본 연구의 목적은 경주시 어린이공원의 조경식물과 침입외래식물을 조사 및 분석하여 도시공원에서 조경식물의 식재설계와 관리에 필요한 기초 자료를 제공하기 위함이다. 연구결과를 요약하면 다음과 같다. 연구대상지는 경주시 어린이공원 44개소이며, 연구기간은 2021년부터 2022년까지이다. 전체 어린이공원에 식재된 조경식물은 47과 83속 96종 7변종 5품종 5잡종 7재배변종의 120분류군이었다. 분류군수가 가장 많은 공원은 양정어린이공원과 불국소공원이고, 가장 적은 공원은 대신어린이공원, 나무어린이공원, 토용어린이공원, 용강고분이었다. 가장 많이 식재된 조경식물은 느티나무였다. 성상별 분석 결과, 상록침엽교목 14분류군, 상록침엽관목 1분류군, 상록활엽교목 1분류군, 상록활엽소교목 3분류군, 상록활엽관목 9분류군, 낙엽침엽교목 2분류군, 낙엽활엽교목 29분류군, 낙엽활엽소교목 11분류군, 낙엽활엽관목 19분류군, 초본 31분류군이었다. 자생성 분석 결과, 국내 원산 96분류군, 외국 원산 24분류군이었다. 침입외래식물은 21과 52속 70종 1잡종의 71분류군이며, 생태계교란 생물은 애기수영, 도깨비가지, 돼지풀, 미국쑥부쟁이, 환삼덩굴 5분류군으로 나타났다.
Abstract
The purpose of this study was to investigate and analyze the landscape plants and invasive alien plants in children’s parks in Gyeongju City and to provide basic data necessary for the planting design and management of landscape plants in urban parks. The results are summarized as follows. The research sites are 44 children’s parks in Gyeongju City, and the research period is from 2021 to 2022. The total numbers of planted landscape plants in children’s parks were 120 taxa including 47 families, 83 genera, 96 species, 7 varieties, 5 forms, 5 hybrids and 7 cultivar. The parks with the largest number of classified groups were Yangjeong Children’s Park and Bulgukso Park, while the parks with the smallest number were Daeshin Children’s Park, Namu Children’s Park, Toyong Children’s Park, and Yonggang Tomb. The most commonly planted landscape plant was the zelkova serrata. The results of forms were 14 taxa of evergreen coniferous trees, each 1 taxon of evergreen coniferous shrubs․evergreen broad leaved trees, 3 taxa of evergreen broad leaved small trees, 9 taxa of evergreen broad leaved shrubs, 2 taxa of deciduous coniferous trees, 29 taxa of deciduous broad leaved trees, 11 taxa of deciduous broad leaved small trees, 19 taxa of deciduous broad leaved shrubs, and 31 taxa of herbs. As a result of the nativeness analysis, there were 96 taxa of domestic origin and 24 taxa of foreign origin. The numbers of invasive alien plants were 71 taxa including 21 families, 52 genera, 70 species and 1 hybrid. The ecosystem disturbing species were 5 taxa including Rumex acetosella, Solanum carolinense, Ambrosia artemisiifolia, Symphyotrichum pilosum, and Humulus scandens.
