Abstract:

土壤盐渍化严重制约土地生产力,实时监测土壤盐渍化有利于农业正常生产。选择新疆渭干河—库车河绿洲的光谱反射率数据,研究不同程度盐渍化土壤的光谱特征;并对绿洲所在的库车县的环境与灾害监测预报小卫星的高光谱数据进行盐渍化信息提取。提取步骤为首先对土壤光谱反射率数据进行14种形式的变换,再与土壤含盐量进行相关分析、逐步回归分析,建立估算不同盐渍化程度的土壤含盐量方程,用均方根误差验证方程的精度;其次,建立植被和土壤波谱库;最后,在波谱库的数据基础上,使用波谱角分类法(SAM)对环境与灾害监测预报小卫星的高光谱数据进行分类。用同步实测数据对分类效果进行精度评价,效果较好,这一结果为今后该区域的高光谱应用奠定了基础,对区域农民耕作方式提出了警示,为区域可持续发展实践提供了参考。
