  • In this paper, the numerical calculation of traditional land suitability evaluation is integrated with GISgraphical p rocession effectively. Taking Dongting Lake Region as an examp le, the soil erosion, environment,threaten of flooding and climate factor are four contestant factor through using paired comparison method to determinethe weight of each factor. Then the multi-factor evaluation method was used to evaluate the agricultural lands whichlocate in the Dongting Lake Region. Moreover, considering the special geographical location, the natural disasterweightwas increased for the reevaluation and itwas compared with the traditional evaluation for drawing some validconclusions.
