The correlation analysis between 30 morphological characters with significant difference and climatic factor, longitude and latitude can be summarized as:(1) the longitude, precipitation and air humidity have the same effects on the variability of G. uralensis;(2) the index number affected by light is the most, and the water is the most important factor affecting population variability of G. uralensis.(3) the variability shows that the height of plant, the number of small leaves of the compound leaf, the number of flower buds and the length of inflorescence increase with the increasing of climatic humidity, however, the number of lateral branch decreases.

对30项具有显著差异的指标与气候因素和地理经纬度进行的相关分析结果可概括为：（1）地理经度对变异的作用与降水量和大气湿度相一致；（2）光照因素影响到的指标最多，水分因素对变异的作用程度最大；（3）变异的主要表现为，随气候湿润程度增加，植株的高度、复叶小叶片的数量、花序的长度和花蕾数量等均呈增加趋势，而侧枝的分枝数量和长度呈减小趋势。

Beijingensis under three droughttreatments, normal, moderate and severe stresses. The results showed:(1) the canker disease ofboth cultivars was serious gradually with increased drought;(2) the bark tissue cells sufferedplasmolysis, more evident with the severity of drought stress;(3) under the drought andinoculation with B. dothidea, cells of two cultivars damaged at different degree, mailyrepresented in the changes of organelles, such as chloroplast swollen and distorted, number ofmitochondria increased and membrane system indistinct; then organelles suffered furtherdamagement with inoculation time, thinned mitochondrias stroma, decreased cristae, crumpledand partly broken membrane of chloroplasts with stroma exosmosis. At last, the chloroplastspartly disorganized;(4) the hyphae growed mainly intercellular in resistant cultivar and notonly intercellular but also intracellular in susceptible cultivar, which directly caused thenecrosis of cells;(5) under the severe drought, the damage of cells enhanced the infection ofpathogen and drought and pathogen stressed together and promoted the disease development;the damage from pathogen on cells was more serious than that from drought.

结果显示：(1)随着干旱胁迫程度的增加，2种杨树溃疡病害发生渐趋严重；(2)干旱胁迫下，杨树树皮组织细胞发生质壁分离，并随胁迫程度的增加而严重；(3)干旱胁迫下接种病原菌，2种杨树细胞发生不同程度的损伤，主要表现为细胞器发生较大变化，如出现叶绿体肿胀变形、线粒体数量增多，质膜模糊不清等现象；随接种时间的延长，细胞器受到进一步损伤，叶绿体被膜折皱，严重时局部破裂，基质外渗，并部分最终解体；(4)毛白杨中的菌丝主要在细胞间隙中穿行，而北京杨的菌丝除在细胞间隙中生长之外，侵入细胞内部也较多，直接导致细胞的解体；(5)干旱胁迫下细胞的损伤促进了病原菌的侵染，干旱和病原菌的双重胁迫加剧了病害的发生程度，并且病原菌侵染对细胞的破坏程度大于水分胁迫。

In this paper, the characteristics of the wetland ecosystem of the Poyang Lake national nature reserve are discussed through considerations of the hydrography, soil, biological composition and system function.

鄱阳湖是我国最大的淡水湖。鄱阳湖自然保护区以其独特的地形地貌，在亚热带湿润季风气候综合作用下，形成了一个多功能的复合湿地生态系统。根据湿地三条划分标准：有充分的水分、有机质含量较高的土壤及适应于此环境的植被。鄱阳湖自然保护区属淡水湿地生态系统。

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。

Our best scenario for natural snow is when moisture from an Atlantic storm system collides with the polar jet stream dipping far into the south east Appalachians – a phenomenon that happens far too seldom to run a profitable ski resort throughout the season.

我们最好的天然雪的情况是，当水分从大西洋风暴系统的碰撞与极地喷气流浸远到阿巴拉契亚山脉的东南-这种现象很少发生太多运行一个有利可图的滑雪胜地整个赛季。

From the tests,we have obtained some structural variant features related with salt resistance and demonstrated the successful introduction of Rhizophora apicularta DNA into tomato.This thesis contains two parts. In the first part,the morphological and anatomical structures of the leaves were investigated. As to the morphology,some difference between control and transformed tomato were found. The leaf dimensions of the transformed tomato with unextended leaves were smaller than that of control. These structure changes should help to decrease the evaporation of water effectively and release the physiological drought resulted from saline.

