摘　　要：通过分析近5年石梁河水库库区及入库河道(新沭河)水质变化情势和营养状态指数,发现氮、磷等营养盐质量浓度以及水温、水位是暴发蓝藻水华的关键驱动力,结合石梁河库区TN、TP现状质量浓度,提出夏季时期水温上升、水位下降会带来蓝藻水华暴发的潜在风险。By analyzing the changes in water quality and nutritional status index of the Shiliang River reservoir area and the incoming river channel(Xinshu River)in the past 5 years,it was found that the quality concentration of nutrients such as nitrogen and phosphorus,as well as water temperature and level,are the key driving forces for the outbreak of cyanobacterial blooms.Combined with the current quality concentration of TN and TP in the Shiliang River reservoir area,it is proposed that the potential risk of cyanobacterial blooms will be brought about by the rise of water temperature and the decrease of water level in summer.
