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     

气溶胶中正构烷烃单体化合物稳定碳同位素分布特征初步研究

不同来源的气溶胶中正构烷烃稳定碳同位素的分布特征有比较明显的区别,以低陆生植物为主的高原清洁区,其气溶胶中正构烷烃δ＾１３Ｃ较轻,随碳数的增加,δ＾１３Ｃ较平平缓的曲线,以高等植物为主的海滨清洁区,正构烷烃δ＾１３Ｃ分布亦为较平缓的英线,但δ＾１３Ｃ较前者稍重,为－２８‰－－２７‰;人为污染严重的城市区,气溶胶正构烷烃δ＾１３Ｃ为－２９‰－－２５‰,且随碳数的增加有较大的变化。

岩溶关键带微量元素运移的时空变化:以豫西鸡冠洞为例

为探索岩溶关键带元素运移时空变化特征及过程,自2009年10月至2015年5月对我国北方典型岩溶关键带——河南西部鸡冠洞相互作用带中各组分(大气降水、土壤、基岩、洞穴滴水、洞穴现代沉积物)进行了连续定点监测及取样分析,共获得650个实验数据.对比了Ca、Mg、Ba、Sr、δ~(13)C及元素比值在不同组分中的变化情况及运移规律.结果表明:(1)土壤与基岩是滴水的主要物质来源,Mg、Ba、Sr符合"土壤-基岩"二元物源模型,但各自所占比例并不相同.(2)在空间上,洞穴系统相互作用带中各元素迁移相互联系.滴水继承了土壤及基岩的信号,现代沉积物又能延续滴水各元素的信息.元素在土壤纵剖面中表现出了明显的淋溶和淀积作用,最下层土壤较好地继承了基岩中微量元素的信息.(3)在时间上,洞穴系统相互作用带中各元素迁移复杂多变.土壤及滴水受降水淋滤作用影响皆表现明显的季节差异,然在岩溶水运移路径、PCP作用、极端干旱和年降水雨型的影响下,滴水元素浓度旱、雨季差异明显较土壤小.而PCP作用及元素选择性淋滤等因素又改变了沉积物中元素对滴水元素的延续特性.     

The impact of urban planning on land use and land cover in Pudong of Shanghai,China

Functional zones in cities constitute the most conspicuous components of newly developed urban areas,and have been a hot spot for domestic and foreign investors in China,which not only show the expanse of urban space accompanied by the shifts both in landscape(from rural to urban)and land use(from less extensive to extensive),but also display the transformation of regional ecological functions.By using the theories and methods of landscape ecology,the structure of landscapes and landscape ecological planning can be analyzed and evaluated for studying the urban functional zones‘layout.In 1990,the Central Govermment of China declared to develop and open up Pudong New Area so as to promote economic development in Shanghai.Benefited from the advantages of Shanghai‘s location and economy,the government of Pudong New Area has successively built up 7 different functional zones over the past decade according to their functions and strategic goals.Based on the multi-spectral satellite imageries taken in 1990,1997and 2000,a landscape ecolgy analysis was carried out for Pudong New Area of Sanghai ,supported by GIS technology.Green space(including croplands )and built-up areas are the major factors considered in developing urban landscape.This paper was mainly concerned with the different spatial patterns and dynamics of green space,built-up areas and new buildings in different functional zones,as influenced by different spatial patterns and dynamics of green space,built-up areas and new buildings in different functional zones,as influenced by different functional layouts and development strategies.The rapid urbanization in Pudong New Area resulted in a more homogeneous landscape.Agricultural landscape and suburban landscape were gradually replaced by urban landscape as the degree of urbanization increased.As a consequence of urbanization in Pudong,not only built-up patches,but also newly-built patches and green patches merged into one large patch,which should be attributed to the construction policy of extensive green space as the urban development process in Pudong New Area.The shape of green area of 7 functional zones became more and more regular because of the horticultural needs in Shanghai urban planning.Some suggestions were finally made for the study of future urban planning and layout.     

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。

An Assessment of Oil Pollution in the Coastal Zone of Patagonia,Argentina

The Patagonian coast is considered a relatively pristine environment. However, studies conducted along coastal Patagonia have showed hydrocarbon pollution mostly concentrated at ports that have fishing, oil loading, general merchant, and/or tourist activities. A high value of total aliphatic hydrocarbons (TAH) was found at the Rawson fishing port (741 μg/g dw). In other ports with and without petroleum-related activities, hydrocarbon values were approximately 100 μg/g dw. The highest values for TAH and total aromatic hydrocarbons (TArH) were found in Faro Aristizábal, north of San Jorge gulf (1304 and 737 μg/g dw, respectively). This is very likely the result of petroleum-related activities at the Comodoro Rivadavia, Caleta Cordova, and Caleta Olivia ports located within this gulf. In other coastal areas away from potential anthropogenic sources, hydrocarbon values were less than 2 and 3 μg/g dw for TAH and TArH, respectively. This review of published and unpublished information suggests that ports are important oil pollution sources in the Patagonian coast. More detailed studies are needed to evaluate the area affected by port activities, to understand the mechanisms of hydrocarbon distribution in surrounding environments, and to assess bioaccumulation in marine organisms. Despite that some regulations exist to control oil pollution derived from port and docked vessel activities, new and stricter management guidelines should be implemented.
