植物区系

The geographical compositions of herbaceous plants of shrub-grass plot's soil seed bank indicate that genera of cosmopolitan have a heavy percentage, and indicate furthermore that the growth of herbaceous layer is affected significantly by human being's activities, and many calcifuge plants and indifferent plants in herbaceous layer reflect in certain extent that floristic element and ecological types are intricate.

各样地灌草坡种子库草本植物的地理成分表明世界分布属占较大比重，表明草本层的发育受人为活动的影响较为明显；且草本层中的厌钙植物和随遇植物也较多，从一个侧面反映了在人为活动的干扰影响下区系成分和生态类型的混杂。

The research scopes include plant taxonomy, floristics and biogeography, the origins and phylogenies of higher plants, population biology and conservation genetics, Evo-Devo and evolutionary genomics.

In this paper, three kinds of dispersed cordaitean cuticles are described in detail from the Permian coal_bearing strata in China.

本文较详细地描述了 3种产自中国华夏植物区二叠纪煤系地层中的科达植物分散角质层。

The 134 genera of vascular plants had 14 areal-types, including 42 cosmopolitans 55 temperate types 30 tropic types 2 Mediterranean-types, 2 East Asia types and 1 endemic species. The cosmopolitan and temperate type accounted for 31.34% and 41.04% of all the genera, respectively revealing the azonal feature of the wetland vegetations and the influences of cold and wet climate on the formation and distribution of the vegetations.

维管束植物属有14个地理分布区类型，包括世界分布属42属、温带分布属55属、热带分布属30属、古地中海属2属、东亚分布属4属、中国特有分布属1属，其中世界分布属和温带分布属分别占区系维管束植物总属数的比例较高，分别为31.34%和41.04%反映了湿地植被的隐域性和冷湿气候对湿地植被发育、分布的影响。

One hundred and fifteen species were identified, among which coastal eurythermic species were predominant, showing obvious characteristics of subtropical population fauna. The results showed that the average abundance of phytoplankton in Shacheng Harbour was 3113.24 ind·L-1. The abundance was higher in the inner bay than that in the outer bay in horizontal distribution. The surface abundance was a little higher, but there was no significant gradient in different water layers in vertical distribution. Shannon-Wiener diversity index, Margalef richness index, Pielou evenness index and Simpson dominance index were 2.390, 2.650, 0.726 and 0.306, respectively.

结果表明，该次调查共出现浮游植物115种，种类以沿岸广温广盐性种为主，并呈现较为明显的亚热带海湾种群区系特征，浮游植物的平均丰度为3 113.24 ind·L-1；水平分布上，呈内湾高于外湾的格局；垂直分布上，表层丰度略高，不同水层的分布梯度不明显；Shannon-Wiener多样性指数、Margalef丰富度指数、Pielou均匀度指数和Simpson优势度指数分别为2.390、2.650、0.726、0.306。

Some proposals for protecting the resource of the rare and endanged plants are put forward on basis of geographical distribution and floristic f...

To accumulate basically materials of the medicinal plants from Lamiaceae in Henan, and provide data for its utilization, conservation, artificial reproduction and enlarging population of wild resources, The germplasm resource and floristic phgtogeographical features of medicinal plants from lamiaceae in Henan are analyzed by conducting field investigation and consulting specimens and related data.

为了积累河南省唇形科药用植物资源的基础资料，以便为其野生资源的开发利用、保护以及引种驯化提供科学依据，此次研究采用野外踏查、室内查对腊叶标本和校对相关文献资料的方法，对河南省唇形科药用植物种质资源及其区系特点进行了初步的研究和探讨。

Meanwhile, tree species in the upper canopy layer were more stable than that in the lower layers of the fragmented forest.

与连续森林比较，片断热带雨林的植物物种丰富度和物种多样性指数都比较低，而且有相当低比例的大高位芽、中高位芽和附生等生活型植物，而藤本、小高位芽和矮高位芽等生活型植物的比例则较高；泛热带、热带亚洲至热带非洲的区系成分比例较高，而当地成分则减少；群落的上层树木比下层树木更加稳定。

Haba Lake a total area of 16 million hectares of vegetation in tourist areas in the District Department of the Eurasian steppe region is, the central Asian region, China's Loess Plateau, Inner Mongolia Prairie Provinces Prairie Provinces to the transition zone, protected areas are known to all kinds of 507 kinds of plants, a variety of terrestrial animals, 149 kinds.

哈巴湖总面积16万公顷，旅游区的植被在区系上属欧亚草原区，亚州中部地区，中国黄土高原草原省至内蒙古草原省过渡地带，保护区内已知各类植物507种，各种陆生动物149种。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
