利用模拟宽波段数据定量反演关中平原土壤有机质含量研究
The Quantitative Retrieval of Soil Organic Matter Content in Guanzhong Plain by Using Wide Band Data
摘要
Abstract
Objective] With topsoil collected in Shanxi Yangling demonstration zone as the object, collecting soil samples and determining the organic matter content, and then combined with the corresponding field hyperspectral data and spectral response function, using wide band analog data, soil organic matter content was estimated.[Method] Through analysis of the intrinsic relationship between soil organic matter and spectrum, the sensitive bands were screened out, the model of estimating soil organic matter content was constructed; based on the wide band response func-tion and soil hyperspectral data, through the simulation of wide band data to construct the model for estimating soil organic matter content ; By comparing the hyperspectral data and simulated wide band, the feasibility of quantitative wide band remote sensing data for estimating soil organic matter content was studied.[Result] The results showed that the accuracy of soil organic matter was relatively high based on the wide band data . [Conclusion] Estimating soil organic matter content is feasible based on the wide band data, 2% is not the bottom line to estimate the soil organ-ic matter content based on spectral data.关键词
