摘要
对特定流域的降水蒸发特征进行分析在区域水资源研究中具有十分重要的意义。文章以永翠河流域为例,对流域降水量的年际变化、年内分配、出现频率、流域内分布情况进行了分析,对流域蒸发量及其相关的旱涝指标亦根据流域自身特点,采用目前通用的分析计算方法进行有针对性的论述,并对各项分析结果进行了整体评价和总结。
Regional water resources,rainfall and evaporation characteristics of specific watershed are of significance in regional water resources research.Taking Yongcui Basin as an example,interannual variation,annual distribution,distribution frequency in the basin are analyzed,according to the basin characteristics the river basin evaporation and related drought index,targeted discussion is conducted by using the current popular calculation methods,and overall evaluation for each analysis result is carried out.
