As one of important works in the agricultural sciences, the land suitability for farming is premise of economic activity, and has great significance on the land resource management and utilization.In this paper, the key natural factors that affecting farming land were selected to establish the index system of land suitability for farming.Applying geographical information system (GIS) grid technology, land suitability for farming index of Liaoning Province was calculated by using methods of comprehensive weighted score and analytic hierarchy process (AHP).Using land suitability for farming index, the availability of land for farming in Liaoning Province level was evaluated.The results showed that there was large acreage of land not fit to farming in the northwestern and southeastern of Liaoning Province.The degrees of land suitability for farming were reduced from middle part to northwestern and southeastern of Liaoning Province.Based on geo-statistics method of GIS, it showed that Shenyang and Panjin had high degree of land suitability for farming, while Chaoyang and Dandong had low degree of land suitability for farming.Comparing to the practical situation of land conditions in Liaoning Province, the results showed that the research had a higher rationality, can be used for land development and management services in Liaoning Province.
