| 摘 要： | 乌中灌区是贵州省的大型灌区之一，灌区工程多修建于上世纪50至70年代。至今，大多渠道老化难以正常工作，渠系老化率平均达0.55；灌区有效灌溉面积锐减，现状有效灌溉面积为设计灌溉面积的37%-54%，其中改种占相当比例；灌溉水利用系数较低，在0.39—0.42之间。本文以5个典型样点灌区为例，分析渠系老化对农田灌溉的影响。

| Abstract: | Wuzhong Irrigation District is one of the biggest irrigation districts in Guizhou Province.The irrigation project was constructed from1950s to 1970s.Up to now,most of irrigation canals can not work well because of aging,the average aging rate of canal system is 0.55,so that irrigation area and water efficiency of irrigation declines sharply.The present effective irrigation area accounts for 37%~54% of the designed irrigation area.Utilization coefficient of irrigation water is low in between 0.39~0.42.In this study,five typical irrigation districts are investigated and the impact of irrigation district system aging on farmland irrigation is analyzed. |
