溱湖水质时空变化规律
Spatial-Temporal Changes laws in Water Quality of Qinhu Lake
摘要
Abstract
The water quality of Qinhu Lake was monitored from January 2012 to December 2012. Annual mean concentration of total nitrogen (TN) was Ⅲ class level, concentration of total phosphorus (TP) and ammonia nitrogen (NH3-N) were Ⅱ class level. Statistics also show that, the three indexes are decreasing gradually with time in the first half year, while rising in the second half year. The content of nitrogen and phosphorus in east area of Qinhu National Wetland Park are more than that in the entrance of east region. The content of nitrogen and phosphorus in water inlet is higher than that in water outlet in the first half year. Conversely , the content of nitrogen and phosphorus in water inlet is lower than that in water outlet in the second half year. Average concentration of TN, NH3-N and TP in water inlet were 1.183 mgoL-1, 0.274 mgoL-1 and 0.12 mgoL-1 respectively, and those in water outlet were 0.998 mgoL-1, 0.237 mgoL-1 and 0.0 108 mgoL-1 respectively. Thus, Qinhu Wetland plays a role to remove nitrogen and phosphorus in water of Qinhu Lake.关键词
