旱

Having long lived in rigor habitats,two extreme xerophytes Reaumuria soongorica and Salsola passerina formed special biological features and physio-ecological adaptations.

超旱生植物红砂与珍珠长期生活在严酷的生境中，形成了独特的生物学特性和生理生态适应性。

The allomatric scaling for the wet clonal plants including Phalaris arundinacea Scirpus planiculmis Phragmites australis and Phragmites Jeholensis did not show "1/4-power Rule". The variation of the allometric exponents between vegetative and reproductive ramets was mainly due to the different regulation mechanisms in different development stages. Moreover, the variation of the allometric exponents between plantsin wet or drought environments was the result of the long-time divergent response for ramets to moisture environments.

虉草、紧穗三棱草、芦苇和热河芦苇4种湿地根茎植物分株异速生长规律并不表现为&1／4或1／4整倍数&规律，营养株和生殖株异速生长幂值的差异是不同发育类型的分株生长调节机制不同的结果，水生生境和旱生生境分株异速生长幂值的差异则是分株对生境水因子差异长期趋异响应的结果。

Maximum can resprout and grow faster than M. sinensis in wet season which may help the species in competition for resource uptake after fire.

不管在水分或光度处理实验都发现大黍比芒草有显著较多的枯枝落叶，而且更容易受到乾旱压力的影响而枯叶。

MAYOR: It's all around us-- runted crops, field fires, bankruptcies... This drought is destroying people's lives, and it's wrong for a single man to pprosper at the expense of others.

市长：是在我们四周－农作物收成不好、田野大火、破产…这个乾旱毁了人们的生计，都是因为有个人想要跟别人收费，而导致的错误。

Firstly, influenced by climate, topographical feature, soil and hydrological and geographical features, there was drought, flood, salinification, desertification and barren in Daxing, biological protection is necessary as a protective barrier to control sand from Yong Dinghe River bed Secondly, the windbreak system has features of urban forestry with aesthetic character and reasonable forest structure and arrangement.

首先，受气候、地貌、土壤和水文地质等多种因素制约，旱、涝、碱、沙、瘠等自然灾害普遍存在，防护林体系的生态环境保护作用应当得到充分体现，要成为首都&南大门&的生态屏障保护及永定河沙地的风沙源控制带。其次，要体现大城市城郊防护林体系的建设特点，布局合理，结构合理，具有一定的风景美学价值。

Among 10 sampling plots selected,only Sophora alopecuroides, a plant with strong drought resistance grown on the top of the dune,only two accompanying species,such as Salsola ruthenica and Leymus secalinus occurred.

选择的10块样地中，只有耐旱能力很强的苦豆子生长在含水量较少的沙丘项部，主要伴生种只有沙蓬和赖草，赖草、沙蒿、猫头刺和柠条6块样地均分布在水分条件相对较好的沙平地，主要伴生种有10种。

By statistical analysis of the 30 years rainfall of Luoyang,Henan Province,the different patterns of annual precipation were stimulated and the water proof sheld was used to study the effects of different compositions of N,P and water on the yield of winter wheat.

本文通过统计分析洛阳地区近30年的降雨量，模拟洛阳地区不同的降雨年型，利用防雨旱棚研究旱地农田不同N、P、水配合对小麦产量影响。

Sequence analysis and homology alignment showed that MD1 had 93% similarity with matK in maize chloroplast genome, a gene encoding maturase included in type Ⅱ intron splicing of RNA transcript; MD2 had 99% similarity with gene PP2C, encoding serine / threonine protein phosphatase type 2C in extremely drought tolerant Sporobolus stapfianus; and MD3 had 99% similarity with rice gene encoding metacaspase, belonging to aspartic acid specific cysteine caspases.

序列分析和同源性比对表明，MD1与玉米叶绿体基因组中编码参与RNA转录本Ⅱ型内含子剪切的成熟酶的matK基因有93%的相似性，MD2与极端耐旱的Sporobolus stapfianus的丝氨酸／苏氨酸2C型蛋白磷酸酶基因PP2C的相似性达99%，MD3与属天冬氨酸特异性半胱氨酸蛋白酶类的水稻metacaspase基因有99%的相似性。

Results of sequence and homology analysis show that MD 1 has 97% similarity with mark in maize chloroplast genome,a gene encoding RNA maturase involved in group Ⅱ intron splicing of RNA transcript;MD2 has 99% similarity with the gene serine/threonine phosphorylase 2C in Sporobolus stapfianus;and MD3 has 99% similarity with rice the gene encoding metacaspase,an arginine/lysine-specific cysteine protease.

序列分析和同源性比对表明，MD1与编码成熟酶的玉米叶绿体基因matK有97%的相似性，MD2与极端耐旱植物Sporobolus stapfianus编码丝氨酸/苏氨酸蛋白磷酸酶的PP2C基因有99%的相似性，MD3与属精氨酸/赖氨酸特异性半胱氨酸蛋白酶类的水稻metacaspase酶基因有99%的相似性。根据MD2片段序列，结合电子克隆和RT-PCR方法，克隆出一条1731 bp的全长cDNA序列，它编码388个氨基酸。
