盐胁迫是影响干旱区植物生长的重要非生物胁迫，会干扰植物能量代谢过程，进而对植物的生长发育产生不良影响。盐胁迫条件下植物是否具有稳定的能量供应与其耐盐性能密切相关。本文从植物种子萌发、营养生长和生殖生长等3个阶段入手，浅析土壤盐分增加造成的渗透胁迫、离子胁迫、营养亏缺、氧化胁迫和光合损伤等对植物能量产生与消耗的影响，以期为提高干旱区植物的耐盐性能和合理利用盐碱地提供理论依据和参考。

Salt stress is one of the important abiotic stresses affecting plant growth in arid region， which affects plant energy metabolism processes and in turn adversely affects plant growth and development. Stable energy supply is closely related to salt tolerance of plants. Based on it， the energy metabolism processes of plants in the conditions of osmotic stress， ion stress， nutrient deficiency， oxidative stress and photosynthetic damage were systematically reviewed from three stages of seed germination， vegetative growth and reproductive growth. The aim is to provide theoretical basis and reference for improving the salt tolerance of plants and the rational utilization of saline land in arid regions.
