Abstract:
在中国的 Seagrass 研究仍然在它的幼年期。尽管最近有进步，仍然有很多研究，需要获得 seagrass 的更好的理解。在这篇文章，我们从二个方面在中国在 seagrass 研究考察并且讨论进展：(1 ) seagrass 种类和他们的分发；(2 ) 在中国的 seagrass 研究包括他们的分类上的研究，生态学，光合作用，在水产业的应用，咸忍耐的机制和其它研究话题。属于 8 个类的 18 seagrass 种类的一个总数在中国(包括的香港和台湾) 在九个省和区域被散布，以及 Xisha 和 Nansha 群岛。他们能被划分成二个组：一个诺思中国组和一个华南组。基于 seagrass 分发，中国大陆海岸能被划分成三节：诺思中国 Seagrass 海岸，中间的中国 Seagrass 海岸，和华南 Seagrass 海岸。生态的研究在山东，广东， Guangxi，和海南的关键区域在 seagrass 社区，在 seagrass 生态系统骑车的营养素，基因差异，污染生态学和研究上包括研究。在关键区域的 Seagrass 种类和他们的地点，社区结构，生态的评估，附生植物，生态的功能和威胁也被总结。另外的研究集中了于 seagrass，中国的威胁的 seagrass 种类，和 Halophila ovalis 的花粉形态学的遥感。关键词 seagrass - seagrass 草地 - 海洋的生态系统 n ] Guangxi 科学基础(号码 0832030 ) 支持的中国， Guangxi 大学(2008 ) 的科学研究资金， UNDP/GEF/SCCBD 工程(SCCBD/CPR/02/31 ) 和 Guangxi 给实验室资金(号码 07109007 ) 调音Cite
The flora and ecological distributions of tropical seagrasses were investigated in Nagura Bay, Ishigaki Island, okinawa. Seagrass meadows in the Bay are developed along the coast, their areal extensions wide at the inner part and narrow at the outer part of the bay. Six genera, eight species of seagrasses, Zostera japonica, Halodule uninervis, H. pinifolia, Syringodium isoetifolium, Cymodocea rotundata, C. serrulata, Thalassia hemprichii, and Halophila ovalis are found there. Ecological distribution of seagrasses are analyzed for their habitat utilization, mainly from the view point of vertical range, horizontal situation in the bay, areal extent of distribution and dominance in biomass. Thalassia hemprichii is the most common species in upper sublittoral zone and becomes dominant at various habitat situations. Though there are some degree of overlap, species pairs of Halodule and Cymodocea exhibit considerable difference in habitat utilization within each congeneric species pair. Zostera japonica, Syringodium isoetifolium and Halophila ovalis grow at limited habitat conditions, respectively. Several species jointly appeard in most sampling localities, three types of associations such as Halodule pinifolia-Halophila ovalis association, T.hemprichii-C. rotundata association and T.hemp-richii-C. serrulata association, are recognized.

II. Faunal components Fonseca MS, Meyer DL, Hall MO In this paper we report on changes in shrimp, fish and crab abundance, composition and size in planted Halodulewrightii and Syringodiumfiliforme beds as compared to unvegetated, and natural, H. wrightii, S. filiforme, and Thalassiatestudinum habitats in Tampa Bay, Florida, USA, over a 3 yr period (1987 to 1990). Using a gear type selective for small resident macroepibenthic fauna (1 m^(2) dropnets), we found that in 1.8 yr H. wrightii planted on 0.5 m centers developed an animal density, number of taxa, and species composition equivalent to that found in natural beds. Animals tended to be larger in planted beds over the course of the study. Comparison of planted S. filiforme and mixed H. wrightii and S. filiforme with natural beds was impaired due to failure of several planting areas but exhibited a pattern of development similar in some ways to that of planted H. wrightii. Macroepibenthic animal density in planted beds displayed an asymptotic relationship with areal shoot density, where animal densities became equal to natural beds at shoot densities only a third of the average density for natural beds. This pattern corroborates the existence of threshold values of habitat structurein seagrass beds influencing numerical abundance of some associated animal communities. Macroepibenthic faunal abundance and composition in planted beds could be inferred from the amount of areal coverage of seagrass and its persistence over time, while measurement of areal shoot density may provide an important first check point on the road to functional restoration of seagrass habitat.

The present research seeks an appropriate method of monitoring both submerged and exposed seagrasses. A seagrass mapping technique was developed using combination data sets from satellite images, digital maps, SONAR imagery and handheld-GPS data collected from seagrass meadows (Zostera marina) at Shinkawa–Kasugagawa estuary, the Seto Inland Sea, Japan, in September 2011. The entire coverage area of 123,000 m2 was calculated from 638 captured SONAR images. Zostera meadows were observed at water depths of 1.6–5.0 m, over sandy sediments. Zostera was not found at water depths greater than 5.0 m, where the sediments are muddy. The canopy height of Z. marina was estimated to vary between 14 and 87 cm. Additional mapping of intertidal seagrass meadows of Halodule pinifolia was also carried out in Rayong Province, Thailand, by GPS tracking during April 2009 and December 2010. Coverage areas varied between 33,498 and 76,207 m2, and the highest coverage area was found in April 2009. The present study demonstrates that the entire area of both submerged and exposed seagrass meadows can be calculated by simple methods in a short time with acceptable accuracy.
