Abstract

Securing sufficient planting strip for street shrubs has a limitation. So many different shrubs which have been planted in the streets looks consider its visual aspect rather than growth characteristics. In this study, we compared with the growth condition of planted shrubs and construction condition of its planting strip. $Photinia$ $glabra$, $Euonymus$ $japonicus$, $Camelia$ $sasanqua$, $Nandina$ $domestica$, $Abelia$ $grandiflora$ were selected in the Busan City, Korea. The planting strips width were 0.5~0.9m which is not relatively different by each species. Species which have narrow growth character of root hair in the natural bed ($Nandina$ $domestica$, $Abelia$ $grandiflora$) have a good growth condition in the street planting strip, oppositely shrubs which have wide growth character of root hair ($Photinia$ $glabra$, $Euonymus$ $japonicus$, $Camelia$ $sasanqua$) have a relatively bad growth condition. Hereupon, there have a necessity which should be select the different shrub species for the planting strip of the street.

도심내 가로에 조성하는 녹지대는 폭 확보에 한계가 있다. 현재 가로녹지대 관목림 조성을 위한 수종은 녹지대 환경의 고려보다는 경관적 측면에서 여러 수종이 다양하게 식재되고 있는 상태이다. 본 연구에서는 부산시 가로녹지를 대상으로 $Photinia$ $glabra$ (홍가시나무), $Euonymus$ $japonicus$ (사철나무), $Camelia$ $sasanqua$ (애기동백), $Nandina$ $domestica$ (남천), $Abelia$ $grandiflora$ (꽃댕강나무) 5종의 생육상태와 녹지대 조성 특성을 비교하였다. 가로녹지대는 폭 0.5~0.9m로 수종별로 차이는 없었다. 수목의 생육특성 분석결과, 자연지역에서 세근의 발달 폭이 현재 조성된 녹지대 폭보다 좁은 남천과 꽃댕강나무는 생육이 양호하였다. 반면 세근이 폭 2m이상 넓게 발달하는 수종인 홍가시나무, 사철나무, 애기동백은 폭이 좁은 가로녹지대에서는 생육상태가 상대적으로 좋지 않았다. 이에 가로녹지대 조성시 확보할 수 있는 녹지대 폭에 따라 식재하는 수종을 달리할 필요성이 있었다.
