灌溉用水管理合轴相关图及其应用

Coaxal Coherent Chart and Its Application in Irrigation Water Management

灌溉用水合轴相关图把渠道供水能力，田间耗水强度，效益面积、灌水时间等因素融于一体，按照一定的关系以曲线或直线组绘成合轴相关图，通过该图即可初步设计渠道流量，选定灌溉面积，也可确定轮灌周期、轮灌面积等。该图查阅方便，容易掌握，查算结果可靠。

The coaxal coherent chart of irrigation water puts allfactors into one chart:channel transport capacity,field water consumption strength,benefit area and irrigation time.With the chart,it is easy to determine the channel flow rate,irrigation area,period and area of circular irrigation during primary design.The chart is easy to learn and use with reliable results.
