This study was conducted to clarify the characteristics of breeding bird communities between deciduous and coniferous forests from April to June 2005 in Mt. Namsan, Seoul, Korea. Two 10ha areas were selected for territory mapping of breeding bird communities. Number of breeding bird species, pairs,density and bird species diversity index were higher in deciduous forest with increasing amount of foliage in the forest profile or as forest structures developed compared with coniferous forest. The number of in coniferous forest. The differences in habitat structure between both study areas are very likely to have influenced how breeding birds used the available habitat. Forest structure and its interactions with birds should be consideration in forest management for birds and their habitat.

This study was conducted to identify characteristics of domestic pine forest soils and to elucidate major soil influencing factors for natural regeneration. We analyzed the physico-chemical characteristics of the soil samples collected from 23 pine forests and confirmed the similar results with the forest soil characteristics. Soil pH, organic matter content, total nitrogen, exchangeable Ca, silt content, and exchangeable Al were selected as the major soil factors among the exposed soils through 10 days of pine seedlings exposure and cultivation experiments and statistical analysis. Multiple regression analysis showed that soil pH had a positive effect on specific root length (SRL) of red pine seedlings and exchangeable Al was a significant factor affecting negative change in SRL. Taken together, the reduction of exchangeable Al by soil pH adjustment would be helpful for natural regeneration by restoring the forest and improving the fine root and root integrity of pine seedlings. Therefore, soil pH and exchangeable Al could be recommended as a major soil factor to be carefully considered in the monitoring and management of soil in pine forests that need to be renewed in the future.

Macroscopic and microscopic characteristics of Yellow-hearted pine and Red pine were investigated. Wood color, annual ring width and latewood percentage were observed by the naked eye. Anatomical properties as the structure of three sections and cell dimensions were examined by an optical microscopy. As a result, the color of bark in Yellow-hearted pine was Reddish-grey, and Red pine showed brown or gray. The color of heartwood and sapwood in Yellow-hearted pine was deep-yellow to brown and creamy-white. And the color of heartwood and sapwood in Red pine was light-brown and light-yellow. The annual ring width of Yellow-hearted pine was narrower than that of Red pine, and the latewood percentage of Yellow-hearted pine was a little higher than that of Red pine. There was no significant difference in the anatomical characteristics between Yellow-hearted pine and Red pine.

본 연구는 마을숲 연구에서 심도있게 다루어지지 않았던 해안 마을숲의 문화경관 특성을 파악하고, 그 가치와 정체성을 규명하고자 하였다. 경상남도 소재의 남해안 마을숲 10개소를 연구 대상으로 진행하였으며, 문헌연구, 현장조사, 인터뷰를 통해서 남해안 마을숲을 고찰하였다. 연구를 통하여 밝혀진 남해안 마을숲의 문화경관 특성은 문화적 특성, 실용적 특성, 경관적 특성으로 요약할 수 있다. 첫째, 내륙 마을숲이 유교적 배경이 강한데 비해 민촌에 조성된 해안 마을숲은 민간신앙의 영향이 두드러진 마을 공동체의 정신적 공간이다. 둘째, 남해안 마을숲은 해안마을이 접한 현실적 문제 해결과 경제적 효율을 우위에 둔 사고와 문화를 반영한 실용적 공간이다. 셋째, 남해안 마을숲은 단순히 수목으로 구성된 숲에 국한하는 것이 아니라, 주변 토지이용을 구성하는 바다부터 마을과 배후 산까지 광역적 범위에서 경관적 정체성이 이해되어야 한다. 본 연구는 그동안 주목받지 못했던 남해안 마을숲의 기초 자료를 구축하고, 내륙 마을숲과 차별화되는 해안 마을숲의 가치를 제고하였음에 의의를 지닌다. 나아가 동해안과 서해안 마을숲으로 연구의 대상을 확장함으로써 각 해안 마을숲의 특성과 차이점을 밝히는 연구가 후속되어야 할 것이다.

Because fire has significant impacts on fauna and flora in forest ecosystems, as well as socioeconomic influences to local community, it has been an important field of study for decades. One of the most common ways to reduce fire risk is to enhance fire-resilience of forest through fuel treatments including thinning and prescribed burning. Since fuel treatment can't be practiced over all forested areas, appropriate and effective strategies are needed. The present study aims to look at the relationship between spatial characteristics of forest structure measured with landscape pattern metrics and burn severity to provide guidelines for effective fuel treatments. Samchuck fire was selected for the study, and 232 grids covering the study areas were generated, and the grid size was 1km. The burn severity is measured with dNBR derived from satellite imagery, and spatial characteristics of forest structure were measured using FRAGSTATS for both landscape and class levels for each 1km grid. The results of this study strongly indicated that heterogeneity in composition and configuration of forests may significantly reduce burn severity. By enhancing heterogeneity of forests, fuel treatments for fire-resilience forest could be more effective.

