| 中文摘要: |
| 土壤盐渍化危害极大且难治理，严重制约着土地资源利用与生态环境建设。本文针对天津滨海新区土壤盐渍化问题，从含量、分布、类型、纵向变化等方面分析了土壤盐渍化特征，探究了土壤盐渍化改良措施，旨在为天津市滨海新区土地资源规划、利用提供科学依据。结果表明:区内表层盐渍化土壤及盐土广布，面积合计约1743.20 km2；农用地表层盐渍化土壤及盐土合计约占全区农用地面积的52.94%；表层非盐渍化土壤以苏打型为主，轻度—重度盐渍化土壤以硫酸盐-氯化物型为主，盐土以氯化物型为主；春季土壤盐分剖面在坑塘水面、盐田、其他草地和裸土地等土地利用类型内主要表现为表聚型，在果园、水浇地和公园与绿地等土地利用类型内主要表现为底聚型；区内土壤盐渍化情况复杂，建议因地制宜，采取综合防治措施进行盐渍土改良。 |
| 英文摘要: |
| The harm of soil salinization was great and di.cult to be governed, which seriously restricted the utilization of land resources and the construction of ecological environment. For the problem of soil salinization in Binhai New Area, the soil salinization characteristics such as content characteristics, horizontal distribution characteristics, type characteristics and vertical variation characteristics were analyzed, and the improvement measures were discussed, which were aimed at providing the scienti.c basis for the planning and utilization of land resources in Binhai New Area, Tianjin. The results indicate that the surface salinized soil is widely developed with a total area of 1743.20 square kilometers in Binhai New Area. On agricultural land, the surface salinized soil is existed with 52.96 percent of the whole agricultural land in Binhai New Area. On the salinization type of surface soil, the non-salinized soil is mainly soda type, the lightly, moderately and heavily salinized soil is mainly sulphate-chloride type, and the solonchak is mainly chloride type. In spring, the soil salinity pro.les are top accumulation types in pond, salt .eld, other grassland and bare land etc., yet bottom accumulation types in irrigated land, orchard, parks and green space etc. As the situation of soil salinization is complicated in Binhai New Area, the improvement of soil salinization should be based on the local conditions, also taken the measures of comprehensive prevention and control. |
