探讨了福建土壤养分的时、空变异及贫瘠化特征。分析认为： 除自然因素外， 人为因素在土壤贫瘠化特征的形成上占主导地位， 特别是侵蚀增加和耕作管理失调造成土壤养分循环与平衡的紊乱， 最终引起土壤贫瘠化。

This essay discusses the spatial-temporal distributions of soil impoverishment in Fujian province. The results of data analysis show that artificial interferences are main reasons for forming soil impoverishment except natural interferences itself. In those artificial reasons, increase of soil erosion and imbalance of cultivated land management cause disorders of soil nutrient cycle and balance, so soil impoverishment occurs. To counter these problem and situations, the author puts forward the macro-countermeasures.
