黄戚民  周时强 《台湾海峡》1996,15(3):305-309

福建红树林上的钻孔动物共发现了５种，其中软体动物的龙骨节铠船蛆Ｂａｎｋｉａ ｃａｒｉｎａｔａ、裂铠船蛆Ｔｅｒｅｄｏ ｍａｎｎｉ和甲壳动物的光背团水虱Ｓｐｈａｅｒｏｍａ ｒｅｔｒｏｌａｅｖｉｓ是破坏红树林的主要的钻孔动物。钻孔动物钻凿红树茎的基部和裸露的根部，垂直分布受潮汐水位制约，在红树林区的纵深分布与水流畅通程度有关。  相似文献   

南麂海域台风影响过程中的波浪特征     

黄树生 《海洋湖沼通报》1996,(1):1-8

根据１９８３－１９８９年南麂海洋站在台风影响过程中的实测风和浪资料，分析了该海域的波浪特征。结果表明，这个海域的台风波浪通常是混合浪，在台风影响过程中出现的最大值波高，既有较大波陡的风浪，也有波陡较小的清浪；各向波高的均值变化不大，各向最大波高却有较大幅度的差距；本区的台风浪以４级波高占优，风浪以ＮＮＥ向、涌浪以Ｅ向为常浪向；波高为４级的风浪和涌浪，其周期分别在４．０－４．９Ｓ和７．０－７．９Ｓ之  相似文献

Sublittoral meiofauna with particular reference to nematodes in the southern Yellow Sea, China   总被引：6，自引：0，他引：6  

Xiao-Shou Liu  Zhi-Nan Zhang  Yong Huang   《Estuarine, Coastal and Shelf Science》2007,71(3-4):616-628

Densities of major meiofaunal taxa were investigated at 34 sampling stations during six cruises by R/V Beidou to the southern Yellow Sea, China from 2000 to 2004, and the community structure of free-living marine nematodes was studied during one of the cruises in 2003. Meiofauna abundance ranged from 487.4 to 1655.3 individuals per 10 cm². Nematodes and harpacticoid copepods were the two most dominant groups, contributing 73.8–92.8% and 3.5–18.7%, respectively, to the total meiofauna abundance. One-way ANOVA showed no significant annual fluctuation of meiofauna and nematode abundances from 2000 to 2004 in the southern Yellow Sea. However, two-way ANOVA based on six stations sampled in 4 years (2001–2004) showed that there were significant differences among the six stations and the 4 sampling years for meiofauna, nematode and copepod abundance. Correlation analysis demonstrated that meiofauna abundance was mainly linked to chloroplastic pigments. Other environmental factors could not be ruled out, however. A total of 232 free-living marine nematode species, belonging to 149 genera, 35 families and 4 orders, were identified. The dominant species in the sampling area were the following: Dorylaimopsis rabalaisi, Microlaimus sp.1, Prochromadorella sp., Promonohystera sp., Cobbia sp.1, Daptonema sp.1, Leptolaimus sp.1, Halalaimus sp.2, Aegialoalaimus sp., Chromadorita sp., Parodontophora marina, Parasphaerolaimus paradoxus, Quadricoma sp.1, Campylaimus sp.1, Halalaimus gracilis, Paramesacanthion sp.1, Paramonohystera sp.1, and Metalinhomoeus longiseta. CLUSTER and SIMPROF analyses revealed three main types of nematode community (or station groups) in the sampling area, including I: coastal community, II: transitory community between coastal and YSCWM (Yellow Sea Cold Water Mass), and III: YSCWM community. Each community was indicated by a number of dominant nematode species. Bio-Env correlation analysis between the nematode community and environmental variables showed that water depth, sediment water content, organic matter, chlorophyll a (Chl-a) and phaeophorbide a (Pha-a) were the most important factors to determine the community structure.  相似文献   

沉积物镁铝含量比及其古气候意义   总被引：3，自引：2，他引：3  

张士三  陈承惠 《台湾海峡》1993,12(3):266-271

沉积物的镁铝含量比——m 值(m=100×MgO/Al_2O_3)与沉积水介质的盐度、pH 水温关系密切。当水温处在冰点以下时,沉积物的m 值随水温降低而增大。当水温处在冰点以上时,水介质的盐度、pH 和水温的增加,都有利于m 值增大。由于气候条件能直接或间接地影响沉积水介质的特征,因此,沉积物的m 值对古气候的变化具有一定的判别功能。通过对中国元古宙以来沉积物m 值的分析,发现古气候的热冷变化有1200Ma 的周期,其中还有次一级的热冷气候波动。第四纪的气候是处在热气候期后期的一个冷的气候波动阶段。  相似文献   

Carbonate and organic carbon sedimentation on the continental margin off Southeastern Taiwan     

Der-Duen Sheu  Chi-Yue Huang 《Geo-Marine Letters》1989,9(1):45-51

Sediment and porewater data of two sediment cores from offshore southeastern Taiwan show important effects of the complex sea floor topography upon carbonate and organic carbon deposition. The variations in carbonate and organic carbon contents are attributed to the effects of carbonate compensation depths, glacial-interglacial history, and condition of anoxia. The study is of significance for environmental reconstruction and petroleum source bed evaluation of ancient analogues.  相似文献

Holocene strata along the coastal area of eastern Guangdong     

Li Pingri  Huang Zhenguo  Zhang Zhongying  Zong Yongqiang 《海洋学报(英文版)》1988,7(1):104-114

The data of about 1700 drill holes are correlated, of which 47 drill sections are discussed comprehensively for chronology and sedimentology, and the characteristics and changes of sporo-pollen are analysed. The authors consider that the Holocene strata along the coast of eastern Guangdong can be divided into five formations. The Holocene began 12 000 years ago; the fluvial facies gravel, the striped weathered clay and the "old red sand" serves as the boundary between the Holocene and the Pleistocene.  相似文献   

南海大气低层风场的气候特征分析     

黄志兴  刘嘉玲 《热带海洋学报》1995,(4)

分析１９８０－１９８７年欧洲中长期预报中心（ＥＣＭＷＦ）每日风场、温度场格点资料及同期南海区域测站和船舶资料，讨论南海低层风场的气候特征。南海为典型的季风活动区，冬季盛行东北季风，夏季盛行西南季风。流场的季节转换表现为季风系统的交替，相应不同的季风系统，南北温度梯度有一逆转过程，南海北部是温度梯度大且发生明显逆转的海区。１２°Ｎ以南海区气温全年变化极小，整个海区大气温度的季节变化不如流场变化快和显著。  相似文献
