广东汕头海岸湿地鸟类群落与多样性的研究

对广东汕头海岸湿地的鸟类资源进行了调查，共记录鸟类100种，隶属15日31科，其中古北界鸟类43种，东洋界鸟类45种，广布种鸟类12种。区系组成呈南北鸟类混杂分布，鸟类的多样性表现出明显季节性。该湿地有国家二级重点保护鸟类10种，中日候鸟保护协定名录中的鸟类43种。5个湿地样区主要鸟类种类和数量的调查结果表明，汕头海岸湿地是水鸟类重要的越冬栖息场，鸟类群落多样性指数以三屿围和六合围两个样区较高，分别为3．2306和3．2283；濠江口的多样性指数较低，为1．98l。群落多样性指数的高低主要受物种数量和各物种数量均匀度的影响。文章还提出了对鸟类资源保护和管理的建议。     

EU-wide survey of polar organic persistent pollutants in European river waters

This study provides the first EU-wide reconnaissance of the occurrence of polar organic persistent pollutants in European river waters. More than 100 individual water samples from over 100 European rivers from 27 European Countries were analysed for 35 selected compounds, comprising pharmaceuticals, pesticides, PFOS, PFOA, benzotriazoles, hormones, and endocrine disrupters. Around 40 laboratories participated in this sampling exercise. The most frequently and at the highest concentration levels detected compounds were benzotriazole, caffeine, carbamazepine, tolyltriazole, and nonylphenoxy acetic acid (NPE₁C). Only about 10% of the river water samples analysed could be classified as “very clean” in terms of chemical pollution. The rivers responsible for the major aqueous emissions of PFOS and PFOA from the European Continent could be identified. For the target compounds chosen, we are proposing “indicative warning levels” in surface waters, which are (for most compounds) close to the 90th percentile of all water samples analysed.     

海岸带综合管理的区域性特征及其发展机制

在综述国内外海岸带综合管理（ＩＣＺＭ）进展的基础上，以人地关系地域系统为理论基础，论述了ＩＣＺＭ的区域性特征。从地理学看，海岩带是一个开放的复杂的巨系统，有着明确的边界范围，具有可度量性。从管理学看，其模式的多样性反映了区域自然条件和社会条件的差异性，是人地关系双向运动平衡协调的结果，从社会学看，其战略实施先在地方级别上应用，在获得足够的经验或成熟之后，再推广到地区级、省级和国家级的计划中去的空间     

深圳湾及邻近水域总溶解磷的来源和时空分布

依据2000~2012年每月一次的调查资料,简要描述和讨论了深圳湾及邻近沿岸水域中总溶解磷(TDP)质量浓度的时空分布,并结合现场盐度和溶解无机磷(DIP)实测数据探讨TDP的组成和来源以及DIP和溶解有机磷(DOP)之间的转化.结果表明,深圳湾和珠江口东南部沿岸TDP质量浓度分别为(0.26±0.22)和(0.05±0.02)mg/L.研究期间,珠江口东南部沿岸TDP质量浓度的年内和年际变化不大,趋势平稳.在深圳湾,由于受到周边陆源排放的影响,TDP质量浓度在丰水期较低,枯水期较高,且在2000~2004年呈上升趋势,从0.24mg/L上升至0.33mg/L, 而在2005~2012年则呈下降趋势,从0.33mg/L下降至0.16mg/L.研究海区中的TDP具有“保守性”,主要来自陆源排放.依二元混合质量平衡模式估算的珠江口东南部沿岸TDP的陆源质量分数约为53.9%,而深圳湾的均大于80%. TDP的赋存形态从河口的以DIP为主逐渐转变至近外海的以DOP为主,可能暗示磷从河口向海迁移期间,复杂的生物地球化学过程使DIP转化为DOP的速率大于DOP转化为DIP的速率.     

温州沿海大型塑料垃圾排放特征研究

通过调查温州滨海地区近岸海上渔业、航运码头、滨海旅游及餐饮业等行业塑料垃圾的排放,分析行业区域塑料垃圾赋存特征,并初步估算各行业塑料垃圾排放量.结果表明：海上渔业活动区中,以避风塘渔港（S4）塑料垃圾占比最高（91.68%）,且以聚乙烯、聚苯乙烯和聚丙烯塑料为主,而东沙渔港（S2）和霞关海水养殖区（S6）以聚苯乙烯泡沫为主,占比分别为26.75%和23.66%.海滩餐饮活动区的塑料垃圾最少,塑料垃圾占比为33.13%.各活动区塑料垃圾的主要类型有塑料袋、塑料瓶、塑料盒、塑料管及破碎的塑料块.据估算,海上渔业活动区与滨海旅游区年排放塑料垃圾量约为1.21×10⁴t/a.为从根本上防治海洋塑料垃圾和海洋微塑料污染,需首先对沿海各行业的塑料垃圾排放源头加强管理,如海水养殖与海洋捕捞活动.     

广东-海南海岸带生态系统服务价值评估

采用Costanza等的分类系统和相关服务的单位价值，根据广东省1987年海岸带和海涂资源综合调查报告和其他相关资料，初步估算出广东—海南海岸带的生态系统服务的总价值为316．97亿美元／a，其中陆地为187．38亿美元／a、海域为129.59亿美元／a。该总价值占全国总价值的407％，养分循环、水分调节、休闲和水分供给等服务的价值突出，分别为全国总价值的6．17、3.98、3．66和3.37％由于自然生态系统的复杂性和不确定性，以及计算参数和方法存在缺陷，因而得到的只是一个偏低的保守值，有待今后改进。     

Designing principles of an ecological water storage basin on coastal saline: a case study

The degradation of water source environment becomes serious problems accompanying with rapid urbanization in China.Ecological engineering provides ecologically sound and cost-effective solution to solving this problem. As a case study, a 15 hm^2 ecological water storage basin for a water plant was designed and constructed on the TEDA area in Tianjin City. Located on saline, the construction of this project has to face serious difficulties, such as high salinity, scarce seed banks of macrophytes, and strong winds. Freshwater replacement, soil amendation and macrophytes planting at the basinshore, wooden water breaker and plastic membrane installation and other measures were conducted for the assistance of plant community establishment. The result showed that the chloride concentration in the basin water decreased from 11600 mg/L to less than 100 mg/L, and the chloride content in the basin sediment decreased from 2.1% to 0. 35 % after freshwater soaking. The introduced macrophytes of 8 species all survived and 11 other macrophytes species were occurred in the basin. A new ecosystem was created with increased biological diversity in the original saline, and the water quality was improved. This ecological water storage basin also provided a pleasing landscape for local people.

浙江北部海域的具齿原甲藻赤潮分析

对2003年5月浙江北部沿海海域的一次具齿原甲藻赤潮进行了调查分析,结果表明:细胞数106/L是具齿原甲藻发生赤潮的临界值,赤潮生物数量与DO、COD、叶绿素a、被囊类及水母有较好的正相关作用,与桡足类、箭虫类则呈相反的走势,具齿原甲藻赤潮的暴发及持续并不需要过高的营养条件,其连续、大规模的发生估计与海洋渔业资源及生态系统的变迁有着密切的联系。
