| 摘 要： Study is made on a 45 km-long artificial ecosystem without irrigation in Tengger desert on the basis of long-term ecological monitoring and ecohydrological fundamentals. Changes in water allocation, utilization, cycle and balance patterns in more than 40-year evolution of the soil-plant system are analyzed. The formation of a drought horizon in shrub rhizosphere and its effect, ecohydrological function of the crust and its effect on the soil-plant system is going to develop towards the steppe desert to ensure more effective use and optimum collocation of water resource.
Keywords: ecohydrology; artificial ecosystem; soil-plant evolution; water balance; drought horizon; bio-crust; Chinese desert.
