This study was conducted to analyze the relationship between planted plants and immigration plants by monitoring the wildflower garden constructed at Seoul Samgaksan Elementary School. The results of this study are as follows: First, plants planted in the garden 32 taxa, except for weakened only 1 taxa (Clematis patens), the remaining plants maintained or increased their populations. Among maintained Plants, that did not volume growth were 6 taxa and volume growth on the spot were 5 taxa. 15 taxa were spread around the planting area and 5 taxa spread sporadically to unpredictable areas other than the planting area. Although most of the planted plants show good growth, no special management is required, but Lonicera japonica needs the density management that cuts off the stem in the early spring and 5 sporadically spreading taxa, the planting intent of garden is attenuated, so remove the root when new leaves come out in spring. Second, the total number of plants transferred after 2 years of wildflower garden constructed were 83 taxa total, which is 2.6 times that of planted plants. The seed disseminule form was analyzed as 52% barochory, 27% anemochory&hydrochory, 16% autochory and 5% zoochory. Also about 43% of the transferred plants were estimated to been imported from soil seed bank. Third, we classified immigration plants into largely native plants and naturalized plants. The native plants were transferred to more than naturalized plants: 65 native plants, 1 cultivated plants and 17 (22%) naturalized plants. The results of the monitoring of the rooftop garden ‘Choroktteul’ in Seoul City Hall showed that there were differences in the type and number of the immigration plants depending on the distance and quality of the surrounding greenery. Fourth, the management method of immigration plants is divided into three categories: elimination, transplantation, and utilization. The 39 taxa were selected for the elimination: Invasive alien plants among naturalized plants, fast spreading plants, plants that expand sideways with rhizomes, and plants that interfere with the growth of planted plants: grow to over 1 meter in height and climbing plant. The elimination period should be dry, clear, windy day, remove the root without any residue. The transplanted plants are 18 taxa, tree, plants not suitable for habitat, and in elementary school textbooks. It is a group of 26 taxa which are used in the garden: for landscape that plants have ornamental values (flowers, leaves, and autumn colors etc.) but do not attenuate the intent of the garden, and for groundcover that plants have low plant height and fast spread. It is also possible to prevent immigration plants when you are mulching or planting plants densely populated areas when making a garden.

본 논문은 재난재해와 방사선 오염으로부터 안전한 농작물 관리를 위한 플랫폼, 그리고 식물 생장 모니터링 시스템 을 제안하였다. 또한, 식물생장을 모니터링하여 식물공장 내에서 생장하는 식물의 크기를 효율적으로 측정할 수 있는 시스템을 개발하였다. 본 연구에 따른 기대효과는 첫째, 자연재해와 방사능오염 감시를 통해 신속하고 정확한 대처 기능으로 농산물 품질 과 생산성 향상을 가져올 수 있다. 둘째, 식물의 크기 측정 데이터를 유지 관리하는데 소요되는 시간을 절약하여 경비 를 절감할 수 있다. 마지막으로 식물 공장 관리자의 작업 효율을 향상시킬 수 있다.
