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.

노재현 한국조경학회 1998 韓國造景學會誌 Vol.26 No.3

The purpose of this study is on identifying real condition of naturalized plants in urban green space. For this, Chollabak-do region was selected for case study. The occurring frequency and distribution status was investigated by field survey. The area of green open space, level of management and passed years after construction etc, were analized to identify the influence on occurrence of naturalized plants. The result is as follows: 1. In 18 sites, 145 taxa as weed species including naturalized plants were occurred. Average No. of occurring taxa is 22.7. Two families of plants, Graminae and compositae charged the most part. Also the rate of naturalized plant among them is 29.7%. 2. Naturalized species showing high occurring rate are 14 taxa of compositae, 5 taxa of Gramineae, Leguminosae and 4 taxa of cruciferae. These plants of previous four somatic polymorphism among all the naturalized plants. 3. The taxa number of naturalized plants were reducedby intensive management. But the rate of naturalized plants in extensively managed area was relatively lower than intensively managed one. Naturalizd plants were widely distributed in most of urban green space with being cognitioned as whole weed. 4. In origin of naturalized plants, the taxa from north America were 16 and the taxa from Europe were 16. Therefore the rate originated from north America and Europe charged high part as 68.2%. The rate of Annual, Biennial and Perennial were each 78.7%, 21.3%. The alternative of management for control aganist disturbance by Annual & Biennial required. 5. Multi-relations analysis shows 0.81 which is the relatively high interralation between the number of emerged axa and that of naturalized ones. 6. The number of naturalized species has no relation to the lapse of years after construction of open-space. Especially it was identified that weed control in the beginning of construction is very important. On the other hand the relation between Ys and Xp was Ys=1.784Xp+4.646.

A Study on the Distribution Characteristics of NATURALIZED PLANTS: For Gyeongsangbuk-do Area

Byeonggu Yang,Changjun Kim,Hyangju Lee,Wonhyeon Lim J-INSTITUTE 2021 International Journal of Human & Disaster Vol.6 No.2

Purpose: Naturalized plants come in artificially or naturally, producing and spreading large numbers of seeds. Naturalized plants are not culled in the natural ecosystem and coexist in their own way. They have a wide range of tolerance and fast growth rates. Therefore, this study analyzed the differences of naturalized plants in the Gyeongsangbuk-do area by population density, forestland ratio, farmland ratio, land ratio, road ratio, and river ratio. We investigated the correlation with the naturalization index to understand the distribution characteristics of naturalized plants. Method: We conducted one-way ANOVA and multivariate analysis of variance(MANOVA) to determine the differences between the number of naturalized plant species and the items related to the naturalization index. Post-hoc analysis was performed through the Scheffe test method. We performed curvilinear regression analysis to find out the correlation. We used the Spss Statistics 21 statistics program to perform the above statistical analysis. Results: The naturalization index of naturalized plants showed differences in four items: population density, farmland ratio, land ratio, and river ratio, but there were no statistical differences in the two items, such as forestland ratio and road ratio. The farmland ratio did not affect the increase or decrease in the naturalization index. When the land ratio and road ratio increased, the naturalization index was also positively correlated. The river ratio had a positive correlation, but it had a negative correlation again after a certain point. Conclusion: The results of this study are expected to be used as data for selecting priority areas to manage naturalized plants. In addition, the data of this study can be used as basic data to study the naturalization index and environmental change of naturalized plants. However, we propose that comprehensive management for naturalized plants, such as analysis of the inflow path and distribution characteristics of naturalized plants between domestic regions, should be ca rried out continuously at the administrative level of local governments.

Lee Hyang-ju,Cheon Woo-kwang,Lim Won-hyeon J-INSTITUTE 2020 International Journal of Human & Disaster Vol.5 No.1

