基于高光谱数据的东北黑土带破坏现状与人类活动因素的相关性研究

Study on the Correlation between the Destruction Status and Human Activities in the Northeast Black Soil Belt Based on Hyperspectral Data

基于多源遥感影像、高光谱实测光谱反射率数据、指数产品等数据,构建基于高光谱数据的黑土有机质含量估算模型,基于综合光谱指数数据的黑土有机质预测,选择黑土有机质含量预测最优模型,反演黑土有机质空间格局,以居民点分布表征人类活动因素,探索研究东北黑土带破坏现状与人类活动因素的相关性。

In this paper,based on multi-source remote sensing image,hyperspectral reflectance data,index products and other data,an estimation model of black soil organic matter content based on hyperspectral data is constructed,and black soil organic matter prediction based on comprehensive spectral index data is conducted.The spatial pattern of black soil organic matter is inversed by using the optimal model of black soil organic matter content prediction,and the distribution of residential areas is used to characterize the factors of human activities.Explore and study the correlation between the destruction status of Northeast black soil belt and human activities.
