摘  要：
以渤海湾地区滨海盐碱地为研究对象,对位于该区域的河北唐海、天津大港、河北黄骅、山东东营四个地区的盐碱土进行含水量、含盐量的动态分析.结果表明:0~20 cm土层含水量同20~40 cm、40~60 cm、60~80 cm土层相比,其含水量月变化较为剧烈;唐海、大港、黄骅土壤含水量在大多数月份均随土层深度增加而增加,东营土壤含水量的垂直分布较均匀.黄骅、东营土壤盐分具有较强的表聚性;大港土壤盐分含量随土层深度增加而增加;唐海土壤含盐量在各月份的空间分布无规律性.综上,4个地区土壤水分、盐分的动态变化无一致性规律表现.

摘  要：
This paper take the coastal salt and alkaline land in the Bohai Bay area as the studied object, the soil water content and soil salt content of Tanghai, Dagang, Huanghua and Dongying were analyzed dynamically. The results show that, inter-monthly variation of water content in 0～20 centimeter soil layer changed tempestuously compared with 20～40, 40～60 and 60～80 centimeter soil layer. Soil water content in Tanghai, Dagang, Huanghua increased with the increasing soil layer depth in most months, while soil water content in Dongying distributed evenly in vertical direction. Soil salinity in Huanghua, Dongying concentrated in the soil surface, soil salt content in Dagang increased with the increasing soil layer depth,and soil salt content in different month were without regularity in space distribution. It can be concluded that the water-salt movement were without regularity in four localities.
