摘要: 保护优先区系统判识是实现生物多样性高效保护的关键途径之一。云南处于全球生物多样性热点地区,还未见陆栖脊椎动物保护优先区规划研究,且已有研究仅评估了自然保护区的保护状况,而对其他保护地类型的认识还非常有限。本文以保护物种为指示对象,首先应用物种分布与系统保护规划模型判识出陆栖脊椎动物保护优先区;然后,通过与3个已有保护优先区图层对比分析,研究陆栖脊椎动物保护优先区的空间分布格局;最后,评估了6种已建保护地类型对保护优先区的保护状况。结果表明:(1)按照17%和31%的面积保护目标,判识出的陆栖脊椎动物保护优先区主要分布于滇西北、滇西南、滇南和滇东北及沿国界边境地区;(2)31%目标下的陆栖脊椎动物保护优先区与3个已有保护优先区图层的重叠面积比均在44%以上,同时陆栖脊椎动物保护优先区也识别出大量不重叠的优先区域;(3)17%和31%目标下,保护优先区的自然保护区覆盖率分别为14.11%和11.39%,而全部6类保护地的覆盖率上升为24.01%和20.95%,说明其余5类可持续利用型保护地(风景名胜区、森林公园、湿地公园、地质公园与水源地保护区)能够极大地提升保护覆盖率,填补保护空缺。本研究能够为云南省正在实施的“以国家公园为主体的自然保护地体系建设”工作提供数据与方法支持。

Abstract: The systematic identification of priority conservation areas (PCAs) is one of the key and costeffective approaches for biodiversity conservation. Yunnan, as a global biodiversity hotspot, still lacks planning studies on PCAs for terrestrial vertebrates. Past studies only assessed the protection coverage of nature reserves, with less information on other categories of protected areas (PAs). Here, we first used protected species as surrogates and the models of species distribution and systematic conservation planning to identify PCAs for Yunnan’s terrestrial vertebrates. We examined the spatial distribution pattern of terrestrial vertebrate PCAs by comparing the results obtained with three portfolios of PCAs developed in previous studies. We finally assessed the protection coverage of PCAs provided by six different categories of PAs. The results showed that: (1) PCAs for terrestrial vertebrates based on both conservation targets of 17% and 31% Yunnan’s land were primarily distributed in northwestern, southwestern, southern, and northeastern Yunnan as well as regions nearby national borders. (2) PCAs under the 31% target had >44% of its total area overlapped with each of the three PCA datasets defined by previous studies. Meanwhile, terrestrial vertebrate PCAs also identified many new priority areas. (3) Under the 17% and 31% targets, the established nature reserves covered 14.11% and 11.39% for PCAs, respectively, whereas the coverage was increased to 24.01% and 20.95% when all six PA categories were considered. This result indicated that the remaining five sustainable use categories of PAs (i.e. Scenic Spots, Forest Parks, Wetland Parks, GeoParks, Drinking Water Source Conservation Areas) can greatly increase the protection coverage and fill the conservation gaps in Yunnan. This study could provide data and method support for the policy on establishing a new “PA System with National Parks as Its Mainstay” in Yunnan.
