摘　　要：土壤肥力演变规律、发展趋向及其调控对策是土壤科学研究的重点,文章归纳总结了目前研究作物产量所采用的方法和参数,重点阐述如何表征长期不同施肥下土壤生产力变化趋势及可持续性的研究现状,进一步分析长期不同施肥下作物产量时空变化特征及土壤地力贡献率特征方面的研究进展,并在此基础上提出了目前我国长期施肥下作物产量研究中存在的不足及今后发展方向。The soil fertility evolution, development trends, and the corresponding adjustment countermeasures were the keys of soil science research. This paper summarizes the current research on crop production methods and parameters and focuses on how to characterize the different long-term fertilization soil productivity changes in sustainability researches in order to further analyze the long-term fertilization crop yield characteristics of the temporal and special variations and research the contribution rate of the progress. Based on this research, improvement mechanisms regarding the long-term fertilization crop shortages in this country and future development directions were proposed.
