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.

$^{210}Pb$ 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. 산림유역의 토지이용 변화가 호수의 토사퇴적속도에 미치는 영향을 조사하기 위해 $^{210}Pb$ 연대측정을 수행하였다. 평상시 타코부호수는 쿠시로강으로 유출되지만 쿠시로강의 수위가 증가하면 역류현상으로 인해 쿠시로강에 유출된 다량의 세립토사가 호수로 유입되고 있어 호수 유출지점의 토사퇴적속도를 증가시키고 있었다. 그래서 호수에서 유출입하는 하천 주변의 토사퇴적물에서 $^{210}Pb$ 농도는 많은 양의 토사 퇴적의 영향으로 $^{210}Pb$ 농도가 희석되어 비교적 낮은 값을 나타내고 있었으며 지수함수적으로 감소하는 경향도 나타나지 않았다. 따라서 본 연구에서는 CRS 모델의 $^{210}Pb$ 연대측정법을 사용하였고, CRS 모델의 연대는 $^{137}Cs$ 연대(1963년)와 잘 일치하였다. 타코부호수에서 과거 100~150년 정도의 토사퇴적속도를 조사한 결과, 유역에서 인위적 개발이 없는 1880년대 이전 자연상태에서는 토사퇴적량이 $0.01{\sim}0.03g/cm^2/year$였고, 산림벌채와 하천공사가 시작된 1880년대~1940년대에는 $0.03{\sim}0.09g/cm^2/year$으로 토사퇴적이 증가하였다. 특히 유역에서 산림벌채, 하천공사, 농업개발과 임도 개설이 진행된 1980년대 이후에는 토사퇴적속도가 $0.09{\sim}0.84g/cm^2/year$로 자연상태보다 9~28배 증가하여 호수의 수심이 얕아지는 현상을 가속시키고 있는 것으로 나타났다.

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.

산림유역의 토지이용 변화가 호수의 토사퇴적속도에 미치는 영향을 조사하기 위해 210Pb 연대측정을 수행하였다. 평상시 타코부호수는 쿠시로강으로 유출되지만 쿠시로강의 수위가 증가하면 역류현상으로 인해 쿠시로강에 유출된 다량의 세립토사가 호수로 유입되고 있어 호수 유출지점의 토사퇴적속도를 증가시키고 있었다. 그래서 호수에서 유·출입하는 하천 주변의 토사퇴적물에서 210Pb 농도는 많은 양의 토사 퇴적의 영향으로 210Pb 농도가 희석되어 비교적 낮은 값을 나타내고 있었으며 지수함수적으로 감소하는 경향도 나타나지 않았다. 따라서 본 연구에서는 CRS모델의 210Pb 연대측정법을 사용하였고, CRS 모델의 연대는 137Cs 연대(1963년)와 잘 일치하였다. 타코부호수에서 과거 100~150년 정도의 토사퇴적속도를 조사한 결과, 유역에서 인위적 개발이 없는 1880년대 이전 자연상태에서는 토사퇴적량이 0.01~0.03 g/cm2/year였고, 산림벌채와 하천공사가 시작된 1880년대~1940년대에는 0.03~0.09 g/cm2/year으로 토사퇴적이 증가하였다. 특히 유역에서 산림벌채, 하천공사, 농업개발과 임도 개설이 진행된 1980년대 이후에는 토사퇴적속도가 0.09~0.84 g/cm2/year로 자연상태보다 9~28배 증가하여 호수의 수심이 얕아지는 현상을 가속시키고 있는 것으로 나타났다. 210Pb dating was conducted to examine the influence of land use changes in the forest catchment on lake sedimentation.

임산물생산조사 통계체계 개편에 관한 연구

안태성 ( Tae Seong Ahn ),안기완 ( Ki Wan An ),백을선 ( Eul Sun Baek ),최수임 ( Soo Im Choi ) 한국산림경제학회 2020 산림경제연구 Vol.27 No.2

임산물생산조사(production of forest products)는 조사대상 총 14종 147개 품목 중 10종 111품목에 대해서 매년 생산량과 금액을 전수조사 하고 있다. 그러나 생산품목이 많고 품목별 주산지가 다르기 때문에 전수조사를 통한 자료의 수집은 시간과 비용이 많이 소요될 뿐만 아니라 도급조사원의 전문성 결여 등 고품질 통계자료의 확보에도 한계가 있다. 따라서 전수조사 체계를 개선하기 위해서 현행 임산물생산조사의 자료수집 체계를 전반적으로 검토하여 현행 전수조사에서 표본조사 체계로 전환할 수 있는 품목을 선정하였다. 표본조사로 전환할 수 있는 품목은 품목별 생산량과 생산액 그리고 생산방법, 규모 등 몇 가지 기준을 검토하여 선정하였다. 그 결과 전국적인 규모로 생산되는 7개 품목에 대해서는 표본조사로 전환이 가능하고 지역적인 규모로 생산되는 총 18개 품목에 대해서는 향후 표본조사가 가능 할 것으로 판단된다. 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.
