Study on the response of seedling regeneration to light environmental heterogeneity in Hexi south subtropical rain forest, Fujian [PDF]

open access: yes, 2005
本研究主要针对南亚热雨林天然分布树种白楸(Mallotuspaniculatus)、枫香(Liquidambarformosana)、木荷(Schimasuperba)、薄叶润楠(Machilusleptophylla)和红栲(Castanopsishytrix),从生理、形态和种群等几个层次研究幼苗更新对不同光照强度响应的机制,以期为理解南亚热带森林更新、物种多样性保持和生态恢复提供一些理论依据。采用透光率分别为100%(L100)、25%(L25)和8%(L8)的遮阴棚研究枫香、木荷 ...

Five Frontiers for Science and Practice of Ecosystem Restoration in East African Forest Landscapes 东非森林景观生态系统恢复的科学与实践:五大前沿

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 534-545, December 2025.
Implementing ecosystem restoration remains challenging for policymakers and practitioners. Focusing on Rwanda, we used a participatory world‐café approach involving scientists, practitioners, and decision‐makers working on ecosystem restoration to identify emerging challenges and future research priority areas. We identified five critical frontiers for

晋西黄土区长期人工林恢复对土壤水分和养分性质的影响

open access: yesShuitu Baochi Xuebao, 2022
黄土高原地区是我国水土流失和环境问题严重的地区之一,人工植被恢复可以有效改善土壤性质,提高土壤质量,明确长期人工植被恢复后土壤水分和养分性质的响应差异,有利于进一步有效改善生态环境。选取晋西黄土区自然恢复的次生林地、人工刺槐林地、人工油松林地3种典型植被恢复类型为研究对象,通过测定土壤物理性质以及有机碳、氮磷钾元素含量等土壤养分,对比分析长期不同人工林恢复条件下的差异。结果表明:(1)次生林地、刺槐林地和油松林地在0-20 cm浅层土壤的容重分别1.15,1.04,1.06 g/cm3 ...

Finding floral and faunal species richness optima among active fire regimes

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

Quantifying Payment Criteria of Hydropower Development for Watershed Ecosystem Services ---- Case Study of Jiulong River Watershed [PDF]

open access: yes, 2010
水电资源传统上被认为是完全绿色清洁的能源,但随着认识的全面和深入,水电资源开发与流域生态环境保护的冲突日益受到关注;流域生态补偿机制作为应对流域性环境问题的一种制度安排,正成为研究和实践的热点;但是将生态补偿应用于水电资源开发的决策和管理过程的研究还不多见。本文以水电资源开发的生态补偿为研究对象,具有重大的现实意义和应用价值。 补偿标准的确定是生态补偿机制的关键问题,也是学界争议最大的问题之一。本文围绕“水电资源开发生态补偿标准的量化方法”这一主题,开展了“理论—方法—实践”的深入研究 ...

Vulnerability of tropical fish communities across depth in the central Indian Ocean

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

基于大数据平台的城市灾害社会恢复力指标初探——以“莫兰蒂”台风为例 [PDF]

open access: yes, 2018
气候变化导致许多灾害的发生频率加快,破坏强度增加,提高城市的韧性是当前应对气候变化的重要途径。作为韧性的核心内容,社会恢复力对于灾后恢复评估及灾害的社会影响评估具有重要意义。本文以大数据为背景,关注公众心理恢复,探究反映社会恢复能力的指标及其与受灾情况之间的关系,对厦门市展开了实证分析。研究结果表明:厦门市的公众心理恢复时间最长,三明市最短;公众对莫兰蒂台风的关注度与其登陆的时间和地点有关,随台风在时空上的逼近而增高 ...

Coexistence and habitat restoration planning for the reintroduction of Spix's macaw

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Spix's macaw (Cyanopsitta spixii) is one of the world's most endangered species. Native to the Caatinga of northeastern Brazil—a region marked by significant socioeconomic vulnerability—the species was considered extinct in the wild in 2000. A reintroduction project, however, returned it to its natural habitat in 2022. The long‐term success of
