本数据为基于民勤县有器测以来的降水资料（1953-2018年），根据1%和99%分位点定义极端干旱（降水）指数，确定5个干旱胁迫梯度（增雨70%、增雨35%、对照、减雨35%和减雨70%）。通过遮雨棚人为制造减雨梯度，遮雨棚截留的降水通过重力自流式滴灌系统增加到对应增雨样地。利用水分传感器（5TM, Decagon Devices, Inc.）连续监测不同干旱胁迫下的柽柳林地土壤湿度。", "ds_source": "

This data is based on the precipitation data from instruments in Minqin County from 1953 to 2018. According to the 1% and 99% percentile definition of extreme drought (precipitation) index, five drought stress gradients were determined (70% increase in rainfall, 35% increase in rainfall, control, 35% decrease in rainfall, and 70% decrease in rainfall). By artificially creating a rainfall gradient through a canopy, the precipitation intercepted by the canopy is increased to the corresponding rainfall increasing sample plot through a gravity gravity gravity drip irrigation system. Using a moisture sensor (5TM, Decagon Devices, Inc.) to continuously monitor soil moisture in tamarisk forests under different drought stresses.
