任炳善 木浦大學校沿岸生物硏究所 1984 沿岸生物硏究 Vol.1 No.1
Physicochemical properties of saline soils with soil depty were determined in Samho-myun at March 1 in 1984. Soil pH was variable in upper layer of soil and relatively constant in lower part. Water content of soil showed the lowest value at surface soil and increased with soil depth. On the other hand, electric conductivity and sodium content decreased progressively with the increase of water content through soil. profile. Electric conductivity and sodium content of suface soil were 2 to times as high as those of subsoil. Concentration of available phosphorus was increased with soil depth due to it's leaching through soil profile. Total nitrohen of soils showed relatively side range of 0.6∼2.8㎎/g and were affected by vegetation of stand. Sodium content of surface soil was increased as function of distance from inland, but decreased near the site of the shoreline. Comparing physicochemical properties among stands, soil pH, water content, electric conductivity and concentration of sodium and available phorphorus were lower in salt marsh of Yongang-ri than in reclaimed lands of Sanho-ri and Nabuldo.

In this area, a liana e.g. Dioscorea tenuipes, Hedera rhombea, Lygodium japonicum, Akebia quinata, Vitis thunbergii, Dunbaria villosa, Trachelospermum asiaticum var. intermedium, Vitis amurensis, Paederia scandens, lives with Pinux thunbergii, Celtis aurantiaca, Mallotus japonicus and so forth in tree layer and subtree layer. There is artificial change no move in the researching sites, Acanthopanax chiixanensis will be transformed into Abies koreana - Acanthopanax chiisanensis community. Soil characteristics showed the high value such as pH 6.56 and conductivity 0.258mmho/cm in Acanthopanax koreanum community of Mt. Jiri, they also indicated digit as follows: the content of organic matter and total nitrogen are from 25.16 through 25.35% and 7.58 through 9.30mg/g respectably. The soil characteristics at Acanthopanax chiisanensis community in Mt. Jiri and Halla, was high as like pH 5.76, conductivity 0.238mmho/cm, total nitrogen 9.30mg/g, total phosphorus 0.126mg/g in Mt. Halla.

These studies had been carried out to investigate the characters of 4 streams as Gomakweon chon, Hampyeong chon, Sampo chon and Youngam chon and compared with the water quality in the downstream of Youngsan River at the period of Aug. 29 to 30 1996. The average paddy areas are 43%, forestry areas are 42.3% of down streams. Livestocks of cattle, hog and chicken are 42,160, 24,269 and 909,658 head. The amount of pollutant loading of BOD, SS, T-P and T-N in the Gomakweon chon is most higher as 15,240, 96,605, 1,350 and 2,565 kg/day, in the Sampo chon is most lower as 9,599, 36,160, 1,133 and 1,582 kg/day. Total amount of pollutant loading was lower in the Sampo chon which is a small area of the watershed, higher in the Gomakweon chon which is a large area of the watershed. To compared with water quality in the downstream of Youngsan River, the watershed areas of Gomakweon chon and Hampyeong chon are smiliar to as 216km and 200km, but water temperature, dissolved oxygen, conductivity, salinity, pH, turbidity, N-NH_3^-, N-NO_2^-, and N-NO_3^- of Gomakweon chon are appeared lower. To compared with Hampyeong chon and Youngam chon, N-NH_3^-, N-NO_2^-, N-NO_3^- and PO_4^- of Youngam chon was appeared 2-3 fold lower.

서울 남산과 강원도 백적산의 신갈나무 숲에서 엽록소 함량 및 광합성능의 비교
임병선,김종욱,이규송,이점숙,김준호,이창석 한국생태학회 2003 Journal of Ecology and Environment Vol.26 No.5
서울 남산과 강원도 백적산의 신갈나무 숲의 잎의 광합성 색소함량, 광합성능 및 증산율을 현장에서 측정하여 비교하였다. 서울 남산의 신갈나무의 광합성능, 광합성 색소함량 및 비엽면적이 강원도 백적산의 것보다 낮았다 신갈나무 잎의 광합성 색소함량은 6월초에 강원도 백적산보다 서울 남산이 많았으나 그 이후에 후자에서 적었고 두 지역 모두 시간이 경과함에 따라 감소하는 경향을 보였다. 8월 이후에 서울 남산의 신갈나무 잎의 일부에서 반점이 출현하였다. 비엽면적은 서울 남산의 것에서 작았다. 잎의 광합성능은 서울 남산에서 7∼9 월에 더 낮았다. To elucidate effects of air pollutants on ecophysiological properties of two Quercus mongolica stands at different levels of air pollution, photosynthetic capacity and chloroplast pigment were measured in leaves of Q. mongolica. Photosynthetic capacity, photosynthetic pigment content and SLA (specific leaf area) of Q. mongolica leaves in polluted area were lower than those in nonpolluted area. Also, the chlorosis and mottling in some of leaves were observed in polluted area after August. Except for total carotenoid (P<0.05) the correlations between photosynthetic capacity and pigment content were not significant. Photosynthetic capacity of Q. mongolica leaves in polluted area was decreased after July.

A model was developed to predict the effects of rising air temperature on net photosynthetic rateof Quercus mongolica stands at Mt. Paekcheok-san, Kangwon-do in South Korea. The PFD (Photon flux density) meteorological station and gas exchange or release responses of each tree component were measured. Using these data, we simulated the effects of increases in mean annual air temperatures above current conditions on annual CO2 budget of Q. mongolica stands. If mean annual air temperature is increased by 0.5, 1.0, 1.5, 2.0, 2.5 or 3.0℃, annual net photosynthetic rate will be increased by 8.8, 12.8, 14.5, 12.6, 9.2 and 1.0 ton CO2 ha-1 yr-1, respectively. Simulations indicate that changes in air temperature will have a major impact on gas exchange and release in Q. mongolica

The coastal vegetation was classified by the Braun-Blanquet's method and the standing biomass was investigated at the coastal areas of Sorido from June to November, 1999. The vegetation of the study areas were classified with 2 communities as follows: Carex boottiana community, Crepidiastrum lanceslatum community. Standing biomass was higher in Carex boottiana community(365 g.d.w/m2) than in Crepidiastrum lanceslatum community(102 g.d.w/m2)
