摘要
通过对淮海地区主要代表城市绿地土壤的理化特性进行取样分析对比,结果表明:该地区绿地土壤质地以壤质砂土、砂质壤土、壤质粘土为主,土壤硬度大致在10.42(±3.82)￣22.57(±9.37)kg·cm-2,基本能满足植物生长发育的需要;其土壤有机质及全量养分均低于当地农业土壤相应含量,并且其有效养分含量不均,土壤pH值7.26(±1.51)￣8.61(±1.66),向碱性的方向演变.另外,其土壤养分及化学性质之间有一定的相关性,各项指标间总体相关性较差.
The physichemical properties of urban greenland soil in Huaihai Zone were sampled and contrasted in this paper. The results showed that most of the greenland soil in this area is of loamy sand, sandy loam and loamy clay, The soil hardness is approximately about 10.42 （±3.82）-22.57 （±9.37）kg. cm^-2, and is enough for the growth of plants; the organic matter of the soil is lower than that of agriculture soil and the content of available nutrient is uneven. The pH value of the soil is 7.26 （±1.51）-8.61 （± 1.66）, which is partial to alkalescence. Besides, the available nutrient isn＇t even and the correlation among different nutrient is poor.
