Abstract:

In order to determine soil saline distribution characteristics of eastern coastal counties in Hebei, salinity and pH of topsoil were analyzed by the methods of locate sampling and ARC soft processing in the coastal areas of east Hebei. The results showed that: the salinity of topsoil was more than 0.20% in Tanghai and Hangu, and less than 0.10% in the coastal of Qinhuangdao. 1-2 levels (salinity>0.4%) agricultural land areas of about 4×104 hm2, mainly distributed in coastal counties of Tangshan. pH of topsoil was more than 8.0 in Lutai, Hangu, Tanghai, the average of pH was less than 7.0 in the coastal region of Qinhuangdao. Saline soil of the district was depth distribution along coastal strip, and the most distributed in the coastal of Tangshan.
