摘　　要：在对陕西省耕地数量变化趋势分析的基础上,从经济、科技和社会三个方面选取九项因子,构建耕地数量变化驱动因素指标体系,利用主成分分析法对影响耕地变化的因素进行了定量分析,得出影响陕西省耕地面积变化的驱动因素包括:经济发展因素、产业发展因素、科技因素和社会系统压力因素。On the basis of the changing trend of the amount of cultivated land in Shaanxi Province, nine factors are selected from the three aspects of economy, science ＆ technology, and society for the construction of the index system of numerical change motivation factor. Analytical method of primary factors is used for quantitative analysis of the changing factors of the changing cultivated land. It is concluded that the driving factors affecting the area change of cultivated land in Shaanxi Province include： the factor of economic development, the factor of industrial development, the factor of science and technology as well as the factor of pressure in social system.
