通过探讨流域生态环境需水量概念及分析方法,概算了石羊河流域河流基础生态环境需水量、河流输沙需水量、流域湖泊湿地生态环境需水量和下游地下水合理补给需水量。结果表明:石羊河流域河流系统基础生态环境需水量为2.458 6×108m3,约占流域地表水资源来水量的16.93%;输沙需水量为5.30×108m3;流域湖泊湿地需水量为1.53×108m3,下游地下水补给需水量为1.758 6×108m3。生态环境需水量整合后,适宜的生态需水量约占水资源总量的36.49%~48.60%。

生态环境需水量是当前水资源管理等学科研究的重点和难点。对于河流生态环境需水量已形成比较系统的理论和计算方法,但对于其它生态系统则没有固定的计算模式,生态需水量项目也因具体环境而异。依据黄河三角洲自然保护区生态系统特点,其需水量项目主要有植物需水量、湿地蒸散量、土壤需水量、野生生物栖息地需水量、补给地下水需水量和防止岸线侵蚀及河口生态环境需水量等。遥感技术在区域资源环境研究方面具有极大优越性,本文利用遥感技术重点对黄河三角洲湿地生态系统需水量中的蒸散量进行了计算,其它需水量项目则用一般方法进行了计算 ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Emerging applications of large language models in ecology and conservation science
Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...
