中文摘要:
      比较全面地调查研究了黄海北部凸镜蛤的生物学特性、地理分布、种群结构和生态特点。结果表明:该海区的凸镜蛤集中分布于北纬 39°25'~39°39',东经 122°35'~123°04'沿岸的潮下带(0~-2 米),栖息于砂泥质海底,属近岸生态型生物;体重与壳长呈幂函数相关,回归式为 W=0.003936L2.812。本文中还分析了凸镜蛤栖息区生态类群的群落构成及生态分布,阐述了环境生态和基础生态的特点,并探讨了凸镜蛤的生态位及现状。
英文摘要:
      The biological characteristics, geographic distribution, population structure and ecological speciality of Dosinia gibba in the north Yellow Sea were investigated. The results indicate that D.gibba in this sea area are cetrally scatter-ed in the subtidal zone (water depths of 0-2m) in 39°25'~39°39'N,122°35'~123°04'E. They perched in the sandy silt bottom of the sea. They are the creatures of near land ecotype. Most of them are two year of age. The relationship between body weight and shell length is exponential. The regression is egpressed as W=0.003936L2.812. The communities constitution and the ecological distribution of the mores in D.gibba settlement were analysed as well. And the sperciality of water che-mical and nutrient environment were elucidated. The ecological niche and system of D. gibba were discussed. D.gibba settled in the fauna of bivalve molluscs of this sea waters. The maximum biomass is 0.44g /m2 and abundance is 0. 06 ind/m2,Here they have not become the dominance population yet. It is 28-30℃ that the yearly changes of vvater temperature in the present waters. The salinity is changed between 20‰and 32‰.
