This showed that capacity of water-holding in biological soil crusts were obvious improve,and effected precipitation permeate or water second distribute process.The study results of"fertile islands"formation mechanism in biological crusts showed that biological crusts layer cover could increased nutrients content for below sand soil through precipitation permeate washing,and it promoted plants assimilate more nutriment.The matter import ways of biological soil crusts fertility island had many ways,including the effection of living macrobiotics metabolism in crusts levels,wind-sand flow of near surface,dust deposition and plants decomposition course,etc.Source of particle matter in biological soil crusts was wind-sand flow of near surface,and not dust deposition.Biological crusts layer cover had preserved effection for nature water content in 0-5cm soil layer,compared with the sand of no biological crusts layer,effecting precipitation permeate,and could not obvious restrained from the water evaporate process indoor experiment.

生物结皮层肥岛形成机制的研究结果表明：生物结皮层覆盖能够通过降水淋溶作用而增加下层土壤养分的含量，进而促进植物对养分的吸收；生物结皮层养分输入有结皮生物代谢、降尘、风沙流和植物分解矿化作用等多(来源：A73e3B3eC论文网www.abclunwen.com)种途径，但生物结皮层的颗粒物质来源主要是近地表风沙流，而不是大气降尘；生物结皮层覆盖对0-5cm土层自然含水量有一定的保护作用，并影响降水向深层渗透，不能有效的阻止表层水分的蒸发进程；研究表明采取人工促进技术能够在流动沙丘上形成生物结皮层，实现流动沙地的快速治理。

The results show that the radial stress and tangential stress with considering the influence of seepage water pressure are larger than those without considering the influence, and this makes the plastic zone of surrounding rock expands. When the seepage factors of surrounding rock and liner are obviously different, they are not simplied as one and the same.

It is common knowledge and rather obvious that contemporary art and pop culture have been influencing and mixing up with each other with ever stronger momentum. Generally speaking, such phenomenon is caused by the following factors: first of all, pop culture is an unavoidable existence in the field of the contemporary social culture, especially in urban culture. Elements of pop culture are always employed by artists who attempt to present the modern social life in a critical, ironical or neutral way. But their standpoint and intention of choosing the visual resources are different from that of the mass media and the public.

众所周知，在当代社会中艺术与大众文化的相互渗透、混杂的现象已经明显加剧，造成这种现象的原因大致有这么几点：首先，大众文化是当代社会文化领域，特别是都市文化领域中一个不能回避的问题，不管艺术家是处于批判、反讽或者是不动声色的呈现当代社会生活的时候都涉及到运用大众文化形态的问题，只不过艺术家选择这些视觉资源的时候其出发点及立场与大众传媒和社会公众不同。

As one of the most important osmoregulation actor, firstly,Proline plays a keyrole in the osmotic potential adjustment in plant cells. Secondly, Proline can preventNaCl from damaging the structure of biomacromolecule in cells. Thirdly, the highdissolubility and non-rejection capability of Proline can enlarge the solution volumnof the cell, so the concentration of salt will be diminished in cytoplasm and the saltstress will be relieved. Forthly, the accumulation of Proline could prevent thedehydrolysis from sap cavity in cytoplasm. Fifthly, the synthesis of plant chlorophyllwill be diminished under the salt stress, but the Proline can provide request ofchlorophyll synthesis.

脯氨酸作为渗透调节剂对植物体细胞渗透势的变化起重要作用：一，在盐胁迫下，脯氨酸在植物体内是一种重要的渗透调节剂，它是一些高等植物和绿藻抗盐和抗旱的主要渗透剂之一；二，脯氨酸可以保护细胞中的生物大分子的结构，使之不被NaCl破坏，并能维持其完整的水合范围；三，脯氨酸的高度溶解性以及其对植物各种酶活性不抑制性，可以扩大细胞的溶解容积，从而降低细胞质液中盐的浓度，减轻盐的胁迫作用；四，细胞质中积累的大量脯氨酸可以防止液泡对细胞质的脱水作用；五，在盐胁迫下，植物叶绿素的合成受到抑制，叶绿素的合成需要脯氨酸。
