摘要: 对两种模式轮虫培育池的悬浮物结构及动态进行了比较研究.结果表明,颗粒悬浮物总量波动在6.76~65.39mg·L-1之间.静水池塘14#颗粒悬浮物平均值为11.50mg·L-1,其中颗粒有机物占66.8%,浮游植物占30.5%,浮游动物占5.3%,颗粒腐质和细菌占31%,颗粒无机物占33.2%.流水池塘82#池颗粒悬浮物平均值为41.83mg·L-1,其中颗粒有机物占70.4%,浮游植物占30%,浮游动物占1.2%,颗粒腐质和细菌占39.2%,颗粒无机物占29.6%.颗粒悬浮物含量静水轮虫池小于流水轮虫池.轮虫培育池是一类特殊类型的生态系统,消费者以褶皱臂尾轮虫为主,群落结构简单,生境易变,这些都会影响水层颗粒悬浮物的动态,造成其含量的较大波动和构成的改变.轮虫培育池生态系统颗粒悬浮物中以颗粒有机物所占比例较大,颗粒腐质和细菌所占份额与浮游生物量相当.

Abstract: A comparative study on the structure and dynamics of suspending particulates in static and current water rotifer-culturing ponds showed that the total content of suspending pariculates varied from 6.76 to 65.39 mg稬-1, with an average of 11.50 mg稬-1 in static water ponds, among which, organic pariculates accounted for 66.8%, while inorganic particulartes occupied 33.2%. In the organic pariculates, both particulate detritus and bacteria accounted for 31%, while phytoplankton and zooplankton occupied 30.5% and 5.3%, respectively. The amount of suspending pariculates in current water ponds was 41.83 mg稬-1 in average, among which, organic pariculates accounted for 70.4%, while inorganic pariculates occupied 29.6%. In the organic pariculates, both particulate detritus and bacteria accounted for 39.2%, while phytoplankton and zooplankton occupied 30% and 1.2%, respectively. The content of suspending pariculates in static water ponds was less than those in current water ponds. Rotifer-culturing pond was a special type of ecosystem, where Brachionus plicatilis was the major consumer, its community structure was sample, and the abiotic factors were easy to be changed, which resulted in the dynamics of suspending pariculates content in ponds. The ratio of organic to total pariculates in rotifer-culturing ponds was higher, and the contents of both particulate detritus and bacteria were corresponding to that of plankton.
