摘　　要：植物水势是植物水分生理研究最常用的指标之一。作者对植物水势的研究与应用状况进行了综述,提出利用植物水势,结合气孔导度、相对含水量、水分利用效率等生理指标,对我国主要物种,特别是森林树种的等水/变水行为特征进行深入研究,为确定合理灌溉指标、人工林营造及生态系统保护等提供理论依据。Plant water potential was one of the most common indexes in plant water physiology research. The research and application situation of plant water potential were reviewed by author. The main species in China, especially isohydric/an - isohydric behavior characteristic of was deeply researched by applying the plant water potential, combined with stomatal conductance, relative water content, water use efficiency and other physiological index was raised. It provided theoretical foundation for determining reasonable irrigation index, plantation building and ecological system protecting.
