世界旅游精品建设目标下的张家界旅游环境管理对策研究

建设世界旅游精品是张家界制定的旅游业发展的战略目标，一流的旅游环境条件是实现这一目标的必备条件。然而，张家界目前的旅游环境与世界旅游精品存在差距，环境管理中存在基础性工作、基础性研究比较薄弱、制度不够健全等方面的问题，影响了环境管理效率。在分析研究张家界环境管理中存在问题的基础上，针对性地提出保护、改善环境的对策，是实现世界旅游精品战略目标的基础工作。

Endpoint ‘floating leaves’ of <Emphasis Type="Italic">Potamogeton natans</Emphasis>: A new method to evaluate the development of macrophytes in pond mesocosms

Goal, Scope and Background One of the advantages of long-term mesocosm experiments as compared to short-term standard toxicity tests in the laboratory is the potential for detecting secondary effects due to the interaction of species and recovery with biomass of macrophytes being an important endpoint. However, generating biomass data by harvesting is often laborious, time-consuming, costly and restricted to the end of the experiment. Moreover, valuable information may get lost, in particular in single application studies, since maximal primary effects and secondary effects or recovery occur per se at different times. Potamogeton natans was used as an example in order to test whether number and area of floating leaves can be reliably measured and be used as intermediate and final endpoints in mesocosm effect studies. Methods Digital photos, which were taken of the water surface in the course of an indoor pond mesocosm study on herbicide effects, were subjected to image analysis. The results were compared to wet weight and ash-free dry weight of Potamogeton at the end of the herbicide study. Results and Discussion Both number and area of floating leaves indicated the same herbicide effects as wet weight and ash-free dry weight of Potamogeton. Error introduced by the different work steps is small and can be further minimised by a number of method improvements. Recommendations and Perspectives In indoor mesocosm studies, errors due to the perspective adjustment may be circumvented by taking the photos perpendicular to the water surface. Correction for lens aberration, identical light conditions and the use of fluorescence images are considered promising. Field applications are proposed.     

大型会展对举办地旅游形象的提升路径及效应分析——以上海世博会为例

大型会展对提升举办地旅游形象效应成为旅游学界当前关注的热点。以上海世博会为例，采用案例分析法和文献研究法，在分析过程中结合定量分析和定性分析，研究大型会展对旅游地的形象效应。研究表明，上海世博会主要通过聚焦作用下的旅游形象建设、光晕遮蔽作用下的网络宣传、世博宣传片与上海旅游形象联手营销、旅游企业的积极行为以及政府的支持与配合等5种途径提升上海都市商务会展、都市文化、都市休闲等旅游形象，提出利用大型会展的聚焦作用和光晕遮蔽作用提高举办地知名度，将大型会展宣传与举办地旅游形象宣传相结合，将大型会展建设融人到城市的旅游形象建设之中等3个方面提高旅游地形象。

基于城市体系的中部6省区域旅游合作研究

城市是区域经济发展的依托,区域旅游合作水平的高低同样与区域城市体系的发育程度紧密相关。以中部6省城市体系为构架,对中部6省省际间区域旅游合作进行了探讨,并从节点优化、线路组织、市场拓展等方面提出了6省间区域旅游合作的构想,以期为中部六省区域旅游合作程度的进一步加深提供一定的借鉴。     

面向灾害应用的遥感影像融合统一理论体系设计

由于缺乏统一的理论体系指导,目前遥感影像融合研究相对比较混乱。针对像素级融合统一理论框架的思想,指出了遥感影像融合研究的方向和思路,将像素级融合统一理论框架逐步向特征级和决策级推广,着重发展了一套遥感影像融合统一理论体系。在统一体系下,面向灾害监测应用,按照理论研究、方法研究和应用研究的3个层次进行该理论体系的设计。     

Building resilience to climate change – the role of cooperation in alpine tourism networks

While there is ample – though partially contradictory – evidence regarding the effects climate change will have on various regions of the world, there is only very limited work dedicated to the analysis of different governance structures, and how these structures are likely to influence the resilience of alpine tourism systems in the face of climate change. We present an analytical framework based on network theory, and apply this to the Swiss case study destination of Engelberg, in order to deduct a number of insights for the future assessment of resilience based on the cooperation of local actors. The main aim of the paper is to come up with comparable resilience metrics based on social network analysis in order to assess the structural strengths and weaknesses of a geographically delimited tourism system in the face of climate change. Together with the action potential of the individual actors these structural properties influence the adaptive capacity of both individual actors, and the tourism system as a whole. In line with comparable studies, we identify structural strengths and weaknesses around the core-periphery distribution (centrality), subgroups (modularity) and information flows (path length). We find that the Engelberg network follows an almost ideal-typical scale-free structure and the overall cooperation rate (density) is comparable to other tourism networks. The main weaknesses of the network with regard to climate change resilience are the lacking integration of public sector actors and the relatively high number of actors in the periphery of the network.     

大渡河上游丹巴地区地质灾害的地貌分维特征解析

地貌对地质灾害的分布、类型、规模与危害等特征具有重要的影响,宏观及微观地貌指标均能在一定程度上刻画其作用特征。应用高分辨率遥感影像详细解译崩塌和滑坡灾害,采用高精度DEM和滑动窗口技术提取地貌分维特征,并用其解析灾害分布的地貌特征。结果表明:灾害体的内部与后壁、前缘、侧壁和邻区均表现出较为明显的分异性,崩塌的微地貌分异特征较之滑坡显著,大型、厚层、老(古)崩塌及滑坡分异特征更为突出。计算地貌分维值可有效识别与其同时期的或更早的地质灾害,也可间接挖掘新发生灾害的微地貌复杂性和离散性。     

中国市域旅游流网络结构空间分异及其效应研究——基于携程旅行网的大数据挖掘

大数据驱动的旅游流网络结构研究是旅游流深化研究的主要方向之一。利用网络爬虫技术抓取携程旅行网上中国市域尺度的旅游线路及相关数据,在构建O-D矩阵的基础上,揭示网络结构指标的空间分异及其效应。中国市域旅游流网络具有以下特征：网络同质性较小;不同主题类旅游流流量总体上遵从东多西少、东南多西北少的总体格局;中国市域旅游流网络形成了五大高值集聚区,分别为长三角城市群、泛珠三角地区、云南内部、青海—甘肃交界地区、北疆地区;中国市域旅游流网络还具有显著的资源—经济指向性,“结构”效应总体不显著。未来需要进一步重视区域旅游网络化的发展特征,在尊重空间规律的基础上,发挥核心组团的辐射作用,发挥“资源—经济”的双核驱动,促进跨区域旅游合作。
