摘要:

基于三级净化技术对苏州池塘进行标准化改造,为探究其系统内各净化区浮游植物群落结构,2022年6—10月期间对扣/成蟹塘(T1)、南美白对虾塘(T2)、鲈鱼塘(T3)及草鲫混养塘(T4)各净化区水样的浮游植物群落进行分析,并通过浮游植物优势功能群评价水体营养状态。结果表明,T1~T4实验区内浮游植物物种数分别为85、65、59、66,浮游植物功能群数量为20、17、17、18。浮游植物功能群密度和生物量均表现为T4>T3>T2>T1,最大值出现在9—10月;Shannon-Wiener多样性指数依次为T1>T2>T3>T4;Margalef丰富度指数依次为T1>T4>T2>T3;Pielou均匀度指数浮游依次为T2>T1>T3>T4。植物优势功能群以代表富营养/超富营养水体的M+MP功能群为主演替为以广适应性的Lo功能群和富营养水体的J功能群;与浮游植物优势功能群相关的环境因子为TN和TP。基于浮游植物优势功能群可以评价水环境状态并能及时准确分析出水质变化情况。

Abstract:

To explore the phytoplankton community structure of the ponds after the standardization based on tertiary purification technology, from June 2022 to October 2022, the phytoplankton community in the water samples of each purification area of Eriocheir sinensis pond (T1), Litopenaeus vannamei pond (T2), largemouth bass pond (T3) and grass and crucian carp (Ctenopharyngodon idella- Carassius auratus) polyculture pond (T4) after the standardization in Suzhou City were tracked. Plankton community characteristics in different treatment areas were analyzed and studied, and the nutritional status of water was evaluated by phytoplankton dominant functional group. The results showed that the number of phytoplankton species in the T1-T4 experimental area was 85, 65, 59 and 66, respectively, and the number of phytoplankton functional groups was 20, 17, 17 and 18, respectively. The density and biomass size of phytoplankton functional groups were in the order of T4>T3>T2>T1, with the maximum value occurring from September to October. The Shannon Wiener diversity index was in the order of T1>T2>T3>T4, the richness index of Margalef was in the order of T1>T4>T2>T3, and the Pielou evenness index showed that the order of planktonic size was T2>T1>T3>T4. The dominant functional group of phytoplankton was mainly replaced by the M+MP functional group representing nutrient-entrophic/ultra-nutrient-rich water bodies, and the Lo-functional group with wide adaptability and the J-functional group of nutrient-rich water bodies. The environmental factors associated with phytoplankton dominant functional groups were TN and TP. Based on the dominant functional group of phytoplankton, the water environment status can be evaluated and the water quality changes can be analyzed in a timely and accurate manner.
