하천 습지에서 생육하는 식물 군락의 분포와 생물과 비생물적 환경요인과의 관계를 분석하기 위해서 보성강내 하천습지에서 식물 군락과 환경요인을 조사하였다. 연구장소인 보성강 하천 습지는 화평습지, 반구정습지, 석곡습지로 구성되어 있다. 2022년 6월부터 9월까지 상관식생적 관점에서 식물군락 조사를 수행하였고 출현종의 피도는 Braun-Blanquet scale을 따랐다. 식물 군락 조사를 위한 방형구내에서 식물종과 각 종의 피도를 기록하였고 생물 요인으로 방형구 울폐도, 총 출현 종수, 외래종 수를 측정하였다. 비생물 요인으로는 고도, 방위, 경사도, 토성, litter 층 깊이, 우점종 흉고직경, 지형을 기록하였다. 총 50개의 방형구에서 버드나무와 달뿌리풀 군락이 가장 많이 발견되었고 Shannon 종다양도 지수가가장 큰 군락은 달뿌리풀-물피 군락이었다. DCCA에 의한 서열법 분석 결과, 하천제방, 제방사면, 상부고수부지권, 하부고수부지권, 고수변부, 수변부, 저수변부, 사주, 하중도, 개방수역 등 지형 요인에 의하여 가장 유의하게 군락이분리되었다. 하천 습지에서 보전되어야 하는 희귀식물로서 자라풀과 낙지다리는 저수변부에서 발견되어 털물참새피같은 생태계교란식물의 지형적 분포와 일치하여 저수변부의 하천 관리가 필요함이 밝혀졌다.
Abstract
To analyze the distribution of plant communities growing in river wetlands and the relationship between biotic and abiotic environmental factors, plant communities and environmental factors were investigated in river wetlands in the Boseong River. The Boseong River Wetland, the research site, consists of Hwapyeong Wetland, Bangujeong Wetland, and Seokgok Wetland. From June to September 2022, a plant community survey was conducted from the perspective of physiognomical vegetation, and the coverage of the emerging species followed the Braun-Blanquet scale. Plant species and the coverage of each species were recorded in the quadrant for plant community survey, and the cover of the quadrant, the total number of species, and the number of exotic species were measured as biological factors. As abiotic factors, altitude, orientation, inclination, soil texture, litter layer depth, dominant species diameter at breast height, and topography were recorded. In a total of 50 square plots, the most common Salix koreensis and Phragmites japonicus communities were found, and the community with the highest Shannon species diversity index was Phragmites japonicus-Echinochloa caudata community. As a result of ordination analysis by DCCA, the most significant clusters were separated according to topographic factors such as leeve, leeve slope, upper floodplain, lower floodplain, upper waterside, middle waterside, lower waterside, river island and opem water. As rare plants that need to be preserved in river wetlands, Hydrocharis dubia and Penthorum chinense were found in lower waterside, and it was found that the management of the river in the reservoir is necessary in line with the topographical distribution of ecosystem-disrupting plants, such as Paspalum distichum var. indutum.
