河池金城江区野生重点药用植物资源调查与评价

Investigation and Evaluation of Wild Key Medicinal Plant Resources in Jinchengjiang District of Hechi

目的:基于全国第4次中药资源普查工作,对河池金城江区野生重点药用植物资源进行调查,以期探明金城江区野生重点药用植物资源现状,为该区域药用植物的保护和合理开发提供决策参考。方法:采取野外样线和样方调查相结合的方法,对金城江区境内野生重点药用植物资源开展调查,整理该区野生重点药用植物的种类、分布、功效、出现频率、蕴藏量等数据并进行综合分析。结果:金城江区有野生重点药用植物43种,隶属31科43属,总蕴藏量14070.82 t,包括国家Ⅱ级野生保护植物1种、广西道地药材8种;对重点药用植物的性状、功效、分布和蕴藏量等特点进行分析评价,提出该区域应被列为珍稀保护药用植物的物种。结论:金城江区野生重点药用植物资源较丰富,岩溶特色明显,但是部分药用植物分布区域狭窄、出现频率低、蕴藏量小,野生资源处于稀缺状态,对部分特色药用植物的保护刻不容缓。

Objective:To investigate the wild key medicinal plant resources in Jinchengjiang district of Hechi based on the fourth national survey of traditional Chinese medicine resources,in order to find out the current situation of wild key medicinal plant resources in Jinchengjiang district,and to provide decision-making reference for the protection and rational development of medicinal plants in this region.Methods:The method of combining field sample line and sample survey was adopted to investigate the resources of key wild medicinal plants in Jinchengjiang district.The data of species,distribution,efficacy,occurrence frequency and reserves of key wild medicinal plants in this area were collected and comprehensively analyzed.Results:There were 43 species of wild key medicinal plants in Jinchengjiang district,belonging to 31 families and 43 genera,with a total stock of 14070.82 t,including 1 national levelⅡwild protected plant and 8 kinds of Guangxi local medicinal materials;The characters,efficacy,distribution and reserves of the key medicinal plants were analyzed and evaluated,and it was suggested that this region should be listed as the rare and protected medicinal plant species.Conclusion:The wild key medicinal plants in Jinchengjiang district are rich in resources and have obvious karst characteristics.However,the distribution of some medicinal plants is narrow,the frequency of occurrence is low and the reserves are small,wild resources are in a scarce state.It is imperative to protect some of the featured medicinal plants.
