| 摘 要： | 目的]揭示土壤水分对土壤光谱的影响机理,并为其他土壤参数的遥感监测提供理论支持。方法]以新疆塔里木盆地北缘渭干河—库车河三角洲野外光谱反射数据为研究对象,运用光谱分析法研究土壤水分光谱特征及土壤水分特征波段。结果]波长740、1 768、1 962、1 450、2 216 nm是土壤水分的吸收带。结论]土壤光谱反射率比变化主要依赖于土壤含水量状况和波长。在波长较短的部分,土壤反射率随土壤水分变化迅速,而对于波长较长的部分,水分的吸收起显著的作用,反射率变化缓慢。

| Abstract: | Objective] The research aimed to uncover the mechanism of moisture effects on soil spectral reflectance,and provide theoretical information for other soil properties spectral analysis and remote sensing monitoring.Method]The spectrum of delta oasis of Wigan and Kuqia rivers located in the north of Tarim basin were taken as study object.Continuum removal and statistical method were used to analyze soil moisture spectral characteristics.Result] The wavelength of 740,1768,1962,1450 and 2 216 nm were soil moisture absorption bands.Conclusion] Soil spectral reflectance ratio changes mainly depended on the soil moisture status and wavelength.At shorter wavelengths,soil reflectance changed with soil moisture rapidly,but for the long wavelength part,moisture absorption played a significant role,and reflectance changed slowly. |
