Abstract:

In this study, 9 sites were selected to analyze the water transparency and the variations of suspended matter in Liusha Bay, and these field investigations on these 9 sites were carried out 12 times in one year. The results were as follows: the annual mean water temperature of Liusha bay was 26.4 ℃, and the water temperature variation ranger from 19.0 to 31.9 ℃; The annual average water transparency was 133.3 cm, and the water transparency changed from 50 cm to 240cm; The contents of suspended matter were varied from 9.12 mg/L to 29.90 mg/L, and the annual mean value was 18.7 mg/L. The contents of suspended matter was significantly affected in different months（P＜0.05）. The whole variation trend of the contents of suspended matter was increased first, then decreased, and fluctuant change. The maximum of most selected sites was in May and the mean value was 26.81 mg/L. The horizontal distribution of the contents of suspended matter was shown that the higher contents was in 5th site、6th site、9th site and the lower contents was in 1th site、3th site、3th site. The coastal stations were higher than the channel and bay mouth.
