英文摘要	Models of soil reflectance for soil organic matter estimation are needed to quantify soil and vegetation spectral properties. The characteristics of Blacksoil in Songnen Plain, China, fit for quickly estimating organic matter content with hyperspectral reflectance models. Correlation analysis and multivariable statistical methods were used to build hyperspectral models for blacksoil organic matter content estimation, with spectral reflectance and its derivatives as independent variables and the Curvature and Ratio Indices introduced. Finally, the stability and capacity of the models were tested. The results are as follows: 620-810 nm bands are the main response spectrum of blacksoil organic matter, and the maximum is at 710 nm; normalizing spectral data partly eliminates the noises introduced when testing different samples; logtransforming SOM content improve the stability and prediction ability of the linear regression models; compared with other models, the multi-liner regression models are more stable and predictable; Normalized Spectra Derivate Multivariate Stepwise Linear Regression Model is the optimal one, and the Bow-curvature Linear Model is the most feasible one, the hyperspectral model can be used to measure blacksoil organic matter content quickly.
