이 연구는 식생기반재돌망태기슭막이의 녹화효과를 분석하였다. 식생기반재돌망태기슭막이 시공 후 20일 경과 후 식생이 발아하기 시작하였으며, 봄의 피복율은 약 20%를 나타내었다. 여름에는 피복율이 약 65%로 나타났으며, 출현종은 파종한 목본인 낭아초, 참싸리 모두 출현 하였으며, 초본으로는 벌노랑이, 자운영, 수레국화, 기생초, 코스모스 등 5종이 출현하였다. 이때 침입식생은 개망초, 새, 벼룩자리, 버들잎엉겅퀴, 미국자리공, 망초, 미국가막사리, 민들 레, 아까시나무, 찔레, 물쑥, 매듭풀, 자귀나무, 바랭이, 쇠무릅 등 15종이었다. 가을에는 피 복율이 약 82%로 나타났으며, 출현종은 6종, 침임식생은 5종으로 나타났다. 또한 식생기반재 돌망태기슭막이와 전석기슭막이, 식생낭기슭막이를 비교한 결과, 식생기반재돌망태기슭막이만 녹화효과가 나타났다.
This study was analyzed revegetation effect of gabion systems with vegetation base materials revetment. After construction of the gabion systems with vegetation base materials revetment the seed germination was started in 20 days later. Also, in the spring and summer season, the surface coverage rate of gabion systems with vegetation base materials revetment was appeared about 20% and 65%, respectively. Among the investigated plants, sowed woody plant(Lespedeza cyrtobotrya Miq. and Indigofera pseudotinctoria Matsum.) was occurred about 100%. In addition, five species herb plant(Lotus corniculatus var. japonica Regel, Astragalus sinensis L., Centaurea cyanus, Coreopsis tinctoria Nutt. and Cosmos bipinnatus Cav) appeared. At this time, the 15 invasive vegetation species were Erigeron annuus PERS., Arundinella hirta, Arenaria serpyllifolia L., Cirsium lineare(Thunb.) Sch. Bip, Phytolacca americana, Erigeron canadensis, Bidens frondosa L., Taraxacum platycarpum Dahlst., Robinia pseudoacacia L., Rosa multiflora var. multiflor Thunb., Artemisia selengensis Turcz. ex Besser, Kummerowia striata (THUNB.) SCHINDL., Albizia julibrissin Durazz., Digitaria sanguinalis (L.) Scop and Achyranthes japonica (Miq.) Nakai. In the fall season, the surface coverage rate of gabion systems with vegetation base materials revetment was appeared about 82%. And appeared species and invasive vegetation species were six and five species, respectively. Consequently, compared to the gabion systems with vegetation base materials revetment, Streanm stone revetment and vegetation bag revetment were results demonstrated revegetation effect only the gabion systems with vegetation base materials revetment.
