Please note that some of this document may be patentable. The issuing agencies of this document do not bear the responsibility of identifying these patents. This standard is proposed and managed by the State Forestry Administration. This standard was drafted by the Institute of Forest Ecology, Environment and Protection, Chinese Academy of Forestry. The main drafters of this standard. Wang Bing, Niu Xiang, Jiang Youxu, Guo spring water, Liu Shirong, Yang Fengwei, Song Qingfeng. Forest Ecosystem Long Term Observational Index System1 ScopeThis 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 definitionsThe following terms and definitions apply to this document. 2.1 Soil organic carbon component soilorganiccarbonfraction 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 volumeofrunoff 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 forestevapotranspiration 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 leafareaindex The ratio of total plant leaf area to land area per unit area of land. 2.7 Soil respiration soilrespiration 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 ...... |
