Imaginative geographies engage with the understanding and experiencing of place and place‐based social and cultural specificities through a process of re‐creation and reproduction. In this article, we explore the imaginative geographies of Lugu Lake, a tourist destination in China's Yunnan Province, and of the Mosuo people, the local minority which practices a unique marriage system. We investigate how Mosuo society has been imagined in popular discourses and representations through two cultural labels: matriarchy and free sex. We also discuss how the imaginative geographies of Lugu Lake have restructured the encounters between the local people, especially the young men, and the incoming tourists in the context of tourism development. We interrogate the complex processes of identity formation in which both the tourists and the indigenous people renegotiate and reconstruct their cultural identities within various inside–outside connections and interactions. Our central argument is that the sex encounters between tourists and the local Mosuo are conditioned by popular imaginative geographies of the sexual practices of the Mosuo. But the encounter in tourism between the gazer and the gazed also accommodates complex identity formations and the renegotiation of social relations. The empirical observations are twofold: first, the locality of Lugu Lake has been reproduced with folk and tourist imaginative geographies into an erotic frontier of free sex; second, we also argue that the geographical imagination in this case is a reciprocal process which involves the local Mosuo's renegotiation of place‐based identity, in a pursuit of imagined progress and modernity.  相似文献

China has a long history of sheep husbandry, and has several indigenous sheep breeds. However, the exact geographic origin of Chinese domestic sheep remains unclear. To provide valuable genetic information for origin of Chinese domestic sheep, we performed an ancient DNA study on 22 sheep excavated from four Bronze Age archaeological sites in Northern China. Two lineages (A and B) were observed in ancient Chinese sheep, of which lineage A was predominant reaching a frequency of 95.5%. Furthermore, phylogenetic network showed that the most frequent haplotype in ancient sheep was the founder of lineage A. These results suggest that Lineage A may hold the key to understanding the origin of Chinese domestic sheep. Sequence sharing and principal component analysis showed that the ancient Chinese sheep had a close affinity to modern Chinese sheep. However, there was no significant breed structure among three modern Chinese sheep groups, making it difficult to determine their relationship to ancient Chinese sheep. Lastly, our results imply that ancient DNA analysis could provide a new way to investigate prehistoric East-West contact.  相似文献

《肇域志》是顾炎武的地理名著 ,但流传甚稀 ,一般人很难见到。本文从四个方面对该书进行全面评价。一、从《肇域志》引录的资料 ,探讨该书的资料来源。二、通过《肇域志》与《读史方舆纪要》的比较 ,说明它们都是以历史军事地理为特点的巨著。三、《肇域志》虽经顾氏多次补充和修改 ,留待处理的痕迹仍随处可见。该书是一部未定稿。四、《肇域志》版本的流传线索及保存情况。  相似文献
