摘　　要：以松嫩平原典型区域（主要是黑龙江省大庆市）为研究对象，以面向对象分类方法将2000、2007和2014年三期TM／OLI遥感数据分类，得到遥感解译图像。分别以转换矩阵和LUCC模型归纳分析土地利用类型转化趋势。差异分析得出，土壤重度、中度、轻度盐渍化与农业用地间土地覆盖类型转换频繁；动态计算各种土地利用类型，2000～2007年农耕不合理导致土壤盐渍化面积增加，2007-2014年各种土地利用类型变化相对稳定。研究将遥感手段应用到土壤盐渍化监测中，为大庆市及整个松嫩平原盐渍化发展趋势判断、盐渍化治理及农业可持续发展提供科学依据。Taking typical region in Songnen Plain （Mainly Daqing city in Heilongjiang Province） as the research object, using 3 period （2000, 2007 and 2014） remote sensing data, adopted the object-oriented classification method, and then analyzed the trend of land use type conversion by the transformation matrix and LUCC model based on the interpretation of remote sensing image in the ENVI software. Research showed that, the difference analysis between severe, frequent change of land cover types with moderate, mild salinization and soil; the various types of land use between the dynamic calculation, from 2000 to 2007 due to the unreasonable farming soil salinization area increased; from 2007 to 2014, various types of land use change between the relatively stable. Remote sensing application was applied to soil salinization monitoring work, which will provide scientific basis for Songnen Plain development tendency, salinization control and sustainable development of agriculture.
