The purpose of this study is the practical application of landscape ecological indices to establishment of eco-village planning methodology. Planning an eco-village has to be carried out in the boundary of a small watershed that is defined by homogeneous ecological character. Because the small watershed is a landscape unit it can have unique ecological character. On this viewpoint, the spatial structure is analyzed by the ecological attributes of form, distribution arrangement and composition of the sub-landscape units. Among all of the sub-landscape units, a green tract of land is the main subject of the analyzing entity. Woodland or forest as a green tract of land is a source of biological species and materials. Therefore the ecological attributes of green patches are especially analyzed by landscape ecological indices. The selected landscape ecological indices are elongation, lobes, interior area ratio, convolution of perimeter and proximity of the green patches. These indices represent the state of ecological conditions and they will be the evaluation factors of the landscape ecological planning. These frameworks for landscape ecological planning apply to Obok and Ganggeum villages in Wanju-gun, Korea. A proposed planning was evaluated by the selected landscape ecological indices. Among the selected landscape ecological indices of green patches, perimeter convolution and proximity were increased. It means that the ecological condition of peen paches will be mon sound and green areas of the village will be expanded naturally. In addition to this connectivities among green patches will also be improved.

The purpose of this research is to evaluate five types of eco-village planning in order to introduce a landscape unit concept and theory in Korea. Although they had different backgrounds and motives of eco-villages planning, their common goal is to always maintain ecological planning and design in their villages. As concrete methods of ecological planning, we suggest three fundamental planning theories. 1. The boundary of a plan unit should be a watershed. 2. The survey and analysis of village ecotopes should be done in that defined watershed. 3. These results should be applied in the site and lot planning of eco-villages. These 3 steps should be done in a process and relevantly. In the evaluation of the five eco-village planning types, we found three results. 1. On a viewpoint of watershed, most planners recognized a watershed in survey and planning stages unconsciously. But they did not mention watersheds concretely and did not use this concept in the planning stage. 2. They did not define the concept of ecotope, but most planners recognized land-uses and vegetations of villages and vicinities as ecotopes. Also these could be proper ecotopes, but they did not use these compartment of ecotopes in the planning of ecosystem structure in villages. In addition, they did not deeply survey and analyze the ecotopes of villages and its vicinity. 3. On the viewpoint of sites and lots planning, they did not relevantly use the characteristics of watersheds and ecotopes in sites and lots planning. Therefore, they failed to implement the indigenous lots and subdivisions plan. In the size of lots and sites, they did not seriously consider the carrying capacity of ecosystem. We hope that our suggestion about the establishment of eco-villages planning is a fundamental theoretical framework of ecological planning in future eco-village planning.

산촌마을의 토지이용 패취 크기와 경계형태 특성에 관한 연구 - 전북 김제시 금산면 선동리 아직마을과 산수마을을 대상으로 -

A mountain village is defined as that which is autogenously formed over at least 100 years and supported by agricultural yields and forest products and forest area portion of which is over 70% in Guidelines for the Comprehensive Development Planning of Mountain Village. Recently, concerns about management planning of the Green and Eco-Village causes researches related to the Mountain Village's economics, tourism attractiveness, experience programming and investigation of the ecosystem and environment based on the village area. This kind of eco-village project should be supported by ecological evaluation of its spatial structure. But there is rare research of the village spatial structure studied from the ecological viewpoint originally. The purpose of this study is to interpret the spatial structure of Korean mountain village on the landscape ecological paradigm. The paradigm components are patches, corridors, networks, and matrix which explain the land and spatial structure at landscape scale. For this purpose, we selected two case study areas- Sansu and Ajick villages in Gimje city, Jeonlabukdo. We interpreted and evaluated the spatial structure by three steps: (1) to clarify the existing land mosaic pattern by land use mapping (2) to estimate the pore size as development area in matrix (3) to investigate the funnel effect of patch shape. These landscape ecological steps and frameworks could be applied for the proper methodology as fundamentals of eco-village planning and design. 우리나라 산촌마을의 경관구조를 경관생태학적 패러다임인 토지 모자이크 모형에 의해 해석하였다. 상대적으로 개발의 영향이 적게 작용하여 산림청의 산촌종합개발사업 대상마을로 선정된 전북 김제시 선동리 아직, 산수마을을 연구대상지로 선정하였다. 전형적으로 나타나는 마을유역의 면적(2.8∼2.0㎢), 마을구역 및 농경지의 면적율(27%), 숲의 면적율(73%)이 조사되었다. 패취 경계형태의 깔때기 효과 특성은 3차원적 지형요소와 풍수지리적 형국도를 원용하여 해석할 수 있었다. 패취 경계형태의 깔때기는 동물이동 주요 통로로 보며 하천에 의하여 형성되는 만입부는 물과 대기 흐름의 장소로 동시에 적용될 때 물질흐름이 해석될 수 있었고, 이러한 깔때기 효과의 개념은 풍수지리에서 사용되는 형국도에서 중심축과 지류축으로 나타나고 있었다. 이러한 내용은 산촌생태마을 계획. 설계 시 보전해야 할 숲의 적정 크기와 하천 및 능선의 녹지축 net-working을 하기 위한 기본적 틀로서 적용될 수 있다고 판단된다.

