简介:随着如今旅游业蒸蒸日上发展,作为"吃住游行购娱乐"其中重要的一部分,民宿客栈、民宿、青旅、酒店的数量也是与日俱增。民俗客栈是作为客栈的高级形式出现的,它涵盖了民俗文化的传播、当地风土人情的体验等多个特点的结合体。目的是民俗客栈能更好的代表我国多民族多地区的客栈的特点和文化,它也是更容易吸引消费者的重要形式之一。方法上采用了实地考察的方式,实际考场当地的风土人情。黎族作为我国民族大家庭的重要组成部分,主要聚集在祖国的海南岛上,过去社会生产力的发展水平和其他因素的限制,表现形式也是非常质朴和简单,但在某些方面还是有明显的特点。结果经过一年的时间设计出了一套相对完整的客栈方案。结论为了传承发扬海南当地的民族风情和特殊的建筑风格,选择在海南当地进行黎族民俗客栈的设计项目,目的就是吸引更多的消费者来此地使当地特殊的建筑形式的和别致的风土人情得到更好的发扬。
