摘　　要：作者于１９９０年７月至１９９４年７月在粤东沿海采集到双壳类软体动物６５种，本文讨论了其生态类型、分布、区系特点及养殖和资源保护等问题。he specimens of 65 species of bivalve molluscs which were collected along the eastern coast of Guangdong Province from July 1990 to July 1994 are reported in this paper. They belong to 43 genera, 21 families and 6 orders. The result of species analysis indicates that 92. 3% of the species are distributed in tidal zone and 7. 7% below tidal zone. These species are divided into rock ecotype accounting for 33. 8%, silt ecotype 32. 3%, sand ecotype 23. 1% and mud ecotype 7. 7%. These lukewarm water species originating from the tropics and the subtropics have an advantage in quantity, and at the same time, there are a few species belonging to the strong tropics because of the influence of the warm currents in the South China Sea. Thus, these species form the bivalve molluscs fauna along the coast of eastern Guangdong as a part of the molluscs fauna of the northern marginal region in the Indo-West Pacific. The ways to develop the aquaculture of bivalve molluscs and make rational use of molluscs resources along the eastern.coast of Guangdong Province are discussed.
