摘要： 以河南省获嘉县的粮食主产区为例，采用主成分分析法对不同养分调控措施对农田生态系统健康影响进行评价。主要评价指标体系涉及了土壤物理、化学、生物性状以及作物指标，共17个指标。结果表明，玉米秸秆还田和小麦秸秆还田都可以明显改善土壤的物理性质；而对土壤化学性质的影响较为复杂，但总体上有利于土壤有机质的积累和速效养分的提供与保持；有机肥的施用，使土壤的物理性质、化学性质和生物性状方面都得到一定程度的改善。

Abstract: In this paper, the agro-ecosystem health under different fertilization were evaluated using principal component analysis, by taking the Huojia County, the main grain producing areas of North Plain of China as case study. A index including 17 indicators relating soil physical, chemical and biological characteristics were constructed for evaluation. The results show that the corn straw and wheat straw returning to field can significantly improve the soil's physical properties, and help to the accumulation of soil organic matter and available nutrients to provide and maintain on the whole. In addition, organic manure application can improved the soil's physical, chemical biological properties to some extent.
