%X As the cultivation of land is contracted by farmers, the tendency of the separation of rural land is becoming obvious, resulting in the yearly increase of cropland ridge coefficient. Factors affecting the change of cultivated land mainly involve types of landforms, slope, selected sample plot, representative of sample, number of sample, size of sample and accuracy of measurement. Taking the most common phenomenon of separation of rural land in farmers’family as a study case, this paper has explored various influencing factors of the cropland ridge coefficient weights using AHP (Analytical Hierarchy Process). The investigated farmers at present live in 109 administrative villages and towns in Yong Chang county in Hexi corridor region, and 10 administrative divisions are selected as the sample data base. On the basis of analyzing the data of samples, a deep investigation of farmers’willing towards the separation of rural land and the allocation of farm land with contracted system based on land classification has also been made. The results indicate that the cropland ridge coefficient on the most farmers’part has significantly increased, but the number of actual cultivated land has decreased after analysis of the separation of rural land. The final conclusion is that because farmers are the main economic subject with strong independence, their behaviors are often associated with external and persistent influence on the increase of cropland ridge coefficient as well as the decrease of actual cultivated land. Therefore, the result of separation of rural land will affect the cropland ridge coefficient as well as actual arable land and the intensive development of land in large scale. However, farmland classification can effectively reduce the coefficient of cropland ridge, minimize the fragmentation, increase the arable land planting efficiency and reduce the agricultural costs. The survey data also show that farmers have a strong willing to allocate the farmland by the division of land classification, hoping that the Government could promote large-scale management of agricultural land and strengthen the transfer of the land to improve the farmers’awareness of protecting cultivated land and developing the land intensively.
