Tradeoffs Among Resource,Social, and Managerial Conditions on Mountain Summits of the Northern Forest

This research examined the relative importance of indicators and standards of quality at three mountain summits in the Northern Forest. The three summits ranged from low to high levels of use, development, and management. Computer-generated photographs were used to present a range of resource, social, and managerial conditions in a stated choice survey. Results suggest that visitors prefer minimal resource impact, few other people, and low intensity management. However, when faced with tradeoffs, respondents accept more intensive management to help ensure resource protection. Findings also suggest that a range of recreation opportunities should be provided at mountain summits in the Northern Forest.     

Exploring Relationships Between Recreation Specialization,Restorative Environments and Mountain Hikers’ Flow Experience

This study explored the relationships between the perception of restorative natural environments, specialization in mountain hiking and flow experience. On-site interviews were conducted at mountain huts in the Salzkammergut, Austria, in 2009. The analysis of 369 hikers suggests that a relationship exists among recreation specialization, the perception of restorative environments and flow. With increasing specialization, people are more likely to experience flow. The restorative quality dimensions of “being away,” “fascination” and “compatibility” with the mountainous landscape were positive predictors of flow experience.     

Dynamics of Progression in Mountain Bike Racing

A major tenet of the recreation specialization framework is that people progress to higher stages of involvement over time. Results from recent studies suggest that involvement may actually be marked by stability or decline. Little is known about the extent to which people progress in outdoor activities where objective standards of performance exist. The purpose of this study was to examine the antecedents of objective and subjective progression among competitive mountain bike racers. Specialization dimensions of behavior, skill, and commitment differentiated among three classes of participants: Category 1, 2, and 3 racers. Specialization dimensions were also used to predict participants’ subjective progression in participation over the past five years and next five years. Relationships between specialization dimensions and subjective measures of progression differed with endurance skill and personal commitment being most significant. This study provides insight into the dynamics of progression, particularly in outdoor activities where objective performance standards exist.     

传统山地建筑的生态价值评析——以滇南彝族土掌房为例

在当今全球低碳经济视野下,生态建筑已然成为建筑设计的一种必然趋势。而如何将传统建筑的生态价值合理的发掘、改进并创新,然后运用到现代建筑设计中,这更是值得我们去认真探讨的。通过对滇南彝族传统民居土掌房的生态价值分析和评价,总结出了土掌房的生态优势对现代山地建筑的借鉴意义,以此来为生态建筑设计提供设计思路。     

基于环境偏好的旅游者山地度假环境期望分异——以湖南武陵源为例

山地度假环境问题是山地度假旅游开发的重要方面,研究意义重大。基于度假环境的偏好划分湖南武陵源旅游者的类型,探索其山地度假环境期望的差异,寻求度假环境偏好对期望的影响。利用聚类分析方法将旅游者分为高度假环境偏好型、低度假环境偏好型两类。结合独立样本T检验,揭示其对度假环境期望的差异,最后据此提出了张家界武陵源发展山地度假旅游的建议．     

中国寺院名茶经济与文化

我国历史名茶大多出自名山寺院,名茶产于名山寺院有着深厚的社会经济背景,包括具有相对充裕的土地、劳力以及稳定的消费需求条件。寺院与名茶相辅相成,经历了长期的发展过程,并形成了寺院名茶生产与生活的自身特点。由于寺院名茶的发展,从而对于寺院经济及其整个佛教事业都产生了积极而深远的影响。我国的寺院经济以丛林经济为主,名茶生产更为普遍以至于持续发展到今天的规模与水平,这一切是与寺院名茶生产的经济背景密切相关。     

西北地区山地古建筑选址因素浅议——以甘肃兰州五泉山古建筑群选址为例

地处甘肃兰州地区的五泉山古建筑群由明清时期所建佛教建筑、道教建筑、儒家建筑构成,集中体现了西北地区山地古建筑特点,成为西北地区山地古建筑选址营建的代表。通过对五泉山古建筑群的研究,分析出该类古建筑选址营建的主要形成因素,为西北地区山地古建筑群的保护与发展等问题提供基础资料与理论支撑。     

隧道真三维数值模拟

很多学者采用数值模拟的方法分析隧道开挖问题,但往往是用平面模型或者未考虑山体地貌的假三维模型,这往往不符合隧道开挖的实际情况,造成了分析结果与隧道的真实情况有很大的误差。文章根据山体地貌特征,建立了考虑山体地貌的真三维地质模型,并在此基础上进行了开挖分析,得出了更准确的结果。     

低丘缓坡土地开发利用适宜性分析与评价

本文从土地适宜性评价体系入手,通过选取评价因子,构建评价模型,进而运用GIS的空间叠加分析功能,对云南省昆明市晋宁县低丘缓坡土地开发利用适宜性进行了综合分析评价。该评价结果可以为科学合理的进行低丘缓坡土地开发提供依据。
