Abstract

This study was conducted to get some vegetation information and to find out a way to conseue the ecosystem in the Dongjin River. The riparian vegetation was investigated by Zurich-Montpellier school's method from June 2001 to March 2002. The number of riparian plants were 73 families, 188 genera, 238 species, 33 varieties or 272 Taxa in Dongjin River. The characteristics of life farm spectra were 97 therophytes (35.7%), 78 hydrophytes (28.7%), 41 hemicryptophytes (15.1%) 22 geophytes (8.1%), and 12 chamaephytes (4.4%). The riparian vegetation was identified 8 plant communities (Potamogeton brechtoldii, Hydrilla verticillata, Ceratophyllum demersum, Potamogeton malaianus, Phragmites japonica, Persicaria thunbergii, Cardamine scutata, Persicaria hydropiper) in upstream, 4 plant communities (Zizania latifoliar, Phragmites communis, Persicaria thunbergii, Humulus japonicus) in midstream and 8 plant communities (Hydrocharis dubia, Ceratophyllum demersum, Trapa japonica, Zizania latifolia, Paspalum distichum, Phragmites communis, Pericaria thunbergii, Amphicarpaea edgeworthii) in downstream of the Dongjin River.

동진강 일대의 인위적인 교란에 의한 하천식생의 복원 및 복구를 위한 기초적인 자료를 제공하고자 2001년 6월부터 2002년 3월까지 하천식생의 종 구성, 하천형태에 따른 군락의 구조, 현존식생의 분포 등을 종합적으로 분석한 결과는 다음과 같다. 동진강 유역에서 조사된 하천식생은 73과 188속 238종 33 변종 1품종으로 총 272종류가 조사 되었다. 또한 관속식물의 생활형에 따라 분류하면 침수식물이 23종, 부엽식물이 7종, 부유식물이 2종, 정수식물이 18종, 습생식물이 53종, 수변식물이 168종이었으며, 수생식물과 습생식물은 각각 50종과 53종류로 전체 조사된 272종류 중 37.9%를 차지하였다. 식물생활형의 분포비율은 휴면형 1년생 식물이 97종 35.7%, 수생식물이 78종 28.7%, 반지중식물이 41종 15.1%, 지중식물이 22종 8.1%, 지표식물이 12종 4.4%가 관찰되었다. 동진강 상류유역의 식물군락은 검정말군락, 검정말-실말군락, 붕어마름군락, 달뿌리풀군락, 고마리군락, 큰황새냉이군락, 여뀌군락 등 총 8개 식물군락이 분포하였다. 동진강 중류유역은 수생식물인 줄과 갈대군란 그리고 수변식물군락으로 고마리군락, 교란지식생인 환삼덩굴군락 등 총 4개 군락이 분포하였고, 동진강 하류 유역은 자라풀군락, 붕어마름군락, 마름군락, 줄군락, 갈대군락의 5개 습생식물군락과 털물참새피군락, 고마리군락의 2개 습생식물군락, 새콩 등의 나대지 식물군락 등 총 8개 식물군락이 관찰되었다.
