Effect of seaweed proliferation on benthic habitat quality assessed by Sediment Profile Imaging

Changes in sediment quality, with special reference to benthic habitat conditions resulting from macroalgae overgrowth, were studied in the Venice Lagoon, Italy. Data were collected biweekly in spring and summer from 1993 to 1998 and from 2001 to 2002, as part of the macroalgae growth control strategies managed by the Venice Water Authority-Consorzio Venezia Nuova. Benthic habitat conditions were studied by means of Sediment Profile Imaging, which allowed the collection of several variables: aRPD (apparent redox potential discontinuity), prism penetration depth, presence of anoxia on the surface of the sediment, presence of reduced gas bubbles, stage of benthic colonization. All these variables led to the calculation of an environmental index (Organism–Sediment Index, OSI), which was then related to physical variables and macroalgae abundance. Until 1996, the overall benthic habitat of the Venice Lagoon showed almost stressed conditions; from 1997, the seaweed biomass rapidly declined and the OSI increased significantly. The OSI seemed to be affected by seaweed biomass, sediment compactness and water depth. Macroalgae biomass greater than 4.5 kg/m² led to the complete disappearance of stage III of benthic colonization; values as low as 0.70 kg m² already had a severe impact on recolonization. SPI attributes indicated the main mechanisms that could have contributed to the benthic quality: seaweed proliferation is often followed by rapid decay of macroalgae biomass, especially when present in large amounts. The decrease in seaweed biomass often results in oxygen depletion in the water column and thus in the sediment, preventing complete benthic colonization. This research confirms the importance of in situ rapid reconnaissance surveys to assess the impact of eutrophication on the benthic habitat.     

西安地铁2号线行政中心站空间设计探究

随着国内地铁建设的快速发展,地铁站的空间设计显得越来越重要。以西安地铁2号线行政中心站的空间设计为例,通过对行政中心站所处的城市环境、功能分区以及空间构成特点的分析和研究,提出地铁空间的合理设计,需要在充分满足功能的基础上,有效利用公共空间的界面、导向、灯光等元素来展示地域文化特色。这样不仅能提升地铁站的空间品质、突出空间的可读性,更能带给乘客丰富的乘车体验和地域感受。对国内地铁的建设有着积极的借鉴意义。

Coastal Tourist Interest in Value-Added,Aquaculture-Based,Culinary Tourism Opportunities

Despite increasing focus on sustainable aquaculture investment in the U.S. coastal zones, the aquaculture industry continues to face skepticism among consumers due to perceived negative environmental impacts, and health and food safety concerns. Partnering with culinary tourism and local food promotion efforts has potential for improving public outreach about the benefits of aquaculture, especially in coastal destinations where sustainable marine aquaculture and tourism are both occurring. Culinary tourism implies that local foods reflect the local livelihood and culture, and may be important to the tourist's experience. Aquaculture is becoming increasingly valuable to coastal destinations for assuring the steady availability of local seafood to meet demand and retaining commercial fisheries as a means to differentiate themselves to tourists. This study examined the role of subjective knowledge and attitude about aquaculture, and their effect on intention to participate in value-added culinary aquaculture tourism experiences. The study found that tourists' subjective knowledge and attitude about aquaculture influenced intentions to participate in culinary aquaculture tourism. In order for farmers or tour operators to be successful in diversifying with value-added culinary aquaculture, attention needs to be paid to educating consumers, which may be possible through strategic partnerships with tourism organizations, chefs, and restaurants.     

构建快速公交系统无缝衔接旅游区域与城际轨道站的分析与探索

本文分析了大中城市中短途休闲旅游的交通出行特征,探讨了当前中短途休闲旅游交通出行方式中存在的公共交通分担率较低等问题,论述了当前交通需求下积极构建快速公交系统无缝衔接休闲旅游景区与城际轨道站点的必要性。结合交通运输部提出的"快进"的旅游交通运输系统指示,通过构建无缝衔接换乘体系,打造能够适应当前休闲旅游"舒适、安全、便捷、快速"交通出行需求的快速公交无缝衔接体系,具有重要意义。     

北京市旅游交通方式选择行为研究

为防止北京市旅游高峰期间景区周边交通混乱以及城市交通路网负荷增加,选取北京市三 处景点进行问卷调查,将游客的年龄、是否有车、月收入、同行人数及同伴类型等数据作为影响游客交通方式选择的因素。与此同时,对所需数据进行有效性检验,进而分析不同游客的出行方 式特性,利用非集计模型对游客的交通方式选择行为进行研究。结果显示：游客的年龄、是否有车、月收入、同行人数以及同伴类型这几类因素对游客的交通方式选择的影响均显著,并得到游 客对私家车、出租车、地铁及公交车这四类交通方式选择的比例,分别为17%, 7%, 54%, 22%。研究表明,北京市旅游交通方式的需求以公共交通为主,尤其是对轨道交通的需求,为此建议进 一步加大北京市旅游公共交通系统建设,提高旅游交通的服务质量。

A Training Framework for Understanding Conflict in the Coastal Zone

The coastal zone is attractive for human settlement because it tends to be resource rich, providing a good location to generate incomes and livelihoods. Equally, however, it is a complex and powerful natural environment, which means that the coastal zone often becomes a focus of conflict with multiple users competing for limited space and resources. Understanding the causes of, and determining solutions to, the ensuing problems requires inputs from a range of analyses across sectors and disciplines. However, different disciplinary and sectoral approaches frequently use different investigative methods, language, and means of presenting results. This article presents a framework that has been developed in collaboration with Indian institutions over the past three years in an effort to address some of these fundamental problems of analysis and translation into policy action. Key components addressed by the framework are strengthening the capacity to practice, knowing how to proceed and how to find out what needs to be known using experience-based problem solving.
