| 摘 要： | 目的]为水族箱的水质控制及增加水族箱的观赏性提供一些理论参考。方法]比较了沙质底质与无沙底质水族箱的pH值、氨氮等主要水质因子的变化趋势。结果]沙质底质和无沙底质水族箱pH值均先上升后下降，最后稳定在7．7左右，但无沙水族箱的变化幅度较大。无沙底质和沙质底质水族箱的氨氮含量都在9d后下降0．11mg／L左右，之后回升并稳定在0．15mg／L左右。无沙底质和沙质底质水族箱亚硝酸盐氮含量均先上升后下降，最后分别稳定在0．015和0．008mg／L左右。同期无沙底质水族箱的亚硝酸盐氮含量高于沙质底质水族箱，无沙底质水族箱的CODMn值大于沙质底质水族箱。3个水族箱的微藻总量都呈增长趋势，多样性指数无显著差异。结论]沙质底质水族箱环境因子的变化更平缓，其系统稳定性更强。

| Abstract: | Objective] The study aimed to provide some theoretical references for controlling the water-quality of aquarium and increasing its ornamental.Method] The change trends of main water-quality factors such as pH value,amino nitrogen in the aquaria with sandy sediment and no sand sediment were compared.Result] The pH values in the aquaria with sandy sediment and no sand sediment first increased and then decreased to stablize at around 7.7 finally,but the change range in the aquarium with no sand sediment was... |
