  • This study was conducted to supply basic data for restoration and management of forests in Civilian Control Zone, with surveying naturalized plants around abandoned military camps. The total study sites are 72 abandoned military camps, from Gosung in east region to Paju in west region of Civilian Control Zone. The naturalized index of total area is 12.6%, and naturalized index of east and middle regions are 12.1% and 8.4%. But its index of west region is 15.9%. These results are due to geographical characteristics. The east and middle regions are in steep mountainous districts, and so but west region is flat district, and so naturalized plants was imported by only army. But west region is in flat districts, and so imported method of naturalized plants is very various. The main naturalized plants are Ambrosia trifida and Ambrosia artemisiifolia var. elatior in Civilian Control Zone. The main dispersion pattern of naturalized plants are gravity dispersion pattern ($D_4$) and wind and water dispersion pattern ($D_1$). The all naturalized plants are photophilic plants in survey sites. And so, if abandoned military camps are recovered to forests, the naturalized plants are disappeared because of the change of sunlight condition. So it is necessary to manage and recover forests, even if that area is Civilian Control Zone.

  • 2007년에 잣나무림에서 하늘소과, 바구미과, 나무좀아과에 속하는 천공성 딱정벌레 군집을 말레이즈 트랩을 활용하여 조사하였다. 하늘소류 15종 184 개체, 바구미류 17종 185개체, 6종 1,246개체의 총 1,615개체 천공성 딱정벌레가 채집되었고 우점종은 왕녹나무좀이었다. 개체수에 따라 순위를 매겼을 때, 잣나무림에서 천공성 해충과 나무좀류 군집은 나무좀아과의 한 종에 의해 우점되어 생물다양성이 낮은 것으로 나타났다. 잣나무림에서 간벌은 나무좀과 암브로시아좀류의 풍부도에 영향을 미쳐 특정 임분에서의 개체군들은 간벌 1년 후 밀도가 증가했으나 그 후 감소하였다.

  • 돼지풀 잎에서 검정된 monoterpenoids는 약 29종이었고, 그 가운데 octene, $\alpha$-ponene, $\beta$-myrcene, 1.3.6-octatrine, endo-borneol, (-)-bomyl acetate의 함량이 높다. Monoterenoids 총 함량은 초봄부터 점차 증가하여 7월에 가장 높았고 그후 감소하였다. 돼지풀 잎에 함유된 휘발성물질은 수용체 유식물의 뿌리와 줄기 생장에 억제효과를 나타내었으며, 생엽량의 증가에 따라 억제효과도 증가하였다. 이에 따른 억제효과 차이의 유의성은 대부분이 P<0.05 수준이었다. 억제효과는 처리식물에 따라 큰 차이가 있었다. 돼지풀 생엽의 채취시기에 따른 유식물 생장 억제효과의 경향성은 대부분의 처리식물에서 7월>6월$\geq$5월 순 이었다.

  • 돼지풀의 수용추출액에 함유된 화학물질중 benzoic acids와 phenolic compounds가 주를 이루었고 일부 non-acids 화학물질도 검출되었다. 또한 수용추출액에 함유된 화학물질은 부위에 따라 차이를 나타내었으며, 잎에서 60종류, 뿌리에서도 53종류의 물질이 검출되었다. 총 함량은 잎이 0.48 mg/g.f,w, 뿌리가 0.37 mg/g.f,w이었다. 수용추출액은 수용체식물 종자발아와 유식물 생장에 뚜렷한 억제효과를 나타내었고, 식물 종에 따라 큰 차이를 보였다. 추출액의 농도가 증가됨에 따라 억제효과도 증가하였다. 발아와 유식물 생장에 억제효과가 높은 식물은 고추, 상치, 쇠무릎 등이었고, 배추와 무는 비교적 낮은 억제 효과를 보였다. 종자발아 및 유식물 생장 실험 모두에서 잎 수용추출액의 억제효과가 뿌리보다 높게 조사되었다.

  • In this study vegetation structure was monitored focusing on slanting surface of stream for the purpose of developing a management plan and ecological restoration of small stream in Paju. The study was conducted by types of geographical structure, yearly flora, naturalization rate changes, actual vegetation changes, plant community changes. Slope area of small stream in Paju was varied in the slope range of $10{\sim}35^{\circ}$. The survey results of yearly flora showed that 37 species appeared in 2000, 55 species in 2001, 95 species in 2002, and 125 species in 2003. Therefore, the trend of continuous increase of flora each year was observed. In the case of yearly changes of actual vegetation, indigenous wetland herb community including Phragmites communis$(19.99%{\rightarrow}18.42%{\rightarrow}19.60%)$ did not show substantial changes in the area, while the influence of controlled flora such as Humulus scandens$(8.86%{\rightarrow}5.26%{\rightarrow}9.73%)$, and Ambrosia artemisiifolia$(1.06%{\rightarrow}1.43%{\rightarrow}6.93%)$ were increased. The vegetation structure investigated by 18 preset belt-transects also indicated that Phragmites communis and Miscanthus sacchariflorus were maintaining the status or decreasing the population, while the population of Humulus scandens, Ambrosia artemisiifolia, Setaria viridis, and Erigeron canadensis were greatly increased. Our proposal management to restore ecology is as follows: first, preservation and restoration of Phragmites communis landscape; second, restoration of potential stream vegetation community; third, selection and removal of controlled plants.

  • To determine the peak dispersal times of allergenic pollen grains in Ulsan, Korea, we performed continuous airborne pollen counts at three stations (Sts. A, B, and C) in Ulsan from August 2009 to November 2010. Pollen grains were sampled using a Durham sampler. Two peak pollen dispersal seasons were observed per year. The peak seasons generally coincided with the flowering period of anemophilous trees: Taxodiaceae (February), Alnus (March), Cupressaceae (April), Quercus, and Pinus (May), and with the flowering phase of herbs from August to November, e.g., Humulus, Artemisia, Gramineae, and Ambrosia from August through September. The highest concentration of airborne pollen was from Pinus (68%), followed by Quercus (15%), Alnus (6%), and Humulus (2%); whereas very low pollen concentrations were from Taxodiaceae, Cupressaceae, Artemisia, Gramineae, and Ambrosia (${\leq}$ 1% of the annual total airborne pollen concentration). Our findings indicate that Alnus and Humulus pollen are major allergens whereas those of Pinus and Quercus are minor allergens. The concentration of Alnus pollen grains at St. C was over five times that at Sts. A and B. This finding implies that individuals living at or near St. C are exposed to high concentrations of Alnus pollen before and after March, which is the flowering period of the alder tree. From August to September, individuals living at or near St. B are exposed to high concentrations of Humulus pollen. Our study suggests that Alnus pollen may be the major aeroallergen causing pollinosis in the spring at St. C and Humulus pollen may be the major aeroallergen in autumn at St. B.
