Measurement data of horizontal gas exchange of photosynthetic organs of desert plants in different habitats in Heihe River basin (2013)

As determined in mid-august 2013, planting species: bubbly spines (different habitats are mid-range intermountain lowland and gobi), red sand (different habitats are mid-range gobi and downstream gobi).

Using the brother company of LI - 6400 Portable Photosynthesis System (Portable Photosynthesis System, LI - COR, USA) and LI - 3100 leaf area meter, etc., to the desert plant photosynthetic physiological characteristics were observed.

The symbolic meaning of the observed data is as follows:

Obs，observation frequency ； Photo ，net photosynthetic rate，μmol CO2•m–2•s–1；

Cond stomatal conductance，mol H2O•m–2•s–1 ; Ci, Intercellular CO2 concentration, μmol CO2•mol-1；

Trmmol，transpiration rate，mmol H2O•m–2•s–1； Vpdl，Vapor pressure deficit，kPa；

Area，leaf area，cm2； Tair，free air temperature ，℃；

Tleaf，Leaf temperature，℃； CO2R，Reference chamber CO2 concentration，μmol CO2•mol-1；

CO2S，Sample chamber CO2 concentration，μmol CO2•mol-1； H2OR，Reference chamber moisture，mmol H2O•mol-1；

H2OS，Sample chamber moisture，mmol H2O•mol-1； PARo，photon flux density，μmol•m–2•s–1；

RH-R，Reference room air relative humidity，%； RH-S，Relative humidity of air in sample room，%；

PARi，Photosynthetic effective radiation，μmol•m–2•s–1； Press，barometric pressure，kPa；

Others are the state parameters of the instrument at the time of measurement.
