| 摘 要： | 对黄淮海平原低湿洼地鱼塘中异常细菌的矿化作用进行了初步研究，结果表明：（１）鱼塘水体中异养细菌的呼吸强度与鱼塘水体中的有机物质含量及温度密切相关；（２）鱼塘水体中异养细菌的生物量表现出明显的季节性变化；异养细菌的生物量在表层水及底层水之间的差异不明显。（３）鱼塘水体中异常细菌分解有机物质的动力学特点如下：开始时，鱼塘水体中有机物质的转化较少，随温度的增高及异养细菌生物量的增加，水体中的矿化作用逐渐

| Abstract: | The mineralization of heterotrophic bacteria in low- wetland fish pond of the Huang-HuaiHai plain was studied in 1993. The results were oboined as foIlows: (1) The respiration rate of heterotrophic bacteria were related with the content of organic matter and the water temperature of fish ponds. (2) The bacteria biomass of fish ponds showed a clearly seasonal change. but the distribution of heterotrophic bacteria biomass showed no difference in surface and bottom water. (3) The dymamic characteristics of heterotropic bacteria decomposition organic matter were as follows: At first, the transfered organic matter was little, following the temperature and the bacteria biomass, the mineralization increased and reched the maximum in autumn, and then stopped with decaresein the temperature. (4) The intensities of mineralization organic matter varied in fish ponds to stock different fishs. |
