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 [0001] The invention relates to a collection device and a collection method thereof, in particular to a short-term aeolian and water sediment collection device and a collection method thereof. Background technique [0002] Studying the sedimentary process of rivers, lakes and wetlands can provide a lot of information about environmental changes. The collection of eolian and aquatic sediment samples is the key to studying the depositional process. Long-term historical eolian and aquatic sediment samples can be obtained by collecting For the collection of short-term eolian and hydrogenetic sediment samples, the sediment collection devices used in past studies are generally made of metal materials, mostly cylindrical or funnel-shaped, complicated to manufacture, high in cost, and multi-purpose. For the collection of lake sediments, the collection of seasonally flooded wetland sediments has certain limitations. Therefore, for the collection of short-term eolian a...
