Abstract:: In order to provide the basis for the construction of ecological restoration project, using the method of the principal component analysis and the multiple linear regression analysis, the dominant driving force factors of ecological degradation of the ecological restoration area in Beipiao city of Liaoning Province were studied based on the soil remote sensing interpretation data of 1998, 2003 and 2008 and the relative data of statistical yearbook of history. The results showed that the rank of the ecological degradation effective factors is: land reclamation ratio > per capita raising the livesto > per capita economic forest area > population > per grain output > slope of the research area > average annual precipitation > per cultivated land area>per output value of agriculture. Multiple linear regression analysis models indicate that overgrazing and overexploitation of the land are the main actuating factors causing soil erosion and ecological degradation, and the slope of the research area is the second.
