Spatio-temporal Variability of Saline Soil Salinity in Shandong Low-lying Coastal Plain
摘要
Abstract
Statistical methods was adopted to analysis the spatio-temporal variation and spatial distribution difference of Shandong coastal saline soil in this paper.The results showed that the salinization degree of the Yellow River Delta is high and there is a trend of salt deposition on the inter-annual variability.The southern Laizhou Bay showed a trend of desalination while the salin-ization area is increasing.The influence of the structure factors of saline soil in the low-lying plain of Shandong province is aggravated and the top layer soil salinity distribution has a close relation-ship with topography,the salinization type is basically in accordance with the distribution charac-teristics of salinization degree.What's more,attention should be paid to prevent soil alkalization in the southern Laizhou bay.Suggestions were proposed according to these results,such as the com-prehensive exploitation,measures adjustment to local conditions to reduce soil salt input,salt-leaching strengthening,soil properties improvement and soil alkaline prevention,which are of im-portant guiding significance for the development and utilization of water and soil resources in coastal region.关键词
