eolian, hydatogen sediment in portioning ground in order to solve existing chlorion seizure harvester; And be inconvenient to use operation; Research brings difficulty to geographical environment; Hindered the problem of geographical environment research and development, so propose that a kind of short-term is eolian, aqueous deposit matter collection device and acquisition method thereof.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: the present invention includes collection plate and fixed bar; The center of said collection plate is connected with the upper end of fixed bar; The present invention also comprises first nut and second nut, and the upper surface of said collection plate is provided with a plurality of grooves, and the center of collection plate has through hole; The upper end of fixed bar is passed second nut, through hole, first nut from the bottom to top successively; First nut and second nut are threaded with the corresponding site of fixed bar, and collection plate is fixed on the upper end of fixed bar, and the angle between fixed bar and the collection plate lower surface is 90 °.Acquisition method of the present invention is to accomplish like this: step 1, the lower end insertion of fixed bar need be caught in sedimental soil or the bed mud; The insertion of fixed bar lower end need be caught 30cm-40cm in sedimental soil or the bed mud, and collection plate is parallel and be close to soil or bed mud surface.Step 2, every eolian, hydatogen sediment of collecting a plurality of groove ITs on the collection plate at a distance from 6 months supply flux to calculate and analysis of physical and chemical property.Step 3, finish using after, fixed bar is taken out from soil or bed mud, after collection plate is cleaned, reusable.
The invention has the beneficial effects as follows: the present invention can collect silt, organic matter, inorganic salts and the organic contaminant etc. of short-term deposition simultaneously continuously; Reduced the influence factor in the collection process; Solved that short-term is eolian, the difficult problem of aqueous deposit sample collecting; This harvester is easy to use fast, acquisition precision is high, and according to inventor's practical operation in the open air, sampling detection limit of the present invention can reach 10
0～10
3G/m
2, clean up after the use, install reusablely, reduced use cost; This acquisition method is simple and practical, and resource consumption is few, cost is low, is applicable to all-environment eolian, hydatogen sediment sample collecting.
