| 利用海马齿生态浮床技术原位修复海水养殖池塘, 通过周期性监测试验池塘浮游动物群落结构种类组成、密度和生物多样性变化趋势, 分析了浮游动物群落结构变化和养殖池塘水质改善之间的响应关系。结果表明:(1) 生态浮床对养殖池塘水质和沉积环境都表现出良好的改善功能, 表现为试验区较对照区, 水体透明度明显增加, 而TN、NH4+-N、TP、COD和底泥有机碳等污染物浓度均降低, 其中TN、COD和底泥有机碳呈现出显著性降低(P<0.05);(2) 试验区浮游动物的种类相比对照区的34种增加到40种, 趋于丰富; 各次采样中试验区浮游动物的密度均高于对照区, 平均由13559ind./L增加到15933ind./L; 试验区的Shannon-Wiener多样性指数(H')和Margalef种类丰富度指数(D)均高于对照区, 分别由初始的0.94和1.05提高到1.01和1.57。 |

| Abstract: |
| The community structure of zooplankton was studied during the process of in-situ restoration in a mariculture pond, the respond relationship between the biodiversity of zooplankton and the water quality was analyzed. The results showed: (1) Ecological floating bed showed a good function in improving mariculture pond water and depositional environments. Compared to the control area, transparency increased significantly, and the water chemical factors, such as TN, NH4+-N, TP, COD and sediment organic carbon, were all lower in the test area, especially TN, COD and sediment organic carbon showed decreased significantly (P<0.05). (2) The species of zooplankton in the test area increased to 40, more than that 34 species in the control area. Each zooplankton density in test area was higher than that in the control area, and increased from 13559ind./L to 15933ind./L in average. The biodiversity index also increased, of which Shannon-Wiener diversity index (H') and Margalef species richness index (D) increased from the original 0.94 and 1.05 to 1.01 and 1.57, respectively. The zooplankton diversity in test area showed higher recovery ability than that in control area, indicated that employment of in-situ restoration technology of ecological floating bed was effective in improving mariculture environment. |
