soil texture index

In this paper,two kinds of land degradation indicators,named sandy soil index(SSI) and soil degradation index(SDI),are proposed based on Hyperion Data.

提出了两种针对Hyperion数据的土地退化指数计算方法:沙化土壤指数(SSI)和土壤退化指数(SDI),并以典型地区的数据进行验证。

Based on the Hyperion data as well as under the inspiration of soil line, reflectance curve characteristic, spectral match and spectral angle mapper, this paper brings forward two kinds of land degradation indicators which are called sandy soil index (SSI) and soil degradation index (SDI).

本文以高光谱Hyperion影像为数据源,在研究分析土壤反射光谱特征的基础上,结合土壤线原理、光谱匹配技术以及光谱角制图原理,提出两种针对Hyperion数据的土地退化指数:沙化土壤指数(SSI)和土壤退化指数(SDI),实验表明这两种指标不但能够真实的反映出地面土地退化信息情况,为土地的可持续利用服务,并且简单方便、切实可行。
