Abstract
Through investigation and onitoring to urban landscape waters―Shichaqianhai and Roma Lake, water quality and habitat raits of typical landscape waters in Beijing were analyzed. The differences of transparency in wo lakes were discussed. The results show that, transparency of Shichaqianhai arrives at 70 cm, nd that of Roma Lake is 27 cm, which is because of different phosphorous concentration in two andscape waters. Therefore, phosphorous concentration is a key factor to keep aquatic ecosystem ealth in urban landscape waters.
