| 摘 要： | 贵州省灌区渠道兴建较早,渠系量水设施不配套,导致农业灌溉用水量长期以来不能准确测定。因此,探索简单易操作的农业灌溉用水量测定方法,对制定合理的水量分配制度具有重要意义。通过选取贵州省黔西县民乐灌区总干渠作为试点,采用流速仪测定该干渠不同水位下的流量,绘制水位流量关系曲线,并归纳该渠道水位流量关系经验公式,为落后山区无量水设施灌区的农业灌溉用水量探索一种简单实用的测定方法。

| Abstract: | The irrigation canals in Guizhou province are built in earlier time and the water-measuring facilities are not matching.This results in that the agricultural irrigation water amount can not be accurately determined for long time.Therefore,to explore the simple and easy operating agricultural irrigation water amount measuring method has important significance for making reasonable water allocation system.In this paper,the main canal of Minle irrigation district in Qianxi County of Guizhou province is selected as an example,the flow under different water level is measured by the channel flow meter to draw the curve of water level and flow channel and summarize the experience formula for the relation between water level and flow.This will supply a simple and practical method for water flow measurement of canal without water-measuring facility in mountain areas. |
