Shuitu Baochi Xuebao, 2005 湿地生态用水是湿地为维持自身发展过程、保证基本生态功能发挥所需要的水量,作为一种特殊的生态系统类型,湿地的生态用水计算比其他生态系统复杂,其中包括湿地植被需水量、满足蒸发需水量、湿地土壤需水量、湿地动物需水量、野生生物栖息地需水量以及景观建设需水量等等。本文介绍了用水量平衡法计算湿地生态系统需水的方法,并分别探讨了湿地中植被、土壤、生物栖息地等诸项生态需水量的计算方法。用这些方法对乌梁素海湿地的生态用水量进行了具体探索。乌梁素海湿地包括内蒙古自治区的第二大淡水湖———乌梁素海及其周围的沼泽地 ...

World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Gongye shui chuli, 2009 对3种不同内部结构的潜流湿地的特性进行了研究。示踪试验的结果表明,3种湿地的HRT为:垂直折流湿地>水平折流湿地>常规湿地。在试验条件下,常规湿地对CODCr、NH4+-N、TN、PO43--P的去除率分别为76.5%、56.6%、54.4%和93.1%;水平折流湿地相应的去除率分别为88.8%、72.6%、65.8%和96.9%;垂直折流湿地相应的去除率分别为94.1%、82.6%、79.2%和99.6%;对4种污染物的去除效果均为:垂直折流湿地>水平折流湿地>常规湿地。

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Moist‐electric generators (MEGs) harness energy from ubiquitous ambient humidity, which has emerged as a promising way to collect energy irrespective of location and time. This study presents a high‐performance MEG employing a bilayer Janus nanofiber membrane: a hydrophilic layer (lithium chloride/citric acid/polyvinyl alcohol) for enhanced ...

野生动物学报, 2005 中国是湿地大国,湿地面积居亚洲第一位,世界第四位,湿地总面积约为6594万公顷。截止到2000年,建立湿地保护区289处。湿地是地球上三大生态系统之一,与森林和海洋相比,湿地生态系统更加脆弱,与人类的发展关系更为紧密,其功能和价值的社会化程度体现得更为充分。由于湿地的概念提出较晚,湿地类型保护区的管理工作起步较迟,我国大部分湿地保护区的管理均相对落后,社会化程度普遍较低。本文力求分析湿地、湿地资源和湿地保护区的社会属性,从湿地保护区主体和客体的特点和问题入手 ...

Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...

Bright spots for advancing ecological understanding and conservation decision‐making
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract A lot can be learned by studying bright spots—defined as unexpected positive outcomes. In fields like public health, education, and oncology, identifying factors behind bright spots reveals previously unknown drivers of success that can be replicated elsewhere.

Æ E Æ Å – Reshaping the Role of Træna Fishermen
, 2022 This diploma project aims to strengthen the viability of Træna’s community by proposing an ocean research facility in the archipelago, enabling the next generation of local fishermen to collect oceanographic data while working at sea. The idea of the fisherman as oceanographer is inextricably linked to the architectural program on the island of ...

Integrative Conservation, Volume 4, Issue 3, Page 430-441, September 2025.Our study identifies southern China, including mountainous regions and islands, as key areas rich in phylogenetic diversity, and phylogenetic endemism of lizards that are currently under‐protected. Current protected areas however do not adequately cover regions that are critical for preserving the evolutionary history of lizards.
