　　为了解华北平原县域中低产田土壤养分状况及变化，以平乡县为例，在2008—2010年测土配方施肥项目数据基础上，结合二次土壤普查结果，采用常规统计分析方法进行研究。结果表明：2008年平乡县实施测土配方施肥以来，耕层土壤有机质、碱解氮、速效钾含量均呈上升趋势，分别增加了1.3 g/kg、2.5 mg/kg、5.6 mg/kg，有效磷变化不大，2008年和2010年全县耕层土壤有效磷分别为10.0 mg/kg、10.8 mg/kg。较二次土壤普查结果，2010年全县耕层土壤有机质、碱解氮、有效磷、有效铁、锰、铜、锌均有不同程度增加，其中以有效锰、锌增加最多，增长率分别达到218.6%和527.3%，有机质、碱解氮、有效磷、有效铁、铜分别增加了4.4 g/kg、0.9 mg/kg、3.5 mg/kg、1.3 mg/kg、0.34 mg/kg，速效钾降低了、50.4 mg/kg。本地区自实施测土配方施肥至2010年，耕层土壤有机质、碱解氮、速效钾含量均呈上升趋势，但有效磷变化不大。较二次土壤普查结果2010年全县耕层土壤除速效钾外，有机质、碱解氮、有效磷、有效铁、锰、铜、锌均有不同程度增加，其中以有效锰、锌增加最多。

The study is based on the data from the Formula Fertilization by Soil Testing and the Second Soil Survey, and adopts the conventional statistic analysis methods, it aims at investigating the soil nutrients situation and changes in Pingxiang County belong to county medium-low yield in the North China Plain. These results showed that, the soil organic matter, available N, K increased, and the available P had changed little, since that the Formula Fertilization by Soil Testing were implemented in Pingxiang County in 2008, the soil available P in 2008 and 2010 were 10.0 mg/kg, 10.8 mg/kg, respectively. Both of the soil organic matter and available N, P, Fe, Mn, Cu, Zn around the county in 2010 increased at different degrees compared with the results of the Second Soil Survey, and the available Mn, Zn among of above items raised the most with respective growth rates of 218.6%and 527.3%. The soil organic matter and available N, P, Fe, Cu had added 4.4 g/kg, 0.9 mg/kg, 3.5 mg/kg, 1.3 mg/kg, 0.34 mg/kg, respectively, available K had reduced 50.4 mg/kg. The soil organic matter and available N, K of plough layer around the county increased, and the change of available P was small form 2008 to 2010. The soil organic matter and available N, P, Fe, Mn, Cu, Zn of plough layer around the county in 2010 increased at different degrees compared with the results of the Second Soil Survey, and the available Mn, Zn among of above items raised the most.
