摘要

黄河水土保持生态工程藉河示范区地处黄土丘陵沟壑区第Ⅲ副区

地形破碎

沟壑纵横

沟道侵蚀明显

淤地坝建设是该地区沟道治理的一项重要水土保持工程措施。该区淤地坝建设形成了高坝小库容

防洪要求高.工程投资大

筑坝方式单一等区域特点。规划以单坝为主

技术指标适当放宽

合理布设骨干工程

适当提高防洪标准等技术途径

使淤地坝在促进当地社会经济发展方面发挥着重要作用。

Abstract

The Xi he River demonstration district

as an ecological project of soil and water conservation in the Yellow River basin

is located in the third sub-area of hilly gully area on the Loess Plateau.Its topogra-phy is typical of numerous valleys and gullies

where gully erosion is one of the main erosion processes. Con-struction of check dam is an important engineering measure for gully management in the region. In practice

many regional experiences of check dam construction have been developed

such as small reservoir capacity with high dam

high standard against flood

huge invest

and single form of construction. In planning

some technical methods-single dam dominated

relaxing technical indexes moderately

arranging main projects reasonably

and increasing standard against flood moderately-have been popularly used. Check dam plays an important role in promoting social economic development in the area.
