The frequency of catastrophic weather which caused by global climate warming was increased. The rate of high temperature and drought happened simultaneous was increased year by year. A detailed description on photosystem, stoma movement, signal transduction of adversity stress and regulation of stomatal open and close of plant leaf was discussed, as effect of high temperature and drought. The motion law of plant leaf stoma movement and regulation of stomatal open and close used by ABA was discussed from the angle of plant physiology and cell biology, which to provide theoretical basis of new plant variety breeding for drought and high temperature resistance, and for scientific, economic and high effective regulation stoma movement of plant leaf, which could defense short- and long-term adversity stress and guarantee grain stable and high yield finally.%全球气候变暖导致灾难性天气发生频率增高,高温和干旱同时发生的几率逐年增加,针对高温和干旱给植物带来的影响,本文从植物叶片光合系统、气孔运动、逆境胁迫信号传导和叶片气孔开闭调控4个方面进行详细阐述,从植物生理学和细胞生物学角度,讨论了植物叶片气孔运动规律及应用脱落酸对气孔开闭进行调控的研究进展,为抗旱耐高温型植物新品种选育提供理论基础,为科学、经济、高效调控植物叶片气孔运动,防御短暂和长期性逆境胁迫,保证粮食稳产、高产提供科学依据.
