石油污染对黄河口沉积物工程性质的影响     

王林昌  袁守启  邢可军 《中国海洋大学学报(自然科学版)》2010,40(1)

对黄河口胜利油田某油井附近沉积物进行石油污染状况调查研究,采用坑探试验现场调查污染范围,发现油井沉积物在一定范围内存在石油污染,污染多在0.2～1.5 m深度内,水平距离在140～440 m之间.原位测试污染沉积物强度,取样进行室内石油浓度和沉积物物理力学指标测试.石油污染沉积物物理力学性质与未污染的有较大差别,污染后沉积物的重度、渗透系数和强度等均有所降低.污染后的沉积物结构,多成块状和板状结构.  相似文献

Heavy metals (Cu, Pb, Zn, Mn, Fe, Cr, Ni) in the sediment from Huanghe River Estuary and the adjacent areas were analyzed using Model WFX-IA AAS. The eoneentrationsof these elements are: Cu 9-32ppm,Pb 24-44ppm,Zn 41-105ppm, Mn 500-700ppm, Fe 2.1-3.0%, Cr 50-71ppm, Ni 24-72ppm. There are relatively close correlations among the distribution of the heavy metals, suspended materials and salinity. The distribution of heavy metals in summer are similar to that in winter, except Pb. It is believed that the higher concentration results from the increasing of water discharge,silt content and the decreasing of particle size in the summer. Pb is easily absorbed and carried in the suspended materials,which, perhaps, is another reason that the concentration of Pb is higher in summer.  相似文献

1985年5—6月对黄河口及其邻近海域的27个站进行了大型底栖动物的首航次定量调查。分别对18种环境因子和68个优势种和习见种所做的聚类分析显示了黄河口水下三角洲与邻近海域的某些差异,并联系沉积环境将所研究海域划分为四个区:黄河口水下三角洲、莱州湾、渤海中部和渤海湾东部。对大型底栖动物与沉积速率的关系也做了初步探讨。  相似文献

The Huanghe River is the second largest river in our country. The average annual runoff at the estuary is 44.28 billion cubic meters, the average annual suspended load is 1.12 billion tons, of which 24% was deposited on the delta, 40% on the coast and the rest 36% is considered to be carried into the deep sea by various dynamic factors. We‘ve measured the temperature, salinity, current and suspended load in the estuary from autumn of 1983 to summer of 1984 for building a harbour in future. According to our data and other historical data from some institutes, we‘ve obtained following conclusions: 1) The distribution of temperature in winter is different with from that in summer: the contours of temperature in winter is parallel to coast line,and the contours of temperature in summer is coincident with latitudes. 2) The salinity in summer is lower than that in winter. There are three tongues of low values of salinity at the estuary in summer. They are pointed to North,North-east and South-east respectively. Only two tongues are appeared in winter-northward and south-eastward. 3) The distribution of suspended load is similar to the distribution of salinity,There are three tongues of high values of suspended load at the estuary in summer, they are pointed to North,North-east and Southeast respectively,the quantity of suspended load per litre in winter is much than in summer. 4) The influence of Huanghe River to North area of the estuary is less than to Laichou Bay. 5) The velocities of tide current at the estuary are very large.The maximum value is about 150era/see, and the directions of tide current are parallel to coastline.  相似文献

黄河口及其邻近海域大型底栖动物的初步研究 (一)生物量     

张志南  图立红  于子山 《中国海洋大学学报(自然科学版)》1990,(1)

1985年5-6月对黄河口及其邻近海域的27个站进行了大型底栖动物的首航定量调查。调查海域平均生物量为35.28g/m~2,平均密度为557inds/m~2。棘皮动物占总生物量的47.2％,软体动物占34.2％,多毛类和甲壳类分别占7.5％和6.2％。莱州湾的生物量为调查海域平均生物量的3.5倍。河口输入的营养盐在与高密度低营养盐海水混合过程中,逐渐下沉在莱州湾北部,这是控制该海域高生产力的主要因素。  相似文献

为了阐明黄河口TAlk（总碱度）的行为特征及主要影响因素,根据2004年4月黄河口TAlk实测数据,结合其它化学要素的同步观测资料对其进行了初步探讨.研究结果表明： 黄河口水体在S〈24的区域范围内TAlk呈现出非保守行为,其中 S〈5时TAlk非保守表现为净TAlk的“亏损”, 即水体TAlk低于理论混合TAlk,是由于水体中DIC的沉淀作用引起;在盐度为8～24之间,TAlk非保守表现为净TAlk的“增加”,即水体TAlk高于理论混合TAlk,主要是由于水体中颗粒碳酸盐溶解引起;水体中的CO2参与了颗粒碳酸盐的溶解,并且很可能是影响水体中碳酸盐溶解的主要因素.  相似文献
