This study quantified annual uptake and storage of carbon by urban greenspace in institutional lands and suggested improvement of greenspace structures to enhance carbon reduction effects. The study selected a total of five study cities including Seoul, Daejeon, Daegu, Chuncheon, and Suncheon, based on areal size and nationwide distribution. Horizontal and vertical greenspace structures were field-surveyed, after institutional greenspace lots were selected using a systematic random sampling method on aerial photographs of the study cities. Annual uptake and storage of carbon by woody plants were computed applying quantitative models of each species developed for urban landscape trees and shrubs. Tree density and stem diameter (at breast height) in institutional lands averaged 1.4±0.1 trees/100 ㎡ and 14.9±0.2 cm across the study cities, respectively. Of the total planted area, the ratio of single-layered planting only with trees, shrubs, or grass was higher than that of multi-layered structures. Annual uptake and storage of carbon per unit area by woody plants averaged 0.65±0.04 t/ha/yr and 7.37±0.47 t/ha, which were lower than those for other greenspace types at home and abroad. This lower carbon reduction was attributed to lower density and smaller size of trees planted in institutional lands studied. Nevertheless, the greenspace in institutional lands annually offset carbon emissions from institutional electricity use by 0.6 (Seoul)~1.9% (Chuncheon). Tree planting in potential planting spaces was estimated to sequester additionally about 18% of the existing annual carbon uptake. Enhancing carbon reduction effects requires active tree planting in the potential spaces, multi-layered/clustered planting composed of the upper trees, middle trees and lower shrubs, planting of tree species with greater carbon uptake capacity, and avoidance of the topiary tree maintenance. This study was focused on finding out greenspace structures and carbon offset levels in institutional lands on which little had been known.

공익사업 수행시 발생하는 용지보상은 매년 20조원에서 30조원에 이르는 막대한 예산이 투입되고 있는 반면 각종 규정과 업무절차가 복잡하여 업무처리에 많은 인력과 시간이 소요되고 있다. 이에 국토해양부와 같은 중앙부처, 지방자치단체, 도로공사 등 주요 공익사업 사업시행자들은 기관별로 별도의 보상시스템을 구축하고 있다. 하지만 교육과학부, 국방부 등 보상시스템을 사용하지 않는 중앙부처가 대부분이고 기 개발되어 있더라도 시스템 활용도가 낮아 보상시스템을 활용한 보상통계자료의 작성 등이 어려워 매년 국가가 취득하는 공공용지 취득실적 및 규모 등을 파악하기가 어려운 실정이다. 또한 회계시스템과 연계가 되어 있지 않은 시스템이 많아 정확한 보상비 집행실적 추적이 어려워 과세자료 누락으로 인한 세금 누수가 발생하고 있다. 더불어, 과다보상비 책정 및 지급시 이를 체계적으로 추적할 수 있는 전산자료 부재 등으로 보상비 집행의 투명성이 저하될 소지가 있다. 이에 중앙부처, 지방자치단체 및 공공기관별로 용지보상시스템 사용현황을 파악하고 이들을 근간으로 범국가적으로 보상업무를 선진화 할 수 있는 보상자료 통합 관리방안을 제시하고자 한다.

School facilities are important facilities in neighboring residential areas and occupy important physical and social positions. Not using school facility occur to an obstacle to the environment of the local residents and cause a great waste of local land resources, due to its size and location. Therefore, it is necessary to establish a system to identify the cause of the unsold school facility site and to prevent it. On the other hand, it is necessary to make quick use of the unemployed school facility site through conversion of usage.

To estimate annual pollutant loading rate of n-hexane extractable material (HEM) to soil 84 sewage sludge samples were analyzed. The average content of HEM was 27.7$\pm$26.5 g/kg, and ranged from 1.05 to maximum 194 g/kg. According to the number of population of the city the areas were classified as five regions, i.e. big, large, middle, small, and rural area in which the waste water treated plants were grown. The contents of HEM were 22.7$\pm$16.7, 33.3$\pm$25.8, 22.0$\pm$8.7, 31.0$\pm$38.8, 27.7$\pm$25.1 g/kg, in big, large, middle, small, and rural area, respectively. The applicated areas with sewage sludge to land also were divided as 4 sites by US EPA criteria such as agricultural, forest, public contact sites, and reclamation site. The quantitation of annual pollutant loading rate was estimated using a function (99 percentile concentration = $\bar{X}$ + 3$\sigma$) when the application amounts were in dosages of 7,000, 26,000, 18,000, 74,000 kg/ha in 5 regions, respectively. The annual pollutant loading rate of HEM to soil by sewage sludge application was maximum 1,032, 3,832, 2,653, and 10,908 kg/ha in agricultural, forest, public contact sites, and reclamation site, respectively.
