Abstract

The current study aimed to review the research trends on forest liming by age, country, and research topics, and seeks to summarize the effects of forest liming on soil, vegetation and water system in forest ecosystems. The recent goals of forest liming have been changed in response to changes in the acid deposition, and related studies have been mainly carried out in Europe and North America, where there is noted a massive forest decline, which was subsequently caused by acid rain. Most forest liming studies are noted to have focused on soil responses, however, the number of studies on the responses of vegetation and water system according to a literature review on the subject were relatively small. Meanwhile, forest liming influenced whole forest ecosystems through interaction between the soil, vegetation and water system as associated with the relevant regions. The changes in soil pH, base saturation, and cation exchange capacity by forest liming were noted as different depending on the soil layer and elapsed time after liming. The responses of vegetation to forest liming were shown in above- and below-ground plant growth and plant nutrient concentration, and also were noted to have varied depending on the available regional plant species and noted specific soil conditions. The chemical properties of the water system were changed similarly to those in the soil, leading to notable changes as seen in the planktons and available fish species in the region. Finally, these results could be used to plan further studies on forest liming, which would significantly benefit regional studies to promote the preservation of the species noted for protection in the region.

본 연구는 산림생태계에서의 석회 시용 연구를 연대별, 국가별 그리고 주제별로 경향을 파악하고 석회 시용이 산림생태계의 각 요소 (토양, 식생, 수계 등)에 미치는 영향을 종합 분석하고자 하였다. 산림 대상 석회 시용은 연대별 산성강하물 유입량의 변화에 따라 시용 목적이 달라졌으며, 관련 연구는 산성화로 인한 대규모 산림 피해가 발생한 유럽과 북미 지역에서 주로 수행되었다. 대부분의 석회 시용 연구는 토양 반응을 중심으로 수행되었고, 토양 이외에 식생, 수계 등을 포함한 연구의 수는 비교적 적었다. 한편 산림 대상 석회 시용의 효과는 토양, 식생 및 수계 사이의 유기적인 상호작용을 통해 산림생태계 전체에 미치며 특히 화학적 성질변화가 중요한 것으로 나타났다. 석회 시용 후 토양의 pH, BS, CEC 변화는 토양 층위와 경과 시간에 따라 다르게 나타났다. 그리고 식생의 반응은 지상부 및 지하부 생장과 식물체 내 양분 농도의 변화로 이어졌으며, 수종과 토양 조건에 따라 반응은 다르게 나타났다. 수계는 석회 시용 후 토양에서와 유사한 화학적 성질 변화를 보였으며, 이는 플랑크톤과 어류 등의 생물상 변화로 이어졌다. 본 연구 결과는 향후 석회 시용 관련 연구를 계획하는 단계에서 중요한 기초자료로 활용될 수 있을 것으로 기대된다.
