盐渍土

In this paper, two types of transport models widely used for water and salinity in soils are introduced; one is physical models, which include convection-dispersion Equation, stream tube model and HYDRUS developed by US Salinity Laboratory. At the same time, the parameter research is related to physical models. Another is system models, such as Transfer Function Model and BP-Network model. The resemblances and the differences among these modeling are compared and analyzed.

介绍了国内外目前应用较为广泛的几种水盐运移模型，包括对流－弥散模型、流管模型和美国国家盐渍土改良中心开发的HYDRUS模型等3种物理模型以及相关的模型参数研究；两种系统模型：传递函数模型和BP人工神经网络模型。

Today, the work is very successful in the reclamation and utilization of the salt-affected soils.

The aim was to provide theoretical basis for the biological improvement and utilization of coastal saline soil.

［目的］为滨海盐渍土的生物改良和利用提供理论依据。

The local and arboreal trees are the most in TEDA because the former of TEDA is salt marsh place and then transformed.

However, realizing the ways of the world, many complain that the demons grew strong and rich, just as cattle like salty soil; but by performing the sacrifice the gods attained the whole truth and triumph, as, analogically I might add, people will eventually realize that cattle as well as salt ruins the land.

然而，实现世界的方式，许多抱怨恶魔增长强劲和丰富的，就像牛一样盐渍土；但通过执行牺牲神实现全部真相和胜利，因为，我还可以补充analogically ，人们最终会认识到，牛以及盐废墟的土地。

Measuring method of the compressibility of the salty soil is roughly coextensive with the non-salty soil, which can adopt consolidation test.

其压缩性的测定方法与非盐渍土基本相同，可采用室内固结试验。

The results showed that the temporal-spatial distribution pattern did not alter basically from May 2002 to May 2006, and the topsoil congregative type of soil salinity profiles was the majority in the Yellow River Delta, which indicated that the risk of soil salinization was great, and the level of amelioration and rational utilization for saline soils needed to be improved further in the Yellow River Delta.

结果表明：从2002年到2006年，该地区土壤盐分剖面类型的空间分布格局基本没有改变，黄河三角洲土壤盐分剖面类型总体以表聚型为主，这表明黄河三角洲土壤盐渍化风险大，必须进一步提高盐渍土的治理和合理利用水平。

Correlation analysis showed that: medicago sativa various physiological indicators and the application of gypsum both have a good correlation, so gypsum on the coastal saline soil in the development and use of a very important role and significance.

相关性分析表明：苜蓿各项生理指标与脱硫石膏的施入量均有很好的相关性，因此脱硫石膏对滨海盐渍土的开发和利用有很重要的作用和意义。

The spatial variability of soil salt content, electrical conductivity, pH and sodium adsorption ratio was analyzed by using traditional statistics and geo-statistics in a typical degraded wetland of saline sodic soils.

以苏打盐渍土区典型退化湿地为研究区，运用经典统计学和地统计学相结合的方法研究了退化湿地盐碱化指标：土壤电导率、盐分含量、pH和钠吸附比的空间变异特征，绘制了4种指标的空间分布图。

P and K, indicating that Suaeda salsa is a kind of plant very strong in salt tolerance and its soil ameliorating effect on coastal saline soil is significant.
