人工养虾池生态系统结构特点及其控制对策

为养殖对虾而修筑的大大小小的养虾池都是一相对独立的生态系统。在池内生态条件适于对虾正常要求的情况下，对虾可以在其中生存、生长。如果生态条件逐步恶化，非但影响对虾的正常生活、生长，严重时甚至导致全部对虾死亡。粗放式的养殖，其影响也相对小些，高密度养殖情况下潜在的危险较大，对养殖池的环境状况要特别注意。ｌ人工养虾生态系统的基本特点１·１人工养殖池是一个结构简单的生态系统。在池内除放养的对虾（有时混养贝类等）外自然存在的生物通常是浮游植物和浮游动物，食物链大体上是二个层次（对虾靠投饵喂养例外）。养虾池…     

Understanding El Niño — The importance of Grey Literature in Coastal Ecosystem Research and Management

Access to information about past states of the environment and social systems is fundamental to understand, and cope with, the challenges of climate change and over-exploitation of natural resources at the onset of the 21st century. The loss of (old) data is a major threat to understanding better and mitigating long-term effects of human activities and anthropogenic changes to the environment. Although this is intuitively evident for old and local literature of any kind, even present-day international publishing of papers without the underlying raw data makes access to basic information a crucial issue. Here, we summarise experience resulting from a EU-funded International Science & Technology Cooperation (INCO) project (CENSOR) addressing Coastal Ecosystem Research and Management in the El Niño Southern Oscillation (ENSO) context. We show that indeed “Grey Literature” is still one of the most important sources of knowledge about natural science research and management of natural resource systems in Latin American countries. We argue that public archiving of original data of present-day research and old (Grey) Literature and easy public access are important for appreciating today's global environmental challenges caused by human activities, both past and present.

区域复合生态系统分析及其可持续发展对策

从系统物质循环角度分析了人类社会-经济-自然复合生态系统不可持续发展的原因是由于大量生产-大量消费-大量废弃的线性生产和消费模式耗用了大量资源，产生太多的废弃物，破坏了复合系统正常的物质代谢。提出系统调节，实现系统可持续发展的途径，包括控制人口增长，适度消费；调整复合系统生产链的数量结构和比例关系；建立协调的结构网络关系，构建循环型社会。
