2001-2010年中国区域旅游效率评估

选择旅游酒店数、旅行社数、旅游酒店从业人员数和旅行社从业人员数为旅游投入因素,旅游总收入为产出变量,运用数据包络分析方法中的 C2 R 模型分析2001-2010年中国区域旅游效率及其空间格局和变化趋势。中国四大区域的平均旅游效率由高至低依次为东部地区、东北地区、中部地区和西部地区。在31个中国大陆省级行政区中,天津在2001-2010年期间每年都为旅游效率最高的省份。从时间的角度,中国区域旅游效率经历了一个波浪式变化过程,2003年和2008年是2个明显的波谷。2001-2005年四大区域旅游效率的变化过程基本一致。2005-2010年四大区域旅游效率变化各不相同,东部地区呈逐步下降趋势,中部地区先增长、2010年开始下降,西部地区为起伏不定,东北地区为持续增长。     

国外非物质文化遗产旅游研究综述与启示——基于近20年ATR、TM文献的考察

本文通过对近二十年来国际著名旅游学术期刊《Annals of Tourism Research》、《Tourism Management》所刊载的有关非物质文化遗产旅游文献的学术梳理发现,国外研究主题主要集中在非物质文化遗产旅游的真实性与商品化、政治性质、旅游影响、立法保护、动力机制等方面。研究方法多采用民族志田野调查法、参与观察法、问卷调查法、深度访谈法等,理论探索多基于文化人类学和社会学等相关理论。其学术取向明显不同于国内非物质文化遗产保护与旅游开发的应用对策研究视角,具有一定的启发意义。     

乡村旅游社区景观空间演化研究

乡村旅游社区景观空间是在乡村旅游社区地域范围内,由于人类活动所产生的文化景观的总和。近年来,随着乡村旅游的快速发展,乡村旅游社区景观空间的演化受到人们的高度关注。本文将乡村旅游社区景观空间的演化置于演化经济地理研究框架内,认为其经历形成之前阶段、形成阶段、发展阶段和锁定或创新阶段四个阶段,每个阶段特征和演化机制各不相同。乡村旅游社区景观空间的演化是在遗传机制、变异机制等内因和选择机制、起点状态、关键事件等外因共同作用下,随着产业变迁而发生的具有路径依赖特征的演化过程。     

基于双视角竞争态与亲景度中国入境旅游客源市场分析

利用市场竞争态与亲景度构建综合评价模型,分析1998~2000年和2009~2011年两个时段中国入境旅游客源市场及其变化。结果发现：（1）1998~2000年美国等为明星市场,日本为金牛市场,印度等为幼童市场,英国等为瘦狗市场。（2）2009~2011年新加坡等为明星市场,韩国等为金牛市场,印度等为幼童市场,瑞典等为瘦狗市场。（3）受空间距离的影响,强亲景市场比较稳定,弱亲景、弱疏景、强疏景3种市场则有可能发生较大变化。（4）经过10年的发展明星市场和幼童市场数量保持不变,金牛市场增加到3个,瘦狗市场减少到3个,客源市场逐步壮大,入境旅游市场发展良好。     

A georeferenced agent-based model to analyze the climate change impacts on ski tourism at a regional scale

One main argument for modeling socio-ecological systems is to advance the understanding of dynamic correlations between various human and environmental factors, including impacts and responses to environmental change. We explore the shift in skier distribution among ski resorts taking into account the behavioral adaptation of individuals due to the impact of climate change on snow conditions. This analysis is performed at a regional scale by means of a coupled gravity and georeferenced agent-based model. Four different scenarios are considered. Two scenarios assume an increase of winter mean temperature of +2°C and +4°C, respectively, taking into account only natural snow conditions. Two additional scenarios add the effect of snowmaking to enhance the natural snow depth and extend the skiing season in the +2°C and +4°C base scenarios. Results show differing vulnerability levels, allowing the classification of ski resorts into three distinct groups: (1) highly vulnerable ski resorts with a strong reduction in visitors attendance for all climate change scenarios, characterized by unfavorable geographical and attractiveness conditions, making it difficult to ensure snow availability in the future; (2) low vulnerability ski resorts, with moderate reduction in season length during a high climate change scenario but no reduction (or even an increase) in a low one, characterized by ski resorts with a medium capacity and attractiveness to ensure enough snow conditions and capture skiers from other ski resorts; and (3) resilient ski resorts, with good conditions to ensure future snow-reliable seasons and outstanding attractiveness, allowing them to offer longer ski seasons than their competitors and potentially attracting skiers from other closed or marginal resorts. Ski resorts included in this last group increase their skier attendance in all climate change scenarios. Although similar studies in the literature foretell a significant reduction of the ski market in the near future, another probable effect outlined in this study is a redefinition of this market due to a redistribution of skiers, from vulnerable ski resorts to more resilient ones.     

