Introduction to the Water‐Soil‐Air‐Plant‐Human Nexus: Modeling and Observing Complex Land Surface Systems at River Basin Scale

Abstract: Bidirectional coupling of complex human‐nature system can be referred to as water‐soil‐air‐plant‐human nexus, and integrated studies of this nexus have been carried out in many river basins around the world. This special issue reports contributions for modeling, observing, and understanding of water‐soil‐air‐plant‐human nexus at river basin scale, particularly those from the “Integrated research on the eco‐hydrological process of the Heihe River Basin” program. This paper highlights key results as an introduct… Show more

“…In a way, it is necessary to describe the water-soil-air-plant-human nexus to maintain precisely an irrigation district system, not just some factor alone. Similarly, the watershed, a self-organized complex system containing numerous elements at various scales, was regarded as the best unit to carry out the water-soil-airplant-human nexus experiment [45]. Yet, when studying the heterogeneity in soil moisture, evapotranspiration, and other related ecohydrological variables, two key issues including scaling and uncertainty are still challenging with multiscale observations through integrating satellite, aerial, and ground observations in a watershed [46].…”

“…(Liu et al 2018;Zhang et al 2020). The con guration results include the usage of different water sources at different times, the optimal crop planting structure, and the rational planning of land use types (Mosleh et al 2017;Li and Xie 2019). With the continuous development of computing, computer optimization algorithms for solving multi-objectives have been applied to the process of optimal allocation of water resources and optimization of land resources.…”
