ABSTRACT:
This resource contains a set of data needed to determine the water sources of two dominant woody plant species (Fraxinus Chinensis Roxb-arbor and Viburnum chinshanense Graebn-shrub) growing in thin soils of a limestone karst area located across southwest China. This set of data includes the following:
(1) Daily temperature (°C), daily rainfall (mm), and monthly soil water contents (SWC, %) of different soil layers (depths of 0–20 and 20–40 cm), which were recorded throughout the one-year sampling period (from April 2017 to March 2018).
(2) The stable isotope data (δ2H and δ18O) as to different soil layers (upper and lower soil layers), deep water (epikarst and underground river), and stem water of the plants, which were collected on September 2017 (late rainy season of 2016–2017) and March 2018 (late dry season of 2017–2018). Moreover, for each single rainfall event, rainwater samples were gathered over a one-year period (April 2017-March 2018).
