沙棘的生物学与生态学特性

沙棘生物学与生态学特性一直是众多学者关注的焦点之一，众多学者在叶表皮毛特征、根系解剖结构和生物固氮方面已经取得了基本一致的看法，但在水分生理生态和种群坟散方面尚存争议或不理解之处。这主要是由于忽视了沙棘无性系植物种群的生理整合作用和觅养行为。因此，今后应该从无性系生长可塑性调节和分株间资源共享特征出发，进一步探讨沙棘的抗旱机理和生态适应对策。

The biological property and ecological habit of Hippophae

The biological property and ecological habit of \%Hippophae\% was one of the focus for numerous studies,and a consistent opinion was achieved in the traits of epidermal hair,root anatomical structure and biological nitrogen fixation.Some differences,however,still existed in water ecophysiology and population dispersal because of the neglect of physiological integration and foraging behavior of clonal plant population.Therefore,more studies on the mechanism of drought resistance and ecological strategies should be focus on the regulation of growing plasticity and resource sharing among ramets within a clone.
