海拔梯度对药用植物品质形成影响的研究进展

药用植物品质的形成主要受基因资源、栽培技术和环境资源等要素的影响。而海拔梯度由于包含了多种环境资源要素的剧烈变化，因而成为研究植物生理生态和发育进程在环境资源梯度格局上变化的理想“天然试验场”。系统综述了海拔梯度对药用植物的形态结构、生理生态特征、生长发育和品质形成等的影响，分析了该领域的研究特点及其存在的问题，指出了未来研究的重点和方向。

Advances in Influences of Altitudinal Gradient on the Distribution and Quality Formation of Medicinal Plants

The quality formation of medicinal plants is affected by the genetic resources, cultivation techniques and environmental resources, etc. The altitudinal gradient incorporates dramatic changes in many kinds of environmental resources, and thus becomes the most powerful ＇natural experiment＇ for testing ecological and evolutionary responses of flora to geophysical influences. In this paper, the influences of altitudinal gradient on the morphological responses, physiological and ecological characteristics, growth and development, quality formation of medicinal plants were reviewed, the present researches were discussed, and then the emphasis and direction of future study in this field were put forward.
