Embodiment Construction
[0031] The present invention is described in further detail below in conjunction with examples: said five steps of this method, in a nutshell, step one to three is the basic work before the indirect measurement, and its purpose is to set up functional relational expression, and step four is measured work, both Inseparable. Once the functional relationship is established, it only needs to carry out the actual measurement work in the future. Let's take the chestnut forest measured once a month as an example to introduce this method:
[0032] The indirect measurement of soil greenhouse gas emission rate in chestnut forest is carried out in the following five steps:
[0033] 1. Determination of factors:
[0034] According to the correlation between soil greenhouse gas emissions and soil factors, the four key factors affecting soil greenhouse gas emissions are soil temperature, soil moisture content, soil water-soluble organic carbon content and soil microbial biomass carbon cont...
