旅游发展驱动的少数民族建筑景观的变迁,是旅游对区域文化影响的重要表现.文章通过对九寨沟树正寨的实地问卷与深入访谈调查,分析了居民和游客对藏寨建筑景观特色变迁的感知,认为居民对藏寨建筑景观的特色并没有清晰的认识,保护没有得到重视,而游客也缺乏对真实藏族传统文化的认识.研究认为,少数民族旅游地传统民族文化的保护,重在认清民族文化的差异和精华,增强当地居民的自我认同,促进社区居民参与旅游规划和管理,培养主人意识,形成对民族文化保护和传承的自觉性;同时还需要深化旅游地的管理,以引导为主,积极应对经济水平提高以后居民对生活环境改造的合理要求.  相似文献

任何一座古建筑都可以从建筑物上追溯许多往事。建筑是技术与艺术的综合体。是各个时代人类文明的标志,是人类文化重要的组成部分。建筑具有丰富的民族文化特点。建筑文化的交流促进了世界建筑的发展,增进了各国的友谊,各国取长补短,相互促进,共同提高。要反对建筑的简单化、一律化,提倡多样化、民族化。  相似文献

The Scottish model of national parks reflects wider changes in the management of special or protected landscapes. This paper uses Ingold's dwelling conceptualisation of landscape to reflect on how material and cultural processes affect stakeholders' perceptions of the Cairngorms National Park in Scotland, UK. Important to understanding different views, is the separation, unique to the Cairngorms, of ‘the park’ from its management organisation. The paper argues that this separation creates a conceptual space for the negotiation of contested claims regarding the park. Such claims reflect not only the relationship between people and place, or as Ingold (2000) puts it, the landscape as it is known to those who dwell in it; they also represent vested interests and regimes of power concerning what happens in specific places. These claims do not reproduce simple splits between, for example, public/private or conservation/development but show a more complex picture.  相似文献

This article shows how the panorama, as a modern form of visualization and representation, became a model for the Santa Lucia Hill and the Cousiño Park, two emblematic projects of Santiago's transformation, carried out by Benjamín Vicuña Mackenna between 1872 and 1875. On the one hand, supported by the height and location of the hill and its pattern of paths and terraces, the Santa Lucia promenade became an effective mechanism for visual control of the city as a whole, as well as a reference to the new urban order that was to be imposed. On the other hand, by proposing a landscape design that served as an urban window into Santiago's geographical surroundings, the Cousiño Park project interpreted the qualities of the panorama from a strongly local sensitivity that highlighted the values of life in contact with nature. The analysis of these two cases will show how the panorama remarkably influenced Santiago's first transformation in the republican era, while representing fundamental values of the emerging national identity.  相似文献

Industrial esthetic designers typically produce hand-drawn sketches in the form of orthographic projections. A subsequent translation from 2D-drawings to 3D-models is usually necessary. This involves a considerably time consuming process, so that some automation is advisable.  相似文献
