HiWATER: Dataset of photosynthesis observed by LI-6400 in the
lower reaches of the Heihe River Basin
Alt title:
1. Abstract
The dataset of photosynthesis was observed by LI-6400XT Portable Photosynthesis
System in the natural oasis eco-hydrology experimental area of the Heihe River
Basin. Observation items included the main vegetation type in the lower reaches of
Heihe river: Populus forest, which located in the Populus forest station and the
mixed forest station of Ejinaqi. Observation periods lasted from 2014-07-24 to
2014-07-31. This dataset included the raw observation data of the Populus forest
observed by LI-6400 during the observation periods.
1） Objectives of observation
The photosynthetic datasets can be used in the study of plant physiological
ecology characteristic and the simulation and validation for the eco-hydrological
models.
2） Instrument and theory of the observation
Measuring instrument: LI-6400XT Portable Photosynthesis System.
Measuring theory: Using the infrared gas analyzer to measure the change of CO2
concentration, and then measuring the differences of CO2 concentration between the
sample chamber and the referenced chamber so as to acquire the net productivity of
the leaf.
3） Time and site of observation
Observation site in the Populus forest station.
Observation time: 2014-07-24
Observation site in the mixed forest station.
Observation time: From 2014-07-25 to 2014-07-31.
4） Data processing
The raw data of LI-6400 were archived in text format and can be opened by text
editor or excel, the preprocessed data were in Excel format. Every time period of
observation was archived in a single document, named as “date + type”.
