【摘要】 如何利用高光谱遥感技术快速、准确的监测土壤的理化特性是实现精准农业的必要前提,也是今后农业发展的必然趋势。本文综合国内外的研究结果较系统的阐述了土壤水分含量、土壤质地、土壤氧化铁含量、土壤有机质含量与土壤光谱特征的关系,并提出了该研究领域所存在的一些问题和今后的发展方向。更多还原

【Abstract】 It is necessary premise and inevitable trend to precise agriculture development with the high spectrum remote sensing technique supervised and measured physics-chemistry characteristic of soil quickly and accurately. The paper expatiated systemically the connection of spectrum characteristic with water content, texture, iron oxide, organic matter of soil and put forward the problem and development of the research domain.更多还原
