摘要
以土壤容重、有机质和全氮等6个指标为主要影响因子,确定了河北平原土壤质量评价指标的单因素评价模型和评价指标的临界值体系.采用模糊数学方法,对河北平原土壤质量进行了综合评价.结果表明:河北平原土壤质量综合隶属度处于0.78～0.93;邯郸、衡水和石家庄3市的土壤综合质量较好,而廊坊和唐山2市的土壤综合质量稍差.
The paper discussed the application of fuzzy mathematics in integrated evaluation of soil quality of Hebei plain. By multi statistical analysis, 6 items of soil bulk density, organic matter, total N, etc. were confirmed as primary factors that affected soil quality of Hebei plain. Based on Hebei plain soil trait, single factor evaluating model of ever）, assessment indicators and the system of critical indicator of soil quality were established. The evaluating result indicated that soil quality of Hebei plain with the subordinative degree of 0. 78-0. 93 by fuzzy mathematics method.
