하구습지는 독특한 기수역이 형성되며 이러한 환경에 적응하여 살아가는 생물에게 중요한 서식처로 기능을 수행한다. 그러나 과도한 개발과 이용에 따른 인위적 간섭으로 하구습지 고유의 기능 및 특성을 변화시킨다. 본 연구는 생태계가 우수한 하구습지 보전을 위한 기초자료를 수집하기 위해서, 태화강하구습지를 대상으로 식생 분포 특성 및 생물상 현황을 조사하였다. 연목림 식생, 정수 및 유수역 다년생 초본식생, 부유·침수식생 등 6개 상관식생형의 25개 식물군락이 확인되었다. 지형다양성이 높은 상류부에서 다양한 유형의 습지식생이 분포하고 있었다. 생물종 다양성은 멸종위기 야생생물 7종 포함 총 696종이 확인되었다. 생태적 연결성이 양호하여 감조하천이 형성되는 구간을 중심으로 다양한 기능군을 가지는 기수성 생물종이 분포하며, 하천 구간별 수환경에 따라서 잠수 및 수면성오리류 등 다양한 수조류의 서식을 확인하였다. 태화강하구습지의 생태정보의 수집은 하구 생태계의 보전·관리 기반을 마련하고 정책 수립을 지원하는 데 기초자료로 활용될 수 있을 것이다.

Abstract ▼ AI-Helper

Estuarine wetlands, which form a distinctive brackish water zone, serve as important habitats for organisms that have adapted to and thrive in this environment. Nonetheless, excessive development and utilization result in artificial disruptions that alter the distinctive functions and attributes of estuarine wetlands. To collect the basic data for the conservation of estuarine wetlands with excellent ecosystems, we investigated the vegetation distribution characteristics and biota status of the Taehwagang River Estuarine Wetland. Data from vegetation surveys have shown that 25 plant communities of six physiognomic vegetation types, including willow vegetation, lotic and lentic herbaceous vegetation, floating/submerged vegetation. In the upper reaches, where topographical diversity was high, various types of wetland vegetation were distributed. In terms of biodiversity, a total of 696 species, including 7 endangered wildlife species, were identified. Due to good ecological connectivity, tidal rivers are formed, brackish water species including various functional groups are distributed around this section. The inhabitation of various water birds, such as diving and dabbler ducks, were confirmed according to the aquatic environment of each river section. The collection of ecological information of the Taehwagang River Estuarine Wetland can be used as a framework for establishing the basis for conservation and management of the estuarine ecosystem and support policy establishment.