The aim of this study was to investigate the comparative growth characteristics and ginenoside contents of wild-simulated ginseng on different years (7 and 13-year-old) by monitoring soil properties of cultivation regions. Plant and soil samples were collected from 6 different cultivation regions. Soil organic matter (OM), total nitrogen (TN) and cation exchangeable capacity (CEC) were significantly higher in 13-year-old wild-simulated ginseng cultivation regions compared to 7-year-old wild-simulated ginseng cultivation regions. Growth characteristics of wild-simulated ginseng had shown significantly higher in 13-year-old wild-simulated ginseng compared to 7-year-old wild-simulated ginseng. Ginsenoside G-Rb1, Rb2, Rc, Rd, Re, Rf, Rg1 were significantly higher in 13-year-old wild-simulated ginseng than 7-year-old wild-simulated ginseng. According to the results of correlation analysis, soil OM, TN and CEC of the cultivated regions were positively correlated with the growth of wild-simulated ginseng. In addition, the root length of wild-simulated ginseng showed positive correlation with ginsenoside content. Hence, this study was able to investigate the correlation between growth and ginsenoside content of wild-simulated ginseng based on soil characteristics of the cultivation regions.

시군구 단위 산림통계의 사회적 필요성에도 불구하고 자료의 부족으로 인하여 현실을 반영한 산림통계 산출이 어려운 상황에 있다. 따라서, 시군구 산림 통계 산출을 위하여 해당 시군구의 국가산림자원조사 자료와 주변 지역의 자료를 함께 활용하여 통계량의 오차 수준을 감소시키고 소면적 통계량이 해당 지역 산림의 지역적 특수성을 반영할 수 있는 새로운 소면적 통계산출 방법의 개발이 필요하다. 본 연구에서는 소면적 지역과 특성 구조가 유사하다는 가정을 만족하면서 통계산출을 위한 최소한의 표본점 개수를 확보하기에 적정한 공간 단위에 대한 연구를 수행하였다. 그리고 산림의 지역적 특성을 결정하는 주요 요인인 기후, 토양, 수종 구성 등의 동질성을 기준으로 구획된 확장시군구 기반의 합성추정법, 시 도 단위 자료를 이용하는 기본계획구 합성추정법, 인접 시군구 자료를 이용하는 이웃시군 합성추정법을 비교하고, 이 방법들을 통해 산출된 임목축적 통계의 지역적 특성 설명력과 상위 통계와의 관계에 대한 평가를 수행했다. 그 결과, 확장시군구 합성추정법이 기본계획구 합성추정과 이웃시군 합성추정보다 지역적 특성을 보다 잘 반영하는 통계를 산출하는 것으로 평가되었다. 또한 확장시군구 합성추정법을 통해 산출된 통계량은 시도 단위로 산출된 통계량의 95% 신뢰구간 내에 포함되었으며, 이웃시군 합성추정법에 의해 산출된 결과보다 시도단위 통계량과의 차이가 적게 발생하였다.

복분자딸기(Rubus coreanus Miq.)의 수관 층위별 광합성 특성과 잎 및 과실 특성을 조사하기 위하여 국립산림과학원 산림유잔자원부 구내에 조성된 복분자딸기 클론보존원에서 선발된 세 클론을 대상으로 각각의 특성을 조사하였다. 수관층위별 광합성 특성에서 광보상점은 상 중 하층이 각각 PPFD 33, 20, $5{\mu}mol\;m^{-2}S^{-1}$로 나타났으며, 층위별 광포화점은 상 중 하층이 각각 PPFD 1000, 500, $200{\mu}mol\;m^{-2}S^{-1}$ 에서 각각 8.52, 5.25, $3.60{\mu}mol\;CO_2\;m^{-2}S^{-1}$ 의 광합성 속도를 나타냈다. 클론별로는 덩굴형인 의령 7호가 상층에서 가장 우수한 광합성 능력을 보였으며 직립형인 송계 6호는 덩굴형의 두 클론과 비교해 하층에서 낮은 광합성 능력을 나타냈는데 이는 각 클론의 수형 특성에 따른 영향으로 사료된다. 층위별 엽록소 함량은 세 클론 모두 중층에서 가장 많은 양을 나타냈고 상층에서 가장 적은 엽록소 함량을 나타냈다. 잎의 특성에서는 층위가 높을수록 엽장, 엽폭, 정소엽길이, 정소엽폭 및 엽면적 항목이 낮은 값을 나타내 층위별 광합성 능력과 상반되는 경향을 보인 반면, 잎 특성의 단위면적당 건중량과 과실 특성의 종경, 횡경 및 입중 항목은 층위가 높을수록 큰 값을 나타내 층위별 광합성 능력과 유사한 경향을 나타냈으며 과실의 당도는 중층에서 가장 큰 값을 나타냈다.

This study attempts to analyze the relationship between forest volume and age based on 5th NFI data and spectral characteristics of satellite imagery using ASTER sensor in Korea. Forest stand volume and age had the negative correlation with the spectral reflectance in all of the band (Blue, Green, Red, SWIR). With increasing of stand volume and age, spectral reflectance decrease. The spectral reflectance of band1 showed the highest correlation between stand volume and spectral reflectance among the VNIR wavelength. The spectral reflectance band 1, 2 (visible wavelength) and stand age have high correlation compared to other bands. The correlation coefficients between forest volume and vegetation indices have low relationship. This result indicates that the reflectance of blue band may be important factor to improve the potential of optical remote sensing data to estimate forest volume and age.