산란계의 분뇨 발생량과 이화학적 특성을 구명하기 위해 1일령 산란계 200수를 선별하여 공시하였으며, 200수 중 10수씩을 선별하여 분뇨의 채취에 이용하였다. 산란계의 일일 수당 평균 분뇨 발생량은 124.7±27.5 g/수/일이었으며, 계분의 수분함량은 76.7±1.9%, 건물 함량은 29.1±3.9 g/수/일이었다. 산란계 계분(55주령)의 N, P₂O? 및 K₂O는 각각 1.39±0.14, 0.62±0.11 및 0.68±0.09%이었다. 계분뇨의 pH는 8.19±0.71이었으며, BOD? 농도는 50,266±621 ㎎/L로 나타났다. COD<SUB>mn</SUB>의 경우 62,832±803 ㎎/L이었으며, SS는 121,725±16,165 ㎎/L를 나타냈다. 계분의 중금속 함량 중 Pb은 0.008±0.0012 ppm으로 규제 농도인 150 ppm보다 크게 낮았고, Cd의 경우 검출되지 않았으며, As는 0.008±0.0017 ppm으로 검출되었다. Hg은 0.003±0.0013 ppm이었으나, 규제 농도인 2 ppm에 미치지 못하였다. 따라서, 본 시험의 결과로 국내 산란계의 평균 분뇨 발생량을 추정할 수 있었으며, 분뇨의 이화학적 성상을 조사함으로써 유기비료원로서 적절한 사용이 가능할 것으로 생각된다. This work was conducted to investigate the manure excreta and chemical compositions of layers. Two hundred l-d-old ISA Brown layers were used in this work, and ten of 200 layers were selected for measurement of manure excreta with feeding phase. Means of the manure excreta per bird, the moisture content of poultry, and the dried manure were 124.7 ± 27.5 g/bird/day, 76.9 ± 1.9%, and 29.1 ± 3.9 g/bird/day, respectively. N, P₂O?, and K₂O of manure (55 weeks) were 1.39 ± 0.139, 0.62 ± 0.11 and 0.68 ± 0.09%, respectively. pH, BOD?, COD<SUB>Mn</SUB>, and suspended solids (SS) were 8.19 ± 0.71, 50,266 ± 621 ㎎/L, 62,832 ± 803 ㎎/L, and 121,725 ± 16,165 ㎎/L, respectively. Heavy metal contents in the manure were 0.003 ± 0.0013 ppm for Hg and 0.008 ± 0.0012 ppm for Pb, the latter of which was highly low compared with the standard (150 ppm), but no Cd was detected. The results of this work show the average excretion amounts and chemical compositions of layer's manure, which is used as an organic fertilizer.

본 연구는 옥수수 DDGS의 색상과 phytase 첨가가 회장 아미노산 소화율에 미치는 영향을 조사하기 위하여 실시하였다. 공시 재료는 세 가지 색상의 DDGS(DDGS1, DDGS2, DDGS3)를 이용하였으며, 시험계는 유사한 체중의 5주령 Ross종 (Ross 308) 육계 수컷 108수(평균 체중 1.8±0.2 ㎏)를 공시하였다. 시험 설계는 세 가지 색상의 DDGS와 phytase 첨가 3처리구(0, 500, 1,000 FTU/㎏)의 3×3 복합 요인으로 총 9처리구, 처리당 12수씩 완전 임의 배치하여 7일 동안 소화 시험을 실시하였다. DDGS의 색상은 각각 DDGS1이 L<SUP>*</SUP>=55.2, a<SUP>*</SUP>=8.8, b<SUP>*</SUP>=41.3, DDGS2가 L<SUP>*</SUP>=39.8, a<SUP>*</SUP>=7.5, b<SUP>*</SUP>=27.1, DDGS3이 L<SUP>*</SUP>=28.3, a<SUP>*</SUP>=6.1, b<SUP>*</SUP>=15.4로 나타났다. DDGS의 색상에 따른 아미노산 소화율은 어두운 색이 밝은 색보다 모든 아미노산의 소화율이 낮게 나타났다. DDGS의 처리구에 phytase를 첨가하여 급여시에 소화율이 증가하는 경향이었다. 필수 아미노산의 평균 소화율은 모든 처리구에서 각각 77.7, 80.0, 81.5, 76.0, 78.4, 80.1, 67.6, 69.6 및 71.0% 이었으며, 비필수 아미노산의 평균 소화율은 각각 73.6, 75.8, 77.3, 73.1, 75.3, 76.8, 67.4, 69.4 및 70.7% 이었다. 이번 실험의 결과에서, DDGS 색상이 어두울수록 그리고 phytase 수준이 낮을수록 아미노산 이용률이 낮게 나타났다. This work was carried out to investigate the effects of CDDGS (com distillers dried grains with solubles) colors and phytase levels on the amino acid digestibility of broilers for 7 days. One hundred eight Ross broilers were used in 9 treatment groups with a 3 × 3 factorial design as three colors of DDGSs (DDGS1, DDGS2, and DDGS3) in combination with phytase (0, 500, and 1,000 FTU/㎏). The L<SUP>*</SUP> values of DDGS1, DDGS2, and DDGS3 were 55.2, 39.8, and 28.3; the a<SUP>*</SUP> values, 8.8, 7.5, and 6.1; and the b<SUP>*</SUP> values, 41.3, 27.1, and 15.4, respectively. The ileal digestibility of amino acids was decreased as DDGS color was dark, and increased as additive phytase level was increased in the diet. Average digestibilities of essential amino acids were 67.6~80.0%, and those of nonessential amino acids 67.4~77.3. Amino acid digestibility was low in the dark DDGS with no phytase in the diet.
