공검지(경북 상주) 습지보호지역의 식물상

Abstract

생태계내 생물종 분포는 환경조건에 의해 결정되므로 종의 분포를 확인하는 것은 중요하다. 본 연구는 경상북도 상주에 있는 공검지를 대상으로 2012년 4월에서 10월까지 식물상을 조사하였다. 조사결과 관속식물은 69과 176속 204종 2아종 29변종 5품종으로 총 240분류군이었다. 이중 특산식물은 3분류군, 식물구계학적 특정식물종은 질경이택사, 물옥잠, 노랑어리연꽃 등 11분류군, 귀화식물은 26분류군으로 귀화율은 10.8%로 나타났다. 수생식물은 31분류군으로 한국 수생식물의 17.8%에 해당된다. 따라서, 습지보존을 위하여 불필요한 인간의 간섭을 최소화하고, 생태계의 변화에 대한 지속적인 모니터링을 통하여 효율적인 관리대책을 마련하는 방안이 요구된다. Knowing how many species live in a ecosystem is a major work because of the distributions of species are determined by the environmental condition. This study was carried out to investigate the distribution of vascular plants of Gonggeom-ji, located in Sangju-si, Gyeongsangbuk-do, from April to October on 2012. The vascular plants were summarized as 240 taxa including 69 families, 176 genus, 204 species, 2 subspecies, 29 varieties, and 5 forma. Among the investigated taxa, 3 taxa of Korean endemic plants were included. Based on the list of specially designated plants by Ministry of Environment, 11 taxa including Alisma orientale, Monochoria korsakowii and Nymphoides peltata were recorded. The naturalized plants were identified as 26 taxa and the ratio of naturalized index (NI) was 10.8% of vascular plants recorded. 31 taxa of hydrophytes showed 17.8% of Korea. To conservation of wetlands, we suggest that it is required to minimize for unnecessary disturbance of human and to make a strategy for effective management by continuous monitoring for ecosystem alteration.
