建立保护区是防止不可逆转的生物多样性丧失的主要目标和工具。然而,一段时间以来,针对特定物种的保护区的有效性一直受到质疑,因为针对关键物种进行保护可能会损害物种多样性的整体区域库,而系统发育和功能多样性很少得到考虑。本文根据2279种陆生脊椎动物的分布区和亲缘关系,对中国保护区保护系统发育多样性的有效性进行了评估。系统发育多样性和分类多样性之间存在强烈的正相关,目前只有12.1%-43.8%的优先保护区受到保护。然而,物种丰富度加权时,系统发育多样性的格局和覆盖度的影响。这些结果表明,在中国,以高物种丰富度为目标的保护区总体上很好地保护了系统发育多样性,但在一些具有更多独特或受威胁群落的地区(例如,中国东部沿海地区,那里受到严重威胁的鸟类群落保护较少)。我们的研究结果表明,目前的保护区分布可以改善,虽然大多数保护区保护分类和系统发育多样性。
Establishing protected areas is the primary goal and tool for preventing irreversible biodiversity loss. However, the effectiveness of protected areas that target specific species has been questioned for some time because targeting key species for conservation may impair the integral regional pool of species diversity and phylogenetic and functional diversity are seldom considered. We assessed the efficacy of protected areas in China for the conservation of phylogenetic diversity based on the ranges and phylogenies of 2279 terrestrial vertebrates. Phylogenetic and taxonomic diversity were strongly and positively correlated, and only 12.1–43.8% of priority conservation areas are currently protected. However, the patterns and coverage of phylogenetic diversity were affected when weighted by species richness. These results indicated that in China, protected areas targeting high species richness protected phylogenetic diversity well overall but failed to do so in some regions with more unique or threatened communities (e.g., coastal areas of eastern China, where severely threatened avian communities were less protected). Our results suggest that the current distribution of protected areas could be improved, although most protected areas protect both taxonomic and phylogenetic diversity.