本实验分两部分：第一部分、对转化番茄的形态及细胞显微结构进行观察与分析，实验表明转化番茄形态与对照相比有明显的变化，其叶面积变小，叶形收拢，这种结构可有效地减少水分的蒸发，缓解由盐胁产生的生理干旱；组织解剖结构结果显示，耐盐番茄在细胞结构上发生了明显的变异：其气孔器倾向下陷，表皮毛增多，叶脉微管组织不发达，微管束周围出现增多的贮水细胞，叶缘及其它部位表面分化出大型的多细胞分泌型结构，这些结构与转化番茄后代较强的耐盐能力有关。

The results showed that at the beginning stage of being attacked by Chinesis white pine beetle and their symbiotic blue-stain fungus, PAL, PPO, SOD activities and MDA content significantly increased in the phloem of P. armandi, and decreased with the increase of the number of D. armandi and the attacking on the xylem and phloem of P. armandi from blue-stain fungus, then reached the minimum level in withering stage of P. armandi. But the contents of nutrition materials in the phloem, such as water, protein, glucide, fat, amylum and so on, declined with the infestation of D. armandi and symbiotic fungus. In summary, the resistance of physiology and biochemistry in the phloem of P.

结果表明，在华山松大小蠹和共生蓝变真菌危害初期，华山松韧皮部内的苯丙氨酸解氨酶、多酚氧化酶、超氧化物歧化酶活性均显著提高，丙二醛含量明显增加；但随着华山松大小蠹种群数量的增加和蓝变真菌对华山松韧皮部和木质部组织危害的加剧，韧皮部组织内的PAL、PPO和SOD活性逐渐降低，在枯立木阶段降至最低；与此同时，华山松韧皮部内的水分及蛋白质、糖类、粗脂肪、淀粉等营养物质含量，则随华山松大小蠹和共生蓝变真菌危害的加剧而不断减少。

Unlike most of the other desert plant species, which have small leaves so as to minimize moisture loss, this plant is unique in that its leaves are particularly large; each plant's rosette of one to four leaves reaches a total diameter of up to one meter. Prof. Simcha Lev-Yadun, Prof. Gidi Ne'eman and Prof. Gadi Katzir came across this unique plant growing in the desert while studying the field area with students of the Department of Science Education-Biology of the University of Haifa-Oranim, and noticed that its leaves are unusually large and covered with a waxy cuticle.

不同于其他大多数沙漠植物，利用小的叶片来减少水分的散失，这种植物的叶片特别的大，一株沙漠大黄可以有1到4片圆盘状的叶片，直径最多可达1m，海法大学的教授Simcha Lev-Yadun、Gidi Ne'eman和Gadi Katzir在带领学生在此地作调查的时候发现了这种植物，他们发现这种植物的叶子不寻常的大，并且覆盖了以层蜡质。

Also with light tea alternate feed. 4, if necessary, go to the hospital drips, add water, electrolytes and glucose, to prevent dehydration and acidosis. 5, breast milk contains more lactose, most lactose enzyme decomposition of absorption and less by the Department at the end of fermentation to digest the lactose, producing gas, acid production, stimulate the intestinal tract, so that stool was diarrhea-like discharge. 6, breast and milk contain fat, part of being broken down into fatty acids and glycerol absorption, not alkaline digestion of fat in small granular form of calcium soap, so that stool can not appear in the first one to digest things.

还可与淡茶水交替喂。4、必要时去医院打点滴，补充水分，电解质和葡萄糖，以防脱水和酸中毒。5、母乳中含乳糖较多，大部分被乳糖分解酶分解吸收，少部末被消化的乳糖发酵、产气、产酸、刺激肠道，使大便呈腹泻状排出。6、母乳和牛乳均含有脂肪，一部分被分解为脂肪酸和甘油吸收，未被消化的脂肪碱性的钙形成小颗粒状的肥皂，使大便中出现消化不掉的一颗一颗的东西。
