通过1987年和1995年的实地调查，研究了琵琶湖南盆海岸沿着挺水植物带的近期变化。芦苇是大多数站点的优势种。与已发表的文献比较发现，挺水植物带的衰退大约从1981年开始。面积从1981年的62.6公顷减少到1995年的24.6公顷。这种迅速下降主要是由于沿着海岸线的堤坝破坏了栖息地。与水质变化和水位大幅度波动有关的其他环境压力被认为是造成下降的潜在原因。
Recent changes in the emergent macrophyte zone along the eastern shore of Lake Biwa's South Basin were investigated by field surveys in 1987 and 1995. Phragmites australis was the most dominant species at most sites. Comparison with the published literature revealed that the decline of emergent macrophyte zone had started since about 1981. The area had decreased from 62.6 ha in 1981, to 24.6 ha in 1995. This rapid decline was mainly caused by the destruction of habitats by an embankment along the shoreline. Other enviromental stresses associated with changes in water quality and large water level fluctuations were considered to be potential causes of the decline .
