Abstract As a method of rural social investigation, participatory rural appraisal (PRA) is developing rapidly and applying widely in the international since the 1990*!s in 20th century. Its core concept is a process of communication and dialog between the outsiders and local people. The authors try to study the watershed landscape pattern and its effect elements by using the PRA tools involve semi-structure interview and problem tree to get and analyses local community information in Caijiachuan watershed of Shanxi Province. Combining with the spatial data management function of geographic information system (GIS), the integration and mapping of relative data is finished. Otherwise, some landscape elements are selected to do pattern analysis. The results show that PRA offers an active and effective approach to understanding and evaluating artificial disturbance, and is helpful to explain and dissect the actual pattern cause and future development by associating with GIS and remote sensing data.In the study area, the recent changing of landscape pattern is due to both the direct activities of the outside benefit groups and the local core problem, that is, the lack of water.
