| 摘 要： | 附着生物初级生产力、叶绿素a含量和碱性磷酸酶活性能够指示其对水质的净化能力.本实验选择了5种具有不同表面结构和理化特性的人工载体(载玻片、PVC片、软性载体、组合载体和立体载体),野外原位测定了不同人工载体上附着生物的初级生产力、叶绿素a含量及碱性磷酸酶活性.结果表明:人工载体的理化性状是影响其上附着生物群落稳定、生产力、叶绿素a含量和碱性磷酸酶活性的重要因素.在野外原位条件下,附着生物通常在8～10 d就可以达到最大附着量,此时,其初级生产力、叶绿素a含量和代谢活性等均处于最佳状态.在所选择的5种人工载体中,立体载体和软性载体上附着生物的初级生产力、叶绿素a含量及碱性磷酸酶活性均显著高于其他3种载体,其中立体载体上附着生物净初级生产力最高可达164.21 mgO2/(g.h),且与软性载体相比,立体载体价格相对经济,因此立体载体是一种比较理想的用于水质修复的人工载体.

| Abstract: | Primary production,chlorophyll-a and alkaline phosphatase activity of periphyton can indicate its water purifying capacity.Five artificial substrates with different surface configurations and physicochemical characteristics were selected during this experiment.They were glass slide,PVC film,soft substrate,combined substrate and elastic substrate.The primary production, chlorophyll-a and alkaline phosphatase activity of periphyton attached on these five different substrates were investigated in situ.The results showed that physicochemical characteristics of artificial substrates were proved to be the key factors affecting the stability of periphyton community,primary production,chlorophyll-a and alkaline phosphatase activity.Generally during in situ attachment process,the maximum mass of periphyton appeared on the 8th to 10th day while periphyton primary production,chlorophyll-a and metabolic activity were also showed the highest.Primary production,chlorophyll-a and alkaline phosphatase activity of the periphyton attached on elastic and soft substrates were significantly higher than those on other three substrates.The net primary production of the periphyton attached on the elastic substrate was 164.21 mgO2/(g·h),the highest of those on the five artificial substrates.Compared with the soft substrate,the elastic substrate was more economic and better optimal artificial substrate for water quality restoration. |
