人类学民族学硕士研究生培养经验五人谈

从20世纪90年代中期开始,中国的硕士研究生教育已从精英教育转换为普及教育、素质教育。适应这种变化,人类学民族学硕士研究的工作应该强化。在增加数量的同时,不降低质量。中山大学人类学系、厦门大学人类学系、广西民族学院等单位的做法值得借鉴

ON THE REVIVAL OF RURAL CHARACTERISTIC INDUSTRY IN ARCHITECTURAL CONTEXT： A CASE STUDY OF ZI＇NI TOWN IN LONGHAI

抛开产业经济这个基础,流于建筑形式的“乡村复兴”只是空壳。本文从产业复兴的视角出发,以龙海市紫泥镇蘑菇产业为研究案例,结合当地废弃蘑菇房的改造与再利用,论述如何利用现有的空间形式和建筑手法,从生产、加工、经营等方面进行产业复兴,从而再现乡村活力。The ＂rural revival＂ of an architectural formality is only an empty shell, when it puts aside the industrial economy. From the perspective of industrial revival, this paper takes the mushroom industry of Zi＇ni town in Longhai as the research case, combining with the transformation and re-use of the local abandoned mushroom breeding room and discusses how to use the existing forms of space and architectural practices from the aspects of production, processing and management to carry out the industrial revival, so as to reproduce the vitality of the village
