Guizhou Karst Rock Fracture, Soil Moisture, Sap Flow, and Meteorological Data

This dataset provides hydrological, ecological, and meteorological observations collected from the karst region of Guizhou, China. The data are useful for studying plant water use strategies, subsurface water movement, and ecohydrological processes in karst ecosystems. The data monitoring period spans from August 2021 to September 2024.

Dataset Contents:

Rock Fracture Water Data:

Water content and storage characteristics of karst rock fractures.

Monitoring data from different depths and apertures.

Soil Moisture Data:

Soil water content measurements from multiple soil depths.

Spatiotemporal variations in soil moisture.

Sap Flow Data:

Tree sap flow measurements to assess plant transpiration rates.

Diurnal and seasonal variations in tree water use.

Data from multiple tree species in different locations.

Meteorological Data:

Precipitation, temperature, relative humidity, and vapor pressure deficit (VPD).

Continuous weather observations from local meteorological stations.

Usage and Applications:

Ecohydrological studies of karst ecosystems.

Analysis of plant water use and subsurface water dynamics.

Model calibration and validation for karst hydrological processes.

Understanding tree water uptake strategies under varying environmental conditions.
