摘要

空间保护工具通常侧重于识别具有感兴趣物种群的区域。因此,有必要确定影响物种(热点)集中的主要因素及其位置。我们的问题是:现有的严格保护区是否有效地覆盖了主要的区域生物多样性热点;热点排列有哪些特点?要覆盖主要的生物多样性,距离生物多样性研究中心的最小距离是多少?本文分析了影响摩尔多瓦共和国(欧洲俄罗斯)164种濒危植物空间分布的因素。为了量化物种分布,我们使用了100平方公里样方的网格制图方法。在研究区内确定了4个濒危物种生物多样性研究中心(BDRC),包括2个保护区、萨兰斯克镇和1个区域重点保护区。约50%的物种和种位集中在以保护区为中心的24km半径范围内。从研究结果来看,保护区的缓冲带宽度应为5 ~ 10 km,新建保护区应先确定区域生物多样性热点区域。此外,还应检验一个地区植物物种丰富度对保护区布置的正确性。

The Arrangement of Threatened Plants in Mordovia: The Role of Biodiversity Research Centers
ABSTRACT Spatial conservation tools usually focus on identifying areas having species groups of interest. Consequently, there is a need to identify the main factors influencing the concentration of species (hotspots) and their locations. We asked: whether existing strictly protected areas are efficient to cover the main regional biodiversity hotspots; what characteristics are associated with hotspot arrangement; what is the minimal distance from a biodiversity research center needed to cover the main biodiversity amount. We analyzed factors influencing the spatial arrangement of 164 threatened plant species in the Republic of Mordovia (European Russia). To quantify species distribution, we used a grid mapping approach using 100 km2 quadrats. We identified four biodiversity research centers (BDRC) of threatened plant species in the study area, including two protected areas, the town of Saransk, and a regional key conservation area. About 50% of species and species locations were concentrated within a 24-km radius around BDRCs. From our results, buffer zones of protected areas should have a 5–10 km width and the establishment of new protected areas should be preceded by the identification of regional biodiversity hotspots. Additionally, the correctness of protected area arrangement with plant species richness in a region should be tested.