休闲旅游——国内外研究现状、差异与内涵解析

休闲旅游是当前我国旅游业发展的热点,政府和业界都对休闲旅游的发展高度重视,国内学术界也对这一问题进行了大量研究,但迄今为止有关休闲旅游的内涵仍缺乏统一的认识,这不利于人们对休闲旅游做进一步的深入研究。该文基于对国内外研究现状的分析,阐释了休闲旅游与休闲、旅游、观光旅游和度假旅游等概念之间的关系,并结合我国旅游发展的情境和特点,尝试性地对休闲旅游的内涵进行了解析,以期能够为休闲旅游未来的研究和实践发展提供一定的理论指导。     

New progress and problems of Quaternary moraine dating in the Tibetan Plateau

Since the 20th century, numerous Quaternary moraine dating methods have emerged, including lichenometric, moraine 14C, quartz sand thermoluminescence （TL）, electron spin resonance （ESR）, optically stimulated luminescence （OSL） and 10Be, 26A1, 36C1, 3H, 21Ne nuclide dating methods. These dating methods are widely applied to determine moraine ages and have provided a large dataset. Unfortunately each method has its defects. In this paper, we will review these various dating methods and provide some comments.     

Eualus heterodactylus sp. nov., a new hippolytid shrimp from Chinese coast of the Yellow Sea （Crustacea,Decapoda, Caridea）

A new species from the caridean family Hippolytidae, Eualus heterodactylus sp. nov. is described and illustrated based on the specimens collected from Chinese coast of the Yellow Sea. The new species is a part of an informal species group characterized by the possession of epipods on the anterior three pairs of pereopods, and is distinguished from other species of this group by the dactyli of the third to fifth pereopods possessing distinctly stair-like flexor margins in males.

坛紫菜耐低盐品系的选育与特性分析

本实验室采用人工诱变技术获得一个坛紫菜耐低盐品系(YZ-7),为了验证该品系的耐低盐性状能否遗传,本文对其壳孢子和F1叶状体的低盐耐受性分别进行了测试,并以坛紫菜野生品系(WT)作为对照,结果表明:在不同盐度下培养2周的YZ-7和WT的壳孢子,在26盐度组存活率无显著差异;在15盐度组,YZ-7的壳孢子存活率和假根发生率分别比WT提高了34%和35%;在8和5盐度组,YZ-7的壳孢子存活率、分裂率及假根发生率分别比WT提高了65%、32%和62%,以及137%、80%和154%;在3盐度组,YZ-7的壳孢子存活率和分裂率分别比WT提高了458%和171%,其中约44.9%的YZ-7壳孢子萌发体能形成假根,而WT的壳孢子萌发体基本上不长假根。在26盐度中培养35d后的F1叶状体再分别在26、15、8、5和3盐度下培养30d,YZ-7叶状体的特定生长率分别为WT的1.7、1.9、1.5、1.6和1.6倍,绝对生长率分别是WT的3.4、4.1、1.8、2.0和1.6倍。此外,YZ-7叶状体的叶绿素荧光活性(PSⅡ最大光量子产量、实际光量子产量)及三种主要光合色素(叶绿素a、藻红蛋白和藻蓝蛋白)的含量也明显高于WT。上述结果证实,坛紫菜选育品系YZ-7是一个耐低盐且生长快的优良品系,其优良性状可稳定传递给下一代,有望被培育成适宜栽培的新品种。
