| 摘 要： | 为了研究灌区渠道密度与渠系水利用系数之间的关系，首先从分析渠道水的渗漏情况入手,分析了渠系水利用系数与渗漏之间的关系,建立了在相同衬砌条件下渠道密度与渠系水利用系数之间的数学关系。然后提出有关渠道密度概念，这一概念的提出有利于灌区渠道分布合理性的进一步评价。渠道密度与渠系水利用系数两者之间关系式的确立，有助于从理论上评价渠道分布对渠系水利用系数的影响。

| Abstract: | In order to research the relationship between canal density and canal-system water use efficiency,the condition of canal seepage is analyzed,and the mathematical relation between the canal density and canal-system water use efficiency is established for different canal densities under the same canal lining conditions.Then the concept of canal density is defined.This concept is used to evaluate rationality of canal distribution.Establishing the relation between canal density and canal-system water use efficiency can facilitate the evaluation of the influence canal distribution on canal-system water use efficiency. |

| Keywords: | canal density canal-system water use efficiency mathematical relation |
