The vital content of the beautiful countryside construction is to setup and implement the planning of modern agricultural landscape, which takes agricultural landscape classification as one of the bases. In this paper, on the basis of the definition and the characteristics of agricultural landscape in China as well as the requirements of the new countryside construction, the classification methodology of agricultural landscape was proposed on the bases of considering leading functions, land use types, micro-topography and soil conditions of agricultural landscape. A case study was conducted in Yukou Town of Pinggu District of Beijing, where 4 classes, 15 subclasses, and 46 units of agricultural landscape were classified and mapped with Geo-statistics models and GIS. Results showed that this methodology takes into account of the natural and human factors of agricultural landscape, thus, can not only reflect the leading function and spatial morphological characteristics of agricultural landscape, but also meet the requirements of agricultural landscape planning in the beautiful countryside construction.
