饲养的“野生动物”究竟该不该吃?这是笔者在大学选修课《环境与发展》课堂上为同学们出的一个讨论题。这个题目不仅引起了大学生们的激烈争论,也受到笔者所在教研室教师们的重视和积极参与。当然,这个题目的确定也并非是笔者主观臆断或者凭空想象杜撰出来的,而是现实中普遍存在着的易被忽视的一种社会现象。报纸不止一次地刊登过,笔者也不止一次地在酒店见到有“中华鲟”出现在展品台上,问起缘由,答曰,这是自己饲养的,或者是从养殖场买来的,当然可以吃。不仅中华鲟,扬子鳄也不免同样的命运。据说,每斤鳄肉可卖到500元,每盘鳄肉炒菜竟然卖到… 相似文献

为了保护和拯救我国珍稀、频危的野生动物,发展和合理利用野生动物资源,维护生态平衡,1988年11月8日,由全国人大常委会四次会议审议并正式通过了我国第一部野生动物保护法。它包括总则、野生动物保护、野生动物管理、法律责任和附则等共五章四十二条,本法将于1989年3月1日起施行。《中华人民共和国野生动物保护法》是继《环境保护法》,《森林法》、《草原法》、《矿产资源保护法》等之后公布的又一部保护自然资源和生态环境,制止乱捕滥猎,特别是珍、稀野生动物资源,促进野生动物资源的保护、驯养科学研究及合理开发将是一部重要的法律武器。四川是全国最大的省自然保护区较多,特别是闻名世界的珍、稀频危野生动物国家一级保护的大熊猫、金丝猴、中华鲟等是人类开展科学研究、文化交流、经济开发等重要的物质资源。本刊这期为扩大宣传这一重要法律的目的、意义和内容,全文刊载,希望环保、林业、水利、渔业等行政主管部门积极重视广为宣传,身体力行,并建议四川省人大常委会尽快根据本法精神和我省野生动物资源情况制定完善、有力、可行的具体实施办法,以保证本法律的有效实施。 相似文献

针对炼油装置所产生的危险废物"三泥"的减量化处理要求,延迟焦化装置引进"三泥"雾化智能喷雾系统。文章通过指出生产现状及存在的问题,分析了"三泥"雾化智能喷雾系统的原理及"三泥"雾化的工艺流程。实践表明,通过"三泥"雾化装置将"三泥"打进焦炭塔,在保证石油焦质量的同时,提高了"三泥"处理量,降低了"三泥"排放量,降低了蒸汽消耗,从而大幅降低了"三泥"处理成本。实践证明延迟焦化协同处理"三泥",是当前"三泥"减量化最有效的手段之一。 相似文献

中国文房有"笔墨纸砚"之说。砚虽然在四宝中排位最末,其地位却一直居领军。所谓"四宝"砚为首,砚台因为质地坚实、能传百代,所以现今社会上"四宝"以砚最为多见,受人喜爱的范围也最为广泛。如今的拍卖市场中,"文房"有广阔的市场。而所有的"文房"拍卖,几乎都是砚台为主导。文房四宝中,除了"宣纸"、"徽墨"、"湖笔"为人所知,其他的"笔墨纸"世人知者甚少。唯独砚台,不仅"四大砚台"声名远播,更有无数地方砚种流派纷呈。"砚文化"更成为显学。 相似文献

During the past 25 years the bauxite and alumina industry has grown threefold creating major change in the industry structure and reducing the dominance of the majors. Australia has emerged as the leading producer with a major third party alumina market developed principally by Alcoa of Australia. Future growth while, less dramatic, is likely to be substantial requiring US$50 billion to fund new projects which will be concentrated in developing countries with large bauxite reserves and developed infrastructure. 相似文献

ABSTRACTSmart and eco-cities have become important notions for thinking about urban futures. This article contributes to these ongoing debates about smart and eco-urbanism by focussing on recent urbanisation initiatives in Asia. Our study of India’s Smart Cities Mission launched under the administration of Narendra Modi and China’s All-In-One eco-cities project initiated by Xi Jinpin unfolds in two corresponding narratives. Roy and Ong’s [2011. Worlding Cities: Asian Experiments and the Art of Being Global. Oxford: Wiley-Blackwell] “worlding cities” serves as the theoretical backdrop of our analysis. Based on a careful review of a diverse set of academic literature, policy and other sources we identify five process-dimensions for analysing the respective urban approaches. We show how the specific features of China’s and India’s urban focus, organisation, implementation, governance and embedding manifest both nations’ approaches to smart and eco-urbanism. We argue that India’s Smart City Mission and China’s All-in-One project are firmly anchored in broader agendas of change that are set out to transform the nation and extend into time. The Indian Smart City Mission is part of a broader ambition to transform the nation enabling her “smart incarnation” in modernity. Smart technologies are seen as the key drivers of change. In China the framework of ecological civilisation continues a 5000-year historical tradition of civilisation excellence. By explicitly linking eco-urbanism to the framework, eco-cities become a means to enact ecological civilisation on the (urban) ground. 相似文献

The success of river and lake basin development and management is rooted in the knowledge of its resources, both physical and human. Within the framework of an integrated basin plan, each economic sector depends on the adequacy of such data for its individual development. The management and conservation of the basin itself in turn depends on knowing the requirements of those sectors and their probable impact on each other and on the status of the basin's resources, its ecology and environment. The development of African river basin resources is subject to various constraints, some for physical and climatic reasons, others tied to socio-cultural characteristics and the priorities of national economies. These are reflected in financial, manpower and institutional limitations, problems of finding technologies suited to specific local conditions and concern for human health. The scale and complexity of river basin development make it difficult to predict precise outcomes of planned proposals, but a progressive approach which links long-term activities with achievable, shorter term production projects offers prospects for ultimate success. 相似文献
