| 摘 要： | 主要探讨城市化对城市内河蓝藻复苏和生长的影响。这些影响包括河流中营养物的升高、高等水生植物的灭绝、河水所受光照强度的变化以及由河水滞流带来的水体复氧效率降低对内河中蓝藻爆发条件的影响。通过实验我们发现金鱼藻与水网藻的存在可以在一定程度上抑制蓝藻的生长,金鱼藻的效果比水网藻更明显。适宜的光照是蓝藻大量生长的条件。对水体进行曝气复氧可以抑制蓝藻的生长。

| Abstract: | This text studies the influence of urbanization on recovery and growth of cyanobacteria in city river. The influence includes increasement of nutrition in river, extinction of higher water plants in river, variation of light intensity and reduction of reoxygenation efficiency as a result of stagnant water. The macroalgae puts a certain degree of curb on the growth of cyanobacteria, Ceratophyllum have a better effect than Hydrodictyon reticulatum. Appropriate light intensity is one element of eyanobacteria massive growth. Reoxygenation of water can inhibite the growth of eyanobacteria. |
