This study was tried to find out the applicability of decision support system for forest land use conversion, which developed based on algorithm for forest land-use conversion. Decision support system developed by Ministry of Safety Administration is free from the existing licensed laws omission. And it made the input requirements for each value of the final result so that you can determine whether the permit was available by the laws and regulations related to the algorithm for forest land use conversion. Also, in order to do field surveys, equal sampling interval method is used to extract samples for the operability by comparing and analyzing the actual area. As a result, 88 areas of total 100 areas are able to get permission by the decision support system for forest land use conversion, and it means if there is enough data with sufficient research, it can make the availability permits easily.

DMZ has a lot of natural resources. Also there is very important position as a ecological and geographical. Meanwhile, development schemes and plans were established but that was development to only simple plan such as a tourism and income without communication with local residents. This study was tried to exhibit increasing income of residents in DMZ area using FGI (Focus Group Interview) and SWOT analysis. First of all, analyzed the status of forest resources and carried out a Focus Group Interview targeting residents who live in around DMZ, and then suggest an alternative to increasing income and regional development in Yanggu-gun by SWOT strategies. As a result, realistic plan for achieving regional development is deregulation of the laws related to forest land use conversion for the forest product in DMZ area. Military experts and forest experts have to inspect the area for considering the practical application of the regulation in protected areas directly. National or local government has to effort pursuing future business for regional development through the communication with residents in DMZ area.

본 연구는 산림경관에 대한 관심과 중요도가 증가함에 따라 체계적인 보존 형성 관리를 위한 정책적 시사점을 찾기 위하여 현장에서 관리주체가 되는 지자체 관리자를 대상으로 산림경관에 대한 인식, 경관관리 현황, 경관관리를 위한 중요도-만족도 분석을 실시하였다. 조사결과 응답한 105명의 지자체 관리자들은 산림경관의 중요성을 인식하고 체계적인 관리를 위한 산림경관계획 수립의 필요성을 인지하고 있었지만 이를 뒷받침할 수 있는 경관관련 각종 정보 및 제도적 장치가 미흡한 것으로 나타났다. 또한 중요도-성취도 분석을 통해 '지속유지' 속성 4개, '노력 집중화 지향' 속성 4개, '낮은 우선순위' 속성 3개, '과잉노력 지양' 속성 4개가 도출되었다. 이러한 연구결과를 바탕으로 체계적인 경관관리 방향이 설정되어야 할 것으로 판단되었다.

본 연구는 확률밀도함수를 이용한 목재수확예측기법으로 면적가중치법(AW), 면적비율가중치법(ARW), 표본면적변화율가중치법(SCRW)를 적용하여 전국 국유림의 산림경영계획 목표량 설정을 위한 벌채계획량을 추정하였다. 벌채계획량 추정을 위한 산림면적은 산림기본통계의 2010년, 2015년의 영급별 국유림면적을 이용하였으며, 5년간의 산림면적변화량을 벌채면적으로 가정하여 산출하였다. AW, ARW, SCRW를 이용한 벌기령의 평균은 각각 5.41, 5.56, 5.37로 V~VI영급수준으로 산출되었다. 벌채면적은 각각 594,462 ha, 586,704 ha, 580,852 ha로 SCRW가 실제 면적변화량과 가장 유사하였으며, Chi-square 검정도 SCRW이 가장 안정적으로 분석되었다. 산림경영계획의 목재수확예측을 위한 방법으로 SCRW가 AW와 ARW보다 적합한 것으로 판단된다.

This study was carried out to review the pattern of forest stand development for six Gangwondo Baekdudaegan Mountains which experienced different type and duration of intensive legal protection. Vegetation data from point sampling method were employed to classify community types by cluster analysis on the basis of the importance values of canopy tree species for the study areas. The names of classified communities were given by the composition of dominant tree species. The communities were also compared one another in terms of stand structure by species diversity index. The results indicated that National Parks (Seoraksan and Odaesan) had greater proportion of mixed mesophytic forest type which was supposed to progress further forest succession process so as to have more complex and diversified stand structure. On the other hand, ordinary forest areas (Seokbyeongsan and Deokhangsan) had greater proportion of the forest types which was dominatively composed of Quercus mongolica and Pinus densiflora. The forest types with large amount of these two species would tend to develop for relatively short period of time of 40-50 years after artificial disturbances. Hyangnobong of Natural Protection Area and Hambaeksan of Natural Ecosystem Conservation Area showed intermediate stand development pattern in between National Parks and ordinary forest areas. The period of intensive legal protection of the forest area was positively correlated with species diversity index (R=0.736), and noted that the forest which received intensive protection regulation for longer period tended to show more complex and diversified stand structure.

