解釋
葉層-
Plants growing in the semi - fixed sand dunes, on the other hand, were less branchy with a larger number of first - year shoots which were longer, and grew faster ; their leaves were longer and wider with a low length / width ratio. the characteristics of the branching system and leaf dimensions of the plants in fixed sand dunes were rather intermediary between those of the above. the frequency distribution and their frequency in the herb layer the scrubs also varied with habitats

So far new variety is deficient and difficult to popularize because it is hard to know the eclolgical adaptability of plants, so we ca n ' t adjust measures to local conditions. in this paper, we systematically studied photosynthetic characteristics, light response characteristics, photosynthetic diurnal variation, growth, biomass, seasonal variation of physiological characteristics and leaf anatomy of cydobalanopsis multinervis and michelia foveolta under different shadings ( full light, one layer shading, two layers shading ) by ecophysiologi cal methods
本研究運用生理生態學的研究方法，選取目前在園林上應用較少的多脈青岡和金葉含笑的幼苗為研究材料，對其在不同遮蔭處理下（全光照、一層遮蔭、兩層遮蔭）的光合特性、光響應特性、光合日變化、生長情況、生物量、生理特性的季節變化及葉片形態解剖結構等方面進行了較為全面系統的研究。 -
The results showed that the differences of leaf thickness, cutin layer thickness, stockade tissue thickness, sponge tissue thickness, ratio of stockade tissue thickness to sponge tissue thickness, tightness of leaf tissue structure, sedimentation of leaf tissue structure and stoma density were significant, while the differences of the sizes of upper epidermis and lower epidermis were not
葉片厚度、角質層厚度、柵欄組織厚度、柵欄組織與海綿組織厚度的比值、葉片結構緊密度和氣孔密度等值越大的含笑，受旱危害愈輕，其抗旱性就越強。 -
The trees with thick cutin layer, high stoma density, thick stockade tissue, high ratio of stockade tissue thickness to sponge tissue thickness, and high sedimentation of leaf tissue structure are of greater drought resistance
