일반산주와 임업후계자 · 독림가의 산림 투자 인식을 비교분석한 결과 다음과 같이 임 · 독림가가 일반산주보다 산림투자에 대하여 상대적으로 높은 관심을 보이고 있었다. 1.일반현황의 비교에서 임 · 독림가가 일반산주보다 교육수준과 월평균소득 면에서 높게 나왔으며, 직업의 경우 임 · 독립가는 다양한 직종에 종사하고 있는 반면 일반산주는 농업에 편중되어 있는 것으로 나타났다. 2.산림의 소유동기에서 임 · 독림가의 경우 일부상속 · 일부매입이 41.2%로 가장 많은 반면, 일반산주의 경우는 선대로부터의 상속이 40.9%로 가장 많았다. 3.산림투자에 대한 산주태도에서 임 · 독림가가 일반산주보다 과거 5년동안 산림투자 경험과 정부지원 신청경험 모두 높게 나타났다. 4.정부지원 제도에 대한 인식에서 일반산주보다 임 · 독림가가 정부지원 제도에 대하여 상대적으로 많이 알고 있는 것으로 나타났으며, 정부지원 제도의 실행상태에 대해서는 임 · 독림가와 일반산주 모두 '그저 그렇다'는 미온적인 반응을 가장 많이 보였다. The study is focused on comparing the perception of forest investment by two types of forest owners, ordinary forest owners (OFOs) and forestry successors and model forest owners(FSMFOs). The results show that FSMFOs' perception of forest investment is relatively high compared with OFOs' perception The details are as follows ; 1.In the general status, the education and income levels of FSMFOs are higher than those of OFOs, and FSMFOs are engaged in various kinds of jobs while OFOs are inclined to lean toward farming. 2.Of the motives to own forests, partial-purchase and -inheritance is the most of FSMFOs(41.2% ) and inheritance the most of OFOs (40.9% ) 3.The number of FSMFOs who had made forest investment and applied government support is more than that of OFOs. 4.FSMFOs know government support better than OFOs do, while both show lukewarmness on weather the support is carried out according to the rules. Key words : forest investment, forestry successor, government support

본 연구는 우리나라 북부, 동부, 남부 낙엽송의 생장패턴을 파악하기 위하여 수행되었다. 각지역마다 15개의 낙엽송 영구고정표준지를 설치하였으며, 각 표준지마다 1개의 표준목을 벌채하여 모두 45그루의 낙엽송을 수간석해하였다. 수간석해 결과 연령은 19~60년생, 흉고직경은 17.0~47.9cm, 수고는 12.2~30.6 m, 수간재적은 0.1587~2.2792 ㎥의 범위를 보였다. 수간재적을 산림청의 재적과 비교해 본 결과 흉고직경 45 cm 이상의 재적에서 본 연구의 재적이 크게 나타났다. 연령에 따른 흉고직경 생장곡선과 수고생장곡선은 원점에 대하여 오목한 형태를 나타난 반면, 재적곡선은 원점에 대하여 다소 볼록한 형태를 띠는 것으로 나타났다. 흉고직경의 연년생장과 평균생장은 15년생일 때와 30년생일 때 각각 1.0 ㎝/yr과 0.7 ㎝/yr로 가장 높게 나타났다. 수고의 연년생장과 평균생장은 15년생과 25년생에서 0.6 m/yr와 0.5 m/yr로 가장 높았다. 한편, 재적의 경우 75년까지도 두 곡선이 만나지 않고 계속 증가하는 경향을 보였다. 흉고직경과 수고 및 재적의 생장률은 연령이 증가함에 따라 감소하는 경향을 보였으며, 특히 20~30년까지 급격히 감소하였다. 재적 성장률은 흉고직경과 수고생장률보다 월등히 높게 나타났다. The study was performed to find the growth pattern by stem analysis of Larch ( Larix kaempferi) in the Eastern, Northern and Southern Region of Korea. One standard tree from each of 45 sites was stemmed and analyzed for the study. The ages ranged in 19~60 years, dbhs in 17.0~47.9 cm, heights in 12.2~30.6 m, stem volumes in 0.1587~2.2792 ㎥. The stem volumes by our study had higher values over 45 ㎝dbh compared to Korea Forest Service. The dbh and height curves by age had a concave shape while volume curve had a convex shape. The average periodic annual increment (PAI) of dbh was the highest at age 15 (1.0㎝/yr) and the highest value of the mean annual increment (MAI) of dbh was 0.7 ㎝/yr at age 30. The highest values of PAI and MAI of height were 0.6 m/yr (age 15) and 0.5 m/year (age 25) respectively. The average PAI and MAI of volume continued to increase even after age 75. Growth percentages of dbh, height and volume tended to decrease with age and especially felled rapidly down at age 20~30. Volume growth percentage was much higher than diameter and height.

