A total of 3 classes 2 subclasses 13 orders 45 families 64 genera and 118 species including saprophytic and ectomycorrhizal fungi was investigated. The mushroooms are classified into 17 families 32 genera and 80 species in Agaricales, 13 families 17 genera and 22 species in Aphllophorales, 2 families 2 genera and 2 species in Heterobasidiomycetes, 9 families 9 genera and 10 species inGasteromycetidae. There were edible mushroom of 46 species at Moonsu and Chungryang Mountain. The mushroom occurrence was closely related to vegetation and soil environmental conditions.

This study was carried out in order to produce useful material for the forest multiple use and forest protection by soil physico-chemical analysis of studied area in Mt. Palgong. The results of soil physico-chemical analysis and statistical analysis represented as following 2 points. 1. Soil depth was in the range of average 61.1 cm and soil texture was loamy sand and sandy loam except Donghwasa area. The part of solid phase and gaseous phase were higher than other areas, but liquid phase was less in verse. Soil water content was in an average 49.5%, penetrability was average 1.95×E^2cm/sec and the average of soil hardness was 1.64 Kg/㎠. This data showed that soil water content, penetrability and soil hardness were good at Mt. Palgong forest soils. 2. Soil pH was the range of 3.4 to 6.0, organic carbon content was 2.8% that is nearly mean of the Korea brown forest soils, total N content is somewhat smaller than that of other places, and total average C/N ratios was 13.9. Average available P_2O_5 concentration was 5.05 mg/kg that is lower than that of any others. The concentration of available P of coniferous forests is higher than that of deciduous forests. Exchangeable cations content is similar to those of the Korea brown forest soil and the order of the cation content extent is Ca^(2+) > Mg^(2+) > Na^+ > K^+.

This study was carried out in order to produce useful material for the forest multiple use and forest protection by physico-chemical soil analysis of studied area in Sokwang-ri Forest Genetic Resource Protection Forest which was divided into in standard plots include Tricholoma matsutake and Sarcodon aspratus production forest. The result of physico-chemical soil analysis represented as following. The soil type of T. matsutake production forest was Dry brown forest soil(B1), while on the other hand the soil type of S. aspratus production forest was Moderately moist brown forest soil(B3). Between T. matsutake and S. aspratus production forest did not result in significant changes in soil pH(5.22-5.60) and soil depth(47cm), but available phosphorus, carbon, and nitrogen contents were different results. CN ratio of the fairy ring of T. matsutake was quite lower than in S. aspratus production forests, which indicated that T. matsutake production forest was built up in the relatively immature soils which contain little organic matter. Generally, it was predicted that Pinus densiflora for. erecta forest succeeded to deciduous tree forest in stable soil environments. To conserve these T. matsutake and S. aspratus production forest, the contents of available phosphorous and exchangeable cation should be increased by continuous soil environment management and it should be established the secondary growth forests of old aged Pinus densiflora for erecta trees as soon as possible.

Assessment of the change of forest health of Backdu-daegan area in South Korea

허태철,박병배 한국산림과학회 2014 Forest Science And Technology Vol.10 No.4

The purpose of this study is to assess the change of forest health for a 5-year interval on paired seven coniferous anddeciduous forests at the Backdu-daegan region. Three criteria and 26 indicators covering from crown vitality to soilchemical properties were investigated in 2005 and 2010 at fixed permanent plots, which represent major types of forests atthese forest ecosystems. Growth of diameter at breast height in 2010 has increased by 16% for coniferous forests and 14%for deciduous forests compared to those in 2005. The crown vitality of both coniferous and deciduous forests showed nosignificant change. The sequential change of maximum species diversity index varied by region at the deciduous forests,but was consistent at coniferous forests. Organic content, total nitrogen, and available phosphate were significantlyincreased, but soil pH at both forest types was decreased, especially at the coniferous forests by 5.4 times. This studysuggests forest health, assessed by vegetation indicators, showed no change for the 5-year interval, but long-termmonitoring is needed to verify the influence of soil properties on tree crown vitality.

