广州市流溪河水库监测布点优化研究

运用方差分析及模糊聚类分析，对流溪河水库监测布点进行优化研究，结果表明：水库水质良好，各监测点间及垂向采样点间均无显著性差异；4个库区监测点可分为3类，其余监测点可分为4类。综合考虑确定流溪河水库监测布点方案，应设置对照、控制、出水3类断面，共7个监测点，分别为玉溪河、吕田河、汇水区、库区3个和大坝监测点，每年6月进行垂向分层采样，其余月份进行表层采样。

The Monitoring Points Optimization Study of Liuxihe Reservoir in Guangzhou

By using the method of variance analysis and fuzzy clustering analysis, the optimization of the mo- nitoring points in Liuxihe reservoir were studied. The results show that the reservoir water quality was good, be- tween the monitoring points and the vertical sampling points were no significant difference. Four of the reservoir monitoring points could be divided into three classes, the rest of the monitoring points could be divided into four categories. Taken all factors into consideration, the Liuxihe reservoir monitoring points scheme was determined. Three kinds of sections （contrast section, controlling section and outlet section） were determined, and seven mo- nitoring points were included in the final monitoring scheme. Every June for vertical stratified sampling, surface sampling in the rest of the months.
