个旧锡业开发与生态环境变迁(1890-1949) 总被引:2,自引:0,他引:2
谭刚 《中国历史地理论丛》2010,25(1)
随着1889年蒙自的开关,尤其是1910年滇越铁路的全线通车,极大地改善了云南的对外交通运输条件,推动了个旧锡业的迅速发展。在1890年至1949年的60年间,个旧共生产大锡323042吨,个旧锡业也取代铜业成为近代云南的矿业支柱。个旧锡业在推动云南矿业发展的同时,也对个旧及周边地区生态环境产生了巨大的影响。在1890年至1949年的60年间,个旧地区仅土法炼锡就至少消耗45万吨以上木炭。个旧、蒙自、建水、开远和石屏五县地区天然林平均覆盖率从清初的90%锐减至1940年的2.98%,近三百年间减少了80%以上,个旧锡业开发显然是五县天然林平均覆盖率急剧减少的重要原因。同时,锡矿的大量粗放开采和冶炼,也污染了个旧地区的土壤、水源和空气环境,带来了环境污染问题,影响了当地民众尤其是矿工的身体健康。因此,锡业开发是导致近代个旧及周边地区生态环境变迁的重要原因。 相似文献

庾信是南北朝文学的集大成者,《哀江南赋》是他的代表作品。在《哀江南赋》中作者以史诗之笔深切描写了梁朝由盛而衰以至灭亡的全过程,抒发了个人亡国之恨、乡关之思、身世之悲。这种寓时代乱离于个人哀怨的情感内容是对赋体的一次重大开拓,史诗性和自传性是它的特色。 相似文献

ABSTRACTThe sixteenth-century account of Alexander Nyndge’s dispossession saw republication in 1615. Yet this was not a mere reprint: alterations included passages borrowed from notable puritan authors George Gifford, John Darrel, and Edward Dering, and an invitation for audiences to take the account as an example. From the 1590s, the English national church’s responses to (typically puritan) minister-led dispossessions by prayer and fasting had restricted opportunities for the godly to perform and publicize dispossessions. However, republishing the Nyndge account with alterations enabled circulation of a godly dispossession narrative adapted to a contemporary context.With limited source materials after c. 1600, historians have had difficulty assessing continuities and changes in puritan ideas about dispossession. Yet comparing the two versions of the Nyndge publication and considering how the revision fit within a post-1604 context provide a window into how views and practices were developing over the early decades of the seventeenth century. 相似文献

The paper is concerned with the ways in which ethnic culture is presented and experienced by tourists with particular reference to two villages in China inhabited by members of the Miao minority group and popular with visitors. The study is based on qualitative and quantitative data derived from primary and secondary sources and findings reveal contrasts and similarities within and between destination residents and visitors regarding attitudes to tourism and its cultural impacts, especially in terms of authenticity. While the cases display unique features, their analysis affords more general insights into the characteristics of this particular form of heritage tourism and its consequences. 相似文献

In this paper we employ a unifying approach to examine the exclusion theorem in a Weberian space under various types of uncertainty: input price or output price uncertainty, transport rate uncertainty, and technology uncertainty. The novelty of our approach is the usage of second-order conditions and comparative static analysis in the derivation of conditions for thevalidity of the exclusion theorem. Our main results are new and some are generalizations of those obtained in prior studies. 相似文献

Discussions on the politics of Chinese engagement with African development have been marked by increasing concern over Chinese use of aid in exchange for preferential energy deals. Normative liberal discourse criticizes the Chinese for disbursing ‘rogue aid’ and undermining good governance in the African continent. These criticisms not only ignore the longer‐term motivations and modalities of Chinese aid and the historical diversity of Chinese relations with Africa, but also uncritically assume ‘Western’ aid to be morally ‘superior’ and ‘more effective’ in terms of development outcomes. This paper consists of three parts. First, it will discuss the debates surrounding Chinese engagement in Africa, especially around aid and development issues. Second, the paper maps the historical development of China–Africa engagement and investigates the impacts of the changing modalities of Chinese aid with reference to case studies of two countries: Angola and Ghana. It then offers a comparative analysis of the similarities and differences between these two cases. The principal argument is that Chinese and Western donors employ different ideologies and practices of governance to conceal their own interests and political discourses in the African continent. 相似文献
