Hyangju Lee,Changjun Kim,Wonhyeon Lim J-INSTITUTE 2022 International Journal of Crisis & Safety Vol.7 No.2

Purpose: By analyzing 1,441 flora survey data of the 3rd to 5th data of the National Natural Environ-ment Survey, the differences by region and altitude were analyzed in the species number of vascular plants and naturalized plants distributed throughout Korea, and the naturalization index. This study aimed to reveal the correlation by altitude in the species number of vascular plants, the species number of naturalized plants, and the naturalization index. Method: This study utilized the flora survey data for 14 years from 2006 to 2019 in the 3rd to 5th National Natural Environment Survey. One-way ANOVA analysis was performed by region and altitude to examine the differences in the species number of vascular plants, the species number of naturalized plants, and the naturalization index. Researchers performed curvilinear estimation regression analysis to find the correlation, and SPSS Statistics 21 statistical program was used for statistical analysis. Results: There were differences by region and altitude in the species number of vascular plants, the species number of naturalized plants, and the naturalization index. The species number of vascular plants had a positive correlation with an increase in the number of species as the altitude increased. The species number of naturalized plants had a negative correlation with a decrease in the number of species as the altitude increased. The naturalization index had a negative correlation that decreased up to a certain altitude, increased after that point, and then decreased again. Conclusion: As for vascular plants, the higher the altitude, the greater the species number of vascular plants, and the lower the altitude, the fewer vascular plant species. Conversely, as for naturalized plants, the lower the altitude, the greater the species number of naturalized plants, and the higher the altitude, the fewer naturalized plant species. In addition, as for the naturalization index, the lower the altitude, the higher the naturalization index, and the higher the altitude, the lower the naturalization index. This study is expected to be utilized as basic data for managing naturalized plants.

본 연구는 창원시 정병산에 분포하는 관속식물상을 종합적으로 분석하여 식물자원의 보전 및 관리방안을 수립하기 위한 기초자료를 제공할 목적으로 수행되었다. 현장조사는 2014년 2월부터 2020년 11월까지 9개 코스에서 평균 30회 이상 이루어졌으며, 그 결과를 정리한 것이다. 정병산의 관속식물상은 107과 275속 404종 5아종 10품종 45변종 등 총 464분류군이 확인되었다. 이 중 용추계곡 주변에서 확인된 관속식물상은 총 319분류군으로 전체의 약 69%를 차지하였다. 특산식물은 자란초, 처진물봉선, 광릉골무꽃, 은꿩의다리 등 14분류군이 확인되었고, 특산율은 3%, 우리나라 특산식물의 약 4%에 해당하였다. 희귀식물은 멸종위기종인 처진물봉선, 목련, 왕벗나무(식) 등 3분류군, 위기종은 깽깽이풀, 백양꽃 2분류군, 취약종은 금붓꽃 1분류군, 약관심종은 쥐방울덩굴, 광릉골무꽃, 이팝나무, 덩굴꽃마리, 말나리, 뻐꾹나리 등 6분류군, 자료부족종은 옥녀꽃대 1분류군 등 총 13분류군이 확인되었다. 이중 뻐꾹나리와 금붓꽃을 제외한 11분류군은 자생지가 계곡 주변에서 확인되었다. 이들 희귀식물 분류군에 대해서는 자생지의 생태적 특성을 밝히려는 연구가 이루어져야 할 것이다. 귀화식물은 미국까마중, 미국쑥부쟁이, 유럽점나도나물 등 19분류군이 확인되었으며, 귀화율은 4.1%였다. 산림으로의 심각한 침입이 우려되는 4등급에 해당하는 종은 달맞이꽃, 미국쑥부쟁이, 개망초 3분류군이었으며, 생태계교란야생식물은 돼지풀과 미국쑥부쟁이 그리고 자생잡초인 환삼덩굴 3분류군이었다. 귀화식물 19분류군 중 11분류군이 용추계곡 주변에서 확인되었는데, 향후 지속적인 탐방객 증가와 간헐적인 공사로 생육환경의 교란이 발생할 가능성이 높아 계곡부 주변으로의 귀화식물 유입에 대한 모니터링이 이루어져야 할 것이다. 식물구계학적 특정식물은 Ⅰ등급으로 금붓꽃, 자란초 등 37분류군, Ⅱ등급이 층꽃나무, 노랑제비꽃 등 3분류군, Ⅲ등급이 연복초 등 12분류군, Ⅳ등급이 가는범꼬리, 산복사나무 등 4분류군, Ⅴ등급이 깽깽이풀, 백양꽃 등 5분류군으로 총 61분류군이 확인되었다. 기후변화 적응 대상식물은 13분류군이 확인되었는데, 특산식물로 해변싸리, 처진물봉선 등 4분류군, 북방계식물로 조선현호색 1분류군, 남방계식물로 옥녀꽃대, 둥근배암차즈기 등 8분류군이 나타났다. This study was conducted for the purpose of providing basic data for establishing a plant resource conservation and management plan by comprehensively analyzing the vascular flora distributed in Jeongbyeong(Mt.), Changwon-city. Field surveys were conducted on average more than 30 times in 9 courses from February 2014 to November 2020, and the results are summarized as follows. The vascular flora of Jeongbyeongsan(Mt.) was summarized as 464 taxa including 107 families, 275 genera, 404 species, 5 subspecies, 10 forms and 45 varieties. Among them vascular flora identified around Yongchu valley was 319 taxa, accounting for about 69% of the total. The endemic plants were 14 taxa such as Impatiens koreana, Thalictrum actaefolium var. brevistylum and so forth,, and endemic plants rate was 3.01% and 3.89% of 360 taxa of Korean endemic plants.

Among these rare plants, 11 taxa except for Tricyrtis macropoda and Iris minutoaurea were found in the vicinity of the Yongchu valley. For these rare plants, research to elucidate the ecological characteristics of their habitats should be conducted. The naturalized plants were 19 taxa including Solanum americanum, Aster pilosus and so forth, and the naturalized index was 4.1%. Invasive alien plants were Ambrosia artemisiifolia and Aster pilosus. The plants of concern for serious invasion into forests were 4 taxa such as Oenothera biennis, Aster pilosus and Erigeron annuus. Of the 19 taxa of naturalized plants, 11 taxa were identified around the Yongchu valley. Since there is a high possibility that the growing environment will be disturbed due to the continuous increase in visitors and intermittent construction, the spread of naturalized plants around the valley area should be monitored. The specific plants by floristic region were 61 taxa; 37 taxa such as Betula schmidtii and Aconitum jaluense of grade I, 3 taxa such as Caryopteris incana and Lilium distichum of grade II, 12 taxa such as Acer palmatum and Adoxa moschatellina of grade III, 4 taxa such as Fallopia sachalinensis and Prunus davidiana of grade IV, 5 taxa such as Impatiens koreana and Jeffersonia dubia of grade V, Target plants adaptable to climate change were 13 taxa; 4 taxa of endemic plants, 1 taxa of northern plant, and 8 taxa of southern plants.
