| 摘 要： | 翅碱蓬(Suaeda salsa)是土壤盐渍化较为严重的地区常见的植被类型,研究翅碱蓬群落特征可以间接反映下方土壤的化学性质。通过野外采集的17个翅碱蓬野外光谱数据和相应土壤样品的理化分析数据,探讨了土壤化学性质和翅碱蓬野外光谱之间的关系。结果表明,翅碱蓬二阶导数光谱1 121nm波段可用来反映土壤有机质和全氮的含量变化,二阶导数光谱1 208nm波段可以很好地反映土壤全磷的含量变化,一阶导数光谱353nm波段可以很好地反映土壤速效钾的含量变化最好,二阶导数光谱724nm波段可以很好地反映土壤pH值的变化,而反映土壤盐分含量变化最好的为一阶导数光谱950nm,这为翅碱蓬覆盖的区域利用遥感技术进行土壤化学性质监测奠定了基础。

| Abstract: | Suaeda salsa is familiar in soil salinization area.Through studying Suaeda salsa community characteristics,soil chemical properties can be inferred.Suaeda salsa spectra and soil chemical property data were gotten through measuring seventeen paired-samples,which were used to study field spectra of Suaeda salsa in response to changes of soil chemical properties.The results showed that second derivative spectrum of 1 121 nm could be used to indicate changes of soil organic matter and soil total nitrogen,and se... |
