This study could deepen the study on estuarine ecosystem and process. It also helped to evaluate S. alterniflora, and to supply scientific foundation of applying S.

在学术上深入理解了河口生态系统的结构和过程，在应用上为互花米草盐沼湿地的评价、湿地生态建设提供依据。

Alterniflora salt marsh presented a trend of increasing gradually from the upper to the lower region of the Yangtze Estuary. 21 species were identified. Assiminea sp., Notomastus latericeus, Cerithidea largillierl, Glauconome chinensi, Gammaridae sp.

2沿着长江河口纵向梯度，互花米草盐沼的大型底栖动物群落的物种数和多样性从上游到下游呈逐渐增多的趋势，丰度主要受到沉积物粒径和互花米草高度的影响。

Either of two herbaceous rushlike bog plants having small yellow flowers and grasslike leaves; north temperate regions.

两种类似灯芯草的沼生植物的任意一种，具有小的黄色花和草状叶；生长于北温带。

The friendly relations between Hunan and Japan can be traced back to over 100 years ago, when China sent around 12,000 students to Japan for cultural exchanges and further study, and among them, one third are Hunanese. And nowadays, Japan is also the country that has granted the most non-reimbursable assistances to Hunan.

中日建交后，湖南与日本各县町关系稳步发展。1983年，湖南省与日本滋贺县因&湖&结缘，缔结了友好省县关系，此后，湖南与日本相继结友好城8对，包括湖南的长沙、湘潭、岳阳、汩罗、醴陵、衡阳、常德、邵阳，日本的鹿儿岛、瑞浪、栗东、沼津等。

Any of several vascular, spore-bearing, aquatic or marsh plants of the genus Isoetes having short rhizomes and quill-like leaves.

水韭一种水韭属的、有维管的、含孢子的水生或沼生的植物，长有短根茎和羽管状的叶子

The results indicated that there was an ecological succession of wetland plant communities and that the successive series is as follows: aquatic plant→helophytes→swampy prata→herbosa with the changes of habitat from aquatic to mesophytic. The horizonal distribution regularity of plant communities showed symmetric distribution at loop lake or banks of small stream and con centric distribution at depression. The vertical distribution regularity is as follows: aquatic vegetation→moor vegetation→swampy prata vegetation→subalpine meadow subalpine shrub from the center of lake to the hilltop.

结果表明，随着湿地水分由多到少的变化，植物群落类型发生相应的生态演替，其演替序列为水生植被→沼生植被→沼泽化草甸植被→草甸植被，且在水平方向呈对列式和同心圆式分布；从湖心至丘顶的垂直分布规律表现为水生植被→沼泽植被→沼泽化草甸→亚高山草甸→亚高山灌丛。

Monorchis belonging to Orchidaceae had a narrower one, indicating that rare and endangered Orchidaceae plants had a less distribution in Beijing mountainous region, and only distributed in several types of forest vegetation communities. Due to the lack of suitable habits, these herbage species were in dire need of prior conservation.

结果表明：野大豆的生态位宽度值较大，为0.297；大花杓兰、沼兰和角盘兰同属于兰科植物，生态位宽度值较小，说明兰科植物在北京地区分布较少，并且仅在几种森林群落类型中有分布，适宜生存的生境较少，急需优先保护。

The problems have been attributed to difficulties in the interpretation of the significance of morphological characteristics used to classify palaemonid shrimp and have hindered the development of stable classification systems.

本研究以中国境内分布的沼虾属种类为主要研究对象，利用DNA测序、PCR-RFLP技术和ISSR技术等分子生物学实验手段，运用支序系统学与分子进化生物学理论及分析方法，以地理群体为基本研究单元，展开从地理种群-物种-属的逐级水平的系统学研究。
