有人呼吁扩大保护区（PA），以应对持续的生物多样性丧失，但目前还不清楚未来的保护区可能有助于保护生物多样性在退化景观的保护规划原则的互补性，连通性和成本效益。我们的保护目标是在全球生物多样性热点中国西南部的喀斯特地区，将保护区网络覆盖率提高到张江流域景观的30%。Zonation 4GUI被用来评估当前保护区的充分性，并在最大限度地提高目标物种的覆盖率的同时，考虑生态完整性和社会经济活动，战略性地扩大保护区。结果表明，77.9%的流域发生了显著的栖息地退化。目前保护区覆盖6.3%的网站，代表8.7%的关键物种的总分布。关于30%的保护阈值，在生态完整性优先情景和迭代所涉及的社会经济成本情景下，保护额外的27.2%的场地将分别覆盖关键物种范围的93.5%和80.4%。我们的研究结果可以用来通知即将采取的行动与喀斯特地区保护相关的政策。
SummaryThere have been calls for the expansion of protected areas (PAs) to tackle the ongoing biodiversity loss, yet it is unclear where future PAs might help to protect biodiversity in degraded landscapes under the conservation planning principles of complementarity, connectivity and cost-effectiveness. Our conservation goal is to increase the PA network coverage to up to 30% of the landscape of the Zhangjiang River Basin for target species in the karst area of southwest China, a global biodiversity hotspot. Zonation 4GUI was used to evaluate the adequacy of current PAs and to strategically expand PAs while maximizing the coverage of target species and considering ecological integrity and socioeconomic activities. The results show that significant habitat degradation has occurred across 77.9% of the basin. The current PAs cover 6.3% of the site and represent 8.7% of the total distribution of key species. With regards to the threshold of protection of 30% of the area, protecting an additional 27.2% of the site under an ecological integrity prioritization scenario and a scenario of the socioeconomic costs involved in iteration would cover 93.5% and 80.4% of the ranges of the key species, respectively. Our results can be used to inform the upcoming actions associated with karst area conservation-related policies.
