| 摘 要： | 为揭示池塘内循环流水养殖模式(IPA)池塘和传统池塘养殖模式浮游植物群落的生物多样性,开展了对两种模式水质、浮游植物群落的监测。结果表明,IPA模式共鉴定出浮游植物64种(属),传统池塘养殖模式共鉴定出浮游植物49种(属),且IPA模式池塘浮游植物的平均密度和平均生物量为113.55×106 ind·L-1和52.79 mg·L-1,均高于传统池塘养殖模式的78.37×106 ind·L-1和23.22 mg·L-1。IPA模式浮游植物Shannon-Wiener多样性指数(H’)平均值为3.80,Margalef指数(D)平均值为2.25,均高于传统池塘;典范对应分析(CCA)显示,IPA模式影响浮游植物的主要驱动因子有水温、高锰酸盐指数、总氮、总磷、总有机碳,而传统池塘养殖模式影响浮游植物的主要驱动因子有总氮、总磷、总氨氮、亚硝态氮。

| Abstract: | In order to reveal the biodiversity of phytoplankton in IPA model and traditional aquaculture ponds, water quality and phytoplankton communities were monitored. The results showed that 64 phytoplankton species were identified in the IPA model, and 49 phytoplankton species were identified in the traditional aquaculture pond, and the average density and biomass of phytoplankton in the IPA model were 113.55×106 ind·L-1 and 52.79 mg·L-1, which were higher than the 78.37×106 ind·L-1 and 23.22 mg·L-1 in the traditional aquaculture pond. The mean values of Shannon-Wiener diversity index (H') and Margalef diversity index (D) in IPA mode were 3.80 and 2.25 respectively, which were higher than those in the traditional aquaculture pond. Canonical correspondence analysis (CCA) showed that water temperature, potassium permanganate index, total nitrogen, total phosphorus and total organic carbon were the main driving factors affecting phytoplankton in IPA mode; total nitrogen, total phosphorus, total ammonia nitrogen and nitrite nitrogen were the main driving factors affecting phytoplankton in the traditional aquaculture pond. |
