봄이면 우리의 가슴을 설레게 하는 벚꽃의 연분홍색 자태는 4월을 알리는 봄의 전령으로 우리를 기쁘게 하지만 이를해치는 해충의 종류는 한국수목해충목록집에 424종이 등재되어 있어 인간이 벚꽃을 사랑하는 만큼이나 곤충들도 벚나무류를 무척 좋아 하는가봅니다. 1990년 이후 각 도시의 가로수, 정원수로서 경쟁적으로 식재 관리하고 있는 벚나무류에 대한 주요해충으로 복숭아혹진딧물, 뿔밑깍지벌레, 뽕나무깍지벌레, 공깍지벌레, 벚나무응애 등 흡증성해충을 중심으로 이들 해충에 대하여 생리·생태 및 방제법을 간략하게 소개하고자 한다.

A methodology to predict the carbon performance of newly created urban greening plans is required as policies based on quantifying carbon performance are rapidly being introduced in the face of the climate crisis caused by global warming. This study developed a tree carbon calculator that can be used for carbon reduction designs in landscaping and attempted to verify its effectiveness in landscape design. For practical operability, MS Excel was selected as a format, and carbon absorption and storage by tree type and size were extracted from 93 representative species to reflect plant design characteristics. The database, including tree unit prices, was established to reflect cost limitations. A plantation experimental design to verify the performance of the tree carbon calculator was conducted by simulating the design of parks in the central region for four landscape design, and the causal relationship was analyzed by conducting semi-structured interviews before and after. As a result, carbon absorption and carbon storage in the design using the tree carbon calculator were about 17-82% and about 14-85% higher, respectively, compared to not using it. It was confirmed that the reason for the increase in carbon performance efficiency was that additional planting was actively carried out within a given budget, along with the replacement of excellent carbon performance species. Pre-interviews revealed that designers distrusted data and the burdens caused by new programs before using the arboreal carbon calculator but tended to change positively because of its usefulness and ease of use. In order to implement carbon reduction design in the landscaping field, it is necessary to develop it into a carbon calculator for trees and landscaping performance. This study is expected to present a useful direction for ntroducing carbon reduction designs based on quantitative data in landscape design.

There are many existing trees are to be damaged by reconstruction of large housing estates. The purpose of this study was to find out sustainable conversion methods of Greenbank system by UR Agency. Greenbank system is divided 3 parts as Preserving, Replanting, Recycling of Existing trees. Literature and institutional review and site survey of 5 reconstruction housing estate were the methods for the following findings. The results are follows. Firstly, Because of feasibility of reconstruction, existing trees are preserving at boundary space of reconstruction housing estates. Secondly, existing trees are preserving at inner space for remember of resettlement as symbolic trees. It is conformed by residents participation with UR Agency and city official. Thirdly, Preserving and replanting trees are recorded signboard in the reconstruction housing estates, and preserving of trees are developed as Green workshop by residents. Fourthly, Besides Preserving and Replanting trees, the other trees are recycling as bench, play equipment, planter, etc. And it is remained symbol of reconstruction housing estates. Fifthly, District planning as a institutional, Guidelines as a noninstitutional method are very efficiently for preserving trees. But a part of this study can be adapt reconstruction housing estates in Korea. The results of this study are expected to serve some clue for dealing with the practice of sustainable conversion in housing estates.

Change detection has been recognized as one of the most important steps to update city models. In this study, we thus propose a method to detect urban changes from two sets of LIDAR data acquired at different times. The main processes in the proposed method are (1) detecting change areas through subtraction between two DSMs generated from the LIDAR sets, (2) organizing the LIDAR points within the detected areas into surface patches, (3) classifying the class of each patch such as ground, vegetation, and building, and (4) determining the kinds of changes based on the properties and classes of the patches. The results which were obtained from the application of the proposed method to real data were verified as appropriate using the reference data manually acquired from the visual inspection of the orthoimages of the same area. The probability of success in change detection is assessed to 97% on an average. In conclusion, the proposed method is evaluated as a reliable, and efficient approach to change detection and thus the update of city model.

This study reflects our conviction that the maintenance of the landscape plants in apartment housing areas has appeared as an important factor. The defects ratio of the landscape plants shows high in the study, which tells us a serious situation were facing in consideration of the quality of residential Life. Methods for the effective maintenance of the landscape plants are recommended as follows; First, the landscape plants in apartment housing areas should be maintained by a specialist in landscape architecture. Second, the co-operative maintenance between inhabitants and specialists is required. Third, the over-all understanding of the landscape plants should be improved.

This paper categorized the functions of and investigated the characteristics of planting in Pyeonghwa Park near the Seoul World Cup Stadium as a preliminary study for improving tree planting in the park. The functions of planting were deduced based on related theoretical studies and an analysis of the intention of design and environmental factors. The characteristics of planting were analyzed after drawing the distribution and stratification of dominant planting species and setting samples by function. The functions of planting were classified into natural landscape planting, buffer planting, and shade planting. For dominant planting species, pine trees and elm-like trees have been widely observed while various species in addition to pine trees in natural landscape planting areas have been introduced in terms of the function of planting. These trees that were randomly planted before the park was developed have been obstacles in the formation of natural landscapes. For buffer planting and topographical correction, tall trees were planted. However, it seems that comprehensive complementary measures should be taken on the under-story planting.

We estimated and compared C storages and annual $CO_2$ uptakes by 9 dominant tree species planted along the streets. DBH and age by tree species were measured in the sites selected considering the planting status and distributions of tree species, and biomass, C storage, growth rate, and annual $CO_2$ uptake were estimated for each species. As a result, L. tulipifera, M. glyptostroboides, P. occidentalis were classified into fast-growing group, P. serrulata, G. biloba, Z. serrata, S. japonica, A. palmatum showed intermediate growth rates, and P. densiflora was slow-growing. Average C storage per tree was 205kgC/tree and ranged from 518kgC/tree(L. tulipifera) to 41kgC/tree(P. densiflora). Average annual $CO_2$ uptake by urban street trees over their lifespan ranged from $7.6kgCO_2$/tree/y to $99.1kgCO_2$/tree/y and L. tulipifera was the greatest, followed by glyptostroboides and P. occidentalis, and P. densiflora was the lowest. Total annual $CO_2$ uptake by all street trees in Gyeonggi-do, estimated based on the annual $CO_2$ uptake by each species, was as small as approximately 0.67% of that by forest in Gyeonggi-do. However, urban trees are still important because forest area continues to decrease and urbanization occurs annually in Gyeonggi-do, and should be managed considering their multi-functional aspects, including mitigation of heat island effect and building energy saving(indirect $CO_2$ uptake).

This study aimed to identify the optimal street tree planting method to improve the summer thermal environment in Seoul, Republic of Korea. The effects of road direction and street tree planting patterns on urban thermal environments using ENVI-met simulations were analyzed. The 68 scenarios were analyzed based on four road directions and 17 planting patterns. The results showed that tree planting had a reducing air temperature, mean radiant temperature, human thermal sensation (PET and UTCI). The most effective planting pattern among all scenarios was low tree height (6m), wide crown width (9m), high leaf area index (3.0), and narrow planting interval (8m). The largest improvement in the thermal environment was the northern sidewalk of the east-west road. Since this study used computer simulations, the difference from real urban spaces should be considered, and further research is needed through field measurement and consideration of more variables.
