Abstract

Soil and micro-climatic environmental monitoring was conducted to evaluate the factors causing tree growth impediments at the Baekdudaegan ecological axis restoration project site. As a result, it was found that the nutrient supply was insufficient in the restoration project site due to the lack of organic matter, total nitrogen and cation exchange capacity of the soil compared to the surrounding forest. After the completion of the restoration, the soil moisture in the autumn decreased more than 7 times faster than that of the surrounding forest, and it was evaluated that the soil moisture was significantly low due to the lack of silt and clay content. In the case of the restoration site, the annual potential evapotranspiration was analyzed to be 975mm, which is approximately two times higher than that of the surrounding forest. The soil moisture of the restoration site in the summer decreased rapidly during the daytime when the amount of insolation increased and this was found to be strongly influenced by the increase in potential evapotranspiration. In order to improve the above factors affecting the tree growth at the Baekdudaegan ecological axis restoration project site, it is necessary to induce the smooth supply of nutrients and water to plants by improving physical proprieties and cation exchange capacity, i.e., using litterfall, humus soil, soil conditioner and organic fertilizer. The results of this study are expected to serve as basic data for the design, construction, and management of ecological axis restoration projects in the future.

본 연구는 백두대간 생태축 복원사업지에서의 수목 생육 장애 요인을 평가하기 위해서 토양 및 미기상 환경모니터링을 실시했다. 그 결과 복원 사업지에서는 주변 산림과 비교하여 토양의 유기물, 전질소 및 양이온치환용량이 부족하여 양분 공급이 결핍된 것으로 나타났다. 복원사업 준공 직후인 가을철 토양수분은 복원사업지가 주변 임내와 비교하여 7배 이상 빠르게 감소했으며, 미사질과 점토 함량 부족으로 인해 보습력이 매우 낮은 것으로 평가되었다. 복원 사업지의 경우 주변 임내와 비교하여 연간 잠재증발산량이 약 2배 높은 975mm로 분석되었다. 복원사업지의 여름철 토양 수분은 일사량이 증가하는 낮 시간대에 급격하게 감소하는데 이는 잠재증발산량 증가의 영향이 큰 것으로 나타났다. 이상의 수목 생육 장애 요인을 개선하기 위해서는 낙엽, 부엽토, 토양개량제, 유기질 비료 시비 등을 활용하여 보습력 증진 등 물리성 개량과 양이온치환능을 증가시켜 식물에게 원활한 양분 공급이 이루어질 수 있도록 유도해야할 것으로 판단된다. 본 연구의 결과는 향후 생태축 복원사업의 설계와 시공 및 관리방안 수립의 기초 자료가 될 수 있을 것으로 기대된다.
