Abstract
Vegetation structure and distribution of the vascular hydrophytes and hygrophytes, and the growth pattern, standing crop and amounts of nutrient uptake by Salix species were investigated in the upper stream wetlands of the Namgang-Dam, Chinju-city, Gyeongsangnam-do, Korea from April to November in 1997. The flora was composed of 43 hydrophytes and 241 hygrophytes, or total 284 vascular plants. The life forms of the hydrophytes were classified as 27 kinds of emergent plants, 4 floating-leaved plants, 3 free-floating plants, and 9 submersed plants. In the herb layer, the dominant species was Persicaria hyciropiper, and the ranges of the species diversity indices (H'), equitabilities, (J') and community similarity indices (CCs) were 1.59~1.89, 0.87~0.96, and 0.35~0.83, respectively. In the shrub and subtree layers, 17 kinds of Salix species were supposed to the pioneer plants at the early stage of the succession. The number of branches per main stem of Salix species was 5.0. The DBH class-frequency histograms of Salix species were the reverse J type, and the natural regeneration of the Salix community was expected. Basal area of Salix species per square meter was
습지생태계의 변화를 예측하고 적절한 보호 대책을 강구하기 위하여 경남 진주시 남강댐 상류의 습지에서 1997년 4월부터 1997년 11월까지 수생 및 습생 관속식물의 분포 및 군락 구조와 버들류의 생장 유형, 현존량, 양분 흡수량 등을 조사하였다. 분포하는 수생식물은 정수식물 27 종류, 부엽식물 4 종류, 부수식물 3종류, 침수식물 9종류 등으로 43종류이고, 습생식물은 241종류였다. 초본층에서 우점종은 여뀌였으며, 종다양도는 1.59~1.89이고 균등도는 0.87~0.96으로 매우 높았으며 군집유사도 지수는 0.35~0.83이었다. 관목층 및 아교목층에 분포하는 버들류(Salix spp.)는 선버들을 포함한 17종으로서, 조사지역에서 천이 초기의 개척식물로 추정되었다. 버들류의 단위면적 (
