Established in 1985, the original mission of the center was to study the impacts of nonindigenous species in the U.S., to restore imperiled freshwater and estuarine species, and restore anadromous fish populations.

该中心始建于1985年，其最初的任务是研究非本土鱼类在美国的影响，恢复受到威胁的淡水和河口物种，恢复溯河性鱼类种群。

Based on the unique characteristics of the Yellow River and previous research on its ecological water requirement, the present paper recommends that the water requirement for transport in the flood season and base ecological flow in non-flood season should be both included in the ecological water requirement. The water requirement for transport is 80 × 108-120 × 108 m3 per year if the bankfull discharge carries the largest sediment and contaminant load over a long period of time. The base ecological flows in non-flood season at Huayuankou and Lijin stations are 80 × 108-100×108 m3 and 50 × 108-60 × 108 m3, respectively.

通过分析黄河下游1958～2000年实测生态可用水，探讨生态需水量内涵，根据黄河特殊性及黄河生态需水量的研究现状，将维持和保护河流功能的黄河下游生态需水量分为汛期输运水量和非汛期生态基流量，在平滩流量输运能力最强的前提下，估算黄河下游汛期输运水量为80～120亿m3，根据实测资料估算作为黄河下游水量控制断面花园口水文站和作为河口地区水量控制断面利津水文站的非汛期生态基分别为80～100亿m3和50～60亿m3。

The seismic facies study indicates that the developed structures include prograding configuration, rhythm-inverted distributary mouth bar on braided delta front and turbidite in bathyal lake mud, belonging to typical braided delta system.

根据沉积背景和沉积环境标志的研究，发现阿南地区存在多个煤层、发育直立的植物根茎化石和泥裂构造，地震相中前积结构发育，前缘相中反韵律的分流河口砂坝发育，在半深湖泥岩中浊积岩发育，属典型的辫状河三角洲沉积体系。

Besides Copepoda, Medusae, Cladocera, Mysidacea also played an important role in maintaining the structure and function of estuarine ecosystem.

除桡足类之外，水母类、枝角类、糠虾类等其它浮游动物在维持河口生态系统结构与功能上也具有重要作用。

Copepoda was dominant group in zooplankton of the Changjiang Estuary. The abundance of them overwhelming dominated all zooplankton.

三、桡足类是长江河口浮游动物中的优势类群，其数量分别在枯、丰水期浮游动物总数量中占绝对优势。

A one-year investigation on the N and P concentration and accumulation of Cyperus malaccensis in the wetlands of Minjiang River estuary showed that the N and P concentration of C.
