| 摘 要： | 利用室内培养实验比较研究了铵氮和硝氮对河北洋河水库微囊藻(Microcystissp.)生长、叶绿素a合成及产毒的影响.结果显示,铵氮培养条件下,在对数生长期,生物量及叶绿素a含量随铵氮浓度的升高而逐渐增多,但高铵氮浓度( 10.0 mg/L)培养条件则下降.藻细胞MCRR含量随铵氮浓度的升高呈波动变化,高铵氮浓度(1...

| Abstract: | In order to understand the interactions between environmental factors and the algal biomass in Lake Chaohu, those rela-tively important environmental factors to alga biomass were extracted.Based on monitored water quality data of Lake Chaohu in 2008, cluster analysis, discriminate analysis and the recognition of pollution feature were carried out to reveal the relationships be-tween water environment factors and algal biomass.Results suggest that the Lake Chaohu can be divided into severe polluted area, moderately polluted area, and mildly polluted area from west to east.The Chl.a and dissolved total nitrogen are the indicative fac-tors describing the significantly spatial difference in water environment.The sequence of pollution classification for all the monito-ring sites are as follows:Nanfei river inlake area >Shiwuli river inlake area >Tangxi river inlake area >West lake center area >Paihe river inlake area >Hangbu river inlake area >Zhongmiao area >Zhaohe river inlake area >Bakou area >East lake center area >Ship factory >Zhonghan town area.The screened important environmental factors to algal biomass vary with seasons.TP, TN, temperature, NO3--N and NH4+-N are closely related to algal biomass all the year round. |
