广东地区水资源丰富,各灌区灌溉引水条件较好,大中型灌区比例较高,然而节水灌溉工程面积比例仅为8%,低于东南沿海其他地区的节水灌溉水平,灌溉水有效利用系数远低于国内其他省份。以广州市流溪河双岗灌区为试点,建设灌区灌溉水有效利用系数在线监测系统,深入了解灌区农田工程灌溉用水情况,有助于制定科学的灌溉制度,实现灌区内水资源优化配置;有助于提高灌区灌溉管理水平,促进节水农业发展;有助于实现灌区水资源高效利用。
The water resources are abundant in Guangdong. Irrigation and diversion conditions are good in all irrigated areas, with a large proportion of large and medium-sized irrigated areas. However, the proportion of water-saving irrigated areas is only 8%, lower than that of other areas along the southeastern coast, and the effective utilization coefficient Far below other provinces in China. Taking Guangzhou Liuxihe Shuanggang Irrigation District as a pilot project, the construction of irrigation water use efficiency online monitoring system in irrigation district will provide a better understanding of irrigation water use in farmland irrigation projects, which will help to formulate a scientific irrigation system and optimize the allocation of water resources in irrigation districts. Help to improve the irrigation management level of irrigated area and promote the development of water-saving agriculture; help to achieve the efficient use of water resources in irrigated areas.
