| 摘要: |
| 采用相关性分析方法研究了温度、盐度、营养盐等环境因子对黄河三角洲海参养殖池塘微型浮游植物多样性的影响。结果表明, 群落多样性指数H′值主要受营养盐特别PO43-?-P、NH4+-N限制, 温度、盐度对H′值影响不显著。丰富度指数d值受营养盐影响不显著。温度、盐度是d值的主要影响因素, 在温度15—30℃、盐度22—32范围之内, d值随温度、盐度升高而降低。均匀度指数J值受营养盐影响不显著, 但受温度、盐度影响作用较为明显, 在温度15—30℃、盐度22—32范围之内, ,J值随着温度、盐度升高而升高。由于池塘内温度、盐度、营养盐波动较大, 浮游植物群落并不稳定, 多样性一直处于受干扰状态。 |

| Abstract: |
| The impacts of temperature, salinity and nutrition salts on the diversity of Micro-phytoplankton in sea cucumber aquaculture ponds of Yellow River delta are studied using the method of correlative analysis. It is found that diversity index H′is limited by nutrition salts especial by PO43-?-P, NH4+-N primarily. H′is limited by nutrition salts especial by PO43-?-P, NH4+-N primarily. But the main limiting factors for richness index d is temperature, salinity and nutrition salts impact the d not obviously. In the temperature range of 15—30℃ and salinity range of 22—32, ddecline as the increasing of temperature and salinity respectively. Evenness index J is impacted by nutrition salts not obviously, but rising as the increasing of temperature and salinity in the temperature range of 15—30℃ and salinity range of 22—32 respectively. Micro-phytoplankton community is not stable and diversity is disturbed for the fluctuate of temperature, salinity and nutrition salts. |
