Abstract

The invention provides a greenhouse gas discharging and collection device for soil at different depths. The device comprises more than two gas collectors with different lengths of circular gas storage tubes. The device is simple in structure, convenient to use and suitable for collecting greenhouse gas at different depths of soil with non-saturated water and soil with saturated water in a non-growth season and can continuously collect gas such as CO2, N2O and CH4; when the gas is collected, the environment interference is small, so that the influence factor in a gas collection process is reduced; the device is easy to operate; the collected greenhouse gas has representativeness in discharging intensity in a unit area; and the device can continuously observe discharging of the greenhouse gas of the soil for many years and can observe the accumulation situation of the greenhouse gas in a freezing process and the discharging situation in a soil melting process. The device can be widely applied to observation and research on discharging of the greenhouse gas of various types of soil at different depths in a farmland, a grassland, a wet land and the like.

Description

technical field [0001] The invention relates to a greenhouse gas collection device and an in-situ observation method for soils at different depths. Background technique [0002] Global environmental change, especially climate warming, has attracted worldwide attention. CO 2 、CH 4 and N 2 O is the main greenhouse gas, CO in the atmosphere 2 、CH 4 and N 2 O In addition to emissions from human activities, terrestrial ecosystems are also important sources of emissions. The monitoring of greenhouse gas emissions is mainly concentrated in the growing season of plants, and the static chamber method is often used to collect greenhouse gases. The collected gases are the release of vegetation and surface gases. This method of collecting gases does not distinguish the production and emission characteristics of greenhouse gases at different depths in the soil. Therefore, developing a set of devices and collection methods suitable for greenhouse gas collection at different soil d...
