摘　　要：采用实验生态学方法研究环境因子对缢蛏 (Sinonovaculaconstricta)滤水率的影响规律。结果表明 :温度、盐度和pH对缢蛏的滤水率有极显著影响 (F >F0 .0 1)。当温度、pH值分别在 15～ 30℃和 6～ 9时 ,缢蛏的滤水率呈一个峰值变化 ,当温度为 2 0℃、pH值为 8时 ,其滤水率分别达到最大值 ;当盐度在 6～ 30时 ,随着盐度的增大缢蛏的滤水率亦逐渐增高。The effects of environmental factors on the filtration rate of the constricted tagelus (Sinonovacula constricta) were studied in laboratory. The results showed that the water temperature, salinity and pH had distinct effects on the filtration rate of the constricted tagelus. The maximum filtration rate appeared at temperature 20℃. The filtration rate increased with the increase of salinity in the range of 6～30. It increased with the increase of pH value in the range of 6～8, and decreased at 9. The maximum appeared at pH 8.
