     Therefore, a synthesis investigation on chemical elements of seawater, sediments and biology is carried out on October, 2005, and indices of ocean ecological effects have been observed, comparing with the historical investigation, the accumulative impact is researched in the three sea areas which separated by alkali factory, West Waterbreak and nuclear power plant.

     為此，本研究于2005年10月對連云港近岸海域進(jìn)行了一次綜合性生態(tài)環(huán)境調(diào)查，從海水化學(xué)、沉積物、海洋生物等方面對海洋生態(tài)壓力、生態(tài)效應(yīng)等有關(guān)指標(biāo)進(jìn)行了監(jiān)測，，結(jié)合歷史調(diào)查資料，重點研究了人類開發(fā)活動對堿廠海域、港口海域和核電站海域造成的累積環(huán)境影響，取得了如下研究成果：

     (3) Judging from the research, the sediment rate in Lianyungang area was gradually decreased from south to north, which is the main result of natural environment changed both in time and space, another is the result of human activity to natural environment.

     (3)研究發(fā)現(xiàn)連云港近岸海域的沉積速率從南往北逐漸減小，造成這種現(xiàn)象的一個原因是自然環(huán)境條件的時間和空間變化的結(jié)果，另一個是人類活動對自然環(huán)境干擾的結(jié)果。 研究攔海西大堤內(nèi)側(cè)的柱狀樣，結(jié)果表明在西大堤工程前沉積環(huán)境很穩(wěn)定。

短句來源

     (2) The research indicates that Lianyungang area is the modern underwater shoal, engendering by discard yellow river, sentiment granularity is relatively fine, and mainly consists of silt clay, substance source is relatively single.

     (2)研究發(fā)現(xiàn)連云港近岸海域為南部廢黃河的水下現(xiàn)代堆積淺灘，以粘土質(zhì)粉砂和粉砂質(zhì)粘土為主，物源相對單一。

A finite difference technique is used to construct two-dimensional fixed boundary and varied boundary tidal current numerical models, to culculate the present current field and to predict the current field when the construction of the Xidaba Dam is completed. The fugures of tidal wave, tidal current ellipses, the distribution of maximum current speed, and the current fields at different times are obtained. The tally of computation and observation is good.

采用有限差分解法,建立了連云港近岸海域二維固定邊界和變邊界潮流數(shù)值模型。分別對現(xiàn)狀流場和西大堤建成后的流場進(jìn)行計算和預(yù)測。得出了潮波圖,潮流橢圓圖,最大流速分布和不同時刻的流場圖,計算結(jié)果與實測值吻合良好。

Based on the calculated tidal current in the offshore area of Lianyungang, this paper constructs a Lagrange residual current model and analyzes the change of the Lagrange residual current after the completion of the Xida Dam of Linyungang. Finally, some representative pollutant discharge outlets are selected for numerical tracing.

在連云港近岸海域計算潮流場基礎(chǔ)上建立拉格朗日余流模型,并對連云港市兩大堤建成前后的拉格朗日余流變化進(jìn)行了分析,且選擇有代表性的排污口進(jìn)行了數(shù)值跟蹤。

>=The Lianyungang Harbor is a typical harbor with a muddy embayment in China, and the harbor has suffered from the aggravated siltation in harbor basin since the west breakwater harbor extension project was completed more than 10 years ago. In this paper, the siltation intensity in the harbor basin is calculated based on the observed data and historical data collected in the harbor adjacent sea area, and the sediment load transported by tidal current and the sediment source are also analyzed.

連云港港口是我國一個典型的淤泥質(zhì)海岸上的港口．其擴(kuò)建骨架工程西大堤建成至今已十余年,在這期間港區(qū)的淤積有加重的趨勢,成為港口發(fā)展的隱憂．在連云港近岸海域環(huán)境演變的課題研究和收集前人大量資料的基礎(chǔ)上．計算了港口淤積強(qiáng)度．并對潮流輸沙和泥沙來源做了分析．