This study was carried out in order to produce useful material for the forest multiple use and forest protection management by soil physio-chemical analysis of studied area in Mt. Namsan. The result of soil physio-chemical analysis and statical analysis represented as following. In side of physical properties of forest soil in Mt. Namsan, Soil depth was average 31.4cm and available soil depth was average 20.0cm. Soil type was Brown forest soil that representative soil type in Korea. Soil texture was sandy loam(SL) except valley area. In side of chemical properties, the range of soil acidity was 4.29~5.19 (average 4.76), organic matter content was 3.17% that compared the lowest value to organic matter content of Korea forest soil. Available phosphorus was 3.64ppm that was lower than others forest soil. Exchangeable cation content was similar to the Korea brown forest soil. Cation exchange capacity(CEC) was 8.22 cmol_(c)/kg in Mt. Namsan.

The management of pine-mushroom forest means the environmental control for fairy ring of Tricholoma matsutake. Thus, the management demands intensive study for keeping healthy condition of the fairy ring, and that for the measurement of active portion of the soil ecosystem. This study was conducted to investigate the impact of T. matsutake fungus on the soil physicochemical properties and dehydrogenase activity by dividing the fairy ring into 3 regions such as `zone of decayed mycorrhizae`, `zone of physiologically active mycorrhizae`, and `in front of fairy ring` . The passing of T. matsutake did not result in significant changes in canon contents of soils, but available phosphorus, carbon, and nitrogen contents were different between the soils of active mycorrhizal zone and that in front of fairy ring. The dehydrogenase activity around the fairy ring of T. matsutake was quite lower than that in general forest soils, which indicated that the fairy ring of T. matsutake was built up in the relatively immature soils which contain little organic matter. Thus, the dehydrogenase activity of soil was thought to be used as an index for the management of pine-mushroom forest with considering that the management practically means the environmental control for keeping good conditions for the development of fairy ring of T. matsutake. Especially, the dehydrogenase activity measurement can be recommended as a tool for time-decision of litter removal by floor raking since the activity is a good index of litter decomposition.

The purpose of this study was to provide basic data for the cultivation of Allium victorialis var. platyphyllum in the area covered with forest vegetation. The populations of A. victorialis var. platyphyllum in Ulleungdo were naturally growing in the communities of Fagus japonica var. multinervis, Acer okamotoanum, Pinus parviflora, Tsuga sieboldii, Pinus densiflora, Pinus thunbergii, Tilia amurensis, and Alnus maximowiczii. On average, the study area of A. victorialis var. platyphyllum population was located in the places of 563 m above sea level, and in the slope area of 27.8°. Soil texture of its inhabitation site mainly consisted of sandy soil, sandy loam, loamy sand, and loam. The depth of the organic layer was 6 cm on average, soil pH 5.4, available phosphate content 18.5 ppm, and cation exchange capacity 18.6 cmolc/kg. The correlation between the site factors and soil factors by CCA analysis showed that the community of beech tree indicated positive correlation with carbon, nitrogen, sand content, and cation exchange capacity. 본 연구는 산마늘의 임간재배를 위한 기초 환경자료를 제공하고자 실시하였다. 울릉도 산마늘은 너도밤나무, 우산고로쇠나무, 섬잣나무, 솔송나무, 소나무, 곰솔, 섬피나무, 두메오리나무 군락에 자생하고 있으며, 입지환경은 평균 해발고도 563.4 m, 평균 경사는 27.8°이었다. 토성은 사토, 사질양토, 양질사토, 양토가 다양하게 나타났으며, 유기물층의 깊이는 평균 6 cm, 토양 pH는 5.40, 유효인산은 18.5 ppm, 양이온 치환용량은 18.6 cmolc/kg으로 나타났다.
