摘  要:
了解土壤属性(SOM、N、P等)对于指导施肥、农业生产和农业调查中都有重要的作用。对黑龙江省绥化市附近黑土区范围内采集土壤样品进行研究,在ASTER遥感影像中获取对应采样点的光谱值,将土壤有机质、总氮含量和遥感影像光谱值进行逐步回归分析,得出影像反射光谱值与有机质含量之间指数关系式;与总氮含量确定为对数关系。根据建立的模型进行有机质和总氮含量制图。这个模型可以作为土壤参数估测和评价的参考,有一定的实际意义和应用价值。

摘  要:
The soil properties (SOM、N、P) are a significant meaning to guide fertilizer and agricultural production and investigation. Soil samples were collected in black soil area from Suihua region of Heilongjiang province, Northeast China. Soil reflectance corresponding samples place in ASTER remote sensing were obtained base on GPS data. The statistical relationship between SOM content and spectral value in ASTER data was fit to a exponent equation, logarithm expression about total N and reflectance. The maps may be used as reference of estimation of soil parameters.
