%X 为明确盐渍土改良利用方向,对上实东滩生态园区土壤、地表水、地下水多项理化性质进行了测定分析。结果表明,其土壤质地为壤质土；土壤碱化严重,酸碱度集中于8.0~8.5；土壤电导率较高,集中于0.2~0.6 mS/cm,水溶性盐分含量较高,集中于0.6~3.68 g/kg,且以氯化钠为主,仍有一定程度的盐渍化,土壤盐化程度与地下水矿化度呈正相关；土壤有效磷集中在20 mg/kg以下,有机质集中在2 g/kg以下,土壤主要养分总体含量较低,且其含量随土壤深度增加而降低；硝态氮含量正常,均在1~51 mg/kg范围内；综合评价得出,园区土壤以3类土为主,占比58.06%。研究结果对滨海地区的盐渍土管控和农业生态园建设有一定的指导意义。</br>Physicochemical properties of soil,surface and underground waters were analyzed to seek the proper ways of reforming and utilizing the salinized soils in SIIC Dongtan. The results showed that,for most of the soils,the pH was 8.0-8.5 and the EC was 0.2-0.6 mS/cm. Soluble salinity contents were 0.6-3.68 g/kg and mainly consisted of sodium chloride. The salinization of the soil was positively correlated with the underground water mineralization. The available phosphorus and organic matter were mainly under 20 mg/kg and 2 g/kg,respectively. The total content of main nutrients was low and decreased with soil depth. The nitrate nitrogen was 1-51 mg/kg. According to the comprehensive assessment,58.06% of the soils were in the third quality grade. The research results have guidance values to the management and monitoring of salinized soil in coastal region and the construction of agriculture ecological garden.
