| 摘要: |
| 【目的】基于模糊集分析法对辽河支流浑河流域的汛期分期进行研究，为浑河流域洪水资源的合理利用提供参考。【方法】利用模糊集分析方法，以浑河流域沈阳站为代表站，用其1956-2000年45年的汛期旬径流量实测资料对浑河流域的汛期分期进行研究，并用45年的实测资料对汛期分期结果的合理性进行分析。【结果】6月上旬-7月上旬是浑河流域的前汛期，7月中旬-8月下旬是其主汛期，9月上旬-9月下旬是其后汛期。基于45年实测资料的分析表明，该汛期划分是合理且可靠的。【结论】将模糊集方法应用于浑河流域汛期分期是可行的。 |

| Abstract: |
| 【Objective】In order to provide references in the fields of using flood resources in Hunhe river basin reasonably and efficiently,the paper made a research on flood season staging of Hunhe river basin in Liaohe River tributaries based on the method of fuzzy sets analysis.【Method】The paper studied flood season aging of Hunhe river basin viewing the Shenyang station as the representative and using measured data of 45 years from 1956 to 2000 based on the method of fuzzy sets analysis and analyzed its rationality via the measured data of 45 years.【Result】It reached a result via years of ten-day runoff data:the first ten-day of June to the first ten-day of July was pre-flood season of Hunhe river basin;the second ten-day of July to the third ten-day of August was its main flood season;the first ten-day to the third ten-day of September was its latter flood season.The flood stage was reasonable and reliable based on the analysis of measured data of 45 years.【Conclusion】It is feasible to study flood season staging of Hunhe river basin based on the method of fuzzy sets analysis. |
