求高手帮忙！！

The total biomass of the inter-tidal zone has different distributions in different substrate coasts of Zhoushan Archipelago.In all sampling sites of this investigation.the biorrrass in the left of the clock on A1ia0}Zhil1u Isldiul(LDM)with rocky Shor is highest.and that in the teft of Yangmeikeng on Dachangtu Island (LYM) with rocky shore and Wanbei bank on Qushan Island (WB) with muddy shore is second. Thus it can be seen that the distributions of the biomass of Zboushan sea areas are non-homogeneous very much, and the biomass of the inter-tidal zones of the different habitats have great difference from each other. This may be because of the double inter-factions between the ecological factors and human activities. In relative hidden area,the left of the 'dock on Miaozhihu Island (LDM), owing to high salinity, good sea water, and violent storm, its biomass is very high and achieves 18 664.16 g/m2, and this inter-tidal zone mainly adapt Mytilus eduAs L and
Tetraclita japonica Pilsbry ete to survive. The outlet of the water channel on Xiaochangtu Island (OW X) is open, but its storm has little impact force, so its biomass is still higher and reach to 1340.64 g/mz. However, in Zhoushan island, although there is violent storm and open, yet its biomass is generally lower, such as in open Ximatou on Zhoushan IsaInd(XMT), relative open Zhengang on Zhoushan Isalnd (ZG) and Tangtou on Zhoushan Isalnd (TT), their biomass is 488.16,27.68 and 452.16 g/m2, respectively. The biological quantity of the inter-tidal zone of Zhoushan Archipelago in the investigation has obviously descended compared with that reported in 1990's. The inherent reasons why the species quantity decreased in 10 years need further research.

Answer 1

总生物量的潮间带不同分布在不同的衬底海岸舟山Archipelago.In所有采样点的investigation.the biorrrass在左侧的时钟A1ia0 ） Zhil1u Isldiul （的LDM ）与岩石绍尔是最高的。并在teft的Yangmeikeng对Dachangtu岛（淋巴）与岩岸和皖北银行Qushan岛（世行）与泥质海岸是第二次。因此可以看出，分布的生物量Zboushan海域是非均匀，非常和生物量的潮间带不同生境有很大的差异对方。这可能是因为双跨派系之间的生态因素和人类活动。相对隐蔽区，左边的'码头Miaozhihu岛（的LDM ） ，由于高矿化度，良好的海水，和强烈的暴风雨，其生物量非常高，达到18 664.16克，这潮间带主要适应紫eduAs L和
日本笠藤壶Pilsbry埃泰生存。出口水通道Xiaochangtu岛（超重x ）是开放的，但它的风暴的影响力不大，因此它的生物量仍然较高，达到一千三百四十〇点六四克/生子。然而，在舟山岛，虽然也有强烈的暴风雨和开放，但其生物量普遍较低，如开放Ximatou舟山IsaInd （物XMT ） ，相对开放岗舟山Isalnd （ ZG ）和塘头舟山Isalnd网站（ TT ） ，其生物量是488.16,27.68和452.16克，分别。生物量的潮间带的舟山群岛中的调查已明显下降，与1990年报告的。的内在原因，物种数量下降， 10年需要进一步研究。
