| 摘 要： | 通过室内试验探讨中华圆田螺营养盐释放的温度影响因子对氮磷营养盐循环、水体悬浮物以及摄入量和排泄量的影响等生态特性。研究发现,温度对中华圆田螺营养盐的释放有显著影响。TN和TDN随温度升高呈小幅度增加,TP和TDP则随温度升高呈明显增高,当温度分别由8℃升高至15℃和35℃时,TN则分别增加了5.71%和23.43%,TDN增加6.76%和17.57%;TP则增加92.60%和208.35%,TDP增加2.25%和110.17%。当温度分别由8℃升高至15℃和35℃时,NH4+-N分别增加了1.89%和26.55%,PO4--P增加了14.27%和225.96%,NO3--N则不受温度影响。另外,温度对SS的影响不明显(p>0.05),即使在8℃条件下仍有较高的去除率,为69.50%;试验各个温度下,螺对SS摄食量都大于排泄量,随着时间延长,螺对SS的摄入量有所降低,但仍高于其排泄量。由此可见,底栖软体动物对富营养化水体具有明显的净化作用,为湖泊富营养化控制提供了可供参考的依据。

| Abstract: | To study the temperature factor affecting nutrient release of Cipangopludina chinensis,laboratory simulation experiments were carried out,and other traits of Cipangopludina chinensis,such as the effects of nitrogen cycling,phosph orus cycling,suspended substance in water column,food intake and output in the system were also investigated.Results showed that temperature had great influence on nutrient release of Cipangopaludina chinensis.The release rate of total nitrogen and dissolved nitrogen increased,but ... |
