| 摘 要： | 本文选取pH、有机质、全氮、全磷、全钾、有效磷、速效钾、碱解氮构成河北省农地土壤肥力评价指标;并采用层次分析法确定土壤肥力评价指标的权重,运用模糊数学法对河北农地土壤肥力进行了综合评价。经与第二次土壤普查比较,研究发现:土壤pH值较高,有机质、全氮、碱解氮含量中等偏上,全磷、有效磷、全钾、速效钾含量较高,速效钾含量呈下降趋势;河北农地土壤肥力综合隶属度在0.739～0.862之间,其中唐山、衡水、石家庄、邯郸土壤综合肥力较高,廊坊、邢台土壤综合肥力有待提高。

| Abstract: | By taking pH,organic matter,total N,P,K,available P,K and N as assessment indicators of soil fertility in Hebei farming land,this paper adopts stratification analysis method to define the weight value of the assessment indicators of soil fertility,uses fuzzy comprehensive assessment to assess soil fertility in Hebei farming land.Compared with the results of the Second National Soil and Survey,the following conclusions were: soil pH was alkalinity.Organic matter,total N,available N content were higher than t... |
