Field warming test device suitable for tidal salt marsh wetland

Abstract

The invention belongs to the technical field of greenhouse gas research of tidal salt marsh wetlands under the background of global warming, and particularly relates to a field warming test device suitable for a tidal salt marsh wetland. The field warming test device comprises an open-top box, a bottom support fixing member and fixing rods, wherein the bottom support fixing member is inserted intothe soil layer of the tidal salt marsh wetland, and the upper end of the bottom support fixing member is higher than the upper surface of the soil layer of the tidal salt marsh wetland; the open-topbox is arranged on the bottom support fixing member, and is connected to the bottom support fixing member through a plurality of fixing rods that are distributed in the circumferential direction. Thefixing rods are vertically arranged, hooks are arranged on the upper ends of the fixing rods, the hooks are hooked at the top of the open-top box, and the lower ends of the fixing rods are inserted into the soil layer of the tidal salt marsh wetland. The complete set of test device disclosed by the invention is low in cost, simple in structure and easy to assemble, and is suitable for field warming control experiments of the tidal salt marsh wetland.

Description

technical field [0001] The invention belongs to the technical field of tidal salt marsh wetland greenhouse gas research under the background of global warming, and in particular relates to a field warming test device suitable for tidal salt marsh wetland. Background technique [0002] Tidal salt marsh wetlands rely on higher primary productivity, faster carbon accumulation rate, slower organic matter decomposition rate and lower CH 4 Emissions become an important part of the global "blue carbon sink" and play an important role in addressing climate change. Currently, with global atmospheric CO 2 As the concentration increases, global warming has become an unchangeable fact. Studies have shown that by the end of this century, the average global surface temperature has increased by about 1.5-2.0°C. In the context of global warming, the carbon sink function of tidal salt marshes will also be greatly affected. Therefore, the ecology community is very concerned about the green...

Problems solved by technology

However, the traditional field warming test device is difficult to apply to the special ecosystem of tidal salt marsh wetland

First of all, the fluctuation of the tide will bring huge momentum, which can easily cause damage to the test device

Secondly, the soil in tidal salt marsh wetlands is often in a muddy state, making it difficult to install complex test devices
