摘　　要：[目的]揭示京津冀果蔬基地土壤现状及问题。[方法]以饶阳县果园与蔬菜大棚土壤为评价对象,采集12个土壤样品,测定主要理化性质指标和盐碱度,并采用模糊评价法对土壤肥力进行综合评价。同时,采用综合质量影响指数评价法评价土壤重金属污染现状。[结果]饶阳果蔬基地土壤偏碱性,土壤出现了弱次生盐渍化现象,电导率随含盐量增加而增加,盐化的同时发生着碱化的现象。土壤肥力水平处于中等水平。土壤重金属污染评价结果显示,该研究区域出现了不同程度的重金属累积现象,这可能与施肥方式的不合理有关,具有潜在的风险,需引起重视。果园改为设施大棚蔬菜种植后明显降低了土壤有机质的含量,也增加了土壤盐碱化的风险。[结论]研究结果为饶阳县果蔬基地土地合理利用、合理施肥、土壤养分管理及优质果蔬生产提供科学依据。[Objective]To reveal the present situation and problems of soil in Beijing-Tianjin-Hebei fruit and vegetable base.[Method]Taking soil of Raoyang fruit and vegetable base as the evaluation object in Hebei Province,12 soil samples were collected,the main physical and chemical property indicators were determined,the soil salinity was evaluated,and correlation analysis was carried out;the fuzzy evaluation method was used to evaluate the soil fertility;the status of soil heavy metals was evaluated by the comprehensive quality impact index evaluation method.[Result]The soil in Raoyang fruit and vegetable base was alkaline,and the soil appeared weak secondary salinization.The electrical conductivity increased with the increase of salt content,and the phenomenon of alkalization occurred at the same time as the salinization.The soil fertility level was at a moderate level.The evaluation results of soil heavy metal pollution showed that different degrees of heavy metal accumulation occurred in the study area,which may be related to the unreasonable fertilization methods,which had potential risks and needs to be paid attention to.The conversion of orchards to greenhouse vegetable cultivation significantly reduced the content of soil organic matter and increased the risk of soil salinization.[Conclusion]The research results provide scientific basis for the rational use of land,rational fertilization,soil nutrient management and high-quality fruit and vegetable production in the fruit and vegetable base of Raoyang County.
