Abstract: Needle leaves of Mongolian Scotch Pine(MSP,Finns sylve-stris var.mongolwa).are small.Root system of MSP is distributed extensively in sandy soils in order to absorb water and nutrients.MSP is a sun plant,a cold-enduring plant,a drought-enduring plant as well as a barren-enduring plant.Its transpiration rate is higher than Pinus tabulacformis'.It has higher water potential,stronger water holding capacity,lower bound water content and ratio of bound water content to free water content,and more water saturation deficit as compared with Pinus tabulaeformis and Populus simonii.All of these morphological characters,ecological performances and physiological properties are benificial to growth of MSP on sandy lands,and to adaptation of MSP to sandy lands.

Key words: Mongolian Scotch Pine, Adaptation, Sandy land
