陕西秦岭悬钩子属植物资源分析及县域分布
Species resource and distribution of genus Rubus in Qinling Mountains within Shaanxi
目的 明确陕西秦岭悬钩子属植物资源县域分布格局,确定热点地区,绘制以行政单位为基础的专题图,总结和分析陕西秦岭悬钩子属植物生长状况及分布情况。 方法 野外调查法与文献资料的整理对比,确定悬钩子属植物的种类、生境、观赏特性和空间分布;以行政县(区)为单位,按照自然间断点分级法,绘制县域水平分布图;使用Dobson筛除算法筛选其植物分布热点县(包括县级市和区)。 结果 陕西秦岭悬钩子属植物共计36种10变种。广泛分布于海拔500~2 999 m,最宜海拔1 500~1 999 m。分布热点区域为8个县(区),南坡以宁陕、石泉为核心,北坡以太白为核心。分化强度与物种密度呈高相关,分布趋势为沿海拔较高的山区向海拔较低的山区逐渐递减;数量在研究区中部地区两侧方向上呈现阶梯形减少的趋势。 结论 1)陕西秦岭悬钩子属植物种类繁多,生活型多样,花色、果色丰富,主要观赏季节为夏季。2) 物种分化强度一定程度上影响物种多样性分布格局,陕西秦岭悬钩子属植物空间区域格局与山脉海拔高度密切相关。3) 陕西秦岭地区气候和地形条件共同影响悬钩子属植物的县域分布格局和分化强度。。
Objective The study aimed to clarify the distribution pattern of the genus Rubus plants in different counties of the Qinling Mountain area of Shaanxi,identify hotspot areas, draw thematic maps based on administrative units, and to summarize and analyze their growth status and distribution in the Qinling Mountains. Method Combined with literature data, the method of field survey was used to determine the species, habitat, ornamental characteristics and spatial distribution of the genus plants.With the administrative counties (districts) as the units, the county-level distribution (including county-level cities and districts) of the plants was mapped according to the method of natural intermittent point classification, followed by screening the hotspot counties of the genus plant distribution with the method of Dobson. Result Rubus plant are 36 species and 10 Rubus variants in Qinling,Shaanxi Province.It is widely distributed at the altitude of 500~2 999 m,and the most suitable altitude is 1 500~1 999 m.The distributed hot spots are 8 counties (districts),with the south slope taking Ningshan and Shiquan as the core, and the north slope taking Taibai as the core.The intensity of differentiation is highly correlated with the species density, and the trend decreases from the higher mountains to the lower mountains; the number decreases in both sides of the region. Conclusion The Qinling Mountains in Shaanxi Province have a wide variety of Rubus,with rich colors and fruit colors.The main ornamental season is summer.The intensity of species differentiation affects the distribution pattern of species diversity to some extent, and the spatial regional pattern of Rubus plant in Qinling Mountains,Shaanxi Province is closely related to the altitude of mountains.The climate and topographic conditions in Qinling Mountains of Shaanxi Province influence the county distribution pattern and differentiation strength of Rubus plant.
