光照强度及温度对青草沙水库蓝藻暴发风险的模拟试验
Simulation Experiment in Different Light Intensity and Temperature Gradients for Risk of Blue-Green Algae Outbreak in Qingcaosha Reservoir
摘要
Abstract
As Qingcaosha Reservoir is becoming a new important water source in Shanghai, its safety and water quality affects regional security and development directly. Blue-green algae bloom is one of key factors which is harmful to water safety. Simulation experiments to explore single factors of different gradients of temperature and light intensity and at the same time experiment were carried out in raw water. By those experiments and hydrological environment favorable environment for Cyanobacteria growing was studied. Microcystis aeruginosa (hereinafter called "M") and Scenedesmus quadricauda (hereinafter called "S") were used as experimental subjects, and light intensity and temperature were used as impact factors in this experiment. Hie results show M is more sensitive to temperature changing than S; under low light intensity M has higher adaptation and higher specific growth rate while S is more sensitive to high light intensity; doubling time of M is 20 d in raw water under condition of 3 300-6 600 lux and 24 t); water quality monitoring in local waters including head area and retention area should be enhanced, on the basis of which effective preventive measures should be put forward, and early warning level should be upgraded when continuous hot sunny weather is expected in summer.关键词
