生态种的

Due to their modes to adapt to arid condition, ecological and physiological responses and the changes of structure are all different, but their mechanism to adapt to the sandy soil water changing is consistent, consequently they have more chances to exist in the entironment what has biggish annual wave of climate comparing to mostly plants that bourgeon in early spring.

由于对干旱生境的适应方式各不相同，其生理生态反应和结构的变化因种而异，但对沙土水条件的适应机理却是近似的，从而在年际气候波动较大的生境中，这几种植物较早春期萌发的大部分植物幼苗有较多的存在机会。

At last, according to the above discussions, the author draws a picture of the leadership for the 21 century. On all accounts, the author concludes that the efficiency of leadership must be understanding of reality, and there're some commonness as well as individuality. As an educational leader, he must recognize the character of leadership in ecospecies, pay special attention to the staffers, shift the organizational function, focus on his inner development, and achieve the state of "Unleadership".

由此，笔者认为：领导有效性是一种具体环境下领导绩效的展现，它既有共性，也有个性，它既表现在宏观层面，又体现在一些细微方面；从追求未来领导走向成功的角度出发，未来领导者应该注意领导工作的"生态性"，重视"人"的问题，有效转变机构职能，关注自身发展，求得一种领导者"隐退"的境界。

The best conditions of removal is that the water level of 0.5m, figuline granule bed, shale substrate, hybrid aquatic plants including fox brush alga, yellow flower fleur-de-lis and xero-grass regarded as vanguard vegetation in submerged bed, with TN removal of 79% and reliability of 95%.

经正交表L9(3^4)完全试验中81种组合形式的工程平均估计和数量化方程的预测，这两种统计方法所得结果是吻合的，其结果可作为实施污染水体生态修复时的参考。

The SARS virus origin which obviously differs from the theory of out space origin and the theory of wildlife origin was theoretically discussed based on principles of pollution evolution ecology,pathogenesis and infectant characteristics of SARS,and some relevant experimental evidence. It emphasizes on the fact that increasingly combined pollution in China provides a substantial basis for virus evolution.

针对当前广为流传的SARS病毒"太空起源说"和"野生动物来源说"两种理论，本文根据污染进化生态学原理和SARS病毒发病传染特征，以有关实验结果为科学依据，阐述了SARS病毒的起源问题，指出：我国当前环境日益严重的复合污染为SARS致病病毒的产生提供了适宜的外部生态条件和物质基础，SARS致病病毒可能起源于多个病毒的基因重组或融合，更可能是一种来自于感冒病毒进化而形成的超级感冒病毒。

There are about 100 species plants in the wetland, and the majority is herbage and frutex. These plants included Polygonum hydropiper, Nelumbo nucifera, Annua Linn, Phragmites communis etc. At the same time, there are also 48 species animals, which belong to 30 families, and these animals included Ciconia ciconia, Cygrus cygrus, Platalea leucorodia, Meles meles etc.

湿地内有高等植物近100种，其中草本和灌木占大多数，典型的如水蓼、莲藕、早熟禾、芦苇等；在此栖息的动物有5纲共18目30科48种，具有代表性的如黑鹳，大天鹅、白琵鹭、狗獾等，是铜川市重要的水源补给地和湿地保护区，对于当地生态环境和经济社会可持续发展意义重大。

Basing on our early stage research work about collection and description of sugarcane germplasm and the aided project of Yunnan Natural Science Fund (2001 C0015Q), the wild species Erianthus fulvus, which has good characters, cold-resistant, drought-resistant, higher Brix and less chromosome number, was utilized for the first time through intergeneric hybridization with sugarcane cultivar. Its F_1 hybrids were appraised with some new techniques and methods for germplasm enhancement.

本研究在课题组考察采集和保育鉴定甘蔗野生种质资源的前期工作基础上，依托云南省自然科学基金资助项目(2001C0015Q)，首次利用具有特异优良性状(抗旱、耐寒、锤度高、染色体数目少)的蔗茅野生种与甘蔗栽培种或品种进行属间远缘杂交，扩大甘蔗遗传多样性；采用新技术、新方法对蔗茅杂种F_1代材料进行早期鉴定评价研究，筛选具有育种价值的新种质，为进一步选育生态适应性广、抗逆性强、丰产高糖的甘蔗新品种奠定物质基础。

Here, we took demonstration study of the ecological impacts of disconnection from the river on fish recources in Zhangdu Lake. Our results showed that:(1) Fishery mode changed and the rate of wild fishery production changed from 95% in 1949 to less than 5% in 2002.(2) Fish species have decreased from 80 in 1950s to 52 at present, and the rate of migrant and potamic species decreased from 50% in 1950s to 30% at present.

我们以涨渡湖为例开展江湖阻隔后对单个湖泊鱼类资源所产生的生态影响进行研究，结果表明：江湖阻隔导致湖泊生产经营方式改变，使得野生渔业产量的比例由1949年的95%，降低到2002年的不足5%；江湖阻隔后湖泊鱼类种类由50年代约80种下降到现在的52种，其中，洄游性和流水型鱼类比重由50%下降至不足30

The photosynthesis is determined by photosynthesis meterThe results showed that the net photosynthesis rate of Carex lasiocarpa(47.41 μ mol/m/s)is faster than those of other plants in Carex lasiocarpa wetland, Based on the overall sunlight radiation and the efficient photosynthesis radiation, energy utilization rate in radicula was the highest(1.3945% and 3.1879%)While those in spike was the lowest(0.0020% and 0.0046%).

毛果苔草湿地的物理过程观测设在中国科学院三江平原沼泽湿地生态实验站内，用美国CID公司出品的光合仪对典型湿地中几种优势植物的光合能力进行测定；在80℃干燥的植物样品，粉碎后，分别称量约1g左右，用美国公司Parr型氧弹式热量计测定；研究发现毛果苔草湿地建群种中毛果苔草的净光合速率最大，为47.41μmol/m/s。

As a kind of new developing culture phenomenon appearing in consumption-entertainment, network-image era,"spoof" had subverted, solved and removed royal culture freely. It makes the cultural ecological environment that all voices could express themselves more plur.

恶搞作为一种在娱乐消费、网络影像时代下出现的新兴文化现象，以一种自由肆意的文化姿态颠覆、解构了精英文化，使原本就众语喧哗的文化生态环境呈现出更加多元的态势。

She gently rebuff ed him, but agreed that they could be friends
