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.

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.

본 연구는 임도사업의 계획과 유지관리 단계에서 임도 관리자 집단의 의식성향을 파악하여 체계적인 임도정책 수립을 위한 기초자료를 제공하기 위하여 수행하였다. 임도의 계획과 유지관리에 대한 설문조사 결과, 임도 노선의 계획시 고려사항으로는 육림작업, 산지재해 예방, 목재수확 등의 항목에서 높은 중요도를 보였으며, 간선임도에 대한 선호도가 가장 높게 나타났다. 또한 임도 유지관리 작업의 적절성에 대해서는 두 집단 모두 인력 및 예산부족으로 인한 어려움(92.9%)이 있다고 응답하였다. 임도의 개설로 우려되는 주요 피해형태로는 사면붕괴로 인한 인명피해, 사유지 통행에 대한 분쟁 등의 순으로 나타났으며, 현재 실행하고 있는 임도 유지·관리작업의 주요 내용으로는 배수시설의 정비와 노면정비가 높게 나타났다. 임도시설에 대한 주요 보완사항으로는 배수시설, 비탈면 녹화와 안정에 대한 응답이 높게 나타났다. This study was conducted to provide the basic policy information for systematic forest road planning and maintenance management by surveying two different administrator groups. The survey results showed that the high priorities of forest road planning were silviculture, disaster prevention, and timber harvesting, and main forest road type was preferred for future use. Also 92.9% of the respondents expressed difficulties due to insufficient manpower and budget. The expected damage types due to forest road construction were threat-tolife by slope failure and dispute on crossing private land. The current main maintenance tasks on forest roads included drainage and road surface maintenance works. Main forest road facilities that should be needed after the construction were installation of additional drainage structures, and slope revegetation and stabilization.

Forest roads of 16,424㎞ have been constructed as infrastructure for efficient management of forest. The demand of forest road have been also increased steadily with SOC conception for forest management and wood production. But, accuracy verification by completion drawing of forest road needed aspects extration of geographic information to sound like forest road construction and completion drawing. However, verification for completion drawing has not ascertained. This study carried out the evaluation for position accuracy about constructed forest road in Chungcheongnam-do for evaluating horizontal position accuracy of completion drawing of forest road. In result, first of distance of completion drawing and real route designed completion drawing longer than the real route as Gongju 83m, Seosan 66m, Nonsan 27m and Dangjin 19m, respectively. Second, RMSE by point-correspondence was 11m~14.7m, buffering analysis appeared difference of 18~24m. Finally, index of shape was the similar completion and real route through 6.5~7.4 and data information of forest road corresponds to be perfect. For such reasons, the existing completion drawings have a problem that it cannot use graphic information for drawing digital map according to the regulation, and there is an urgent need for improvement to solve this problem in the process of design and construction.

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.

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.
