Abstract

The Northern Yinchuan Plain is a productive agricultural area of northwest China, which is under threat due to soil salinization. According to the formation and restoring history of soil salinization, the analytic hierarchy process (AHP) was adopted for analyzing the causes of soil salinization and efficiency of various restoring measures. The calculated results of the relative weights of the indicators showed that semi-arid climate and parent material of soil are dominant factors of soil salinization, which account for40.1% and 21.4% respectively. Furthermore, afforestation and planting salt-tolerant plants and improving drainage system were better than other measures, the values were 38.4% and 29.9% respectively. The study showed that AHP method could provide meaningful references for preventing and improving soil salinization in the study area.
