摘　　要：猴腿蹄盖蕨〔Athyrium multidentatum(Dol.)Ch ing〕是一种食药兼用型植物,为了合理的开发利用,在吉林省东南部山区临江市境内,调查分析了其分布的5个典型群落,并测量株高、冠幅、密度和含水率。结果表明:猴腿蹄盖蕨的生态适宜性较广,不同群落条件下株高、冠幅、密度差异较大,水分和光照强度是影响其生长发育和繁殖的主要生态因子,适当的强光照和高湿度条件有利于猴腿蹄盖蕨的有性繁殖和生长发育,针阔混交林林缘和白桦次生林林窗群落条件最适宜猴腿蹄盖蕨种群的发展。环境条件的差异对含水率的影响较小。通过探讨适合种群生长发育的环境条件,为引种驯化提供科学依据。Athyrium multidentatum （oDol.） Ching is a plant which can be used as food and medical herb. In order to rationally develop and utilize this wild plant resource, five typical plots for this study were obtained in Linjiang, on the mountain areas of southeast Jilin Province. Plant high, crown breadth, density and water content of Athyrium multidentatum （ Dol. ） Ching were measured in five typical plots. The results show that Athyrium multidentatum （ Dol. ） Ching can grow in widely conditions about air temperature, humidity, light illumination and soil water content. There are great differences about plant high, crown breadth, density in five typical plots. Water and light illumination are dominant ecological factors to influence growing development and reproduction. It will be favorable conditions with suitable strong light illumination and high moisture for growing development and reproduce. It is the most suitable environmental conditions in mixed broadleaf - conifer forest edge and the gap of secondary birch forest communities for Athyrium multidentatum （ Dol. ） Ching to grow. The differences from environmental conditions have lesser influence to water content of Athyrium multidentatum （Dol.） Ching. The results can provide scientific basis for cultivating condition of Athyrium multidentatum （Dol.） Ching.
