摘要
统计巢湖西北岸河流入湖口水体4~11月的检测数据,分析研究作为蓝藻预警因子的叶绿素a与营养盐因子的时空分布特征和相关性,结果显示南淝河水体的总磷总氮均值浓度最高,叶绿素a浓度在8月达到峰值,总磷与叶绿素a浓度呈现高度相关性,研究为巢湖沿岸不同入湖河流削减氮磷治理以及提高叶绿素a作为蓝藻预警因子的准确性提供参考依据。
Data from April to November were collected from rivers in the northwest bank of Chaohu Lake,and the temporal and spatial distribution characteristics and correlation between chlorophyll a and nutrient factors were analyzed.The results showed that the average concentration of total phosphorus and nitrogen in Nanfei River was the highest,and the concentration of total phosphorus and chlorophyll a showed a high correlation.The research provided reference for reduc ing nitrogen and phosphorus control and improving the accuracy of chlorophyll a as an early warning factor of cyanobacteria.
