The salinity reducing rate was 5/d and the pH rising rate was 0.2/d. The effects of salinity on oxygen consumption rate (ROc) and ammonia excretion rate (RAm) in S. constricta are extremely significant (F>F0.01) and when salinity changes from 6 to 30, there is a peak value for both ROc and RAm (1.310 2 mg·g-1·h-1, 227.372 5 μg·g-1·h-1, shell length (3.916 7±0.265 8) cm) at salinity 22. However, the effects of pH on RAm are not significant (F<F0.05) that the RAm changes a little at the pH range of 6-9. But at this pH range, the ROc has significant effects on RAm of S. constricta that at pH 8 the RAm gets its peak (153.030 5 μg·g-1·h-1, shell length (3.776 6±0.216 2) cm). Thus, salinity and pH are important environment factors for the respiration and extraction of S. constricta and at pH 8 and salinity 22 or so, S. constricta can grow well without exhausting much energy and can make use of the organic matters and diet remnants in the sediments. </em></p><p class='subject'><strong>关 键 词：</strong><a href='/subject/article.aspx?id=3702249' target='_blank'><b
