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=0.003936L~(2.812)。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。
The biological characteristics, geographical distribution, population structure and ecological characteristics of Dendrocalamus obliquus in the northern Yellow Sea were investigated comprehensively. The results showed that the mussels were mainly distributed in the subtidal zone (0 ~ -2 m) along the coastline between 39 ° 25 ’~ 39 ° 39’ north latitude and 122 ° 35 ’~ 123 ° 04’ east longitude and inhabit sand and mud Quality of the sea floor, is a near-shore eco-organisms; body weight and shell length was power function correlation, regression equation W = 0.003936L ~ (2.812). In this paper, the community composition and ecological distribution of ecological groups in the habitat of Lepidoptera clam were also analyzed. The characteristics of environmental ecology and basic ecology were also discussed. The niche and current status of Lemna clam were also discussed.
