| 摘 要： | 通过在实验围隔中添加不同浓度的氮、磷等营养物质，对黄淮海平原低洼盐碱地鱼塘中的水质变化情况进行了初步研究，结果表明：1）围隔水体中异养细菌数量的变动，与水体中氮、磷等营养物质的浓度及比例密切相关，尤其是水体中磷的浓度对异养细菌数量的影响更为显著。2）围隔水体中的氮、磷等营养浓度及比率，明显地影响着其中藻类的数量和生物量。在实验条件下，水体中磷对藻类生长的影响要大于氮对藻类生长的影响，水体中N：P比为10：1左右是比较适宜藻类生长的比例。3）围隔水体中氮、磷等营养盐的去除能力与其中藻类的生物量及水体中N：P的比率密切相关，当围隔水体中的N：P比为10：1左右时，围隔水体中的藻类生长最好，生物量增加最快，相应地其对TN、TP的去除率也是最高的。

| Abstract: | The variance of water quality was studied by adding different concent ration of nitrogen and phosphorus into the tested enclosure.The results show that:(1)There existed strong relationship between the hetero trophic bacteria abundance and the concentration of ni trogen and phosphorus, especially the phosphorus.(2)The nitrogen and phosphorus concentration and ratio of N to P significantly affected the algae abundance and biomass.The suitable N:P value for algae grow th was 10:1.(3)There existed signif icant relationship between the ni trogen and phosphorus removing capacity and the algae biomass and the N:P value.When the N:P value was 10:1, the algae grew well and the biomasses were increased most quickly.In this case, the nitrogen and phosphorus removing capacity was the highest. |
