Abstract: By choosing a typical experimental site which located on the Soil Loss Mainly Harnessing Area of China in the western part of Liaoning, following the happening theory and dominant factor principle, using the methods of the layer analysis and the cluster analysis, based on the dividing land types, confirming land resources evaluation index systems, developing the layer analysis models for land resources evaluation, constructing judging matrix, sorting order and coincidence test, the land resources of small watershed in Beisijia were classified into six classes, and the adaptability evaluation of the six classes land resources were done. Meanwhile, the directions of ecological environment restoration and land resources utilization for the small watershed were put forward. These results can provide scientific bases for not only the quantitative evaluation of land resources, but also the ecological environment protection and land resources development and utilization in hilly semi-arid area of China.
