Distribution Characteristics of Soil Salinity in Absorbing Carbon Forest
摘要
Abstract
[Objective] The paper was to analyze the soil salinity characteristics in Xinjiang region, and develop salinization characteristic research , so as to provide reference for salinization research in arid region. [ Method] With different land types of soil vertical profiles in Kara-may absorbing carbon forest as research object, soil salinity and water soluble ions were determined and analyzed using statistical characteristic value and trend surface, and the distribution characteristic of soil salinity in the region was explored. [Result] The salinity in survey area of absorbing carbon forest mainly were sulfate-chloride type and chloride type, of which cations were mainly Na+ , K+ and Ca2+ , anions were CO32- , Cl- andSO42- , the variation coefficient of CO3 2- was as high as 292. 91, while the variation coefficient of Cl- was265.56. The variation of soil total soluble salts in the soil layer of 0 - 100 cm was not significant, indicating that the content in each soil layer was relatively stable. [ Conclusion ] The study provided basis for speeding up dynamic monitoring for soil salinization and finding the effective control approach against salinization.关键词
