我省万亩以上渠灌区184处,有效灌溉面积1488万亩,一般年总引水量60—70亿立米,对农业增产起着重要作用。但目前还存在一些问题,未能充分发挥效益。①不少灌区没有总体规划。主要是灌溉水源少,控制面积大,灌溉保证率低。全省万亩以上灌区的设计灌溉面积2445万亩,但实际有效灌溉面积只有60％,而且平均只灌三水多。②渠
Irrigation area of more than mu mu 184, the effective irrigation area of 1488 mu, the general annual total of 670 billion cubic meters of water diversion, the increase of agricultural production plays an important role.

Mainly less irrigation water, control of large area, low irrigation guarantee rate. The irrigated area of more than 10,000 mu in the whole province is designed with an area of 2445 mu irrigated land, but the actual effective irrigated area is only 60%, and the average irrigation area is only 3 Sanshui. ② canal
