摘要
对成都经济区内的根系土壤样品进行了光谱测试分析。针对不同土壤类型和不同成土母质,总结了光谱特征,并对土壤分类做了初步的研究。结果表明:①violet(紫光)、blue(蓝光)光谱与根系土壤Cd含量都成正相关;②yellow(黄光)、orange(橙光)、redness(红光)波段光谱与根系土壤Cd含量呈负相关;③可以通过紫光、橙光的组合初步判断出土壤类型。
On the basis of spectrum test results of root system soil in the studied area, the authors summarized spectrum characteristics of the samples and made a pilot study on soil classification. The results show that ①violet and blue spectrum are positive coorelation with Cd of the root system soil in content;②yellow, orange and redness spectrum are negative coorelaticn with it; ③the soil type can be determined preliminarily by spectrum of the violet in combination with the orange.
