| 摘 要： | 以玛纳斯河流域绿洲农田为例，应用SPSS对绿洲内部不同开垦年限耕地土壤质量综合状况进行了主成分分析以及相关性分析。结果表明：土壤耕层综合质量状况随着开垦年限先变好，达到最优值后又开始退化，开垦10~15a严重退化，达到土壤耕作的预警期，随后进一步退化。通过综合评价分析，可以为防止农田退化，维护及恢复土壤地力提供参考依据。

| Abstract: | Based on farmland of the oasis in Manasi river valley, Statistical Package for Social Science (SPSS) was applied to carry out principal component analysis and correlated analysis about soil regime in different reclamation years. The result showed that , the plow layer of soil conditions went better in initial reclamation stage , then it began degrading after achieved optimization , and seriously degraded in 10 ~ 15 years which was the warning time. Through synthetic analysis, it could prevent farmland degeneration,provide consultation and theoretic foundation for soil fertility maintenance and recovery. |
