摘要:
土壤盐渍化敏感性评价可以评估可能发生的土壤盐渍化的类型、范围和程度。以博斯腾湖湖滨绿洲为研究区，以2010年ALOS遥感影像为基本数据源，结合野外调查和样品分析，采用监督分类法和试验数据统计分析方法，依据土壤盐渍化敏感性指数公式，计算不同土地利用类型的土壤盐渍化敏感性指数。研究结果表明：轻度、中度和重度盐渍地主要分布于博斯腾湖周边的湿地边缘和未利用地，总面积为643.26 km2，占研究区总面积的24.68%；未利用地土壤盐渍化敏感性指数为0.25，属于重度敏感区；耕地和沙地的土壤盐渍化敏感性指数为0.15，属于中度敏感区；湿地土壤盐渍化敏感性指数为0.13，属于轻度敏感区；水体土壤盐渍化敏感性为0.03，属于非敏感区。
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.
