Abstract

The Saemangeum has a dry surface characteristic with a low moisture content ratio due to the saline and silt soil, so the vegetation cover is low compared to other areas. In areas with low vegetation cover, wind erosion has a high probability of scattering dust. If the vegetation cover is increased by cultivating crops that can withstand the Saemangeum reclaimed environment, scattering dust can be reduced by reducing the flow rate at the bottom. Thus, the purpose of this study is to analyze the effect of suppressing the generation of fine dust and scattering dust by cultivating winter forage crops on the Saemangeum reclaimed land. While growing 0.5 ha of barley and 0.5 ha of triticale in Saemangeum reclaimed land, the concentration of fine dust was monitored according to agricultural work and growth stage. Changes in the concentrations of PM-10, PM-2.5, and PM-1.0 were monitored on the leeward, the windward and centering on the crop field. As a result of monitoring, PM-1.0 had little effect on crop cultivation. the concentration of PM-10 and PM-2.5 increased according to tillage and harvesting, and tillage had a higher increasing the concentration of PM-10 and PM-2.5 than that of harvesting. According to the growth stage of crops, the effect of suppressing scattering dust was shown, and the effect of suppressing scattering dust was higher in the heading stage than in the seedling stage. So, it was found that there was an effect of suppressing scattering dust other than the effect of land covering. Through this study, it was possible to know about the generation and suppression effect of scattering dust according to crop cultivation.

새만금은 염분과 미사질 토양으로 인해 지표면이 건조하고 함수율이 낮아 다른 지역에 비해 식생피복이 낮다. 식생 피복도가 낮은 지역에서는 바람에 의한 침식으로 인해 먼지가 비산될 가능성이 높습니다. 새만금 간척지에서 견딜 수 있는 작물을 재배하여 식생 피복도를 높이면 바닥의 유속을 줄여 비산먼지를 줄일 수 있다. 따라서 본 연구의 목적은 새만금 간척지에 겨울철 동계 밭작물을 재배하여 미세먼지 및 비산먼지 발생을 억제하는 효과를 분석하는 것이다. 새만금 간척지에서 보리 0.5ha, 라이밀 0.5ha를 재배하는 동안 농작업 및 생육단계에 따라 미세먼지 농도를 모니터링하였다. PM-10, PM-2.5 및 PM-1.0 농도의 변화는 풍하측, 풍상측, 경작지 내부를 중심으로 모니터링하였다. 모니터링 결과 PM-1.0은 작물 재배에 거의 영향을 미치지 않는 것으로 나타났으며, PM-10과 PM-2.5의 농도는 경운과 수확에 따라 증가하였고 수확에 비해 경운 시 PM-10과 PM-2.5의 농도 증가가 더 높았다. 작물의 생육단계에 따라 비산먼지 억제효과를 보였으며, 유묘기보다 출수기에서 비산먼지 억제효과가 높게 나타났다. 따라서 토지피복효과 이외에 캐노피에 따른 비산먼지 억제효과가 있음을 알 수 있었다. 본 연구를 통해 작물재배에 따른 비산먼지 발생 및 억제 효과에 대해 알 수 있었다.
