摘　　要：目的:明确宁夏野生银柴胡资源分布现状及群落结构特点,为银柴胡野生资源保护以及该物种野生抚育方法的研究提供参考。方法:采用样地调查法对野生银柴胡分布点进行实地踏勘,统计不同微地形生境条件下银柴胡的分布数量并估算其蕴藏量,同步分析不同群落的种群组成和结构特征。结果:宁夏野生药用银柴胡资源分布较广,覆盖宁夏10个行政辖区市县,主要分布于灵武市和大武口区;总蕴藏量为202 356.5 kg,是宁夏第三次中药资源普查时银柴胡蕴藏量的7.1倍。野生银柴胡群落生境多为荒漠低凹处的沙质地,分布多呈群聚连片的特点。常见的建群种或优势种主要有柠条锦鸡儿、黑沙蒿、草木樨状黄芪和刺沙蓬等植物。结论:该研究总结和归纳了野生银柴胡资源蕴藏量及其分布地的微环境特征,对于后续银柴胡野生资源的保护以及当地特色药材开发利用的策略制定具有指导意义。Objective:To clarify the distribution status and community structure of wild Stellaria dichotoma var.lanceolata re-sources in Ningxia,so as to provide reference for the conservation of wild Stellaria dichotoma var.lanceolata resources and the study of wild tending methods of this species.Methods:The distribution sites of wild Stellaria dichotoma var.lanceolata were investigated with the method of plot survey.The distribution quantity and reserves of Stellaria dichotoma var.lanceolata under different microtopographic habitat conditions were calculated,and the population composition and structure characteristics of different communities were analyzed simultaneously.Results:The wild medicinal resources of Stellaria dichotoma var.lanceolata were widely distributed in Ningxia,covering 10 cities and counties in Ningxia,mainly in Lingwu city and Dawukou district.The total reserve was 202356.5 kg,which was 7.1 times of Stellaria dichotoma var.lanceolata in the third survey of Chinese medicine resources in Ningxia.The habitat of wild Stellaria dichoto-ma var.lanceolata was mostly sandy land in desert low depression,and the distribution was mostly clustered and contiguous.The com-mon or dominant species were Caragana korshinskii,Artemisia ordosica,Astragalus melilotoides,Salsola tragus and others.Conclusion:This study summarizes and concludes the reserves of wild Stellaria dichotoma var.lanceolata resources and the microenvironment char-acteristics in their distribution areas,which is of great significance for the subsequent protection of wild Stellaria dichotoma var.Lanceo-lata resources and the development and utilization strategy formulation of local characteristic materials.
