为了探讨区域水资源总量的变化周期,根据郑州市水资源评价成果,采用小波分析方法对该市区域内的水资源总量的周期变化特性进行了分析.结果表明:郑州市水资源总量的变化具有8年、20年、52年左右的主周期;郑州市水资源总量变化存在多时间尺度的变化特征,大尺度的周期变化嵌套着小尺度的周期变化.分析结果可以为当地的水资源利用与管理提供参考依据.
為瞭探討區域水資源總量的變化週期,根據鄭州市水資源評價成果,採用小波分析方法對該市區域內的水資源總量的週期變化特性進行瞭分析.結果錶明:鄭州市水資源總量的變化具有8年、20年、52年左右的主週期;鄭州市水資源總量變化存在多時間呎度的變化特徵,大呎度的週期變化嵌套著小呎度的週期變化.分析結果可以為噹地的水資源利用與管理提供參攷依據.

In order to explore the periodic variation of the amount of regional water resources, according to the results of water resources assessment of Zhengzhou City, the period characteristics of water resources were analyzed by using the wavelet analysis. The results showed that the changes in total water resources in Zhengzhou City is possessed of the main cycle of around 8, 20, 52 years;there are multi-time scale variation characteristics of the period of large-scale changes in nesting period of the small-scale change. The analysis results can provide reference for local use and management of water resources.
