본 조사는 우리나라의 조경공사에 있어 조경수목의 사용실태를 조사분석하여 이의 생산 및 유동의 개성에 필요한 기초정보를 얻고저 수행하였다. 1983년 및 1984년의 2개년간 11개종합조경업체에 수주된 328개 조경공사에 사용된 조경수목의 사용실태를 조사분석하였던 바 그 결과를 요약하면 다음과 같다. 1) 교목과 관목수종은 식재비율은 1:6이었고 상녹과 낙엽수종의 식재비율은 1:4였으며 사용빈도가 가장 높은 수종은 화양목, 향나무, 느티나무, 은단풍이었고 사용량이 가장많은 수종은 쥐똥나무, 개나미, 회양목, 산철쭉이었다. 2) 관목의 경우 쥐똥나무 개나미 및 회양목 3개수종의 사용량이 전체관목사용량의 $\frac{1}{2}$을 크게 상회하는 심한 편중도를 나타내었으나 교목에 있어서는 잣나무를 위시한 8개수종의 사용량이 전체교목사용량의 $\frac{1}{2}$를 점하였다. 3) 비고시수종에 비해 고시수종의 수는 $\frac{1}{4}$에 불과하였어나 고시수종의 사용한도는 비고시수종의 6배이며 고시품목의 사용량은 전체의 82.5%를 점하였고 고시품목사용율은 교목보다는 관목 그리고 낙엽보다는 상록수종에서 현저히 높았다. 4) 비고시규격품보다는 고시규격품의 사용량이 현저히 많았고 동일수고일 때 수관건 혹은 근원직경 또는 흉고식경이 큰 규격이 현저히 선호되는 경략이었는데 우리나라 규격은 일본규격에 비해 수고에 대한 수관건 혹은 근원직경 또는 흉고직경비율이 현저히 높았다.

This study was conducted to investigate the planting status of the woody landscape plant species and to obtain some fundamental informations for improvement of production and sales circulation of the woody landscape plants. The details of 328 landscape projects which were carried out for 2 years from 1983 to 1984 were surveyed to investigate the utilization status of the woody landscpe plants. The results obtained are summarized as fellows ; 1) The utilization rate of the trees to the shrubs as woody landscape plants was 1 : 6 and that of the evergreens to deciduous plants was 1 : 4. The plant species which were most frequently used in landscaping were Buxus microphylla koreana, Juniperus chinensis, Zelkova serrata and Acer saccharinum, howevr, plants which were used in largest quantitites were Ligustrum obtusifolium, Forsythia koreana, Buxus microphylla koreans and Rhododendron yedoense var. poukhanense. 2) The number of plants planted among 3 shrub species(Ligustrum obtusifolium, Forsythia koreana and Buxus microphylla korana) exceeded half of the total number of shrubs planted for landscping, however, the number of plants planted among 8 tree species including Pinus koreainensis were about half of the total tree species. 3) The number of government price specified plant species was only 20%, but the utilization frequency of the price specified plants was as much as 6 times than unspecified plants and 85% of plants used in landscaping works were the price specified plants. The utilization rate of the price specified plants was significantly high in the shrubs than the trees and in the evergreen than deciduous plants. 4) The amounts in use of the price specified standardized plants were significantly more than those of unstandardized plants. When the plant heights are same, the plants having wider canopy or stem diameter were rather frequently used in the landscaping works. The ratio of the width of the canopy or stem diameter to the stem length of the plants in the Korean standard is significantly greater than that in the Japanese standard.
