This study examines the feasibility of establishing a Wood Industry Cluster in Jangheunggun, Jeollanamdo. The purpose of this study is to explore the right direction of Island areas lagging behind, and to provide policies for the Korea Forest Service to promote the wood industry. According to the results, it is necessary that eight individual projects, including the Forest Products Marketing Center, should establish the Wood Industry Cluster. The estimated cost for the total investment rates to 970 billion Korean won (KRW). In addition, the major economic effects created by establishing Wood Industry Cluster were estimated as well. The results show that the Wood Industry Cluster would gain a production inducement effect equivalent of KRW 1.9 trillion, an employment inducement effect amounting to 9,000 jobs, a value-added inducement effect of KRW 830.9 billion, and an indirect tax inductive effect of KWR 78.6 billion. In order for the Wood Industry Cluster to succeed, the study suggests on building a network that will bring industry, academy, research institute and authorities together, which will also help form the Organizing Committee for the wood industry. In addition the study provides a policy alternative for developing the Wood Industrial Valley in Eokbul-Mt, a Forest therapy cluster in Jeongnamjin LOHAS Town and a BIO-Food Industry Cluster in Jangheung.

This study examined the feasibility on the construction of a wood industrialization service center for a wood industry cluster establishment in Jeollanam-do. Construction of the wood industrialization service center is based on a discount rate of 3.5%, an investment period of 4 years, a business operations period of 16 years and an investment cost of 24600 million won; the total amount of the net present value, the cost-benefit ratio and the internal rate of return were assumed to be 2.579 million won, 2.51%, and 10.1%, respectively. In addition, the production inducement coefficient, the induced production effect, the income-induced coefficient, the income inducement effect, the employment inducement coefficient, and the employment inducement effect were estimated 1.4345, 35287 million won, 0.1655, 4000.7 million won, and 0.4665, 1,145 people, in the effects of the wood related industries using the multi-regional input-output model, respectively. Financial independence of operating income to cover its own costs incurred in accordance with the operating project might be practicable.

$^{210}Pb$ dating was conducted to examine the influence of land use changes in the forest catchment on lake sedimentation. The Kushiro River, into which Lake Takkobu drains under regular flow conditions, contributed to an increased sedimentation rate in sampling point at the lake outflow because turbid water from the Kushiro River flows back into Lake Takkobu during floods. The elevated sediment flux from the catchment dilutes the $^{210}Pb$ concentration in sampling points at the inflow of the Takkobu River and the lake outflow, which causes fluctuations in the $^{210}Pb$ concentrations in sediment cores. The $^{210}Pb$ dating was estimated using the CRS (Constant rate of Supply) model. The dates by the CRS model in Lake Takkobu profiles were in good agreement with the dates by $^{137}Cs$. Sedimentation rates reconstructed for the past 100-150 years suggested that sedimentation rates increased drastically following land use changes. While a natural sedimentation rate of $0.01-0.03g/cm^2/year$ is observed until the 1880s, whereas lake sedimentation accelerated to $0.03-0.09g/cm^2/year$ following land use changes such as deforestation and channelization, between the 1880s and 1940s. In particular, the sedimentation rates have been associated with deforestation, channelization, agricultural development and road construction, since the 1980s, and these rates were about 9-28 times higher than those under natural conditions, leading to accelerated lake shallowing.

Reduced water discharge and increased nutrient loads from forest catchments caused water quality degradation in downstream areas such as rivers, dams, wetlands and estuaries. In this study, hydrology and nutrient loading in the deciduous forest had been investigated over a year in order to conserve and manage the aquatic environment of coastal areas in Jeollanam Province. We quantified water discharge and nutrient (total nitrogen and total phosphorus) dynamics. The rainfall from June 28 to 29 (2008) in the deciduous forest catchment on Mt. Baekah resulted in a maximum water discharge (2.7 tons yr-1). The water flow responded quickly to the rainfall due to the steep slope. However, water discharge was low during the snowmelt period. The amount of annual precipitation was 12,519 ton ha-1 yr-1. Summer period (June-August) contributed the largest portion (7,270 ton ha-1) of the total annual precipitation compared to other seasons. The autumn period (September-November), which had a relatively low precipitation, showed the highest flow rate (84%) due to water retention in forest soil. However, the ratio of water discharge to precipitation during the summer period(consisted of heavy rainfall events) was lowest (47%) due to the flood control caused by water retention of the forest soil. The total nitrogen (TN) and total phosphorus (TP) annual input through precipitation were 1,412 kg yr-1 and 23.6 kg yr-1, respectively. Annual output of TN and TP was 198 kg yr-1 and 2.5 kg yr-1 in the deciduous forest catchment ecosystem, respectively. Based on annual nutrient input and output, the annual budget of TN and TP had been 14 kg ha-1 yr-1 and 0.3 kg ha-1 yr-1 in the deciduous forest catchment, respectively. In conclusion, TN and TP had been accumulated in the deciduous forest catchment ecosystem.

For production of forest products, the complete enumeration survey is annually performed for 10 categories, 111 items of 14 categories, 147 items in total. However, due to the large number of production items and different main production areas for each item, collecting data through the complete enumeration may be time-consuming and expensive, and there is a limit to securing high-quality statistical data because of lack of expertise of contracted enumerators, etc. Accordingly, in order to improve the complete enumeration system, the overall data collection system of the current forest products survey was reviewed to select the items that could be converted from the existing complete enumeration system to a sampling system. The items that can be converted into a sampling were selected by reviewing several criteria such as production quantity and production amount by item and production method and scale, etc. As a result, it is considered that 7 items produced on a national scale can be converted into a sampling, and a total of 18 items produced on a regional scale are expected to be sampled in the future.

This study was conducted to develop new forest resources model for Climate change. For this, it was performed to develop site index equations and estimate productive areas for Cryptomeria japonica of major species in the Southern area using environmental factors. The 67 environmental factors about Cryptomeria japonica, 626 sites were obtained form a Forest Site Digital Map and Automatic Weather System(AWS). It was regressed on site index equations. Eight environmental factors(A horizon soil color, B horizon soil color, March mean temperature, ridge-valley rate, country rock, August mean temperature, altitude above sea level, B horizon soil depth) were selected as independent variables, the result showed that the coefficients of determination were 0.466. The site index was ranged from 12 to 18. Compliance ratio about the site index more than 16 was showed 20.1%, and the area was calculated 225,263.8ha. Right land was valley about 600m below sea level in inland or area of low wind exposure.
