Detachable device for measuring respiratory rate of bushwood ecological system

Abstract

The invention relates to a detachable device for measuring the respiratory rate of a bushwood ecological system. The device comprises a pedestal, a measuring box, a CO2 gas measuring instrument, a ventilator and a battery; both the CO2 gas measuring instrument and the ventilator are connected with the battery; the pedestal adopts a cylindrical structure with upper and lower open ends; the measuring box adopts a cylindrical structure, the lower end of the measuring box is open and the upper end of the measuring box can be encapsulated through an openable cover plate; the pedestal is arranged on the bushwood in a sleeving way; the lower end of the pedestal is inserted into soil; the upper end of the pedestal is matched with the open end of the measuring box and connected with the open end of the measuring box hermetically and detachably; the ventilator, the CO2 gas measuring instrument and the battery are arranged on the inner side wall of the measuring box. The pedestal is detachably connected with the measuring box, a plurality of pedestals can be manufactured according to requirements, the measuring box is moved through the whole body, the position of the pedestal maintains unchanged, and repeated measurement of multiple sample points can be realized; the CO2 gas measuring instrument and the ventilator are provided, so that edge effect and soil space heterogeneity are reduced, and the respiratory CO2 concentration of the bushwood ecological system can be measured accurately.

Description

technical field [0001] The invention relates to the field of ecosystem monitoring, in particular to a detachable device for measuring the respiration rate of shrub ecosystems. Background technique [0002] With the development of industry and the increase of human activities, CO in the atmosphere 2 The concentration showed a rising trend. Chemical greenhouse gas emissions, vehicle exhaust emissions, forest fire greenhouse gas emissions, and thermal power plant emissions have led to an increase in atmospheric temperature, frequent extreme weather, climate tends to aridity, and the melting of polar ice and snow in recent years. Ecological and environmental issues such as rising. The main ways to reduce atmospheric greenhouse gases include cutting off pollution sources (closing heavily polluting industries and thermal power plants), and developing clean energy (making full use of solar energy, wind energy, etc.). The most critical way is that plants absorb CO in the atmosphe...

AI Technical Summary

Problems solved by technology

The current ideal method for measuring soil respiration is Fourier transform infrared spectroscopy, such as the LI-8100 and LI-6400 devices produced by American Gene Corporation, but this device is inconvenient to carry in desert areas, expensive, and fast in power consumption. Charging, short optical path, and small area of ​​soil respiration chamber lead to low measurement accuracy, and the respiration of soil layer, litter layer and shrub layer cannot be measured at the same time
