Application of Analytic Hierarchy Process in Assessment of Suitability of Returning Farmland to Grassland in Middle and Lower Reaches of Tarim River

In this paper, the principles and methods of the Analytic Hierarchy Process were used to access suitability of revert farmland in Middle and Lower Reaches of Tarim River. a quantitative analysis on index to confirm weight could offer gist to carry out returning farmland to forest and grassland in the region. The result of analytic hierarchy process accorded with the situations of middle and lower reaches of Tarim River. Thus the process provided an effective method for assigning weight to each index in assessing suitability of returningt farmland to grass and woodland and also provided an effective estimation gist for integrative assessment and spread.
