为了更好地利用和保护野生枇杷（Eriobotrya japonica Lindl．）资源，我们对普通枇杷11个野生居群的典型生境及群口尺度、年龄结构及濒危程度等进行了调查及分析。调查结果表明：在我国的湖北、四川、贵州、广东4省的部分山区还残存若干普通枇杷野生居群；其中湖北五峰及建始居群、四川石棉居群、贵州湄潭居群有较大的资源保有量，生境没有受到破坏，居群树龄结构合理，但是湖北通山及巴东居群、广东乳源及阳山居群的群口数量则相对较少，居群树龄结构不合理。分析后我们认为：人类活动是导致普通枇杷野生资源濒危的主要因素，物种之间的生存竞争也危及到野生枇杷的生存。

In order to protect and further utilized of the wild loquat resources, studies were carried out on 11 wild lo-quat populations in China, including investigate the typical habitats, demographical size, age structure and endan-gered situation. The results showed that wild loquat populations could be found in some mountain areas of Hubei prov- ince, Sichuan province, Guizhou province and Guangdong province; Among the investigated populations, those in Wufeng and Jianshi county of Hubei province, Shimian county in Sichuan province and Meitan countyGuizhou prov-ince have larger demographical size with healthy age structure. However, the populations of Tongshan and Badong county in Hubei province, as well as those in Ruyuan and Yangshan county of Guangdong province, were with com-paratively smaller demographical size and unhealthyage structure. The studies suggested that the wild loquat resources become endangered mainly resulted from human activities; besides the survival competition among species could also jeopardize the wild loquat populations.
