一、灌区基本情况及田间工程配套的重要性云谷川灌区灌溉面积为4.5万亩,自1978年基建结束后,耗用基建投资1043万元;1979～1984年又耗用小农水投资近500万元。建成了水库一座,蓄水765万立方米,三条干渠长65.8公里,支渠18条,长135公里,给灌区提供了充足的水源和输水工程。中干渠实受益2万亩,为当地的农业生产翻番创造了条件。但东、西干渠仅试了水,支渠以下工程基本未做,只是兴修了一些标准极低的不配
I. Basic Conditions of Irrigation District and the Importance of Field Engineering Package The irrigated area of Yunguchuan Irrigation District is 45,000 mu. Since the end of infrastructure construction in 1978, the infrastructural investment was 10.43 million yuan. From 1979 to 1984, the investment in small-scale farming was nearly 5 million yuan yuan.
