摘　　要：以我国北方土石山区的淮河流域为研究对象,采用水土流失主导因子空间分析和水土保持主导生态功能评价的方法,提出淮河流域水土保持监测分区。结果表明:1)将淮河流域水土保持监测分区划分为7个一级监测区(水土流失类型监测区)和15个二级监测区(水土保持功能监测区),阐明淮河流域水土保持监测的主要生态功能及空间分布格局;2)淮河流域水土保持监测的主导生态功能包括水源涵养、土壤保持、农田防护、防风固沙4方面,不同功能监测区面积表现为农田防护区(占流域面积的61.0%)>土壤保持区(占26.4%)>水源涵养区(占7.3%)>防风固沙区(占5.3%)。Soil and water conservation monitoring is one of the main tasks and essential for improving ecological environment. It is also an important guarantee of socio-economic sustainable development. Taking the Huaihe River Basin in rocky mountain areas of northern China as the research area, we propose a two-grade zoning method of soil and water conservation monitoring, by combining the principal factor analysis and assessment of different ecological functions in soil and water conservation. The results showed that： 1 ） the Huaihe River Basin could be divided into seven first-grade zones （types of soil and water erosion monitoring areas） and 15 second-grade zones （functional monitoring areas of soil and water conservation）, which can demonstrate the main ecological functions and spatial distribution patterns of soil and water conservation monitoring. 2 ） The principal ecological functions of soil and water conservation monitoring of the Huaihe River Basin include water conservation, soil conservation, farmland protection, wind prevention and sand fixation. The areas of different function monitoring zones follow the order of farmland protection area （61.0% of all the entire basin） 〉 soil conservation area （26.4%） 〉 water conservation area （7.3%） 〉 wind prevention and sand fixation area （5.3%）.
