Abstract:

大多数植物能够通过调节自身光合机构的功能以维持正常的生理活动和代谢水平来适应降水格局的变化，使其对环境的适应沿着有利的方向发展，但并非所有植物种都会对降水改变有相同的响应。而降水增加对植物生理生态特性的影响及其适应机制方面的研究还不够深入。本文对揭示植物叶片光合作用对降水增加响应的生理机制，进一步从生理生态角度探讨植物对降水增加的响应机制和长期的适应策略，为评估荒漠植物对降水变化的响应及合理利用植物资源进行荒漠化防治具有重要意义。
Most plants are able to adapt to changes in precipitation patterns by regulating the functions of their photosynthetic apparatus in order to maintain normal physiological activities and metabolic levels, so that their adaptation to the environment develops in a favorable direction, but not all plant species respond equally to changes in precipitation. However, the research on the effects of increasing precipitation on the physiological and ecological characteristics of plants and their adaptive mechanism is not enough. In order to reveal the physiological mechanism of photosynthesis of plant leaves in response to precipitation increase, the response mechanism and long-term adaptation strategy of plant to precipitation increase were further discussed from the point of view of ecophysiology, it is of great significance to evaluate the response of desert plants to precipitation change and to make rational use of plant resources.
