Marine Ecological Damage Assessment and Compensation: Theory, Approaches and Case Studies [PDF]
, 2015 海洋生态系统是地球生命支持系统之一，也是支撑人类生存和发展的重要资源宝库，对于人类经济的繁荣和生活质量的提高贡献巨大。然而，随着人类对海洋开发进程的加快，海洋环境与海洋生态系统面临着越来越大的压力，海洋资源利用冲突、海洋环境质量退化和生态破坏问题日益凸显。建立海洋生态损害补偿机制被认为是解决海洋资源利用冲突，保护海洋环境和生态系统永续发展的有效途径之一，而海洋生态损害补偿理论和方法的研究则是其重要的前提。目前，生态补偿的研究与实践多集中在陆域生态系统，涉海方面的研究尚不多见 ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico
Conservation Biology, EarlyView.Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

Method and Practice in Setting Coastal Construction Setback Line: A Case Study in Longhai [PDF]
, 2016 海岸带地区由于其富饶的资源、优美的环境、优越的地理位置和独特的海陆性质，使其成为人类活动最密集和最活跃的区域。然而人类为了享受海岸带地区为其生存和发展带来更大的经济利益，一方面越来越多的建筑物和基础设施出现在距海岸线更近的地方，海岸侵蚀以及自然灾害已经严重的威胁到沿海地区人类生命财产的安全；另一方面由于人类活动的加强，海岸带的生态系统遭到破坏，生态环境日趋恶化。如何协调海岸地区的和谐发展，实现海岸带经济发展的可持续性已经成为当今社会最关注的热点问题之一 ...

People and Nature, Volume 8, Issue 1, Page 225-237, January 2026.Abstract Water‐related ecosystem services (WES) provided by urban rivers are influenced by complex interactions between social and ecological systems. Understanding the public perception of WES is crucial for sustainable planning and management of urban rivers in the future. Although studies on public perception on WES have been growing in recent years,

Land Use and Land Cover Change and its Ecological Response during 1992-2011 in Karachi, a Coastal City of Pakistan [PDF]
, 2015 土地利用覆被变化（LUCC）是生态环境变化的一个重要因素，它还是人类活动与世界环境变化之间的一个很好的参照。土地利用覆被变化是由不同的自然因素造成的，其他一些人类活动也改变了土地覆盖状况，并产生严重的影响以至于限制了人类生产，破坏环境健康和生态系统服务与功能。分析土地利用变化的时空特征对于理解和评估城市化带来的后果是至关重要的。 本研究基于遥感与GIS技术，采用回溯分类方法生成了1992、2001和2011年的卡拉奇市土地利用地图。在此基础上，应用强度分析方法分析了卡拉奇市1992 ...
