| 中文摘要: |
| 双齿围沙蚕是分布在河口和滩涂中的底栖生物。底质条件是影响双齿围沙蚕潜底和分布的重要环境因素。为探究底质粒径对双齿围沙蚕潜底能力和分布特征的影响，进而为其增养殖中生境的选择及适宜性评价提供依据，本研究量化分析了双齿围沙蚕在泥 （<75 μm）、细沙（125-250 μm）、中沙（250-500 μm）、粗沙（500-2 000 μm）、砾石（2 000-4 000 μm）、陶粒（4 000-8 000 μm）6种底质粒径下的潜底能力，并研究了其对6种底质粒径的自主选择性。结果表明：底质粒径对双齿围沙蚕的潜底时间、潜底率、潜底深度和分布率等指标均具有极显著影响（P <0.01）。此外，双齿围沙蚕对底质粒径的选择具有一定的特异性，在陶粒底质、泥底质和细沙底质下，双齿围沙蚕的潜底能力较强。陶粒底质下，双齿围沙蚕的潜底能力最强，分布率最高。本研究表明：双齿围沙蚕属于底质敏感型底栖动物，底质粒径会影响其潜底进程和种群分布。在自然海区中，以泥和细沙为主要粒径组成的滩涂是适宜双齿围沙蚕增养殖的底质条件。本文根据双齿围沙蚕的底质偏好以及其生态修复效应，设计了海水动物和耐盐植物共生系统，构建了以双齿围沙蚕为纽带的"海水鱼-盐生植物-沙蚕"海水生态系统模式。 |

| Perinereis aibuhitensis (Grube, 1878) lives in marine sediments of estuary or shoal areas, where substrate has some crucial environmental factors affecting its burrowing and distribution. In order to provide basic data for the habitat selection and suitability evaluations of the artificial aquaculture of P. aibuhitensis, this paper conducted a quantified analysis of its burrowing ability and explored its behavioral preferences in different substrates, including mud ( < 75 μm), fine sand (125-250 μm), medium sand (250-500 μm), coarse sand (500-2 000 μm), gravel (2 000-4 000 μm) and ceramsite (4 000-8 000 μm). The research results revealed that substrate grain size significantly affected the burrowing time, burrowing rate, burrowing depth and distribution rate (P < 0.01). Moreover, P. aibuhitensis demonstrated preferential selections relating to substrate grain sizes, had higher burrowing ability in ceramsite, mud and fine sand compared with other substrates. The strongest burrowing ability and the highest distribution rate were observed in ceramsite. The study indicated that P. aibuhitensis was sensitive to substrate grain size, which also had an impact on its burrowing process and population distribution. In the natural sea, substrates mainly composed of mud and fine sand are fit for aquaculture and stock enhancement. Based on behavioral preferences and ecological rehabilitation function of P. aibuhitensis, this paper proposes a symbiotic system of marine animals and halophytes, and constructs an ecosystem model of “Marine fish-Halophytes-Perinereis aibuhitensis” with P. aibuhitensis as the link. |
