1 Scope
This standard specifies the indicators of long-term observation of forest ecosystems, including forest hydrology, forest soil elements, forest meteorological
Vegetation climatic gradient elements, Micrometeorological carbon flux, Atmospheric deposition, Forest regulation and control of ambient air quality, Forest community characteristics, Forest
Forest animal resources, bamboo forest ecosystem and other 11 kinds of observation indicators.
This standard applies to long-range observation and research of forest ecosystems nationwide.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1 Soil organic carbon component
Soil organic carbon content of different types.
2.2 Trunk stem flow amountofstemflow
Canopy interception of rainfall after the leaves were transferred to the branches, and then transferred from the branches to the trunk and flow to the forest ground rainfall.
2.3 Penetrate the water throughfal
The difference between atmospheric precipitation and canopy interception, stem flow.
2.4 Runoff
The hydraulic cylinder is directly connected with the cargo box and simultaneously drives the simple elevator which runs the cargo box.
2.5 Forest evapotranspiration
The sum of forest vegetation transpiration and forest canopy evaporation. Vegetation transpiration is divided into single-tree trunk flow, single-stand evapotranspiration and
Multiple stand evapotranspiration.
2.6 Leaf area index
The ratio of total plant leaf area to land area per unit area of land.
2.7 Soil respiration
Soil and the outside world for gas exchange, and soil carbon dioxide into the atmosphere of the process.
2.8 Water vapor flux H2Oflux
Evaporation fluxes on the ground or water surface, precipitation evapotranspiration fluxes trapped in the canopy of the vegetation, and plant transpiration fluxes.
2.9 Carbon dioxide flux CO2flux
Unit of carbon dioxide per unit of time. Forest ecosystem carbon dioxide flux is the forest ecosystem and the atmosphere interface […]
