With 5 plants including Lindernia rotundifolia, Cryptocoryne crispatula, Hygrophila stricta, Microrium sp. and Peperomia sandersii as the tested materials and the highest eutrophic lake water from Guishui Lake in Yanqing County in Beijing City as the matrix of plant growth, 3 test groups with high, middle and low input density were set up to study the effect of input density of aquatic plants on the purifying efficiency of the eutrophic lake water.

方法］以小瓜子、缎带椒、中柳、皇冠和西瓜草5种植物为试材，以北京市延庆县妫水湖8月份富营养化程度最高的湖水为植物生长基质，设高、中、低3个投放密度试验组，研究植物投放密度对富营养化湖水的修复效率影响；通过测定水样中总磷酸盐、总氮、氨氮和硝态氮的浓度变化，确定植物修复的最佳效率。

When the TN:TP ratio was 25:1,V.spiralis had the best growth, with a biomass increment being 54% and 31% higher than that when the TN: TP ratio was 12.5:1 and 50:1, respectively, while the growth of periphyton, especially of epiphytic algae, was the worst, giving the least adverse effects on V. spiralis, indicating that a 25:1 of TN:TP ratio in eutrophic water was optimal for the growth of V. spiralis. However, such an optimal TN: TP ratio only worked when the nutrients concentration in eutrophic water was below the limited level, otherwise, it could be failed to be applicable.

结果表明：当TN/TP为25：1时，苦草的生长状态最好，苦草生物量的增长率最大，分别高于TN/TP为12.5：1和50：1时的54%和31%；当TN/TP为25：1时，附着生物尤其是附着藻类的生长状态最差，对苦草生长的不利影响最小；可见，富营养水体中适宜于苦草生长的TN/TP为25：1；TN/TP为25：1这一比例的应用具有相对性，当水体营养浓度低于限制水平时，该比例适用，如果水体中营养盐浓度超过限制水平时，该比例则不适用。
