以11地市（区）2002年、2004年和2006年统计数据为基础，采用能值分析法分析陕西省区域耕地利用效益及其差异，得出关中地区能值投资率最高，陕南次之，陕北最低；净能值产出率陕南的汉中最高，关中地区次之，陕北最低；关中地区和陕北地区环境压力较大，陕南环境压力相对较小；11地市（区）的能值投资率呈现递增趋势：净能值产出率趋势递减；环境压力日趋增大。耕地利用效益关中地区和陕南较好，陕北最差。
以11地市（區）2002年、2004年和2006年統計數據為基礎，採用能值分析法分析陝西省區域耕地利用效益及其差異，得齣關中地區能值投資率最高，陝南次之，陝北最低；淨能值產齣率陝南的漢中最高，關中地區次之，陝北最低；關中地區和陝北地區環境壓力較大，陝南環境壓力相對較小；11地市（區）的能值投資率呈現遞增趨勢：淨能值產齣率趨勢遞減；環境壓力日趨增大。耕地利用效益關中地區和陝南較好，陝北最差。

Based on the statistics of 11 areas of Shanxi Province in 2002, 2004 and 2006,this paper analyzes the regional differences of cultivated land use of Shanxi Province with the method of Energy Analysis,with the results that Guanzhong region has the highest ratio of energy input,followed in turn by southern and northern regions of Shanxi Province,that Hanzhong City has the highest net energy output ratio, followed respectively by Guanzhong region and the northern region of the province, and that Guanzhong and northern regions are confronted with greater environmental pressure than the southern region. The paper also points out that in the past years ,the energy input ratios of the 11 areas were on the rise ,the net energy output ratios decreased, and the environmental pressure grew. It is concluded that land use benefit in Guanzhong and southern regions is much better than that in the northern region.
