摘　　要：采用实验生态学方法,研究了干露、水温、盐度和底质对橄榄蚶成贝存活的影响.结果显示:在湿度65%–75%情况下,随着温度的上升,橄榄蚶成贝的干露能力逐渐降低;在海水盐度24.6和pH 7.8的条件下,橄榄蚶成贝存活的最适海水温度范围为5–19.8℃;在海水温度19.8℃和pH 7.8的条件下,橄榄蚶成贝存活的最适盐度范围为15–30;在海水温度20–23℃、盐度21.8和pH 8.1的条件下,橄榄蚶成贝在多种底质中均能存活,其中以泥砂质和泥质为宜.Through experimental ecology methods,effects of exposure,water temperature,salinity and substrate on survival rate of adult Estellarca olivacea were studied.Results showed that when the humidity is 65% to 75%,adult Estellarca olivacea’s ability of exposure declines with the rising of experimental water temperature;under the conditions of water salinity 24.6 and pH 7.8,the most suitable water temperature for adult Estellarca olivacea is 5 to 19.8℃;under the conditions of water temperature 19.8℃ and pH 7.8,the optimal salinity for adult Estellarca olivacea is 15 to 30 and under the conditions of water temperature 20℃ to 23℃,salinity 21.8 and pH 8.1,adult Estellarca olivacea can survive in many kinds of substrate,among which argillo-calcareous and argillaceous are the best two.
