We took Gansu Province, which is the grain between production and marketing balance area and is consisted of 14 cities (incluging 2 Autonomous prefectures), as the study area and divided non-food cultivated land negative external benefit into two major categories of food security and ecological environment. We used the integrated application of the negative external benefit calculation method to calculate the negative external benefit of non-food cultivated land of study area. We used spatial analysis function of ArcGIS 9.2 and GeoDa to analyze the clustering characteristics and differentiation trend of the negative external benefit of non-food cultivated land in the study area. The results show that:(1) the negative external benefit of non-food cultivated land in the study area is 27 billion 141 million yuan, the negative external benefits of non-food cultivated land in food security accounted for 79.25%, and the negative external benefits of non-food cultivated land in ecological environment accounted for 20.75%; (2) the negative externalities of non-food cultivated land in different regions of the study area were different, and the negative external benefit of cultivated land in Jiuquan City was the highest, which was 5.668 billion yuan, the lowest was found in Jiayuguan City, 104 million Yuan for this city, and the difference was 56 times; (3) in space, cities which the unit negative external benefits of non-food cultivated land were closer presented the concentrated distribution trend, cities with the higher negative external benefits of non-food cultivated land concentrated in the Hexi Corridor Area of irrigated agriculture; (4) the spatial variation of safety negative external benefit and the ecological environment negative external benefit of non-food cultivated land in study area were basically consistent, showing the high level in the west and the low level in the east, high level in the north and low level in the south. The scientific measure for the farmland non-staple negative external benefit and analysis on its spatial distribution characteristics of farmland are non-staple negative external benefit, and studies on the new exploration for ensuring the grain safety and the rational allocation of regional agricultural land use structure have important guiding significance.
