打坝淤地是我省群众治沟造田的传统经验,在晋西已有500多年的历史。淤地坝对于缓洪减沙、固沟防冲、变荒沟为良田、改变山区的农业生产条件有着显著的作用。建国30多年来,我省坝地面积由1.3万余亩发展到220多万亩;在筑坝规模和施工技术等方面都有很大发展。户包治理小流域的出现,为打坝淤地开创了新的局面,同时也提出了新的问题。本文着重就我省兴建大、中型拦泥淤地坝的必要性和可行性,作一初步探讨。 Dam construction is a traditional experience of mass grave farming in our province and has more than 500 years of history in western Shanxi. Warping dam for slowing sediment reduction, solid ditch anti-redirection, variable wasteland as fertile land, change the mountain agricultural production conditions have a significant role. Over the past 30 years since the founding of the People’s Republic of China, the area of ​​dams in our province has grown from more than 1.3 million mu to more than 220 million mu; great progress has been made in dam construction scale and construction technology. The emergence of small parcels to manage small watersheds opened up a new situation for damming dam sites and raised new problems. This article focuses on the construction of large and medium-sized dam in our province the necessity and feasibility of silt dam for a preliminary study.
