摘　　要：从工程措施和非工程措施两个方面建立了流域防洪综合评价指标体系,利用主成分分析法对钱塘江流域2010年的防洪体系综合状况进行了综合评价。结果表明:流域各分区防洪体系综合状况的排名依次为杭州地区、金华地区、绍兴地区、丽水地区、衢州地区;工程措施和非工程措施是我国当前流域防洪的主要手段;要想切实提高流域的整体防洪实力,就必须将工程措施和非工程措施统一起来,协调发展。The article established synthetic evaluation indicator system of the basin flood prevention from the two aspects of engineering measures and the non-engineering measures and evaluated the Qiantang River basin flood control system integrated in 2010 using the principal components an- alytic method. The results show that the flood control system comprehensive status of each area in the basin lists as follows： Hangzhou area, Jinhua area, Shaoxing area, Lishui area and Quzhou area; engineering and non-engineering measures for flood control system in China is the main means.So, only integrates the engineering and non engineering measures, the overall strength of the flood control ean be improved.
