본 연구는 효율적인 임내도로망 구축을 위한 정책적 기초자료를 제공하고자 산림청 산하 5개소의 임도시설시범단지를 대상으로 복합임도망의 적정밀도를 산정하였다. 그 결과, 복합임도망의 적정밀도는 10.1~15.9 m/ha이었으며, 단일 규격의 간선임도망은 8.4~12.4 m/ha로 나타났다. 이를 기준으로 임도개설비용을 추정해보면, 단일규격의 간선임도망에 비해 약 1~8% 낮게 측정된 반면, 임도밀도는 20~30%가량 증가하였다. 또한, 대상지의 생산예정재적과 집재비용이 증가함에 따라 복합임도망의 적정밀도도 증가하였으며, 특히 고규격의 간선임도 밀도가 급격히 증가하였다. 한편, 경사가 급한 지역일수록 저규격의 작업임도 밀도가 상대적으로 증가하는 경향을 보였다. This study was conducted to provide the basic policy information for establishing efficient forest-road networks. Synthetic forest-road networks that consist of main and spur roads and forest-road networks with only main road (hereafter called “main-road network”) were planned for the five forest-road experimental districts of Korea Forest Service in this study. Road density of the synthetic forest-road networks was calculated and compared with the road density of the main-road networks. The results showed that the optimum road density of the synthetic forest-road networks was 10.1~15.9 m/ha, and the road density of the main-road networks was 8.4~12.4 m/ha. The construction cost of the synthetic forest-road networks was estimated about 1~8% lower than the main-road networks, while the road density was 20~30% greater than the main-road networks. As timber volume and hauling cost increased, the optimum road density of the synthetic forest-road networks increased, within which the road density of highstandard main road rapidly increased. On the other hand, the spur road density increased with slope gradient.

In 2000, a total of 23,794ha of forest was lost due to the East Coast forest fire, and about 70% of the damaged area was concentrated in Samcheok. In 2001, artificial restoration and natural restoration were implemented in the damaged area. This study was conducted to understand the current vegetation structure 21 years after the restoration of forest fire damage in the Samcheok, Gumbong Mountain area. As a result of classifying the vegetation community, it was divided into three communities: Quercus variabilis-Pinus densiflora community, Pinus densiflora-Quercus mongolica community, and Pinus thunbergii community. Quercus variabilis, Pinus densiflora, and Pinus thunbergii planted in the artificial restoration site were found to continue to grow as dominant species in the local vegetation after restoration. As for the species diversity index of the community, the Quercus variabilis-Pinus densiflora community dominated by deciduous broad-leaf trees showed the highest, and the coniferous forest Pinus thunbergii community showed the lowest. Vegetation in areas affected by forest fires is greatly affected by reforestation tree species, and 21 years later, it has shown a tendency to recover to the forest type before forest fire. In order to establish DataBase for effective restoration and to prepare monitoring data, it is necessary to construct data through continuous vegetation survey on the areas affected by forest fires.

Of the countries where Korea has advanced for overseas afforestation investments, Indonesia might be the most important country. As the end of 2010, nine Korean companies have been implementing afforestation projects in Indonesia, covering a total area of one hundred and fifty thousand hectares roughly. Following the Memorandum Of Understanding (MOU) on afforestation investment covering five hundred thousand hectares (A/R CDM / industrial afforestation) signed between Korea and Indonesia, the two countries concluded in 2009 an additional MOU covering two hundred thousand hectares for biomass afforestation, thus securing a total afforestation area of seven hundred thousand hectares. Further it was guaranteed that afforestation license would have validity for maximum 95 years, which laid the foundation for long-term stable investments for afforestation projects. Forest law of Indonesia consists of Presidential decree and Governmental decree as superior regulations and Minister's decree as subordinate regulations, being made up of total 17 chapters. Forestry Minister's decree was amended at end of last year, as regards license for exploitation of timber and forestry products in afforestation area. In the past, such license to develop and use timber and forestry products had been granted under Forestry Minister's decree No. P 11 / Menhut-II / 2008. After the amendment in 2010, however, the ground was shifted to Forestry Minister's decree No. P 50 / Menhut-II / 2010, trimming the procedure to obtain afforestation license into a little simplified one.

The purpose of this study is to review the laws on foreign investment and the changed licensing procedures in Laos and to provide the data for basic understanding of foreign forestation investment in Laos. The conclusions are as follows. The Laos government has been consistently trying to promote foreign investment. In particular, in 2004, the 「Law on the Promotion of Foreign Investment」 was legislated. In 2009, the Foreign Investment Promotion Act and the Domestic Investment Promotion Act to incorporate the principles of the 「Law on Investment Promotion」 were enacted. In Laos, the country’s land is owned by the nation’s community and maintained by the government. Therefore, through the procedures for registration of land, land can be conceded or leased. The ways to invest are joint ventures (where at least 10% of the total capital investment has to be made), foreign sole investment (where the investor must have a minimum capital of $100,000 or more), joint venture agreement and etc. Lastly, the forestation licensing procedures in Laos are carried out in the following order: site selection, business investments feasibility studies, environmental and social impact assessment, forestry permit application.

본 연구는 임도의 재해위험 등급을 구분하기 위한 평가표를 제시하고자 수행되었으며, 이를 위해 임도의 재해에 영향을 미치는 인자들을 선정하고 산림공학 전문가들을 대상으로 AHP 설문조사를 실시하였다. 평가항목은 전문가집단의 자문을 통해 크게 자연환경, 인문·사회환경, 임도의 구성요소로 구분하였으며, 총 21개의 평가인자로 구성하였다. 설문조사결과를 바탕으로 각 평가항목에 대한 가중치 분석을 실시하였으며, 분석결과 임도의 구성요소 항목 중 배수시설이 가장 높은 가중치를 점하고 있는 것으로 나타났다. 한편, AHP 분석결과를 바탕으로 각각의 평가항목에 대한 평가기준과 평가점수를 부여하여 평가표를 작성하였다. 도출된 평가표를 현장조사에 적용시킨 결과 최고점은 78.8점, 최저점은 42.7점, 평균점수는 61.8점으로 나타났다. 산정된 점수를 바탕으로 전문가 집단의 회의를 통해 임도의 재해위험 등급을 4등급으로 구분하여 제시하였다. The purpose of this study is to provide basic data for forest roads management by using AHP methodology to group the grade of disaster risk. In addition to this, a field study was performed at 114 targeted points on forest roads where there are high risks of disaster occurrence. The results of the field survey and the analysis of AHP were compared to provide the degree of disaster risks. It shows that the drainage facilities occupied the highest weighted value. Meanwhile, based on AHP analysis data, evaluation chart was created by providing evaluation criteria and evaluation score to each evaluation items. As a result of applying the evaluation chart to the field survey data, the highest score was 78.8 and the lowest score was 42.7 with the mean score of 61.8. Finally, through the experts` consultation based on calculated scores, this study proposed four different groups of disaster risk on forest roads.
