摘要
分析了土壤生产力ＰＩ与ＦＰＩ模型的缺陷；在建立复垦土壤生产力机理模型的基础上，提出了复垦土壤生产力指数的修正模型ＭＰＩ，ＭＰＩ考虑了影响土壤生产力的因子间的相关性和时空变异性。通过实例说明了ＭＰＩ的优越性，并提出了ＭＰＩ评价复垦质量时应注意的问题。
Summary Available model of reclaimed soil productivity is of inevitably short for evaluating reclaimed soil Productivity. After developing a model To explain the mechanism of reclaimed soil, modified index model of reclaimed soil Productivity (MPI) is conducted. Interactions of factors, which affect reclaimed soil Productivity and their variability, are considered in MPI. An example for verifying the advantage of MPI is given in these paper.
