This study was carried out to investigate vegetation structure and soil property of natural habitat of Polygonatum stenophyllum to provide basic information for propagation, conservation and restoration. Habitats of Polygonatum stenophyllum were classified into Hemiptelea davidii-Robinia pseudo-acacia dominant population (Yeongwol-eup), Pinus densiflora-Hemiptelea davidii-Callicarpa japonica dominant population (Nam-myeon), and Hemiptelea davidii-Rubus crataegifolius dominant population (Gangchon-ri). The soil pH 6.49~7.28; and electron conductivity 0.10~0.19 ds/m. The average content of organic matter, total nitrogen, available P2O5, Ca2+, Mg2+, K+, and Na+ were 8.24~16.45 g/kg, 0.02~0.13%, 45.67~123.67 mg/kg, 4.61~6.71 cmol(+)/kg, 0.17~0.63 cmol(+)/kg, 0.06~0.27 cmol(+)/kg and 0.03~0.30 cmol(+)/kg, respectively. Species diversity index (H'), maximum species diversity index (H' max), evenness (J') and dominance (1-J') of investigated sites ranged 1.0323 (Nam-myeon)~1.1134 (Yeongwol -eup), 1.4914 (Gangchon-ri)~1.6128 (Nam-myeon), 0.6401 (Nam-myeon)~0.7270 (Yeongwol-eup) and 0.2730 (Yeongwol-eup)~0.3599 (Nam-myeon) respectively.
