简介:在水质量变量上理解浮游植物和他们的依赖的模式,能帮助发育营养正常促进剂湖的管理。这研究的目的是决定在金尚·莱克,与cyanobacteria优势和microcystin生产联系的水质量和环境因素位于Taihu分水岭的headwater的一个副热带的湖,中国。在金尚·莱克从10个学习地点每月收集的水样品包括全部的氮(TN)为淡水水藻和物理化学的参数的种类分布被分析,氨(NH4+-N),硝酸盐(NO3-N),总数磷(TP),并且叶绿素一(Chl--一)从2008年6月到2009年5月。金尚·莱克被发现是发育营养正常促进剂,基于计算营养的州的索引(TSI)。4.33mg/L的平均TN在学习时期期间超过了中国的表面水质量标准。TP显著地与相对许多cyanobacteria和Microcystisbiovolume被相关,显示它在调整cyanobacteria的重要角色。Microcystis,淡水藻类的一种,和Oscillatoria是在从6月的金尚·莱克的主导的cyanobacteria到2008年11月。Cyanobacteria优势走水路被调整温度和TP。主要部件分析进一步显示那microcystin生产最走水路被影响温度,TP,和cyanobacteria生物资源。结果建议在夏天的TP的控制能在金尚·莱克减轻cyanobacteria优势和microcystin生产,并且靠近的监视应该在夏天被承担。
