基于DPSIR模型的生态港口指标体系研究

生态港口指标体系的建立是生态港口从理论研究阶段进入可操作的实际应用阶段的重要步骤,建立生态港口指标体系的实质就是确定生态港口的具体建设内容和考核标准体系.在生态港口内涵的分析基础上,提出了建立生态港口指标体系的基本框架、原则和方法,并根据"驱动力-压力-状态-影响-响应"模型框架,以天津生态港口建设为背景,建立了天津生态港口建设与评价指标体系.

湛江市典型区域蔬菜硝酸盐和亚硝酸盐污染评价

在湛江市典型区域采集了14个蔬菜品种的28个样品,分析了样品中硝酸盐和亚硝酸盐的含量,对其污染状况及食用安全性进行了评价.结果表明:叶菜类硝酸盐含量普遍较高,有8个样品超标,根茎类和瓜果类硝酸盐含量均没有超标,而所有样品亚硝酸盐含量均较低.根据WHO/FAO规定的硝酸盐日允许摄入量换算得到的标准进行评价,青瓜、莲藕、葫芦瓜、花菜、包菜等品种食用较为安全,而萝卜、瓢瓜和生菜、大白菜等蔬菜经盐溃或煮熟后也可放心食用;但菜心、芥菜、通心菜、小白菜和油麦菜等蔬菜属于严重污染,食用可能会对人体健康带来风险.

Human and organizational factors in Chinese hazardous chemical accidents: a case study of the ‘8.12’ Tianjin Port fire and explosion using the HFACS-HC

Human and organizational factors have been proven to be the prime causes of Chinese hazardous chemical accidents (HCAs). A modified version of the Human Factors Analysis and Classification System (HFACS), namely the HFACS-Hazardous Chemicals (HC), was developed to identify the human factors involved in Chinese HCAs. The ‘8.12’ Tianjin Port fire and explosion, the costliest HCA in recent years, was reanalyzed using this framework, and the results were compared with the official accident inquiry report to determine their differences related to the identification of human and organizational factors. The study revealed that interacting human factors from different levels in Ruihai Company led to this catastrophe, and the inquiry report had limitations in the identification of human factors and the guidance for similar accident prevention. This study showed the applicability of the HFACS-HC in HCA analyses as well as the necessity to recommend this approach for future HCA investigations.     

Use of Faunal Indicators for Assessing the Impact of a Port Enlargement near Bilbao (Spain)

In order to assess the effects of the execution of the Port of Bilbao Enlargement Project, epifauna living on hard substrata and environmental parameters were quantitatively investigated from 1994 to 1996. A programme of repeated non-destructive sampling at 8 stations was carried out during the construction period of a breakwater and the filling operations on the shoreline. A correlation analysis was used as a method to extract potential indicator species of particular environmental conditions measured in the field. We postulate that the remaining species (about 80% of the total species data set), insensitive to any of the investigated environmental factors, were unnecessary for the purposes of assessing the environmental impact caused by the port building works. Classification and ordination techniques were then conducted at two contrasting levels by using the full species data set and the selected faunal indicator data subset. All plots showed separation of sampling sites in 3 major groups, which were easily related to the perturbations caused by a siltation gradient from the estuary mouth. This suggests that the amount of effort required in the enumeration of all the organisms sampled may be dramatically reduced by identifying only faunal indicators of environmental discontinuities in the field. So far, the engineering works developed on the western side of the bay have not caused dramatic temporal changes in species composition, or at least they have not had an effect that was larger than the variations detected among the study sites due to siltation from the estuary mouth.

Survey on environmental monitoring requirements of European ports

A group of 26 European ports was interviewed to understand their requirements for environmental information and to establish how widespread the use of Earth Observation (EO) data was amongst them. Aspects covered by the research included port profile characterisation, environmental management activities, environmental needs and current monitoring practices. The study reflected the diversity amongst European ports and their environmental performances. Most of the ports were publicly owned and located in estuaries and rivers. General cargo was the most popular commodity handled. Practically all the ports had an environmental policy in place and half of them had been accredited by an external body. The main environmental parameters that ports required to be monitored were marine related issues (currents, waves and tide), water quality, meteorological parameters, turbidity and sediment processes. The principal driver for monitoring was maintaining key port operations, followed by legislation, and local responsibilities. Ports in general collected their own data in situ and only one-third had used remotely sensed data (data from Earth Observation satellites or from airplane mounted sensors) for environmental purposes. Half of them used computer modelling. This study was conducted within the framework of the European funded port environmental information collector project (PEARL).     

湛江市农村居民点用地面积变化及驱动力分析

利用湛江市1996—2005年农村居民点用地面积数据及相关社会经济数据,在分析农村居民点用地面积变化的基础上,采用主成分分析法对其进行了驱动力分析。结果表明,近十年来湛江市农村居民点用地总面积呈逐年上升的趋势,而农村居民点人均用地面积总体呈减少趋势。湛江市农村居民点用地面积增加主要集中在徐闻、吴川和市区。湛江市农村居民点用地面积变化主要受农村人口增长、农村经济发展、农业结构调整、农村交通发展和乡镇企业发展等因素的影响。
