采用模糊综合评价法对内蒙古达里诺尔湖水质现状进行评价，利用2008年达里诺尔湖水质实际监测数据，确定了评价因子和各因子的权重，建立了评价因子的隶属函数和模糊矩阵，最后对达里诺尔湖水质现状进行综合评价。评价结果符合实际情况，说明模糊综合评价法用于达里诺尔湖水质评价的合理性和可靠性，并对控制湖泊水质污染提供了一定的理论依据。

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.
