한반도 개모시풀의 자생지 환경조건에 따른 분포특성, 토양성분, 혼생식물을 조사한 결과는 다음과 같다. 개모시풀의 상대밀도와 상대피도는 7.0%와 25.6%이었다. 해발고도별로는 200 m 이하에서 가장 많이 분포하였으며 해발고도가 높아질수록 분포지역이 적었다. 경사도별로는 20˚ 이하에서 80% 이상이 자생하였고, 사면별로는 남사면보다 햇빛이 적은 서사면과 북사면에서 집중되었다. 광량에 따른 분포는 90% 정도가 중광이나 약광이었고, 습윤 정도에 따른 분포는 69.1%가 습윤지역이었다. 자생지의 토성은 식양토이었으며, 평균 pH는 6.2로서 약산성 토양이었다. 유기물 함량은 24 g kg?1이었으며, 유효인산은 31 mg kg?1이었다. 혼생하는 식물은 60과 125속에 총 171분류군이었으며, 상대밀도와 상대피도가 가장 높은 혼생식물은 사위질빵이었다.
This study was conducted to evaluate geographical distribution patterns of natural habitats, soil properties, and plant species grown with native Boehmeria platanifolia in South Korea. The relative density and coverage of Boehmeria platanifolia were 7.0% and 25.6% respectively. Most Boehmeria platanifolia were growing below 200 m of altitude, and they were rarely found at the higher altitude. Over 80% of Boehmeria platanifolia's habitats were found at below 20˚ and their habitats were concentrated at the west and the north face slope rather than the south face slope. Nearly 90% of Boehmeria platanifolia were grown at little and middle light condition's area, and 69.1% of them were natively growing in humid soil in their natural habitats. Soil texture of their habitats were mostly clay loam and the soil pH was 6.2. The contents of soil organic matter was 24 g kg?1 and P2O5 was 31 mg kg?1. Plant species grown with native Boehmeria platanifolia were 60 family, 125 genus and 171 species. Clematis apiifolia showed the highest relative density and coverage among plant species grown with native Boehmeria platanifolia.
