胶州湾某海域海水水质和沉积物现状调查与评价

胶州湾西海岸跨海大桥与黄山嘴之间沿岸海域,pH、DO、COD、石油类、无机氮、汞、镉、砷、铜、锌在全部21个站位均符合二类海水水质标准,铅和镍均超出二类海水水质标准,活性磷酸盐和硫化物在部分站位不符合二类海水水质标准。小潮期间11个沉积物调查站位的沉积物样品中石油类,汞,砷,铜,铅,锌,镉均符合一类沉积物标准。大潮期间7个沉积物调查站位的沉积物样品中硫化物含量均符合一类沉积物标准。     

胶州湾女姑口海域大型底栖动物群落特征与生态健康评价

为探究青岛胶州湾女姑口海域大型底栖动物群落特征,并对该海域进行底栖生态评价,2018年11月与2019年4月于胶州湾女姑口潮下带海域设置12个调查站位,开展大型底栖动物与环境要素调查。秋、春两个航次共检出大型底栖动物82种,其中环节动物多毛类29种、节肢动物甲壳类29种、软体动物18种,这3个门类种类数占总种类数的92.68%;大型底栖动物平均生物密度665.83 ind./m²,平均生物量358.65 g/m²,平均Shannon-Wiener多样性指数为2.77。两个航次均表现出明显优势的种为寡鳃齿吻沙蚕(Nephtys oligobranchia)、寡节甘吻沙蚕(Glycinde gurjanovae)和菲律宾蛤仔(Ruditapes philippinarum),其次为小型贝类及多毛类,优势物种表现出小型化趋势。基于栖息密度进行典范对应分析(CCA)表明,盐度、水温是影响大型底栖动物分布特征的主要因子。大型底栖动物群落的Shannon-Wiener多样性指数、AZTI海洋生物指数(AMBI)及多变量AMBI (M-AMBI) 分析显示,胶州湾女姑口海域底栖生态系统受到一定程度的干扰。     

黄海西岸胶州湾至海州湾段全新世海岸变迁

根据海蚀、海积地貌特征，分析了黄海西岸海州湾到胶州湾这段岸全新世以来的海岸变迁过程，认为该区中全新世曾出现过高于现代海平面１．５米左右的高海面。     

胶州湾北部水域浮游植物研究Ⅰ——种类组成和数量变化

根据1995年3月至1996年1月胶州湾北部水域调查资料，对调查区浮游植物种类组成、细胞数量、优势种组成和季节变化进行了分析研究，并与历史资料进行了比较。结果表明，浮游植物主要由硅、甲藻组成，其中硅藻在细胞数量和种类上都占优势；浮游植物细胞数量平面分布的总趋势依月份而异；季节变化属双周期类型：高峰期出现在1月和9月，低谷期出现于5月和11月；与历史资料不同的是，网采浮游植物的种类和细胞数量都呈现出不同程度的下降趋势。     

Matrix-bound phosphine: A new form of phosphorus found in sediment of Jiaozhou Bay

Matrix-bound phosphine (PH3),a new form of phosphorus,was found in sediment of Jiaozhou Bay in December 2001,Concentration and distribution of PH3 in different layers of sediment with different stations were analyzed.The results show that PH3 concentrations are various with different layers and different stations.PH3 concentrations in the bottom layer of sediment (20-30 cm) are usually higher than those in the surface layer (0-4cm) ,The highest PH3 concentration in our investigation reaches 685 ng/kg (dry),which is much higher than those in terrestrial paddy soil ,marsh and landfill that have been reported up to now,The correlation analysis indicates that there is no apparent correlation between the concentrations of PH3 and inorganic phosphorus in sediment.However,the correlation between the concentrations of phosphine and organic phosphorus in the bottom layer of sediment is remarkable (R^2=0.83).It is considered that PH3 in sediment of Jiaozhou Bay is mainly produced from the decomposition of organic phosphorus in the anaerobic condition,and so PH3 concentrations are related to organic phosphorus concentration and anaerobic environment in sediment,The discovery of PH3 in sediment will give people some new ideas on the mechanisms of phosphorus supplement and biogeochemical cycle in Jiaozhou Bay.     