This study was carried out to establish the data base for forest management plan of DMZ region of Inje-gun and Yanggu-gun, Kangwon province through inventoring the forest resources of the region. A total of 138 temporary plots were installed to inventory and analyze forest type, dbh class and species distribution. The result showed that broad leaved forests ccurred the most at 91,3%, followed by mixed forests (5.8%) and coniferous forests (2.9%). mall dbh class trees (6 cm≤dbh≤18 cm) consisted of 83.5% of the total, middle dbh class(18cm≤dbh≤30 cm) 15.1% and large dbh class(dbh≥30 cm) 1.5%. In terms of growing stock per ha by forest type coniferous forest was the highest of 109.7 ㎥/㏊, followed by mixed forest (96.4 ㎥/ ㏊) and broad leaved forest (92.7 ㎥/㏊). This result consist with the fact that the proportion of middle dbhclass and large dbh class was coniferous>mixed>broad leaved. A total of 41 tree species appeared in the region and the top 10 species were Quercus mongolica, Fraxinus rhychophylla, Pinus densiflora, Acer ginnala, Robinia pseudoacacia, Betula schmidtii, Juglans mandshurica, Salix pseudolasiogyne, Ulmus davidiana, and Betula davurica, which account for 69.7% of the total.

Forest status, plantation investment environment, plantation plan and cost analysis were conducted of Republic of Fiji to provide the basic data for overseas plantation investment. The result showed that forest area of the country is 949,989ha of which plantation area is 14.6% and increased demand on industrial timber increased the plantation area. The climate and soil conditions were suitable for establishing short rotation coppice(SRC) especially of Gliricidia sepium. The capability of biomass supply was reached to 125,000 ton per year if Gliricidia sepium in the area of 5,000 ha is planted for maximizing biomass supply. Planting cost per hectare was calculated to be $385 which consists of forest land prepare($150/ha), sapling and cutting($50/ha), planting($150/ha), silviculture($20/ha) and protection and others($15/ha). Finally more detailed expectation of biomass growth and harvest through test plantation is required for plantation plan and tree species selection of the future.

The case study of the Cooperatives` members and Sincere Forest Managers/Forest Successors was carried out to find the determinants affecting the forest investment of private forest owners and analyze their effects on it. For this the landowners` forest investment probability function was estimated using the logistical regression model. The results showed that the forest investment of the Cooperatives` members was the function of forest area, stand age, forest income, and technical assistance. Three of the variables (forest income, forest area, and technical assistance) exhibited a positive effect on the forest investment as expected, while stand age showed a negative effect unlike the expectation of the study. In case of Sincere Forest Managers and Forest Successors forest area, distance(1)(distance from forest to road accessible by vehicle), knowledge of financing program, and forest income were significant indicators for the forest investment. All these variables showed the expected signs; forest area, knowledge of financing, and forest income had a positive effect on the forest investment, and distance(1) showed a negative effect.

This research aims to prepare policies for elderly housing, based on analysis of current status of elderly housing and demand for elderly housing. As provincial cities lack in terms of understanding elderly residence or housing, the research aims for policies targeting provincial cities, rather than existing policies mainly targeting for sizable cities. The result showed that between elderly and non-elderly age group in provincial cities, elderly age group had inferior living condition, but intention to move into public rental houses or silver towns was higher in non-elderly age group, and in analysis based on household attributes, one-person households had higher demand for elderly housing. The analysis showed interest on elderly housing is higher in non-elderly group, thus the needs for elderly housing should be considered to be more important in the coming years. Providing elderly housing in provincial cities must be focused on ways to provide low-floor housing within the central areas, considering housing types and city spaces, and needs for methods to provide public rental houses or silver towns is being raised. Moreover, ways to increase provision of ultimately lacking elderly welfare houses must be considered as an extremely important issue. Lastly, direct support methods for housing-related cost for the elderly age group were mainly about providing preservation of income and supporting maintenance cost.
