摘　　要：【目的】调查广西蔓性千斤拔的野生资源地理分布特点、生长特性和种群特征,为广西蔓性千斤拔的种质资源保存和良种选育提供依据。【方法】采用文献检索与样本调查的方法对广西蔓性千斤拔的植物学特征、生物学特征进行汇总整理;采用实地调查和走访调查相结合的方法对广西蔓性千斤拔的野生资源的分布及生态环境、群落特征、生长特性等进行调查。【结果】野生蔓性千斤拔群落特征与生长的地形地貌有一定的相关性,通常生于河边、田埂、丘陵地区,适应性强,对温度、土壤及光照的适应范围较宽;野生蔓性千斤拔在不同的生长环境中其生长特性存在较大的差异;人工栽培蔓性千斤拔各产量构成因素指标均远高于野生。【结论】系统探清了广西蔓性千斤拔的野生资源地理分布特点、生长特性和种群特征,为蔓性千斤拔的种质资源保存和良种选育提供依据。广西蔓性千斤拔野生资源濒于枯竭,亟待保护。Objective To provide the basis for germplasm preservation and breeding, we investigated the geographical distribution of resources of wild Moghania philippinensis（Merr. et Rolfe）Li. in Guangxi province as well as its growth characteristics and population characteristics. Methods Literature retrieval and sampling survey were used for the investigation of the botanical and biological characteristics of Moghania philippinensis in Guangxi province. Field survey combined with visit methods were used to investigate resource distribution, growth habitats,population features,and growth characteristics of wild Moghania philippinensis. Results The population features of wild type of Guangxi Moghania philippinensis are correlated with their growth habitats. Guangxi Moghania philippinensis grows well beside rivers, on the field ridges and in the hilly areas, and has a good adaptive ability to the temperature, soil and illumination. The population features of wild type of Guangxi Moghania philippinensis vary greatly in different growth habitats. Cultivated Moghania philippinensis has higher output indexes than the wild. Conclusion The geographical distribution of resources of wild Moghania philippinensis（Merr. et Rolfe）Li. in Guangxi province as well as its growth characteristics and population characteristics has been figured out, which will supply evidence for the germplasm preservation and breeding of Moghania philippinensi. The resources of wild Moghania philippinensis（Merr. et Rolfe）Li. are now close to being exhausted,and urgent protection will be needed.
