摘要

对我国不同土壤的激光诱导荧光光谱的研究表明

在可见光波段的荧光峰一般在450nm左右

其相对荧光强度与土壤有机质含量、粘粒含量、水分含量以及土壤的化学组成密切相关。还表明.测试环境的差异

并不改变土壤的荧光光谱特征

仅影响它的相对荧光强度;不同的植被覆盖度会明显引起土壤荧光光谱的相应变化。这些结果展示出了激光荧光遥感技术应用于土壤类型和某些性状探测的可能性。应用红光波段是识别植被和土壤的最佳荧光波段。

Abstract

The paper described the characteristics of laser induced fluorescence spectra （LIFS） of various soils in China. The results showed: 1) the peak in the visible wave band is at about the wavelength of 450 nm

and its relative intensity has close correlation with the contents of organic matter

clay or water as well as the chemical composition of soils

2) enviromemtal condition of measurement affects directly the relative fluorescence intensity of soil

but it does not change its features of LIFS

3) vegetation cover degree influnces LIFS significantly

It indicated the possibility that applying laser induced fluorescence technology of remote sensing to deteect soil types and some properties of soil. The red wave band is the optimum band to differentiate vegetations and soils.
