Study on the distribution and balance of the salt in the inland basin

In this article,based on the summary of the rsearch conclusion and the systematic analysis of the data of hydrology,soil,irrigation,water and salt,we use the systematic analysis measures,the water-salt movement theory and the water-salt balance principle to analyze and calculate the differ layers'salt distributing and the equation in the basin,the drainage basin, the irrigate region,the cropland and the soil profile.And we analyze,at the different levels of the inland basin,the formation and characteristic of "the salt drainage in the way". We think that "the salt drainage in dry way" is absolutely necessarily. We must consider the different outles and motivations of the "salt drainage in dry way"",so that it can solve effectively the salinization problem in the irrigated regions.
