通过对沙地樟子松的抗旱指标的研究，发现叶片有发达的角质层、密度小且深陷的气孔、致密的表皮细胞、束／自比值、临界水分亏缺、蒸腾强度、叶绿素含量、以及光合作用的强弱与樟子松抗旱性密切相关。同时，树木耗水量小，单叶比叶面积小，强大的主侧根系分布均是樟于松抗旱性能的表现。
Through the research on the drought resistance index of Pinus sylvestris var. Mongolica, it was found that the leaves had developed stratum corneum, small and deep stomata, dense epidermal cells, bundle / self ratio, critical water deficit, transpiration intensity, chlorophyll content, And the intensity of photosynthesis and drought resistance Pinus sylvestris closely related. At the same time, the water consumption of trees is small, leaf area per leaf is smaller, and the distribution of powerful main root is the performance of drought resistance of Pinus pine.
