본 논문은 우리나라 임도사업의 법적, 제도적 기틀을 위한 기초자료를 제공하기 위하여 임 도사업의 경험이 축적된 일본의 민유림 임도사업에 대한 정비방침, 보조체계, 사업체계 및 관련법규에 대하여 자료를 정리·고찰하였다. 그 결과, 일본의 민유림 임도사업은 다양한 시 대적 요청에 따라 법적·제도적 기틀을 마련하여 실행하므로서 효율적인 임업경영의 전개, 삼림의 적정한 유지관리, 산촌지역의 진흥 및 생활환경 등에 일익을 담당하고 있다. Japan is considered to have accumulated much experience of the maintenance, financial support. construction, and related law system of non-national forest road. These data were collected and reviewed to provide the basis of the legal and institutional framework for the forest road construction of Korea. The results show that the non-national forest road plays a key role in the development and enhancement of rural areas' surroundings as its legal and institutional systems are brought to effect and meet the period's requires.

전근우,유남재,차두송,이명종,박완근,한상균 강원대학교 삼림과학연구소 2000 Journal of Forest Science Vol.16 No.-

강릉시 시범 공설묘지 조성사업은 경사 30˚ 의 표고차가 심한 산지를 절 · 성토하여 계단식 묘역단을 조성하는 공사로 수직고 15m이상의 대절토 및 성토부가 산재하고 있다. 특히 묘역단장후 주변 유입수 및 표면 유출수에 의한 비탈면 붕괴, 묘역단 유실 등의 피해가 발생할 경우 보수 또는 보강이 사실상 어려운 실정이며, 사회적 여론으로 확대될 가능성이 크므로 비탈면 보호에 필요한 녹화공법을 검토하였다. 구체적인 연구내용으로는 설계도면 및 현장답사를 통한 문제 비탈면 추출, 비탈면의 물리적 특성과 식생의 생육상황 파악, 비탈면 주변부의 식생조사와 유용식생 선발, 비탈면의 토양조건 분석 및 비탈면 토사의 기본물성 조사 등이며, 이를 기초로 하여 비탈면 현황 및 문제점을 파악하고, 그 대안을 제시하였다. The construction of a public cemetery in Kangnung city includes terraced graveyard with cutting or banking in mountain which has severe altitude differences with a slope of 30˚. Therefore, there are scattered cutting and banking sections with vertical height more than 15m. Especially, if the slope failure or the loss of a graveyard happens after graveyard establishment due to surface flow and inflow around, it is difficult to repair, causing serious public censure. Accordingly. revegetation works were examined that need protection of slope. The specific content of the study was the selection of slopes requiring special care through blueprint and field investigation the measurement of the physical property of slope and the situation of vegetative growth, the investigation of vegetation in slopes and the selection of vegetation, and the analysis of soil condition of slopes and the physical condition of slope sediment. On the basis of investigations some alternatives were proposed.Key words: public cemetery, slope protection works, revegetation works

Cha, Du-Song,Oh, Jae-Heun,Yi, Jae-Seon,Bae, Young-Soo Institute of Forest Science 2007 Journal of Forest Science Vol.23 No.2

This survey was carried out to investigate the utilization situation of fire-wood boiler by the questionnaire and personal interview on rural and mountain households of Gangwon province from 1998 to 2005. The questionnaire include 7 questions on installation, 7 questions on fuel, 3 questions on use, and 3 questions on improvement. Each question was analyzed by percentage to investigate the use situation. This survey indicated that the general problems in use of fire-wood boiler are fuel purchase, collection and transportation, that the development of the household heating boiler using wood-based forming fuel which is cheap, small volume, easy handling, convenient purchase and high heat efficiency could be an alternative to improve the problems and that the continuous expansion of the supply of fire-wood boiler can prevent the devastation of forest through the regulation of imprudent fuel supply. Although the financial aid plan on the installation of fire-wood boiler is in active, many petty households in rural and mountain areas lose a chance to install the fire-wood boiler due to the unsatisfactory information. Thus, it will be desirable for municipal government to prepare the information plan to offer the equal chance and condition to all households in rural and mountain areas and to increase the financial aid for the continuous supply of fire-wood boiler.

Planning of Forest Road Network for Palm - Form Working System by Aerial Photographs

Du Song Cha 한국산림과학회 1990 한국산림과학회지 Vol.79 No.1

The goal of forest management is to maintain the difficult equilibrium between economic timber production and the service production function of forests. Forest road is prerequisite for accomplishing the goal of forest management. Accordingly, this paper deals with the planning of forest road network for palm-form working system by aerial photographs. The results obtained are summarized as follows : 1. The 50 blocks, the most fundamental unit of the palmform working system, were established by the compartment border, topographic conditions and standard size considered to the rotation and or the cutting cycle. 2. Based on the planning of forest road related to skidding methods, topographic conditions and silvicultural system, constraint conditions ware evaluated. The results suggested that high-density forest road and skidding method by truckcrane were adequate for palm-form working system, and contour road should be provided to improve the skidding effect for group selection cutting system of the natural broadleaved forest within the unit blocks. 3. All of the 50 unit blocks were classified into 6 groups based on shape and land form, and then the representative unit blocks were selected from each group. 4. The stand volume(m/ha) of each representative unit block was estimated by a linear regression equation, based on the data interpreted by aerial photographs and measured from ground survey. In addition, all unit blocks were classified into 8 forest types by aerial photographs and cluster and principal component analysis corresponding to the planning of forest road network and cutting schedule. Attributes of cluster and principal component analysis were the number of saw timber and pole timber per ha and the corresponding coefficient of variation of each unit block by photo interpretation, 5. The optimum forest road was automatically planned by using digital terrain model, satisfying two parameters in the unit block. One was establishment condition, and the other was restraint condition, the establishment condition indicates the allowable gradient and the forest road density, and the restraint condition contains the average skidding distance. the explorative index, the ratio of incapability skidding area, the standard deviation of skidding distance and the weighted average skidding distance. The results showed that the topographic shape was of great importance in setting the beginning and end point. According with the land form, it is recommended that the upper and the lower road should be located in the steep terrain, but one forest road should be constructed in the rectangle hilly and even terrain, This combination showed s-curve form. In the case of all land form with triangle pattern of unit block, the optimum forest road should be considered relationships between the adjacent unit blocks. 6. The double steps which means the upper and the lower road should be located within the unit block. Also the connecting road which connects the upper with the lower road, between hillsides, and between watersheds should be determined. Consequently, the optimum forest road should be planned all of the forest area composed of small watersheds, considering the natural and managerial conditions.
