Shuitu Baochi Xuebao, 2001 湿地在生态系统中的功能和价值已得到公认,但对湿地的破坏却因种种原因仍在继续.根据国际上对湿地的不同定义,讨论了湿地定义对湿地保护的重要性,同时结合我国一些地区的研究成果,指出湿地保护应以保护从陆地到水体的过渡带为主,而将水体本身以及诸如稻田一类的人工系统包括在湿地中,则会对湿地保护带来负面影响.最后根据美国不同部门对湿地水文特征的定义探讨了识别湿地水文特征的标准.

Wildlife Letters, Volume 3, Issue 3, Page 109-117, September 2025.We found that the Asian Openbill primarily roosted near waterbodies and frequently used farmland habitats, with significantly higher populations observed during the breeding season. Farmland and wetland areas exhibited a positive effect on the species' habitat use.

Shuitu Baochi Xuebao, 2008 对三江平原3种典型湿地(毛苔草湿地、小叶章湿地、岛状林湿地)的土壤酶活性、土壤养分进行了研究,探讨了不同湿地土壤酶与土壤养分及酶活性间的相关性。结果表明:不同湿地土壤酶活性和土壤养分含量有较大差异。土壤蔗糖酶、脲酶、过氧化氢酶、淀粉酶活性与土壤有机质、全氮、碱解氮含量变化趋势一致,表现为毛苔草湿地>小叶章湿地>岛状林湿地。酸性磷酸酶活性表现为岛状林湿地>毛苔草湿地>小叶章湿地;纤维素酶活性则表现为毛苔草湿地>岛状林湿地>小叶章湿地。经分析,土壤酶活性和养分密切相关,且酶活性间存在一定的相关关系,其中脲酶、

Seasonality of temperature dependence of methane fluxes from natural wetlands
Functional Ecology, Volume 39, Issue 9, Page 2383-2397, September 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Temperature dependence is a crucial parameter in estimating methane (CH4) fluxes from natural wetlands, yet our understanding of this parameter remains inadequate. Seasonal fluctuations in water levels and ecosystem productivity lead to seasonal differences in CH4 ...

Integrative Conservation, Volume 4, Issue 2, Page 188-204, June 2025.We assessed the distribution of 14 threatened agamid lizard species using Species Distribution Modeling to identify hotspots for these species' conservation. Based on the results, high‐priority areas of threatened agamids were projected to occur specially in the wet zone.

Gongye shui chuli, 2019 人工湿地脱氮与其类型有着重要联系。不同类型人工湿地的构造、运行方式及复氧能力存在差异，因而脱氮效率有所不同。复合人工湿地的脱氮效率明显优于单一湿地系统。为了克服湿地脱氮中存在的不足，近年来涌现一批新型人工湿地，通过人工增氧、固定化微生物、电化学等新技术优化湿地构造、强化湿地脱氮过程。在总结不同类型人工湿地脱氮特性的基础上，重点分析各类型人工湿地脱氮效率的差异，并对今后的相关研究方向进行展望。

Wildlife Letters, Volume 3, Issue 2, Page 56-63, June 2025.The Serra do Amolar, located in the Brazilian Pantanal, is a crucial but understudied area for biodiversity conservation. Through camera traps, we recorded 29 mammal species, including three rodent species documented for the first time in the area: Cavia aperea, Cuniculus paca, and Holochilus chacarius.
