摘　　要：利用主成分分析法对"七五"时期和"十一五"时期贵州省赤水河中段8个断面的水质进行了对比分析研究,结果表明:赤水河干流水质依然很好。由于中心城镇经过多年的规划与发展,积极建设城镇基础设施,城镇污水和酿酒废水均经处理达标后排放,使得W5断面的水质比"七五"时期的水质明显好转;其他断面水质的个别指标较前期发生了一定的变化;W4断面所在支流污染因子有增加的趋势,水质较前期有恶化趋势,应是重点控制的支流源。总体来看,赤水河干流水质优良,但也应当注意进一步采取多种措施防止支流水质发生变化。The water quality in Chishui River was assessed by using the PCA method in the'7th 5-year Plan'period and'11th 5-year Plan'period.The results showed that the water quality of trunk stream is still very well.The central town was planned and developed for many years,there is a well-desingn urban infrastructure,and the urban sewage and brewery waste water were treated before discharge standard.so the water quality of W5section has become better.Water-quality index of other sections has some changes.The source of tributary has to be controlled for that pollution factors become more and more.Overall,the water quality of trunk stream is still very well,but measurements should be taken to prevent water quality of tributary becoming worsen.
