Effect Assessment of Marine Ecological Restoration：A Case Study of Sansha Bay [PDF]
, 2016 由于人类对海洋资源的无序开发，海洋生态系统面临着环境恶化、结构失调、功能衰退等诸多问题，并逐渐制约海洋的可持续发展。海洋生态修复作为当前缓解生态系统退化压力、恢复受损生态系统结构功能的重要手段，是海洋生态系统管理的核心内容之一。但目前针对海洋生态修复的研究大多以针对单一生境的修复技术措施为主，缺乏对海洋生态系统各组分综合修复的系统研究，对如何评判海洋生态系统修复的效果，更是关注甚少。科学合理的对海洋生态修复实践进行评价，可以及时掌握生态系统对人工修复的响应和反馈 ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, EarlyView.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

闽北山区红壤丘陵开发地生态恢复与综合利用模式构建及其应用研究
Shuitu Baochi Xuebao, 2006 山地生态系统的退化不仅是一个生态问题，也是一个经济问题。生态恢复重建不能仅仅就环境退化问题而开展生态功能的恢复重建，却而不去考虑经济恢复重建和区域脱贫与持续发展问题。根据红壤丘陵开发地退化成因分析和区域社会经济文化状况，建立了以水土保持为核心，“林果草牧沼菌”有效链接的治理模式，以草保土养地，以草带动地方产业发展．实现生态恢复与经济发展的双赢。

The Resistance Research and Application of Typical Plants for Island Vegetation Restoration [PDF]
, 2016 植被是海岛生态系统的重要组成部分，海岛植被修复对加快恢复受损的海岛生态环境，改善海岛居民的生活生产条件起关键作用。目前，我国大部分海岛生态破坏比较严重，而海岛植被修复工作起步较晚，海岛植被修复技术还不完善，对环境恶劣海岛植被修复依然缺乏良策。本文依托平潭海岛景观生境修复技术研究与示范项目，以木麻黄（Casuarinaequisetifolia）、夹竹桃（Neriumindicum）和台湾相思（Acaciaconfusa）为实验材料，室内人为控制干旱胁迫、根系盐胁迫和叶片盐胁迫的程度及时间 ...

A link between increased temperature and avian body condition in a logged tropical forest
Conservation Biology, EarlyView.Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.
