  • This study is conducted to evaluate the effects of containerized landscape tree production methods on post-transplant stress. Two types of container such as plastic pot(pot), fabric growing bag(bag) were adopted to restrict tree roots. Each types of containers was divided into seven sub-types. One traditional production method was included as comparison. Two landscape woody plants species (Magnolia denudata, Albizzia julibrissin) were implanted in the 7 sub-types of container. After one or two growing season in the container, each types of container trees was transplanted. Half of the trees were transplanted in the mild spring season, and another half of trees were transplanted in the improper summer season. The data were collected on the crown wilting ratio and trunk die-back ratio. The result of the analysis based on these data were as follows; 1) The container production methods were lower than the traditional production methods by 3 times in the average wilting ratio of summer season's transplanting point. 2) Post-transplant stress was more successfully mitigated, in case the "pot" type as was the "bag" types of container. 3) The effective and economic way of mitigating post-transplant stress by container production methods was selecting container plants of vigorous and deep root systems. 4) The "pot" type of container was to restrict tree roots more successfully, But, winter chilling and low temperature attacked the "pot" type tree's twigs and suckers. These results indicated that "pot" grown container plants should managed carefully during the winter after transplanting. Based upon the results of this study, a subsequent research on the development of container material, growth type of the container trees, and other maintaining method will be required.es, and other maintaining method will be required.

  • 환경영향평가 시 개발사업으로 훼손되는 수목의 약 10%를 이식 또는 재활용하도록 하고 있으나, 이식 시 여러 가지 문제점들이 제기되고 있다. 본 연구에서는 이해관계자를 대상으로 이식 시 발생하는 문제점에 대한 인식을 파악하였다. 2020년 10월 9일부터 25일까지 실시한 설문조사에 협의기관, 검토기관, 사업자·대행자 그룹별 각각 36명, 44명, 83명(총 163명)이 참여하였다. 세 그룹 모두 개발사업으로 인한 훼손이 심각하므로 개발 부담금이 증가하더라도 훼손 수목의 일부를 이식하는 것이 필요하다고 응답하였다. 가장 심각하다고 응답한 문제점은 고사율이었다. 고사 시 대체 방안으로 세 그룹 모두 동일한 수종과 수량을 식재해야 한다는 응답 비율이 높았다. 고사율을 줄이기 위해 이식 수목은 크기가 작은 것을 이식하고, 이식 수종은 식재종과 조경 수종을 포함하여 확대시키고, 이식 수목량은 자생 수목량 대비 이식 비율을 산정하자는 응답 비율이 높았다. 관리자를 별도로 배치할 필요가 있다고 응답한 비율도 높았다. 본 설문조사의 결과는 훼손 수목의 이식 시 발생하는 문제점을 개선하기 위한 기초 자료로 활용할 것이다.

  • 우리나라는 산림이 64%에 이르기 때문에 개발사업에 의한 산림훼손이 불가피하다. 이에 대한 방안으로 환경영향평가 제도에서는 훼손되는 수목량의 10%를 재활용 및 이식하도록 하고 있다. 그러나 환경적 요건이 고려되지 않아 이식성공률이 저조하고 가이식장 운영이 잘 되지 않아 수목이 고사하는 등 문제가 지속적으로 발생하고 있다. 이러한 실태를 파악하기 위해서는 현장조사가 필수적이나 시간 및 공간적 한계가 존재한다. 본 연구에서는 원격탐사 기반의 식생지수를 적용하여 개발사업으로 인해 발생하는 이식수목 현황의 시계열적 변화를 탐지하고 원격탐사의 적용성 평가를 목적으로 한다. 이를 위해 위성영상을 분석하여 가이식장 면적을 구축하고 이식 전, 후 식생지수의 시계열 변화를 분석하여 식생 상태를 도출하였다. 연구 결과는 현장조사를 통한 이식수목의 고사율 및 활력도와 위성영상 기반으로 한 가이식 전 후의 식생지수 변화 분석의 결과가 유사한 경향성을 나타내었다. 이에 따라 가이식장에 수목 이식 후에는 가이식장 범위의 녹색 식물의 상대적 분포량과 활동성이 증가하고 시간이 지남에 따라 수목 고사 및 활력도 감소로 인해 낮아지는 것을 규명하였다. 본 연구를 통해 위성영상에 기반한 이식수목 평가 방법을 제시하였으나, 실제 평가에 적용하기 위해서는 보다 정량적인 방법론을 개발할 필요가 있을 것으로 사료된다. 본 연구는 원격탐사 기법인 위성영상과 식생지수를 활용하여 보다 전국에 분포한 이식수목의 변화를 탐지하여, 개발사업으로 인해 시행되는 환경영향평가 제도의 수목 이식이 제대로 수행되고 산림 파괴에 효과적인 저감 대책을 마련하는 데 기여할 수 있을 것으로 기대된다.

  • This study investigates, analyzes, and summarizes Dansplantation techniques and methods through practical methodology centering on fieldwork in order to present effective planting methods for large trees that have important significance. The conclusions are as follows : 1. The transplantation process of a large tree generally consists of the stages of digging up a tree, manufacturing a carrier frame, loading the tee on a vehicle, transporting, transplanting the tree, installing a strut and maintaining and managing the new transplant. In addition, planting a tree on a mounted place includes the primary procedures of trimming out the root, and preparing for transplanting the tree on a mounted place, as well as the secondary work of trimming out the root, transplanting a tree on a mounted place, maintenance and management. 2. In order to decide on a transplantation method for a large-sized tree, a structure calculation has to be performed first. That is, one must calculate the weight of the tree and the allowable stress of the strut (H-beam, etc.) fhst and then decide on the upper method through computer modeling based upon this structural calculation. 3. As a result of the analysis of a transplanted tree using the life soil method, it was confirmed that large quantities of feeder roots had developed around the root within a short time after the transplantation. The life soil method has proven to be very effective for transplantation of large-sized trees. 4. As for the production method of an H-beam strut frame, it was found that the manufacturing process and disassembly process were simple and proper; therefore, the H-beam frame is an appropriate structure to be used in the transplantation of large trees. 5. The concavo-convex method, which consists of filling the life soil in the concavo-convex area around the root, was found to be a method that promotes the growth of feeder roots within a short period of time and saves the supply of water at the same time.

  • Enlargement of street tree planting area is the proper and effective solution to reduce carbon dioxide. This solution bases on the ability of carbon storage and uptake by tree metabolism. However, the circumstance of road side has fatal disadvantages in tree metabolism such as growth and maturity because cutting and filling of roadsides cause unnatural soil composition. In this point, early rootage of street tree is the main factor of reducing carbon dioxide. This study aimed to find a appropriate transplantation planting method for sound and rapid rootage of street tree. For the study, Korean Mountain Ash(Sorbus alnifolia) were used for experimental groups. The groups were categorized by three groups such as trees produced on container with mulching treatment, trees produced in outdoor with mulching treatment, trees produced on container with weeding treatment. Each group consisted 10 trees with same size and transplanted in experimental site. Five months after transplanting, each group was estimated the biomass and carbon storage through a direct harvesting method. According to results of the study, the carbon storage of trees produced on container with mulching treatment is 42% more than trees produced in outdoor with mulching treatment. And the carbon storage of trees produced on container with mulching treatment is 19.5% more than trees produced on container with weeding treatment. These results may imply that transplantation of container produced tree with mulching treatment is the most rapid rootage among other groups. The weeding treatment is more effective than mulching treatment for rapid rootage of street trees.
