Contribution of Different Processes in Wetland Soil N_2O Production in Different Restoration Phases of the Yellow River Estuary, China [PDF]
, 2014 采用时空替代法,选择黄河口生态恢复前后未恢复区(R_0)、2007年恢复区(R_(2007))和2002年恢复区(R_(2002))的芦苇湿地为研究对象,分析了生态恢复工程对湿地土壤N_2O产生不同过程与贡献的影响. 结果表明,尽管不同恢复阶段湿地土壤N_2O总产生量差异明显,但总体均表现为N_2O释放. 恢复区湿地土壤的N_2O产生量大于未恢复区.

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 ...

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 ...
