对园林围墙与园路进行设计与施工的分析

在黑暗的大海深处,并非一些人所想象的,是海洋中的荒漠,也非一些人所想象的,是大型怪物的藏匿之地,那里生活着不少鲜为人知的小型海洋生物,它们大多具有艳丽的外表和高雅的姿态,堪称大海深处的装饰品。     

地球上有多少种生物

你知道地球上究竟有多少种生物吗?或许不少人会说,大约几十万种吧。而联合国环境署最新发布的一份报告称,地球上共有870万种生物,其中包括650万种陆地生物和220万种海洋生物。870万种生物是个什么概念?假如我们能活100岁,假如我们从一出生就开始每天不间断地参观各种生物,那么每天需要

21世纪是人类研究、开发、利用海洋生物资源的黄金时代。从几个比较活跃的领域介绍了海洋生物中的有效成分及其提取方法。最后对有效成分的应用进行了展望。     

The impact of ocean warming on marine organisms

Since the beginning of the Industrial Revolu- tion during the late eighteenth to the early nineteenth centuries, there has been rapidly increasing release of greenhouse gases, notably CO〉 into the atmosphere. As a consequence of this atmospheric change, the Earth＇s average surface temperature has increased by approxi- mately 0.6 ℃ over the last 100 years. The rate of release of greenhouse gases continues to increase, and global surface temperature rose by approximately 0.2 ℃ per decade in the last 30 years, a rate that is greater than at any other time during the last 1,000 years. The wide-ranging effects of these increases in greenhouse gases and temperature on the biosphere are subject to intense scientific study. Much has been learned, but much more needs to be elucidated, if we are to predict how terrestrial and aquatic ecosystems will be affected by global change. This brief review focuses on the marine environment and offers a concise summary of some of the important advances in our knowledge about the impacts of global change, including physical and chemical changes of the ocean, as well as the impact of ocean warming on marine organisms. Our analysis also points out areas where critical new information is needed if we are to predict the future of marine ecosystems in a warming world with accuracy.     

我国海洋生物废弃物药用研究现状与策略

《神农本草经》《本草纲目》均有以海洋生物废弃物作中药应用的记载,用药历史悠久,现代研究同样证实海洋生物废弃物中药营养价值丰富,有巨大的药用潜力.加之我国海洋生物物种繁多,每年产生的海洋生物废弃物数量庞大,不利于海洋环境保护,因此,可采用现代科技有效利用海洋生物废弃物,发挥其药用价值.本文综述《神农本草经》《本草纲目》中...
