초록

본 연구는 황폐계류 복원지의 식생변화에 대한 시계열 분석을 통하여 복원기법 및 효과에 대해 고찰하고자수행 되었으며, 수질정화습지와 월류보, 수생식물 복원지에서 복원 전, 후 식생변화를 2년간 모니터링 하였다. 복원1년 후 월류보에서 초본류 증가와 수질정화습지에서 줄풀의 피복도 증가가 조사되었다. 식생 피복률은 복원직후10~30% 감소되었고, 복원 1년 후 복원 전 수준으로 조사 되었다. 황폐계류 복원지의 식생변화는 복원 후 1년 경과시점부터 서식종수, 귀화률, 피복률이 증가하는 것으로 조사되었다.

영어초록

This study was conducted as a restoration research in a mountain stream of hydrologic cycle system,which is a type of microsites purposely changing vegetation. The status of vegetation in the three experimentalsites, water purification site, small dammed pole site, and aquatic plant restoration site, and one control sitewithin the area of the mountain forest stream were investigated in three different periods, namely before sitesrestoration, year of sites restoration, and year after sites restoration. After one year of restoration, number ofvegetation was increased in the small dammed pool and control site respectively. Vegetation coverage ratio ofZizania latifolia was increased at the water purification area. The effects of habitats restoration appeared to begood a year after the restoration of the experimental sites, in terms of families and species composition of theintroduced vegetation, and stream flow. Therefore, the results of the study strongly suggest that fairly effectiveways to restore and reproduce degrading mountain hydroecological habitats are by way of forming pool sitesand small dams in intermittent mountain streams and re-vegetating with selected plants.
