Shuitu Baochi Xuebao, 2006 生态系统服务价值的研究是目前生态学研究的热点之一。本文应用Costanza生态系统服务价值计算公式，采用谢高地等人的中国陆地生态系统单位面积生态服务价值表，分析了1988-2004年武汉市土地利用的时空变化，并计算由此导致的生态系统服务价值及其结构的时空变化，结果发现：①1988～2004年，武汉市土地利用变化的热点地区和总ESV变化的热点地区都主要集中在城郊区。②1988-2004年，武汉市总ESV增加了，但生态系统服务价值结构变化较大，生态系统提供某些单项服务的功能相对减弱。③1988-2004年 ...

Taxonomic and functional diversity of urban bees of the world
Conservation Biology, EarlyView.Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Shuitu Baochi Xuebao, 2003 黄土高原在环境脆弱与经济发展低下的双重胁迫下，如何探索既适合环境保护又适应当地经济发展需求的战略对策至关重要。以黄土高原生态系统服务价值分析为基础，提出了该地区以农户单元、流域单元和区域尺度的生态系统服务恢复与重建对策。研究表明，尽管长期以来被人们所忽视，在生态环境脆弱区的生态系统服务价值依然是客观存在的，但是这些服务功能远不足以维持系统的自我循环，导致生态环境恶化趋势日趋严重。为此，必须科学分析该地区生态系统服务的现状与不足，并采取科学合理可行的生态系统恢复对策 ...

How much biotic nativeness matters across human demographic groups
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...
