The data is divided into three parts:
1、 Environmental Variables (Data Title)
1. Overview: High-temporal-resolution meteorological and soil condition records.
2. Contents: Hourly changes in temperature, relative humidity, soil temperature, etc
3. Spatiotemporal Scope: June 27-28, 2011, at an altitude of 2700 meters
2、 Plant Water Source Data (Data Name)
1. Data overview: Water sources of dominant plants in the forest ecosystem of the upper reaches of the Heihe River
2. Data content:
● Soil profile moisture content and soil profile soil water δ 18O δ D
Dominant plants such as Qinghai spruce, Jinlu plum, Polygonum viviparum, and Stipa sinensis have water in the xylem δ 18O δ D
The contribution of different water sources to the water sources of dominant plants
3、 Stable hydrogen and oxygen isotope composition of different water bodies in the source area of the Heihe River（ δ 18O δ D) (Data Name)
1. Data overview: Stable hydrogen and oxygen isotope composition of different water bodies in the forest ecosystem of the upper reaches of the Heihe River（ δ 18O δ D) Data
2. Data content:
● Plant tissue water such as plant leaf water, branch water, and root water per hour δ 18O δ D. The time interval between the trees of Qinghai spruce is 1 hour; The time interval for shrubs such as Jinlumei, herbaceous Polygonum viviparum, and Stipa is 2 hours
● Hourly variation of atmospheric water vapor δ 18O δ D
The hourly concentration of 5cm and 10cm soil water δ 18O δ D
Autonomous production
Raw data without manual processing
Good data quality
