본 연구는 지리산국립공원 자연관찰로의 효율적인 관리를 위한 기초정보를 제공하기 위해 자연관찰로 이용자를 대상으로 한 설문조사를 실시하였다. 이용자들의 사회경제적 특성은 다른 국립공원 방문객을 대상으로 한 기존의 연구결과와 유사한 것으로 나타났다. 자연관찰로에 대한 정보에 대해서는 응답자의 44.4%와 22.6%가 각각 다른 이용자와 공원 안내판을 이용하는 것으로 분석되었다. 유평과 하동 지역은 응답자의 대부분이 가족과 함께 방문하였으나 중산리와 백무동 지역은 단체관광의 비율이 가장 높게 나타났다. 자연관찰로 방문의 주된 목적은 지역별로 다르게 나타났는데 유평과 하동 지역은 도시로부터 벗어나기 위함이었고 중산리와 백무동 지역은 하이킹과 등산을 즐기기 위해서였다. 전체 응답자의 63.7%는 자연관찰로의 길이가 적당하다고 응답하였으나 40% 정도의 응답자는 자연관찰로의 길이는 2km 이하가 적당한 것으로 인식하고 있었다. 전체 응답자의 37.5%가 자연해설프로그램을 체험할 수 있는 다른 프로그램에 참여하기를 희망하고 있는 것으로 나타나 지리산국립공원 자연관찰로의 기능증진이 강구되어야 할 것으로 나타났다.

The purpose of this study was to provide basic information for judging cultivation suitability by analyzing the growing environment of Zanthoxylum schinifolium habitats in Gyeongnam-do. The site environment, soil environment and community structure were analyzed in habitats of 7 cities and counties. The habitats were distributed in slopes at 87~764 m above sea level. It was found habitats was distributed in the well-drained soil with high content of sand and soil texture of habitats was mainly loamy sand and sandy loam. Bulk density and particle density were 0.89 g/cm3 and 2.65 g/cm3 on average, respectively. The soil had 5.10 of pH, 6.41% of OM content, 0.29% of TN content, 3.84 ppm of available P content, and CEC of 12.3 cmol+/kg on average. The habitats were classified into four communities (Z. schinifolium-Lindera erythrocarpa, Castanea crenata-L. erythrocarpa, Pinus densiflora-Z. schinifolium, P. thunbergii-Z. schinifolium by clustering analysis. Ecological niche breadth was highest of 0.885 in site Ⅵ (Tongyeong) and lowest of 0.608 in site Ⅴ (Goseong).

The aim of this study was to investigate the plants in Yongjibong Natural Recreation Forest before construction, to provide basic data that can be used for various purposes. The survey was conducted on the planned recreational forest sites from June to September 2020. The numbers of flora are summarized as follows: 348 taxa, 95 families, 234 genera, 308 species, three subspecies, 30 varieties, and seven forma. The Korean endemic plants were of nine taxa, including Fagus engleriana, Celtis choseniana, and Broussonetia x kazinoki. The rare plants were of six taxa, including Juniperus chinensis var. sargentii, Hylotelephium ussuriense, Thuja orientalis, and F. engleriana; however, Juniperus chinensis var. sargentii, H. ussuriense, T. orientalis, and Iris ensata var. spontanea were planted species. The floristic regional indicator plants (unique plants) found in this survey area were of 33 taxa, comprising three taxa of grade V, four taxa of grade IV, nine taxa of grade III, four taxa of grade II, and 13 taxa of grade I. The naturalized plants were of 26 taxa, including Rumex crispus, Phytolacca americana, and P. esculenta. Among the naturalized plants, it is necessary to prevent the spread of Ambrosia trifida, Bidens frondosa, and Tagetes minuta through continuous monitoring.

This study was conducted to provide basic data for the establishment school forests in order to utilize school forests as a place for environmental education through analyzing the planting status in elementary schools located in Changwon-city. School forests including meditation forest were the largest in Yongho elementary school (below e.s.) in meditation forest school and Dogye (e.s) in normal school. Jehwang (e.s.) and Sangnam (e.s.) showed the most abundant green area given for the management per member. The number of planting species and individuals in school forests differed greatly by elementary schools. There was also a difference in the number of planted species for establishment of meditation forest. There were no significant difference the concordance rate between the plants planted in the school forest and the plants mentioned in the textbook between meditation forest schools and normal schools. Index of ecological health averaged 3.2 for meditation forest schools and 2.4 for normal schools, which is the result of increase in green area and green rate due to the establishment of the meditation forest.

The purpose of this study was to provide basic information for rational management plans for sustainable conservation and utilization by comprehensive analyzing the flora distributed in Yongchu valley, Changwon-si. The flora of Yongchu valley were summarized as 319 taxa including 93 families, 212 genera, 285 species, 3 subspecies, 6 forms and 25 varieties. The endemic plants were 5 taxa such as Chrysosplenium pilosum var. fulvum, Impatiens koreana, Lespedeza maritima, Thalictrum acteifolium and Weigela subsessilis. The rare plants were 11 taxa including I. koreana, Prunus yedoensis and Magnolia kobus.

This study was carried out to provide preliminary information to grasp how many particulate matter (PM) which is a problem in urban area are absorbed and removed by street trees. The morphology, size and element composition of PM deposited on leaves of five street trees (Quercus glauca, Q. myrsinaefolia, Ginkgo biloba, Prunus serrulata var. spontanea, and Pinus densiflora) in Jinju city, South Korea were analyzed. The size of PM was classified into three as PM2.5 (0.2~2.5 μm), PM10 (2.5~10 μm), and PM100 (10~100 μm). The element composition of PM deposited on the leaves at the study sites mainly comprised of O, C, N, Si, and Al. The PM at industrial area and university campus was irregular and spherical shape, respectively. Total PM accumulated on the leaf surfaces of P. densiflora was 71.65 μg/cm² at industrial area and 40.66 μg/cm² at university campus, which was significantly higher than the other species. The ratio of PM2.5, PM10, and PM100 deposited on the leaves was 9.2%, 37.0%, 53.8% at industrial area and 15.8%, 27.1%, 57.1% at university campus, respectively. P. densiflora deposited the most PM2.5, PM10 and PM100 in leaf wax at the study sites, which was significantly higher than the other species.

This study was conducted to provide the basic information for making the plans on reasonable conservation of inland wetlands by analysis the vascular plant and life form at Dongpan and Sannam wetland in Junam reservoir, Changwon City.
