    Abstract:

    We established a land quality indicator system for Chongqing area of the Three Gorges Reservoir Region,using the press-state-response frame(abbreviated as PSR).The pressure index include rainfall,soil erodibility, terrain,land,population and income pressure, etc.;The condition index include soil ero- sion,fertility and pattern condition;The response index include usage and policy response. The land quality of the Three Gorges Reservoir region was primarily evaluated with the method of experts scoring,hierarchical assignment and comprehensive evaluation. The result indicates that the land quality synthesis score of Three Gorges Reservoir region is 2. 76 points, i. e.,the land quality is somewhat low. The scores of pres- sure,condition and response index are 2. 14,3. 13 and 3. The low land quality can be interpreted by the human interference and widely distributed purple soil and steep slope. Finally we hope that this work can provide land quality evaluation and ecological restoration with some methods and references.
