查询词典 dune

The results showed the seeds of ephemerals mainly distributes in 0～5 cm soil and there are few seeds under the 5 cm soil.The density of the seed banks is different among the different parts of the sand dune.The density decreases gradually from the foot to the top.

结果表明：短命植物种子主要集中分布于地表0～5 cm土壤中，5 cm以下土壤中极少存在有活力的种子；沙丘间及沙丘不同部位的种子库密度大小不同，密度自坡底随高度增加逐渐减少，坡底、坡中部及坡顶部密度分别为124粒/m2、91粒/m2、66粒/m2。

The density of the foot 、middle part and top are 124grain /m~2、91 grain /m~2、66 grain /m~2,the seeds is more little windward than the leeward.The density of seed banks in windward is 81grain/m~2 and the leeward density is 100grain/m~2.The seed of ephemerals bourgeoning reaches the pinnacle on April and May.The diversity of different parts sand dune is different,but the differences do not reach the marked level.The similarity is high between the seed banks and the vegetation.

迎风坡种子库密度比背风坡面少，迎风坡种子库平均密度为81粒/m2，而背风坡种子库平均密度为100粒/m2；短命植物种子在4月上旬达到萌发高峰，沙丘不同部位物种多样性存在差异，土壤种子库和地上植被存在较高的相似性，此外短命植物在沙丘不同部位的分布存在较高的空间异质性。

As pioneer plants, desert spring ephemerals play an important role in community succession, biodiversity maintenance and dune stabilization in desert ecosystems. We studied the diurnal changes in gas exchange of three desert spring ephemerals (Eremopyrum orientale, Malcolmia scorpioides, and Tetracme quadricormis, hereafter the genus names only) under natural conditions in the desert area of the Dzungaria Basin.

采用LI-6400便携式光合测定仪，在晴天条件下对准噶尔荒漠3种典型短命植物东方旱麦草、卷果涩芥和四齿芥的气体交换特征的日变化规律进行了研究。

In wetter habitats, forbs were more abundant and accounted for the majority of aboveground biomass, whereas grasses became more important in dryer habitats. Shrubs and sub-shrubs increased with decreasing soil water availability and their relative biomass rapidly increased in degraded steppe and sand dune; perennial grasses had significantly higherδ〓C values than other PFGs; the δ〓C values of perennial grasses and forbs increased with decreasing soil water availability, while those of shrubs/sub-shrubs showed an inverse trend.

在较湿润生境，多年生杂类草更加丰富并构成了群落地上生物量的绝大部分；而在较干旱生境下，多年生禾草在群落中起更重要的作用；随着土壤含水量下降，灌木和半灌木逐渐增多，且在退化草地和沙地中其相对生物量迅速增加；多年生禾草δ〓C值显著高于其它功能群；随着土壤水分可利用性降低，多年生禾草和杂类草的δ〓C值表现出增加的趋势，而灌木/半灌木则表现出相反的趋势。

Gaze on haze and days of fades: You'll see phases of L's and K's in gold rays Praise my shades by maze of phrase: We'll see pays by laze in old ways (life of lies,typed life I'm a rhyme,in this time life of lies,typed life I'm a rhyme,in this time) That has all of my fortune But was called on for his fore tune What does wall do well for dune?
