沙棘有很强的根蘖能力，其根系具有类似水生植物根系的解剖特征，地上部分又有旱生植物的特征，所以沙棘应属中生植物；

Common seabuckthorn has strong tillering capacity , its root system has the dissecting characteristic similar to the root of hydrophyte , while its above-ground part has the characteristic of xerophyte , so common seabuckthorn belongs to mesad .

中生植物主要是通过增加气孔阻力限制蒸腾失水，而旱生植物则依靠高浓度的细胞原生质减少水分的散失，后者保水效率远高于前者。

Mesic plants limited water loss from transpiration by increasing their stoma resistance , while xeric plants decreased water loss by keeping the high concentration of cell protoplasm . The latter had a higher efficiency of keeping water than the former .

Mesophytes have the greatest number in water ecological form , which has 577 species accounting for 61.1 % of the total species ; xerophyte is in the second order , with 291 species accounting for 30.8 % of the total species ;

旱生、中旱生植物7种，旱中生、中生植物5种；

Species were xerophyte or mesic xerophyte , 5 speices were mesophyte or xeric mesophyte .

故中旱生植物和多浆旱生植物并不主要依靠积累脯氨酸来调节渗透势确保水分的供应。

Thus succulent xerophytes and mesophytes did not mainly depend on accumulating free proline to adapt to arid environments .

中旱生植物的变异性也较低，在群落层次上，地上生物量的年度间变异系数为13.16%～23.62%。

The variability of intermediate xerophytes is low at ecological type functional groups . At community level , the yearly coefficient variation of aboveground biomass is in the range of 13.16 % ~ 23.62 % .

从不同的生活型和水分生态型来看，多年生根茎禾草和中旱生植物起主导作用，总密度的变化基本与它们的变化是一致的。
