Also, the 121 angiosperm plant species was attributed to 55 families and 93 genus. There was only one gymnosperm plant species.

The evolutionary relationships were investgated by comparing the results from molecular data alone or molecular data combined morphological characters using different analysis methods: maximum parsimony by PAUP(superscript *) 4.0 and Bayesian inference by MrBayes 3.0B4. Base composition and ti/tv of 28S rDNA D2 regions were analyzed by PAUP(superscript *) 4.0. The results showed that GC content of the 28S rDNA D2 gene sequences of subfamily Euphorinae ranges from 40.00% to 49.25%. Transversion frequency of sequence variable sites among species of Euphorinae was higher than that of transition. The subfamily Euphorinae was proved to be a paraphyletic group with close relationship to subfamilies Neoneurinae and Cenocoelinae; only two tribes, Meterorini and Microctonini, were proved to be monophyletic groups; Centistini, Cosmophorini, Euphorini and Dinocampini were paraphyletic groups; the basal position of tribe Meterorini within Euphorinae was partially supported by our phylogenetic trees, and tribe Microctonini was proved to be a group at the top of the trees.

结果表明：优茧蜂亚科的28S rDNA D2基因序列片段的GC%含量在40.00%~49.25%之间变动，而对于碱基替代情况来讲，优茧蜂亚科各个成员间序列变异位点上颠换大于转换；不同的分析和算法所产生的系统发育树都表明目前根据形态定义出的优茧蜂亚科Euphorinae不是一个单系群，而是一个与蚁茧蜂亚科Neoneurinae和高腹茧蜂亚科Cenocoelinae混杂在一起的并系群；在优茧蜂亚科内部，悬茧蜂族Meterorini和食甲茧蜂族Microctonini（排除猎户茧蜂属Orionis）为单系群，而宽鞘茧蜂族Centistini、大颚茧蜂族Cosmophorini、优茧蜂族Euphorini、瓢虫茧蜂族Dinocampini为并系群；悬茧蜂族Meterorini在优茧蜂亚科Euphorinae内位于基部位置的观点得到部分的支持，同时食甲茧蜂族Microctonini被判定为相对进化的类群。

ReMV causes necrotic lesions on hosts such as Nicotiana glutinosa, Nicotiana rustica, Datura stramonium, Chenopodium quinoa, Chenopodium amaranticolor and Tetragonia expansa and causes systemic mosaic on hosts such as Nicotiana tabacum L, Nicotiana tobacum CV. K326, Lycoporsicon .esculentum and Brassica pekinensis.

对ReMV在寄主植物上的症状表现进行了测定，结果表明，ReMV可以侵染茄科、番杏科、十字花科和藜科等4科10种植物，其中在茄科的心叶烟、黄花烟、蔓陀罗；番杏科的番杏；藜科的苋色藜和昆诺藜上表现为局部枯斑症状。

One of four subclasses or superorders of Monocotyledones; comprises 17 families including: Liliaceae; Alliaceae; Amaryllidaceae; Iridaceae; Orchidaceae; Trilliaceae.

单子叶植物总目的4个亚纲之一；由17个科组成；包含百合科；葱科；石蒜科；鳶尾科；兰科；延龄草科。

There were 203 avian species in Dazhanhe Nature Reserve, of which 92 Asseriformes species and 110 non-Asseriformes species were found, and composed mainly of Muscicapidae, Anatidae and Scolopacidae.

结果表明：大沾河自然保护区共有鸟类16目39科203种，其中雀形目鸟类16科92种，非雀形目鸟类111种，种类较多的科有鹅科、雀科、鸭科、鹬科等。

However, our study on the phylogenetic relationship among the Accipitridae, Ardeidae, Estrildidae and Corvidae, Caprimulgidae, and Strigidae and Tytonidae, the results did not support Sibley's viewpoint which conbined Falcoiformes

通过分析隼形目鹰科与鹳形目鹭科、雀形目梅花雀科和鸦科、夜鹰目夜鹰科和鸮形目鸱鸮科和草鸮科的系统进化关系，得出的结论也不支持Sibley等依照DNA-DNA杂交研究结果将隼形目并入鹳形目的观点。

They are Onagraceae, Iridaceae, Salicaceae, Chenopodiaceae, Polygonaceae, Cyperaceae and Asteraceae.

它们分别是：柳叶菜科、鸢尾科、杨柳科、藜科、蓼科、莎草科和紫菀科。

In habitats of the broad-leaved forest, the dominant tree are the species of Fagaceae in tree layer, Theaceae, Saxifragaceae and Lauraceae in shrub layer, Cyperaceae, Dryopteris spp. and Liliaceae in herb layer.

在阔叶林型栖息地中，乔木层主要树种为壳斗科植物，灌木层植物以山茶科、虎耳草科和樟科等科的种类为主，草本层植物以莎草科、蕨类和百合科为主。

The results showed:(1)The flora of community is rich and complex,and it belongs to the transitional zone for many genera,the subtropical-temperate zone geographical composition of genera are dominant,about 51.47% of the total genera,and there are characteristics which form subtropical to temperate zone transition.(2)The species are mostly composed of Fagaceae,Lauraceae,Anacardiacea...

结果表明(1)该群落区系组成比较丰富和复杂，属于许多属的过渡地带，具有从亚热带向温带过渡的特征；(2)种类组成以壳斗科、樟科、漆树科、卫矛科、榆科、五加科、金缕梅科等为主，但优势种、建群种以温带属为主；(3)种群生活型谱以高位芽占绝对优势，群落垂直结构明显。

The taxonomic system is very different from the one used widespreadly by foreign scholars.

但此分类系统与国外所用的分类系统差别较大，争论的焦点在于斑腿蝗科、剑角蝗科、斑翅蝗科、网翅蝗科和槌角蝗科5个科的分类地位及其相互关系，因此我们从分子水平上探讨这5科的系统发育关系，为完善蝗总科分类系统提供一些必要的证据。
