非一致性水文频率计算的基因途径Ⅰ:水文基因遗传、变异和进化原理
Gene method for inconsistent hydrological frequency calculation.Ⅰ: Inheritance, variability and evolution principles of hydrological genes
摘要
Abstract
A stochastic hydrological process is influenced by both stochastic and deterministic factors.A hydrological time series contains not only pure random components reflecting its inheritance characteristics,but also deterministic components reflecting variability characteristics,such as jump,trend,period,and stochastic dependence.As a result,the stochastic hydrological process presents complicated evolution phenomena and rules.To better understand these complicated phenomena and rules,this study described the inheritance and variability characteristics of an inconsistent hydrological series from two aspects:stochastic process simulation and time series analysis.In addition,several frequency analysis approaches for inconsistent time series were compared to reveal the main problems in inconsistency study.Then,we proposed a new concept of hydrological genes origined from biological genes to describe the inconsistent hydrolocal processes.The hydrological genes were constructed using moments methods,such as general moments,weight function moments,probability weight moments and L-moments.Meanwhile,the five components,including jump,trend,periodic,dependence and pure random components,of a stochastic hydrological process were defined as five hydrological bases.With this method,the inheritance and variability of inconsistent hydrological time series were synthetically considered and the inheritance,variability and evolution principles were fully described.Our study would contribute to reveal the inheritance,variability and evolution principles in probability distribution of hydrological elements.关键词
