摘　　要：为科学合理布设抚河流域综合治理监测点,采用聚类分析方法开展监测点布局优化研究,结合相对偏差分析和方差分析开展布局优化合理性分析,提出抚河流域综合治理监测布局优化方案,在布设流域综合治理监测点时,在河流干流上中下游分别布设2个监测点,较大的支流在上游和下游分别布设1个监测点,较小的河流则在入干流处布设1个监测点。结果表明:抚河流域综合治理监测布局优化后,监测点由初始的40个减少为16个,减少幅度达60%;优化后监测点仍然覆盖了抚河流域上中下游、干支流和重要节点;优化后各类别、各指标之间相对偏差较小,优化前后各类别、各指标无显著差异。To set up the lay out monitoring points scientifically and reasonably for comprehensive management of watershed,the Fuhe River basin was taken as an object.Cluster analysis method was adopted to optimize the monitoring layout.The rationality analysis of layout optimization was carried out by combining relative deviation analysis with variance analysis,and the optimization scheme of monitoring layout was constructed in the Fuhe River basin.According to the optimization scheme of monitoring layout,two monitoring points were set up in the upstream,middle and downstream of the river trunk respectively.One monitoring point was set up in the upstream and downstream for the larger tributaries,and for smaller rivers only one monitoring point was set up at the river confluence.The results show that after optimization,monitoring points were reduced from 40 to 16,accounting for 40%of the initial monitoring points.The optimized points still cover the upper,middle and lower reaches,trunk and tributaries and important nodes of the Fuhe River basin.After optimization,the relative deviation of each category and index is small,and there is no significant difference between the indicators of each category before and after optimization.
