Assessment Research of Coastal Ecosystem Carrying Capacity: a Case Study in Guangxi Coastal Area [PDF]
海岸带自然资源充足,环境条件优越,支撑着沿海地区社会经济发展。然而,海岸带由于受到来自陆域和海洋的强烈相互作用,成为了最易受到环境影响而变化的生态敏感区和脆弱性较强的生态系统。相比自然的影响,人类活动是海岸带生态系统受到的最主要干扰源。随着近年来海岸带地区人类开发活动强度的持续增加,海岸带出现了资源日渐匮乏、环境质量下降、生态风险升高等一系列问题,海岸带生态系统呈现出一定的退化趋势。开展海岸带生态系统承载力评价研究,有利于协调自然、经济、社会之间的发展关系,为制定合理的海洋发展战略提供科学依据和技术支撑。

Threats to and management of Natura 2000 protected areas relative to agricultural practices
Abstract The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation.

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
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

The Study of Original Ecological Landscape Regeneration Design Under theVisual of the Land Art——Xiamen Huandao Road [PDF]
目前,全球正面临着经历一场声势浩大并将持续下去的生态变革。人类时刻关注着环境问题(生态污染、全球变暖等)、社会问题(人性冷漠、交流障碍等)、文化问题(信仰缺失、文化断层等)与能源危机等现实问题。而在生态变革之中,真正的挑战是将现有资源进行修复与再生,以便更好的分配与使用。在信息爆炸的当下,各界人士针对生态问题给出了相应的解决方案,重塑生态系统、人文景观的再造与再生循环系统设计作为主要的三种方案,在实践中收到积极的效果。近年来,艺术家也参与到这一时代洪流中,摒弃无作为的个人创作,承担起更多的社会责任 ...

Lessons from an eradication under multiple constraints of an island rat population of record density
Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

A link between increased temperature and avian body condition in a logged tropical forest
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.
