摘要

对大面积水土保持治理措施的保存面积进行核实是分析计算水土保持减水减沙效益的基础。笔者通过应用土地详查成果，对黄河中游黄土丘陵沟壑区的晋西北14县及黄土高原沟壑区的陇东8县（市）进行了梯田、坝地，造林、种草措施保存面积的核实，得出了黄河中游两个不同类型区的大面积各项水土保持治理措施的保存率，并用晋西典型调查进行验证，为黄河中游地区水土保持措施减水减沙效益的研究提供了可靠的基本数据。

Abstract

To check the large area preserved by soil and water conservation measure is the bases to analyse and calculatethe benefits reducingrunoff and sediment by the measure. This paper has checked the true areas preserved byfourcontrol measures of terraces

flatland.forest.grass land in both 14 counties ofwest Shanxi praince and 8 counties ofeast Gansu province on the hilly and gully areil of loess plateau in the middle reaches of the Yellow River by use ofthe results of detailed land survey. The prexervation rata of each control measures has been obtained in broad regionin the above two types of area. The rate has been checked by the result of typical investigation in west Shanxiprovince.A realible basic data has been set for the study of benefits to reduce runoff and sediment by the controlrneasures in the middle reaches of the Yellow River.
