中文摘要:
      本研究将农渔废弃物(花生秸秆和海湾扇贝壳)作为鱼礁材料添加物,利用礁体自身碳封存增加人工鱼礁碳汇潜能的可行性,并通过研究礁体附着生物的变化特征,探讨礁体材料添加物对人工鱼礁生态系统生物固碳的影响。结果显示,实验海区礁体附着生物的优势种为褶牡蛎(Ostrea plicatula Gmelin),添加了花生秸秆和海湾扇贝壳的人工鱼礁并未显著增加褶牡蛎的附着量(P>0.05)。通过对添加物礁体自身碳封存量的计算,海湾扇贝壳添加物单位实验礁的最小碳封存量为104.13 kg,最大碳封存量为260.32 kg;花生秸秆添加物单位实验礁的最小碳封存量为296.28 kg,最大碳封存量为740.70 kg;实验礁体添加物的总碳封存量达2802.87 kg。以此估算,如将实验所在的66.67 hm2礁区已投放的圆管型混凝土礁材料加入添加物,以海湾扇贝壳替代率为10%计算,至少可完成52040.00 kg碳的封存,以花生秸秆替代率为25%计算,礁体自身的碳封存量可达370350.00 kg。
英文摘要:
      In this study we investigated the potential alteration of carbon sequestration capability of artificial reef eco-system caused by the additives peanut straw and Argopecten irradias shell. After the intensity test four types of reefs with different proportions of additives were selected for experiments, and the effects of additives on carbon fixation by various fouling organisms adhering to the reefs were analyzed. It was found that Ostrea plicatula Gmelin was the dominant species of fouling organisms, and that additives did not apparently affect the fouling organisms. Peanut straw and A. irradias shell did not improve the carbon sequestration of O. plicatula Gmelin (P>0.05). The calculation of carbon sequestration in the reefs with addition of shell showed that the minimum carbon content per unit reef was 104.13 kg and 2.60 kg per hollow stere, and that the maximum content per unit reef was 260.32 kg and 6.51 kg per hollow stere. As for reefs with straw, the minimum content per unit reef was 296.28 kg and 7.41 kg per hollow stere; the maximum content per unit reef was 740.70 kg and 18.52 kg per hollow stere. The total carbon fixed by experimental reefs was up to 2802.87 kg. In this experiment each unit included 250 reefs. Assuming all the reefs within the marine area of about 66.67 hm2 contain additives, we calculated that reefs with 10% substitution of A. irradias shell could fix 52040.00 kg carbon, and that reefs with 25% substitution of peanut straw could fix 370350.00 kg carbon. Our results suggested that sequestration of reefs could be an effective method to improve carbon sinking. The effects of crop straws and shell as additives of artificial reefs need to be further investigated in the future.