본 연구는 일본잎갈나무 임분의 안정성을 고려한 임분밀도 관리의 적정 수준을 탐색하기 위해 수행하였다. 분석에 활용된 조사 표본점 259개소의 자료를 통해 임분밀도관리도를 개발하였고, 이를 이용하여 상대수확량지수(Relative yield index: Ry)와 형상비(Height-to-diameter ratio: H/D)간의 관계 구명을 통해 임분밀도 관리의 적정 수준을 찾고자 하였다. 추정된 임분밀도관리도의 설명력(R²)은 0.600으로 나타났다. 상대수확량지수와 세장목의 출현비율의 관계 분석 결과, 일정임분밀도 이상에 도달할 경우 세장목의 비율이 급격히 증가하였고, 해당 곡선에서의 상대수확량지수(Ry)의 임계값은 0.63으로 분석되었다. 본 연구의 결과는 풍해, 설해와 같은 자연적인 피해를 저감 할 수 있는 임분 관리 전략 수립과 경제림의 생산력 향상을 위한 임분 시업체계 개발에 기여할 것으로 사료된다.

This study designed a model of the efficient production schemes and raw materials transportation optimization of current South Korean's simple and monolithic distribution system of wood to build a SCM (supply chain management) as a basic level to establish a distribution of future by pellet production of raw materials costs and reduce transport costs, and specifically to forest of pallet to contribute to revitalizing the market. The result of each transportation costs after building the best transportation network from raw material supply area to demand area applying transport law was 964,600 thousands Won from 6 supply areas to 7 demand areas. And the result of each model's analysis to get the pellet's efficient production through production cost reduction showed that it reduced from 325,701 Won/t to 240,106 Won/t, results of existing efficient pellet for the production model 8,233 tons over 20,000 tons annual production capacity from the size of the expanded production capacity when the expansion. However, when the production size expanded to 50,000 Tons of the production, the effect was very small even though production cost decreased.

This study compared with the object of designation and the management practices for Protection Forests between Korea and Japan to establish the management and development directions of Korea's Protection Forest. 1. Water conservation forest from total areas of Protection Forests occupied 90.6 % in Korea and 68.4 % in Japan, respectively. The water conservation forest was the most important function among the Protection Forest's functions in both countries. 2. The 10 million ha of Protection Forest in Japan increased for last 100 years. The 100 thousand ha per year was designated as Protection Forest. In contrast, The 655,535 ha of Protection Forest in Korea decreased for last 42 years with decreasing of 15,000 ha per year. 3. In Japan, Protection Forest can be managed by forest silvicultural practices such as forest harvest, thinning, and pruning to recover and improve the Protection Forest's functions. 4. In case of Korea, it is necessary to a mid- or long-term counter plan to increase the area of Protection Forest by the government, and needs to the recovery and improvement of Protection Forest's functions.

This study was conducted to clarified the relationship between bird community and forest structure and present the counterplan for protection and management of bird community from February 1993 to July 1995 at deciduous and coniferous forest within Mt. Nam area, Seoul, Korea. DBH distribution has not significant differences in each study site. Deciduous forest had more foliage coverage in all layers than coniferous forest. Total 41 species of birds, which were 16 species of resident, 14 species of summer visitor, 4 species of winter visitor, and 7 species of passage migrant were recrded in two study sites. Leaf use rate of birds was increased the increase of coverage. The number of breeding species and pairs, breeding density, and diversity index were greater in deciduous forest than coniferous forest. The number of species and pairs on bush-nesting and foraging guild were greater than other guilds. And the nuber of species and pairs on hole nesting guild were the fewest in nesting guild. Use rate of artificial nests for improvement of habitat quality was greater in coniferous forest than deciduous forest. Maintenance of bush layer, increase of coverage and leaf layer diversity, supply of artificial nests, management of large trees, and control of natural enemy were necessary for protection and management of bird community in Mt. nam area.
