| 摘 要： | 针对水布娅区域建立肥力综合级别模糊评判系统，利用水布娅早期监测资料，根据客观现状
利用较为成熟的标准肥力综合级别法单因子级别确定方法来建立隶属函数，并利用各肥力因子隔段测
值的变化来确定其权重值，进而利用所建立模糊评判系统，赋予土壤肥力一定的综合级别指标，结果
与标准综合级别法所得结果较为一致。本文所得结果还能较为清晰地知道不同级别的肥力分布情况，
以及综合级别指标值在各时间状态下的变化趋势。

| Abstract: | A comprehensive fuzzy assessment system for fertility grade is established for Shuibuya Region in Hubei Province;i.e.establishing the membership function through the way of determing single factor from the more mature method of standard comprehensive assessment on fertility grade,and then defining its weight with the changes of the interval measured values of all the fertility factors,furthermore,giving the soil fertility a certain comprehensive index with the established fuzzy assessment system;from which the result is more coincided with that from the method of standard comprehensive assessment on fertility grade.Generally,with the result from the study herein,the fertility distribution of different grades with the changing trends of the comprehensive grade index values under all the relevant temporal states can be more obviously obtained. |
