正《中华人民共和国国民经济和社会发展第十四个五年规划和二〇三五年远景目标纲要》提出的"实施生物多样性保护重大工程,构筑生物多样性保护网络",明确了新时期我国生物多样性保护的工作任务。2021年4月,我国《生物安全法》的正式实施也反映出生物多样性保护在国家安全体系中的重要地位。联合国《生物多样性公约》第十五次缔约方大会今年10月也将在昆明举行,反映出我国生物多样性保护与生物安全治理工作的国际影响力与话语权的提升。当前,我国生物多样性保护除了需要以保护物种、 相似文献

生物多样性保护领域中的国际条约设有知识产权条款,知识产权条款发挥鼓励创新的基本功能。现有生物多样性利用中存在的知识产权问题集中在获取和惠益分享、遗传资源公开和利用知识产权产生的利益三方面。随着数字开源运动和数据库的大量兴起,协调型知识产权规则因缺乏强制力,使知识产权条款发挥的效力大打折扣。加之知识产权的专有属性和产业化,使得知识产权和多样性保护之间的冲突加剧。中国积极参与生物多样性保护全球治理,由被动参与者转换为积极推动者,确认和实施知识产权规则,关注数字序列信息的发展并加强农民权利的表达。 相似文献

保护生物多样性不仅关乎人类的生存和发展,而且是方方面面的需要。保护生物多样性的方法有多种,可持续利用是原地保护、迁地保护之外的又一种重要的保护方式。在经济建设过程中,既要保护生物多样性,又要发展地方经济,是一件极难做到的事。在重大工程项目实施之前,环境评价工作如果能够做得很好,就能较好地协调发展与保护的矛盾。中国保护生物多样性将为世界保护生物多样性做出巨大的贡献,它的成功经验可供其他国家借鉴,有利于世界生物多样性的保护和维持。 相似文献

Microcosm studies on anaerobic phosphate flux and mineralization of lake sediment organic carbon 总被引:1,自引:0,他引:1
Lake sediment has long been recognized as an important source of nutrients such as phosphorus. To gain a better understanding of phosphorus flux at the sediment-water interface, it is crucial to investigate the sediment porewater. There is also growing concern and interest in identifying whether organic-rich sediment is an important source of greenhouse gases such as CO(2) and CH(4). In the present study, we took sediment samples from West Lake, a shallow hypereutrophic lake in Hangzhou, Zhejiang Province, China and incubated subsamples under anaerobic conditions at 25 degrees C for 182 d using a specially designed microcosm that permits repeated extraction of sediment porewater and sampling of headspace gases. Anaerobic phosphate fluxes and mineralization of sediment organic carbon were measured. Average diffusive flux of soluble phosphorus was 0.81 mg P m(-2) d(-1) during the initial 18 d of incubation. Decomposition of sediment organic C followed zero-order reaction kinetics and methane accounted for about 50% of the mineralization products. The results suggest that organic-rich sediments can be important sources of P and methane under anaerobic conditions. Laboratory studies simulating field conditions and field studies are necessary to determine the contribution of sediment as a source of P and greenhouse gases. 相似文献

生态补偿机制在生态文明建设中发挥了重要作用。中央关于生态补偿机制顶层设计文件密集出台,生态补偿机制建设呈现出八大趋势:一是从狭义补偿拓展到广义补偿;二是从区内补偿拓展到区际补偿;三是从林水补偿拓展到土地补偿;四是从陆上补偿拓展到海洋补偿;五是从政府补偿拓展到市场补偿;六是从补偿政府拓展到补偿居民;七是从模糊补偿过渡到精准补偿;八是从单一制度演变到制度组合。完善生态补偿机制需要扫除生态环境产权界定、生态环境价值评价等技术性障碍和绩效评价不够科学、实施机制没有落地等制度性障碍。 相似文献

Capps and Lederman, in a paper published in this journal in 2015, argued that, at the time, the dismal circumstances of the Ebola outbreak in West Africa was an opportunity to revisit public health responses to emergent infectious diseases. Using a One Health lens, they argued for an ecological perspective—one that looked to respond to zoonoses as an environmental as well as public health concern. Using Ebola virus disease as an example, they suggested shared immunity as a strategy to vaccinate both humans and great apes. Since then, vaccination as a conservation strategy in this case has been debated and at least one great ape vaccination trial has been proposed: some, however, are less convinced of the ethical arguments to pursue vaccinating wild animals. Using this opportunity, we review Capps and Lederman’s arguments and directly respond to the plausible objections to them. 相似文献

Reexamining the relations between socio-demographic characteristics and individual environmental concern: Evidence from Shanghai data 总被引:1,自引:0,他引:1
This study reexamines the influence of socio-demographic characteristics on individual environmental concern by applying a pooled sample of 1200 individuals in Shanghai, China. Previous studies, which made efforts to explain environmental concern as a function of social structure, suggest that there are traditionally five observations (the age, gender, social class, residence, and political orientation effects) for the relations between socio-demographic characteristics and individual environmental concerns. In this study, we first conduct a factor analysis to a group of 11 environmental concern measures and then use the resulting factors to test three observations (the age, gender, and social class effects) by applying a seemingly unrelated regressions (SUR) model. As a result, high household income and high education level have reacted positively to environmental concern as expected. However, we find that in contrast to most of the previous studies, age has shown positive reaction to individual environmental concern, implying that the older generation is more concerned about the environment than the younger population. In addition, the SUR results indicate that women in Shanghai seem less concerned about the environment than men. Other socio-demographic characteristics such as employment status and household size are found to be almost irrelevant to environmental concern. 相似文献