胶州湾悬浮体特性及其对水动力和排污的响应

2001年8月在胶州湾西南部进行了连续的定点水样采集和一周的潮流流速大小、流向、水位和浊度观测. 发现: (1) 悬浮物中非矿物组分含量平均达87%, 明显高于以矿物颗粒占优势的高浊度海湾. (2) 总体上, 悬浮物的粒径呈表层水样>近底层水样>底质, 趋势同高浊度环境相反. (3) 平静天气下, 悬浮颗粒物浓度具有明显的涨、落潮和大、小潮周期变化; 但强风天气可以打破这种格局. (4) 观测点(20 m水深) 悬浮物浓度的变化在近底层受沉降-再悬浮作用控制, 但在表层受平流作用制约, 后者反映垂向交换不够充分. 结论: 低浊度海湾悬浮颗粒物的成分和粒径组成易受沿岸污染物输入的影响; 悬沙来源少、波浪和流速小、排污控制是维持海湾低浊度的重要机制.     

Suspended particulate matter in Jiaozhou Bay： Properties and variations in response to hydrodynamics and pollution

Based on water samples collected and observations of currents, tidal levels as well as turbidities taken, respectively over a period of 15 and 7 d, in southwestern Jiaozhou Bay on August, 2001, it was found that: ( i ) the average content of non mineral component amounted to 87% of the suspended sediment matter (SPM) in Jiaozhou Bay,much higher than in estuaries and bays where turbidity is high and mineral particulates dominates; (ii) in contrast to high turbid bays, SPM was generally coarser than bed deposits and in upper water column than in lower water column in Jiaozhou Bay; (iii) in fair weathers, suspended sediment concentration (SPC) varied regularly within tidal cycles and neap-spring cycles, but the regularity was deformed in storms; and (iv) SPC was controlled by settling/resuspension near the bed and by advection at the surface at the study site with a depth of 20 m, suggesting weak vertical exchanges. It was concluded that SPM property of a low turbid bay is sensitive to pollution, and that the maintenance of low turbidity in the bay depends on less SPM supply, low waves and currents, and controlling on discharge of particulate pollutants.     

胶州湾浮游植物分子遗传多样性初步研究

用聚合酶链式反应扩增海洋浮游植物总体的核酮糖1，5-二磷酸羧化／氧化酶大亚基基因(rbcL)片段，建立该基因变异类型文库，并随机测定了38个rbcL大亚基基因片段序列，初步分析了海洋浮游植物分子遗传多样性。将≥97％的氨基酸序列相似性定义为种内变异，38个片段分别代表13个不同的物种，或称为不同的操作分类单元。与数据库序列比较发现，PPJZ01，PPJZll和PPJZ20可能是已报道的rbcL基因序列代表的物种，其它克隆在数据库中没有对应的近缘物种序列存在。系统学分析表明分离的克隆分别属于隐藻门、硅藻门、绿藻门和streptophyta等的浮游植物，极少数克隆来源于异鞭毛藻类、定鞭藻纲和原细菌。根据各操作分类单元克隆数计算得胶州湾浮游植物分子遗传多样性指数为1．97。研究结果为利用分子生物学方法剖分海洋浮游植物群落结构、研究海洋浮游植物动力学积累了基础数据。     

海岸带自然地理野外实习教学的设计及实现

青岛大学师范学院地理专业的自然地理综合野外实习教学长期将内陆山地和平原作为实习对象,忽视了海岸带自然地理实习.在胶州湾海岸带开展自然地理野外实习教学,强化有关海洋环境的地理教学内容,既适应了我国新一轮的高中地理教学改革对地理专业本科学生专业素质的要求,又克服了经费有限、时间短等不利因素对野外实习的限制.为培养学生的科研创新能力、研究性教学能力和实践教学能力,在实习总结阶段以学生进行小型课题研究取代了撰写野外调查报告或综合实习报告.
