Due to globe climatic changes and environmental factors are complex and unrepeatable, it becomes very dif? cult to quantitatively research on effects of plants response and adaptation to the water de? cit environments. Therefore, the simulation natural climate under the control environment is an irreplaceable and ideal technical means for scienti? c research. In this paper, we introduced the drought environmental simulating phytotrons, which was developed by the Institute of Soil and Water Conservation. As a case study, we summarize
