| 摘 要： | 采用电导率法对营口地区距海边不同距离的公路路肩的3层土壤进行含盐量测定,并且运用SPSS对其内在规律进行研究。结果表明:48个样本点的192份土样的电导率值均小于2.0 ds/m,即该地区的公路路肩1 m深度内土壤属于非盐渍化土壤;公路路肩土壤总的含盐量跟距海边距离、海拔有较弱负相关,与边沟含盐量和地下水矿化度呈弱的正相关,与蒸降差在20 cm有一定的负相关关系;利用TM卫星遥感图像获得48个采样点距离海边距离,并进行路肩土壤和距海边距离相关性的研究,得到回归方程。

| Abstract: | The survey and analysis of the salt content in the soil of road shoulder is critical to the plantation in the beach areas along highway.The Conductivity Law of 3-layer soil from Yingkou beach area of different contour intervals were examined to get the data of salt content in the soil.The research on the inner rules was also conducted with the method of the SPSS.The result indicated that the average conductivity of 192 soil samples in 48 sample spots,where the highway shoulder soil was the non-salt-alkaloid soil,was below 2.0 ds/m.The total salt content had weakly inverse proportion to the distance from the sea,the elevation.There are the certain weakly direct proportion to the residual quantity between the evaporation and rainfall in the area and the ground water was hardness index when it was at about 20 cm.The distance from the different sample spots to the sea were obtained by TM satellite remote sensing picture as well.And the relevant research between highway shoulder soil and distance from the sea were also carried out to obtain the regressive formula. |
