尾河 meaning in Chinese
ogawa
Examples
- One exception is tu - wei - he catchment where underground runoff is the primary part of river flow . its runoff season distribution is much uniformity . its runoff amount of july to august accounts is 24 % of the annual runoff amount
但以地下径流补给为主的秃尾河，径流量的季节分配相对均匀， 7 8月份径流量占年径流量的24 。 - 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。
