Special Issue Information

Dear Colleagues,

The complex plant-water interaction, from leaves to the biosphere, with its feedback to the climate system, is one of the most uncertain parts of the water cycle. It involves interactions of soil, plants, land cover, and land use, with hydrological processes, such as evapotranspiration, infiltration, and runoff. There are still many unsolved problems in the observation and simulation of these processes (e.g., evapotranspiration partitioning;  effects of soil structure on hydrological processes;  identifying runoff channels). Understanding these processes can greatly improve our knowledge of and ability to adapt to changes in water cycles in changing environments, especially in arid and alpine regions.  

In this Special Issue, we welcome the submission of studies that investigate both facts and mechanisms related to plant-water processes, from leaves to the biosphere’s effects on hydrological processes, including soil-water dynamics, evapotranspiration, and runoff.

The topics covered by this Special Issue will include, but are not limited to, the following:

  • Plant-water interactions in arid and alpine catchments;
  • Advances in hydrological and ecohydrological monitoring techniques and  modelling;
  • Isotop tracers in plant-water interaction studies;
  • Evapotranspiration partitioning;
  • Soil structure effects on hydrological processes;
  • Identifying flowpath of runoff;
  • Impacts of human activities on the hydrological cycle.

Quantification of the water budget of an arid inland river ecosystem is essential but still a challenge for the sustainable development of water resources. In situ observed data were used to analyze the monthly and annual water budgets and the soil hydrological cycle for six typical ecosystems in the Heihe River Basin (HRB). The two-source model was used to partition evapotranspiration (ET) into transpiration (T) and evaporation, after which the validated model was applied to quantitatively analyze the biological water use fraction [T/Ecosystem Water Supply (WS)] for different ecosystems. There were differences in the water budgets of the different ecosystems due to differences in climate, vegetation, soil, and external inputs. Precipitation in the HRB decreased from upstream to downstream, whereas there was a gradual increase in ET. External sources of water (e.g., natural runoff from upstream, irrigation in the middle reaches, and groundwater recharge in the lower reaches) to soil layers played an important role in regulating the water budgets of HRB ecosystems. Cropland obtained the maximum biological water use fraction (0.50), followed by Populus euphratica (0.49), alpine meadow (0.49), alpine swamp meadow (0.44), Tamarix ramosissima (0.42), and Kalidium foliatum (0.4). The soil water residence time (at a depth of 40 cm) varied from 14 d to 97 d (average of 60 d). The order of plant species in terms of soil water residence time was: K. foliatum (88 d) > T. ramosissima (72 d) > alpine meadow (68 d) > alpine swamp meadow (63 d) > cropland (53 d) > P. euphratica forest (20 d). Differences in the biological water use fraction and soil water residence time could be attributed to the characteristics of the water budget for each ecosystem. This study quantified the water budget, biological water use, and soil hydrological cycle across typical ecosystems in HRB, and can act as a reference for ecosystem management of the arid inland river basin.
