摘　　要：对堆肥腐熟程度的评估方法作了研究,首次提出以模糊数学为基础,综合表观指数、碳氮比降解率、平均耗氧速率、微生物量、氨氮变化率等指标的模糊评估法。结果表明,该法全面、简便,有效地量化了堆肥的腐熟度。Research about the method of evaluating the degree of maturity for compost has been conducted. The comprehensive assessment method which was based on fuzzy mathematics and combination of several factors (apparent index, η C/N, BOD2, η NH4+-N and biomass) was first developed. The results showed that the method was comprehensive, convenient and effective in measuring the degree of maturity of compost.
