【摘要】 由于北方城市再生水景观水体本身具有受到外界干扰多、生态系统脆弱,自净能力差、水量较小,流速缓慢,水体内氨磷营养盐较地表水高等特点,藻类极易在夏季过度繁殖生长,产生水华,水华一旦爆发,将导致水体散发异味,透明度下降,溶解氧降低,水生植物和鱼类大量死亡。严重影响景观水体的观赏效果,甚至会危害民众的健康。以往的研究表明水华是一个缓慢、可以预测的过程。早期的预测、管理是控制水华爆发的有力手段,可以实现事半功倍的效果。本项目结台以往多年的研究成果,开发北方城市再生水景观利用水华预警系统,为下一步建立基于水华控制的再生水景观利用运行维护系统奠定基础。更多还原

【Abstract】 Water-bloom is easy to breakout in scenic water which utilizes reclaimed water as source water.It is the serious result of water-bloom that water transparency declines, dissolved oxygen falls and water body becomes dark green or blue green etc.The relation of alga growth and monitoring data was researched in this paper to forecast water-bloom.It had been proved that water-bloom is a predictable process.Early management is important to control water bloom.Our research achievements of many years would be combined to water-bloom early warning system in north city in China.更多还原
