| 摘 要： | 通过观测三工河流域典型灌溉条件下不同长度畦田的水流推进和消退过程,推求其沿畦水流入渗历时线,结果表明,畦田长度为35和70 m时沿畦各点的入渗历时比较均匀.以灌水均匀度(Ed)和灌溉效率(Ea)为指标对各畦长的灌水质量进行评价,结果为:畦长35 m灌水均匀度最高,为91.4;,畦长70 m灌溉效率最高,为91.68;.

Effect of Border Check Length on Irrigation Quality under Representative Condition in Sangong River Valley |
| |
| Abstract: | The observation of the process of water current driving and reducing on various border check length under typical irrigation conditions in Sangong River Valley, the penetration of duration curve of water current was conducted. The results indicated that the penetration duration was more uniform in comparison with others when the border check length was 35m or 70m, and we evaluated irrigation quality based on E_d and E_a. The results showed that the irrigation equality was the highest, 91.4%, when the border check length was 35m. And the irrigation efficiency was the highest, 91.68%, when the border check length was 70m. |
