Abstract

Topsoil including numerous soil seedbanks has been known to be a valuable material for ecological restoration. There is a lack of specific study for its utilization in the field of stream restoration. This study conducted a revaluation of the value of topsoil as a material for stream restoration. Furthermore, an ecological technique using topsoil was applied in an improvement project of a stream environment at the Hwanggujicheon Stream in Korea. Stockpiling and spreading topsoil was specifically applied to the revegetation of a low slope revetment and a high flow plain. The result of this application showed that topsoil played an integral role in eco-friendly restoration in terms of ecological, flood control, economic, and constructional aspects. In conclusion, this study's findings suggest that topsoil is a suitable candidate material for stream restoration.

다수의 매토종자를 함유하고 있는 표토는 중요한 생태복원 재료로서 많이 알려져 있으나, 이를 실제로 활용하는 구체적인 방법에 대한 자료는 부족한 실정이다. 본 연구에서 하천복원 재료로서 표토의 가치에 대해 재평가하였다. 또한 실제로 황구지천 하천환경정비사업에서 완경사 호안, 고수부 복원, 식재 등에 표토를 활용한 결과 생태적, 치수적, 경제적 및 시공적 측면에서 자연친화적 하천 복원에 매우 효과적이었다. 결론적으로 표토가 하천복원의 유용한 재료인 것을 확인하였다.
