摘　　要：干旱是生物圈中限制高等植物生长、发育和分布的主要因素之一,土壤干旱和大气干旱都会导致植物水分的亏缺。研究了解植物在干旱环境条件下的理化及生态特征,能够为探索某种植物抗旱性生理生态机制、培育抗旱新品种以及提高植物水分利用率等提供理论依据。本综述就近几年植物在干旱胁迫下的响应机制以及适应能力进行了综述,以期为今后研究植物抗旱性能提供参考。Drought is one of the main factors that limit the growth, development and distribution of higher plants in the biosphere, and soil drought and atmospheric drought can both lead to the loss of plant water. To research and understand the physicochemical and ecological characteristics of plants in arid environment can provide a theoretical basis for exploring the physiological and ecological mechanisms of plant drought tolerance, cultivating new varieties of drought resistance and improving the water utilization rate of plants, etc. The response mechanism and adaptability of plants under drought stress in recent years were studied in this review, which aimed to provide references for future research on drought resistance of plants.
