采用剪鳍标记现场模拟法 ,测定了钻井噪声与振动对草鱼生长的影响。研究结果表明 ,钻井噪声与振动对草鱼生长有显著影响 ,其临界等效噪声和振动级约为 84 4dB和 90 2dB ,影响域径约为 8 5m ;污染持续时间和体重等生态因素能显著改变钻井噪声与振动对草鱼生长的污染效应。由于在污染消失后草鱼生长率能迅速恢复 ,这说明钻井噪声与振动对草鱼的影响是可逆的 ,并未产生器质性损伤 ,因此 ,用非听觉系统激起反应解释钻井噪声与振动对草鱼的影响机制可能是合理的。
The effect of drilling noise and vibration on the growth of grass carp was determined by the field simulation of the fin-fin marker. The results show that the noise and vibration of drilling have a significant effect on the growth of grass carp. The critical equivalent noise and vibration level are about 84 4dB and 90 2dB, and the influence diameter is about 85 m. The ecological factors such as duration of pollution and body weight can significantly change Pollution Effects of Drilling Noise and Vibration on Grass Carp Growth. Since the growth rate of grass carp can recover rapidly after the pollution disappears, it shows that the impact of drilling noise and vibration on grass carp is reversible and no organic damage is produced. Therefore, non-auditory system is used to stimulate reaction to explain drilling noise and vibration to grass carp The mechanism of influence may be reasonable.