Foreign plants introduced by overseas exchanges are rapidly transformed into naturalized plants and pose serious threats to biodiversity, including domestic native species. Therefore, this study is based on the flora survey data of 776 map numbers(1200 places) for 12 years from 2006 to 2017, the third to fourth data of the National Natural Environment Survey, the nation’s largest basic research project on the natural ecosystem. By analyzing plant species and naturalized plant species and predicting naturalized plant species and naturalization Index, they can be used as basic data to study environmental changes, or they can be used to set various indicators applying naturalized plants and naturalization Index and to set the upper limit of permit for development activi-ties. Therefore, in this study, one-way ANOVA analysis and MANOVA analysis were conducted to determine whether there is a difference in naturalized plant species and naturalization Index by year, region, altitude, pop-ulation density, GDP, and the ratio of forest to area. There was a correlation between the items such as year, region, altitude, population density, GDP, the ratio of forest to area and the number and naturalization Index of naturalized plants, and the greatest impact on the naturalized plant species and naturalization Index. Curve es-timation regression, multiple regression, and dummy variable regression were performed to find out which items are causing the problem. Through this research, it is thought that the naturalization Index predicted by this study can be used for the issue of Permit on Exclusive use of inter-mountain area altitude standard, which is operated under the Act on Planning, and Use of National Territory, and the Mountain Site Management Act. The natural-ization Index predicted by this study can be used as basic data for setting the upper limit of Permit on Exclusive use of inter-mountain area, or for studying environmental change, or for setting various indicators.

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. The rare plants were 13 taxa There were 3 taxa as critically endangered species such as Impatiens koreana and Magnolia kobus, 2 taxa as endangered species such as Jeffersonia dubia and Lycoris sanguinea var. koreana, 1 taxa as vulnerable species such as Iris minutiaurea, 6 taxa as least concerned species such as Aristolochia contorta, and 1 taxa as data deficient species such as Chloranthus fortunei. 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.

A Study on the CHANGE in Plants of the Wind Power Complex in Mt. Hyeonjong

Changjun Kim,Hyangju Lee,Wonhyeon Lim J-INSTITUTE 2020 Protection Convergence Vol.5 No.2

Purpose: To identify the changes in plants before, during, and after the wind farm construction in Mt. Hyeonjong, we investigated the number of plant species. And we studied the main characteristics of the distribution status in plants family composition, plant life form analysis, Korean endemic plant, rare plant, specific plants by phytogeography, naturalized plant, and invasive alien plants. We compared this data to confirm the change before or after the wind farm construction. Method: We conducted the plants form research 16times in five years. Before the wind farm construc-tion(2014 and 2015), during the wind farm construction(2017 and 2018), and after the wind farm con-struction(2019). Plants changes were analyzed based on the results obtained through field trips. Accord-ing to the national standard plant list, we listed plant names and scientific names(the Korea national arboretum & the plant taxonomic society of Korea 2015). We arranged the classification groups according to the Engler system. Based on the created plants list, the Korean endemic plant, rare plant, specific plants by phytogeography, naturalized plant, and invasive alien plants were extracted and analyzed. Results: The vascular plants decreased compared to before wind farm construction. Compositae was the most common category in plants family composition. Korean endemic plants decreased from 3 spe-cies before the construction to 2 species after the construction. Rare plants were investigated 4 species of Vulnerable species(VU) and 2 species of Least Concerned species(LC). Specific plants by phytogeogra-phy were surveyed the same as a total of 13 species. Naturalized plants decreased from 33 species to 20 species and 26 species. Then, they increased again. Conclusion: As a result of this study, the total plant species, Korean endemic plant, and rare plant growing were reduced in the wind farm section in Mt. Hyeonjong. However, many Naturalized plants and 1 and 2 years old herbage appeared in the area. So we found out that ecological stability was not yet stable, and the disturbance was continuing. In this study, the investigation period after wind farm con-struction is one year, which is a short time to observe and analyze plants succession state, and a follow-up study to examine the growth characteristics of plants more closely is needed.

낙동강 합천창녕보 주변 습지공원지역에 서식하는 자생 초본식물과 귀화 초본식물의 기능 형질 분석

손민정,남기정 한국하천호수학회 2021 생태와 환경 Vol.54 No.4

The two main hypotheses that explain why invasive alien plants successfully colonize new environments are: 1) invasive alien plants are functionally different from native plants in a community, and 2) the plants can adapt well to new environments because they are functionally similar to native plants. The present study investigated the functional traits of naturalized alien herbaceous plants and their native neighbors in a riparian park area near the Hapcheon-Changyeong weir along the Nakdong River to determine which of the two hypotheses applied to the study area. According to the results, leaf functional traits, such as leaf area, specific leaf area, leaf thickness, leaf dry matter content, leaf nitrogen content, and leaf carbon content differed between naturalized alien and native plants, which could be attributed to the higher leaf nitrogen contents in naturalized alien plants than in native plants. The high leaf nitrogen contents are associated with high photosynthetic rates, which lead to effective resource use and rapid growth; therefore, naturalized alien plants growing in the study area were considered to have such functional traits. The results of the present study support the hypothesis that the successful establishment of invasive alien plants is attributed to the functional trait differences between invasive and native plants.
