Studying the loyalty of eco-tourists from the perspective of tourist experience is important to the continued development of mountain ski tourism. Based on the flow experience theory, we developed and tested a structural equation model to examine relationships among flow experience, positive emotions and the loyalty of eco-tourists. Survey data from 324 eco-tourists with skiing experience at Daweishan Mountain Ski Resort was used for exploratory factor, confirmatory factor and path analyses. Results revealed five dimensions of flow experiences of eco-tourists： Concentration on task at hand, Loss of self-consciousness, Transformation of time, Autotelic experience, and Challenge-skill balance. As hypothesized, influences of Transformation of time, Autotelic experience and Challenge-skill balance on positive emotions were significant and positive. Concentration on task at hand, Autotelic experience, Challenge-skill balance and positive emotions positively influenced the loyalty of eco-tourists. Suggestions for developing ecotourism products are discussed such as designing a conductive environment to activate flow experience, providing personalized service to promote positive emotion, and developing experiential tourism activities.展开更多

Miao)群落是中国南方和越南北方喀斯特季节性雨林最为典型的特有群落之一,对维护区域生态系统稳定具有重要作用。原生性较强的蚬木群落因人为活动而所剩无几,其物种组成和群落结构研究目前还鲜见报道。本研究通过典型样方法对分布在云南大围山国家级自然保护区的蚬木群落进行了调查和分析。结果显示:(1)4 800 m^(2)样地内共记录维管植物45科78属92种,种子植物区系以热带分布为主(分别占科、属、种总数的73.68%、94.20%和99.05%),生活型以高位芽植物为主(占总种数的79.12%),Shannon-Wiener指数为2.84,Simpson指数为0.14,Pielou指数为0.63。(2)群落共分3层,乔木层18科32属38种1 593株,灌木层18科27属29种453株(丛),草本层10科19属22种357株(丛),层间植物17科20属23种232株。(3)乔木层3个亚层的重要值比较分析结果显示,锦葵科的蚬木为群落的建群种,大戟科的肥牛树(Cephalomappa sinensis(Chun&F. C. How)Kosterm.)为特征种,故将该群落命名为蚬木+肥牛树群落(Excentrodendron tonkinense+Cephalomappa sinensis community)。(4)乔木层优势种年龄结构以“L”型为主。研究结果表明该群落为物种丰富、组成稳定、结构明显、更新良好的喀斯特季节性雨林原生群落。展开更多
脂肪酸是影响家鸡肉品质的重要风味物质,Δ6-脂肪酸脱氢酶基因(FADS2)是不饱和脂肪酸生物合成过程中的关键酶。研究以武定鸡和大围山微型鸡为研究对象,检测肌肉组织中脂肪酸含量及FADS2基因表达量,比较不同鸡种脂肪酸含量及FADS2基因表...脂肪酸是影响家鸡肉品质的重要风味物质,Δ6-脂肪酸脱氢酶基因(FADS2)是不饱和脂肪酸生物合成过程中的关键酶。研究以武定鸡和大围山微型鸡为研究对象,检测肌肉组织中脂肪酸含量及FADS2基因表达量,比较不同鸡种脂肪酸含量及FADS2基因表达差异。结果显示,整体上,武定鸡腿肌中饱和脂肪酸(SFA)、单不饱和脂肪酸(MUFA)、不饱和脂肪酸(USFA)、多不饱和脂肪酸(PUFA)、必需脂肪酸(EFA)及总脂肪酸含量和FADS2 m RNA表达量均显著高于大围山微型鸡,且在部位和周龄上存在显著差异。研究表明,武定鸡风味比大围山微型鸡优良,FADS2基因是影响家鸡肉品质的重要候选基因。展开更多
