中底栖生物

Consequently, sulphidic bottom waters on continental shelves may be more common than previously believed, and could therefore have an important but as yet neglected effect on benthic communities.

关于硫化物会被亚表层海水中的细菌完全耗尽、从而会被浅层沿海水域的遥感或监测活动忽略的发现表明，大陆架上含硫化物的海底水域也许要比我们所想的更普遍，所以有可能对底栖生物群落产生一个重要的、但以前却被忽略的影响。

The results show that the benthons were not polluted by the heavy metals, but the concentrations of Pb and Cd in crustacea and mollusk were potentially serious. The contents of Cd in crustacea was beyond the Standard Indexes of the seafood. The contents of Cd in mollusk was same as Stan...

结果表明，底栖生物中Hg、Pb、Cd、As含量较低，但甲壳动物和软体动物体内Pb和Cd具有潜在的严重积累问题；甲壳类Cd含量已严重超人体消费标准，软体类的Cd含量等于人体消费标准值，甲壳动物和软体动物的可食性应引起人们的关注。

Based on studies about current development of Methods of separating meiofauna, a new method is advanced in this paper. A suit of device was designed to Separate meiofauna from benthic sediments sample automatically, accurately and efficiently, which based on the technology of Laser-induced Fluorescence Detection, and used other technologies, such as noctilucence, electronics, biophysics, computer, mechanism, and so on. The scheme of macrocosm, the design of light route, the hardware and software design of the photoelectricity detection system and machine control system, the method of signal processing are introduced, especially the hardware and software design and the method of signal processing.

论文分析了目前国内外所使用的小型底栖生物分离方法现状，并以此为基础，自主开发了一套基于激光诱导荧光技术，并且集荧光化学技术、电子物理技术、光电测量技术、计算机技术及机械技术为一体的小型底栖生物标本自动分离系统，实现了从沉积物样品中自动分离小型底栖生物标本，从而大幅度提高室内小型底栖生物分样的工作效率和精度的目的，并以此完成了大洋协会"十五"攻关项目："小型底栖生物标本自动分离系统研制"。

Benthic algae bloomed from January to March in the oyster bed were not observed in the control area 500m away which had similar bottom soil composition. Polychaetes were more abundant than crustacean gastropods and other large benthic fauna the year round and showed a marked increase during the winter.

在研究过稗中首次发现底滚在牡蛎床下 9～14 公尺深之海底繁生(1月～3月)，以丝状矽藻及Navicula 属占优势，但是在无牡蛎床之对照区却无底藻繁生，底栖生物以多毛类占优势，在底藻繁生时有明显增加之量，春季时有 fauna development 之现象。

The senate abalone grows seedlings the antibiotic research Abstract: The trepang the abalone is north part of our country the important bottom roosts the biological resources, has the very high economic value, also is a present prestige mirage item of important aquatic product increased reproduction production project.

参鲍鱼育苗中桡足类抗药性的研究摘要：海参鲍鱼是我国北方重要的底栖生物资源，具有很高的经济价值，也是目前威海市的一项重要的水产增养殖生产项目。

The research indicate that the aquatic ecosystem of Wuhan city lakes now is: elementary production and consumption keep high amount, and accumulate in the water bodies, then the benthon ,so much as fish's community to decline seriously, cause the main nutrients cycle and energy circulation in the system is obstructed, that means the "elementary production-elementary consumption-advanced consumption" replaced by the "elementary production-elementary consumption-analyze by itself – reproduction", this circulation of the the nutrients is unfavorable to the system.

生态系统结构研究表明武汉市湖泊水生生态系统目前所处状态：初级生产和初级消费维持较高生产量和现存量，在水体中积累，而较高层次的底栖生物乃致鱼类群落严重衰退，导致系统中主要物质和能量循环：初级生产—初级消费—高级消费受阻，代之而起的是初级生产、初级消费—自行分解—再生产的循环，不利于系统中物质转移。

Chemical analysis and toxic tests were combined with benthic macro invertebrates community structure alternations. Based on tri-axial graphs together with relevant matrix of decision-making, the initial bio-responsive sediment quality criteria clearly indicated the situation of heavy metal pollution, and showed the dose-response relationships between heavy metal contamination and benthic biotics. Moreover, the SQC may provide some basic material for establishment of sediment quality standards and for follow-up remediation engineering in the area.

通过将化学分析、毒性鉴定和底栖群落结构变化三基元集成为一体的三轴图和相应的响应信息判断矩阵，基于现场生物响应的沉积物质量基准能较为清晰地指示乐安江流域表层沉积物中重金属污染的相对程度和分布模式，体现底栖生物对沉积物重金属污染的剂量-响应关系，为进一步制订该区域沉积质量管理标准、开展后续的污染治理与恢复工程提供技术保证和科学依据

Through field observations and sampling, by referencing to other documents and information, with correlation analysis and principal component analysis as mathematical tools, we know that: the distribution of the number of birds has close relations with density of zoobenthos and ratio of water area, the correlation coefficient of the distribution and the two factors are 0.916 and 0.745, the density of zoobenthos is the most direct reflection; Vegetation types , the coverage and water level may have relations with the distribution of the kind of birds, normally, middle and large volume birds need high vegetation and high coverage as their habitats, and waterfowl like deep water as their habitats; Human activities have low impact on the the distribution of the number of birds, but the activities have relations with all the other environmental factors.

通过实地的观测、采样，并结合其他文献的资料，以相关分析和主成分分析作为数学工具，得知：鸟类的数量分布和底栖生物密度、水域面积比例有着密切关系，鸟类数量分布与两者的相关系数分别为0.916和0.745，其中，底栖生物密度是鸟类数量分布的最直接反映；植被类型、植被盖度和水位可能与鸟类的种类分布有一定关系，通常体积中、大型的鸟类需要较高的植被高度，来作为自己的栖息场所，水禽需要水位较深的区域作为自己的栖息场所；人为活动对鸟类数量分布的影响不大，但对所有自然环境因子都有一定影响。

Separating meiofauna from benthic sediments sample is one of pivotal steps of the quantificational research of meiofauna.
