Abstract:: Sensitivity evaluation of soil salinization was used to evaluate the type, scope and degree of soil salinization. Taking lakeside oasis of Bosten Lake as a study area, using the ALOS remote sensing image in 2010, combing the field survey and supervised classification method, the classification of saline in the study area, and different land use types of soil salinization sensitivity index were calculated. From the perspective of saline soil distribution type, mild, moderate and severe saline soils mainly distributed in the study area. The unused land area was 643.26 km², accounting for 24.68% of total areas. Unused land salinization of soil sensitivity index was 0.25, belonging to severe saline soil area. Soil salinization sensitivity index of arable land and sandy land were 0.15, belonging to moderate saline soil area. Soil salinization in the wetland sensitivity index was 0.13, belonging to mild saline soil area. Soil sensitivity index of the water was 0.03, belonging to non-saline soil area.
