湫水河 meaning in English
qiushui he
Examples
- In a year the change of river flow is drastically and season distributes of runoff in river is mainly centralize in the summer in jia - lu - he , qiu - shui - he and pian - guan - he catchments . for example , the runoff amount from july to august accounts for 41 % , 58 % and 57 % of the annual runoff amount in the above three catchments , respectively
所选四条流域中，佳芦河、湫水河和偏关河三条河流径流量年内变化剧烈，季节分配不均，集中度高， 7 8月份径流量分别占各流域年径流量的41 、 58和57 。 - The impacts of soil and water conservation on river flow and soil - hydrology of jia - lu - he , tu - wei - he , pian - guan - he and qiu - shui - he catchments have been analyzed by the simulation and on - spot measuring methods according to data of during 1950 ' s to 1990 ' s . the selected catchments of the above four all are in the key area of soil and water conservation on the loess pleatu . the main results are as follows . the trend , reasons and critical year of annual river flow " change have been researched by rank correlation and maximum deviation division
本文以黄土高原水土保持重点区的佳芦河、秃尾河、偏关河和湫水河等四条流域为代表，采用定量与定性、模型模拟与实测对比相结合的方法，系统分析了上世纪50 90年代时段内水土保持对河川径流及土壤水文的影响，取得主要结果如下：采用秩相关和极差分割等定量评价方法，分析了四条支流径流量变化趋势、变化原因及发生明显变化的临界年份。 - The results showed that each river flow has a tendency to gradual decrease mainly by soil and water conservation in the above four catchments . the critical year of the river flow decrease was 1974 , 1974 , 1977 and 1974 for jia - lu - he , tu - wei - he , pian - guan - he and qiu - shui - he catchments , respectively . each river flow has been divided into prophase and anaphase period according to the critical year
结果表明：水土流失综合治理是引起径流量减少的主要原因之一；从上世纪七十年代以来，四条流域的年径流量均出现逐年减少的趋势；在研究时段内，佳芦河、偏关河、秃尾河和湫水河径流量发生趋势性减少的临界年份分别为1974年、 1974年、 1977年和1974年。
